FORWARD-LOOKING INFORMATION

This Quarterly Report contains forward-looking statements relating to future events and future performance.  All statements other than those that are purely historical may be forward-looking statements.  In certain cases, forward-looking statements can be identified by the use of words such as "may," "will," "should," "expect," "anticipate," "believe," "intend," "project," "plan," "predict," "assume," "forecast," "estimate," "objective," "possible," "probably," "likely," "potential," "speculate," the negative of such words, or other similar expressions.

Although the Tennessee Valley Authority ("TVA") believes that the assumptions underlying any forward-looking statements are reasonable, TVA does not guarantee the accuracy of these statements.  Numerous factors could cause actual results to differ materially from those in any forward-looking statements.  These factors include, among other things:

The impact of the pandemic resulting from the outbreak of the Coronavirus Disease 2019 (“COVID-19”) on TVA's revenues, the demand for electricity, TVA’s workforce and operations, the availability of fuel and critical parts, supplies, and services, and the business and financial condition of TVA’s customers and counterparties;
The duration and severity of the COVID-19 pandemic, actions taken to contain its spread and mitigate its effects, and broader impacts of the COVID-19 pandemic on economic and market conditions, including impacts on interest rates, commodity prices, investment performance, and foreign currency exchange rates;
New, amended, or existing laws, regulations, or administrative orders or interpretations, including those related to environmental matters, and the costs of complying with these laws, regulations, or administrative orders or interpretations;
The cost of complying with known, anticipated, or new emissions reduction requirements, some of which could render continued operation of many of TVA's aging coal-fired generation units not cost-effective or result in their removal from service, perhaps permanently;
Significant reductions in demand for electricity produced through non-renewable or centrally located generation sources that may result from, among other things, economic downturns, increased energy efficiency and conservation, increased utilization of distributed generation and microgrids, and improvements in alternative generation and energy storage technologies;
Changes in customer preferences for energy produced from cleaner generation sources;
Changes in technology;
Actions taken, or inaction, by the U.S. government relating to the national or TVA debt ceiling or automatic spending cuts in government programs;
Costs or liabilities that are not anticipated in TVA's financial statements for third-party claims, natural resource damages, environmental cleanup activities, or fines or penalties associated with unexpected events such as failures of a facility or infrastructure;
Addition or loss of customers by TVA or the local power company customers ("LPCs");
Significant delays, cost increases, or cost overruns associated with the construction and maintenance of generation, transmission, navigation, flood control, or related assets;
Requirements or decisions changing the amount or timing of funding obligations associated with TVA's pension plans, other post-retirement benefit plans, or health care plans;
Increases in TVA's financial liabilities for decommissioning its nuclear facilities or retiring other assets;
Risks associated with the operation of nuclear facilities or other generation and related facilities, including coal combustion residuals ("CCR") facilities;
Physical attacks on TVA's assets;
Cyber attacks on TVA's assets or the assets of third parties upon which TVA relies;
The outcome of legal or administrative proceedings;
The failure of TVA's generation, transmission, navigation, flood control, and related assets and infrastructure, including CCR facilities, to operate as anticipated, resulting in lost revenues, damages, or other costs that are not reflected in TVA's financial statements or projections;
Differences between estimates of revenues and expenses and actual revenues earned and expenses incurred;
Weather conditions;
Catastrophic events such as fires, earthquakes, explosions, solar events, electromagnetic pulses ("EMP"), geomagnetic disturbances ("GMDs"), droughts, floods, hurricanes, tornadoes, or other casualty events or pandemics, wars, national emergencies, terrorist activities, or other similar events, especially if these events occur in or near TVA's service area;
Events at a TVA facility, which, among other things, could result in loss of life, damage to the environment, damage to or loss of the facility, and damage to the property of others;
Events or changes involving transmission lines, dams, and other facilities not operated by TVA, including those that affect the reliability of the interstate transmission grid of which TVA's transmission system is a part and those that increase flows across TVA's transmission grid;
Disruption of fuel supplies, which may result from, among other things, economic conditions, weather conditions, production or transportation difficulties, labor challenges, or environmental laws or regulations affecting TVA's fuel suppliers or transporters;
Purchased power price volatility and disruption of purchased power supplies;
Events which affect the supply of water for TVA's generation facilities;
Changes in TVA's determinations of the appropriate mix of generation assets;

5


Ineffectiveness of TVA's efforts at adapting its organization to an evolving marketplace and remaining cost competitive;
Inability to use regulatory accounting or loss of regulatory accounting approval for certain costs;
Inability to obtain, or loss of, regulatory approval for the construction or operation of assets;
The requirement or decision to make additional contributions to TVA's Nuclear Decommissioning Trust ("NDT") or Asset Retirement Trust ("ART");
Limitations on TVA's ability to borrow money which may result from, among other things, TVA's approaching or substantially reaching the limit on bonds, notes, and other evidences of indebtedness specified in the Tennessee Valley Authority Act of 1933 ("TVA Act");
An increase in TVA's cost of capital that may result from, among other things, changes in the market for TVA's debt securities, changes in the credit rating of TVA or the U.S. government, or, potentially, an increased reliance by TVA on alternative financing should TVA approach its debt limit;
Changes in the economy and volatility in financial markets;
Reliability or creditworthiness of counterparties;
Changes in the market price of commodities such as coal, uranium, natural gas, fuel oil, crude oil, construction materials, reagents, electricity, or emission allowances;
Changes in the market price of equity securities, debt securities, or other investments;
Changes in interest rates, currency exchange rates, or inflation rates;
Ineffectiveness of TVA's disclosure controls and procedures or its internal control over financial reporting;
Inability to eliminate identified deficiencies in TVA's systems, standards, controls, or corporate culture;
Inability to attract or retain a skilled workforce;
Inability to respond quickly enough to current or potential customer demands or needs;
Events at a nuclear facility, whether or not operated by or licensed to TVA, which, among other things, could lead to increased regulation or restriction on the construction, ownership, operation, or decommissioning of nuclear facilities or on the storage of spent fuel, obligate TVA to pay retrospective insurance premiums, reduce the availability and affordability of insurance, increase the costs of operating TVA's existing nuclear units, or cause TVA to forego future construction at these or other facilities;
Loss of quorum of the TVA Board of Directors ("TVA Board");
Changes in the priorities of the TVA Board or TVA senior management; or
Other unforeseeable events.

See also Item 1A, Risk Factors, and Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations in TVA's Annual Report on Form 10-K/A for the year ended September 30, 2019 (the "Annual Report"), and Part I, Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations, and Part II, Item 1A, Risk Factors in this Quarterly Report for a discussion of factors that could cause actual results to differ materially from those in any forward-looking statement.  New factors emerge from time to time, and it is not possible for TVA to predict all such factors or to assess the extent to which any factor or combination of factors may impact TVA's business or cause results to differ materially from those contained in any forward-looking statement.  TVA undertakes no obligation to update any forward-looking statement to reflect developments that occur after the statement is made.

1.  Summary of Significant Accounting Policies

General

The Tennessee Valley Authority ("TVA") is a corporate agency and instrumentality of the United States ("U.S.") that was created in 1933 by federal legislation in response to a proposal by President Franklin D. Roosevelt.  TVA was created to, among other things, improve navigation on the Tennessee River, reduce the damage from destructive flood waters within the Tennessee River system and downstream on the lower Ohio and Mississippi Rivers, further the economic development of TVA's service area in the southeastern U.S., and sell the electricity generated at the facilities TVA operates.

Today, TVA operates the nation's largest public power system and supplies power in most of Tennessee, northern Alabama, northeastern Mississippi, and southwestern Kentucky and in portions of northern Georgia, western North Carolina, and southwestern Virginia to a population of nearly 10 million people.

TVA also manages the Tennessee River, its tributaries, and certain shorelines to provide, among other things, year-round navigation, flood damage reduction, and affordable and reliable electricity. Consistent with these primary purposes, TVA also manages the river system and public lands to provide recreational opportunities, adequate water supply, improved water quality, cultural and natural resource protection, and economic development.

The power program has historically been separate and distinct from the stewardship programs.  It is required to be self-supporting from power revenues and proceeds from power financings, such as proceeds from the issuance of bonds, notes, or other evidences of indebtedness (collectively, "Bonds").  Although TVA does not currently receive congressional appropriations, it is required to make annual payments to the U.S. Department of the Treasury ("U.S. Treasury") as a return on the government's appropriation investment in TVA's power facilities (the "Power Program Appropriation Investment").  In the 1998 Energy and Water Development Appropriations Act, Congress directed TVA to fund essential stewardship activities related to its management of the Tennessee River system and nonpower or stewardship properties with power revenues in the event that there were insufficient appropriations or other available funds to pay for such activities in any fiscal year.  Congress has not provided any appropriations to TVA to fund such activities since 1999.  Consequently, during 2000, TVA began paying for essential stewardship activities primarily with power revenues, with the remainder funded with user fees and other forms of revenues derived in connection with those activities.  The activities related to stewardship properties do not meet the criteria of

12


an operating segment under accounting principles generally accepted in the United States of America ("GAAP").  Accordingly, these assets and properties are included as part of the power program, TVA's only operating segment.

Power rates are established by the TVA Board of Directors ("TVA Board") as authorized by the Tennessee Valley Authority Act of 1933, as amended ("TVA Act").  The TVA Act requires TVA to charge rates for power that will produce gross revenues sufficient to provide funds for operation, maintenance, and administration of its power system; payments to states and counties in lieu of taxes ("tax equivalents"); debt service on outstanding indebtedness; payments to the U.S. Treasury in repayment of and as a return on the Power Program Appropriation Investment; and such additional margin as the TVA Board may consider desirable for investment in system assets, retirement of outstanding Bonds in advance of maturity, additional reduction of the Power Program Appropriation Investment, and other purposes connected with TVA's business. TVA fulfilled its requirement to repay $1.0 billion of the Power Program Appropriation Investment with the 2014 payment; therefore, this item is no longer a component of rate setting.  In setting TVA's rates, the TVA Board is charged by the TVA Act to have due regard for the primary objectives of the TVA Act, including the objective that power shall be sold at rates as low as are feasible.  Rates set by the TVA Board are not subject to review or approval by any state or federal regulatory body.

Fiscal Year

TVA's fiscal year ends September 30.  Years (2020, 2019, etc.) refer to TVA's fiscal years unless they are preceded by "CY," in which case the references are to calendar years.

Cost-Based Regulation

Since the TVA Board is authorized by the TVA Act to set rates for power sold to its customers, TVA is self-regulated. Additionally, TVA's regulated rates are designed to recover its costs.  Based on current projections, TVA believes that rates, set at levels that will recover TVA's costs, can be charged and collected.  As a result of these factors, TVA records certain assets and liabilities that result from the regulated ratemaking process that would not be recorded under GAAP for non-regulated entities.  Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates.  Regulatory liabilities generally represent obligations to make refunds to customers for previous collections for costs that are not likely to be incurred or deferral of gains that will be credited to customers in future periods.  TVA assesses whether the regulatory assets are probable of future recovery by considering factors such as applicable regulatory changes, potential legislation, and changes in technology.  Based on these assessments, TVA believes the existing regulatory assets are probable of recovery.  This determination reflects the current regulatory and political environment and is subject to change in the future.  If future recovery of regulatory assets ceases to be probable, or any of the other factors described above cease to be applicable, TVA would no longer be considered to be a regulated entity and would be required to write off these costs.  All regulatory asset write-offs would be required to be recognized in earnings in the period in which future recovery ceases to be probable.

Basis of Presentation

TVA prepares its consolidated interim financial statements in conformity with GAAP for consolidated interim financial information. Accordingly, TVA's consolidated interim financial statements do not include all of the information and notes required by GAAP for annual financial statements. As such, they should be read in conjunction with the audited financial statements for the year ended September 30, 2019, and the notes thereto, which are contained in TVA's Annual Report on Form 10-K/A for the year ended September 30, 2019 (the "Annual Report"). In the opinion of management, all adjustments (consisting of items of a normal recurring nature) considered necessary for fair presentation are included on the consolidated interim financial statements.

The accompanying consolidated interim financial statements, which have been prepared in accordance with GAAP, include the accounts of TVA, wholly-owned direct subsidiaries, and variable interest entities ("VIE") of which TVA is the primary beneficiary. See Note 9Variable Interest Entities. Intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements requires TVA to estimate the effects of various matters that are inherently uncertain as of the date of the consolidated financial statements.  Although the consolidated financial statements are prepared in conformity with GAAP, TVA is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses reported during the reporting period.  Each of these estimates varies in regard to the level of judgment involved and its potential impact on TVA's financial results.  Estimates are considered critical either when a different estimate could have reasonably been used, or where changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact TVA's financial condition, results of operations, or cash flows.

Reclassifications

Certain historical amounts have been reclassified in the accompanying consolidated financial statements to the current presentation. In the March 31, 2019, Consolidated Statements of Cash Flows, amounts previously reported as $(10) million of Prepayment credits applied to revenue were reclassified to Other, net in cash flows from operating activities.

Cash, Cash Equivalents, and Restricted Cash

Cash includes cash on hand, non-interest bearing cash, and deposit accounts. All highly liquid investments with original maturities of three months or less are considered cash equivalents. Cash and cash equivalents that are restricted, as to withdrawal or use under the terms of certain contractual agreements, are recorded in Other long-term assets on the Consolidated Balance Sheets. Restricted cash and cash equivalents includes cash held in trusts that are currently restricted for TVA economic development loans and for certain TVA environmental programs in accordance with agreements related to compliance with certain environmental regulations. See Note 20Contingencies and Legal ProceedingsLegal Proceedings Environmental Agreements.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported on the Consolidated Balance Sheets and Consolidated Statements of Cash Flows:

Due to recent higher volatility in the financial markets associated with the Coronavirus Disease 2019 ("COVID-19") pandemic, TVA increased its target balance of Cash and cash equivalents in March 2020 by $500 million through short-term discount note issuances.

Allowance for Uncollectible Accounts

The allowance for uncollectible accounts reflects TVA's estimate of probable losses inherent in its accounts and loans receivable balances, excluding the EnergyRight® loans receivable.  TVA determines the allowance based on known accounts, historical experience, and other currently available information including events such as customer bankruptcy and/or a customer failing to fulfill payment arrangements after 90 days.  It also reflects TVA's corporate credit department's assessment of the financial condition of customers and the credit quality of the receivables. TVA continues to monitor the impact of the COVID-19 pandemic on accounts and loans receivable balances to evaluate the allowance for uncollectible accounts.

The allowance for uncollectible accounts was less than $1 million at both March 31, 2020, and September 30, 2019, for accounts receivable. Additionally, loans receivable of $137 million and $131 million at March 31, 2020, and September 30, 2019, respectively, are included in Accounts receivable, net and Other long-term assets, for the current and long-term portions, respectively, and are reported net of allowances for uncollectible accounts of less than $1 million at both March 31, 2020, and September 30, 2019.

Revenues

TVA recognizes revenue from contracts with customers to depict the transfer of goods or services to customers in an amount to which the entity expects to be entitled in exchange for those goods or services. For the generation and transmission of electricity, this is generally at the time the power is delivered to a metered customer delivery point for the customer's consumption or distribution. As a result, revenues from power sales are recorded as electricity is delivered to customers. In addition to power sales invoiced and recorded during the month, TVA accrues estimated unbilled revenues for power sales provided to five customers whose billing date occurs prior to the end of the month.  Exchange power sales are presented in the accompanying Consolidated Statements of Operations as a component of sales of electricity. Exchange power sales are sales of excess power after meeting TVA native load and directly served requirements.  Native load refers to the customers on whose behalf a company, by statute, franchise, regulatory requirement, or contract, has undertaken an obligation to serve. TVA engages in other arrangements in addition to power sales. Certain other revenue from activities related to TVA's overall mission are recorded in Other revenue. Revenues that are not related to the overall mission are recorded in Other income (expense), net.

Leases

TVA recognizes a lease asset and lease liability for leases with terms of greater than 12 months. Lease assets represent TVA's right to use an underlying asset for the lease term, and lease liabilities represent TVA's obligation to make lease

14


payments arising from the lease, both of which are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date.  TVA has certain lease agreements that include variable lease payments that are based on energy production levels. These variable lease payments are not included in the measurement of the lease assets or lease liabilities but are recognized in the period in which the expenses are incurred.
    
While not specifically structured as leases, certain power purchase agreements are deemed to contain a lease of the underlying generating units when the terms convey the right to control the use of the assets. Amounts recorded for these leases are generally based on the amount of the scheduled capacity payments due over the remaining terms of the power purchase agreements, the terms of which vary. The total lease obligation included in Accounts payable and accrued liabilities and Operating lease liabilities related to these agreements was $296 million at March 31, 2020.

TVA has agreements with lease and non-lease components and has elected to account for the components separately. Consideration is allocated to lease and non-lease components generally based on relative standalone selling prices.

TVA has lease agreements which include options for renewal and early termination. The intent to renew a lease varies depending on the lease type and asset. Renewal options that are reasonably certain to be exercised are included in the lease measurements. The decision to terminate a lease early is dependent on various economic factors. No termination options have been included in TVA's lease measurements.
    
Leases with an initial term of 12 months or less, which do not include an option to extend the initial term of the lease to greater than 12 months that TVA is reasonably certain to exercise, are not recorded on the Consolidated Balance Sheets at March 31, 2020.
 
Operating leases are recognized on a straight-line basis over the term of the lease agreement. Rent expense associated with short-term leases and variable leases is recorded in Operating and maintenance expense, Fuel expense, or Purchased power expense on the Consolidated Statements of Operations. Expenses associated with finance leases result in the separate presentation of interest expense on the lease liability and amortization expense of the related lease asset on the Consolidated Statements of Operations.

Depreciation    

TVA accounts for depreciation of its properties using the composite depreciation convention of accounting. Under the composite method, assets with similar economic characteristics are grouped and depreciated as one asset. Depreciation is generally computed on a straight-line basis over the estimated service lives of the various classes of assets. The estimation of asset useful lives requires management judgment, supported by external depreciation studies of historical asset retirement experience. Depreciation rates are determined based on the external depreciation studies. These studies are updated at least every five years. Depreciation expense was $407 million and $424 million for the three months ended March 31, 2020 and 2019, respectively. Depreciation expense was $946 million and $732 million for the six months ended March 31, 2020 and 2019, respectively. See Note 5Plant Closures for a discussion of the impact of plant closures.

2.  Impact of New Accounting Standards and Interpretations     

The following are accounting standard updates issued by the Financial Accounting Standards Board ("FASB") that TVA adopted during 2020:
Lease Accounting
Description
This guidance changes the provisions of recognition in both the lessee and lessor accounting models. The standard requires entities that lease assets ("lessees") to recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases with terms of more than 12 months, while also refining the definition of a lease. In addition, lessees are required to disclose key information about the amount, timing, and uncertainty of cash flows arising from leasing arrangements. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily depend on its classification as a finance lease (formerly referred to as capital lease) or operating lease. The standard requires both types of leases to be recognized on the balance sheet. Operating leases will result in straight-line expense, while finance leases will result in recognition of interest on the lease liability separate from amortization expense. The accounting rules for the owner of assets leased by the lessee ("lessor accounting") remain relatively unchanged.

The standard allows for certain practical expedients to be elected related to lease term determination, separation of lease and non-lease elements, reassessment of existing leases, and short-term leases. The standard is to be applied using a modified retrospective transition.
Effective Date for TVA
October 1, 2019
Effect on the Financial Statements or Other Significant Matters
TVA has elected the modified retrospective method of adoption effective October 1, 2019. Under the modified retrospective method of adoption, prior year reported results are not restated.

TVA recorded $205 million and $210 million of lease assets and lease liabilities, respectively, for operating leases in effect at the adoption date. The accounting for finance leases remained substantially unchanged. Adoption of the standard did not materially impact results of operations or cash flows.

TVA has elected to apply the following practical expedients:
 
Practical Expedient
Description
 
 
Package of transition practical expedients (for leases commenced prior to adoption date; expedients must be adopted as a package)
Do not need to (1) reassess whether any expired or existing contracts are leases or contain leases, (2) reassess the lease classification for any expired or existing leases, or (3) reassess initial direct costs for any existing leases.
 
 
Short-term lease expedient (elect by class of underlying asset)
Elect as an accounting policy to not apply the recognition requirements to short-term leases by asset class.
 
 
Existing and expired land easements not previously accounted for as leases
Elect to not evaluate existing or expired easements under the new guidance and carry forward current accounting treatment.
 
 
Comparative reporting requirements for initial adoption
Elect to apply transition requirements at adoption date, recognize cumulative effect adjustment to retained earnings in period of adoption, and not apply the new requirements to comparative periods, including disclosures.
 
 
 
 
 
 
Derivatives and Hedging - Improvements to Accounting for Hedging Activities
Description
This guidance better aligns an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements.
Effective Date for TVA
October 1, 2019
Effect on the Financial Statements or Other Significant Matters
TVA has adopted the standard on a prospective basis. The adoption of this standard did not have a material impact on TVA's financial condition, results of operations, or cash flows. TVA only uses hedge accounting under its foreign currency swap arrangements, and the adoption of this standard had no impact on those arrangements.
 
Customer's Accounting for Implementation Costs in a Cloud Arrangement That Is a Service Contract
Description
This guidance relates to the accounting for a customer's implementation costs in a hosting arrangement that is a service contract. The amendments align the requirements for capitalizing those implementation costs with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software and hosting arrangements that include an internal-use software license. The amendments also provide requirements for the classification of the capitalized costs and related expense and cash flows in the financial statements, the application of impairment guidance to the capitalized costs, and the application of abandonment guidance to the capitalized costs. Entities are required to apply the amendments either retrospectively or prospectively to all implementation costs incurred after the adoption date.
Effective Date for TVA
October 1, 2019
Effect on the Financial Statements or Other Significant Matters
TVA has adopted the standard on a prospective basis. Adoption of this standard did not have a material impact on TVA's financial condition, results of operations, or cash flows. TVA records qualified implementation costs in a cloud arrangement that is a service contract as a prepaid asset and amortizes the prepaid asset to Operating and maintenance expense based on the term of the contract.

16


The following accounting standards have been issued but at March 31, 2020, were not effective and had not been adopted by TVA:
Financial Instruments - Credit Losses
Description
This guidance eliminates the probable initial recognition threshold in current GAAP and, instead, requires an allowance to be recorded for all expected credit losses for certain financial assets that are not measured at fair value. The allowance for credit losses is based on historical information, current conditions, and reasonable and supportable forecasts. The new standard also makes revisions to the other than temporary impairment model for available-for-sale debt securities. Disclosures of credit quality indicators in relation to the amortized cost of financing receivables are further disaggregated by year of origination.
Effective Date for TVA
The new standard is effective for TVA's interim and annual reporting periods beginning October 1, 2020. While early adoption is permitted, TVA does not plan to adopt the standard early.
Effect on the Financial Statements or Other Significant Matters
TVA is working to develop a model to calculate the allowance for credit losses based on management's estimate of the losses expected to be incurred over the life of the asset. TVA is evaluating the potential impact of the changes on its consolidated financial statements and related disclosures.
 
Fair Value Measurement Disclosure
Description
The guidance changes certain disclosure requirements for fair value measurements. It removes certain disclosure requirements, such as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for timing of the transfers between levels; and the valuation processes for Level 3 fair value measurements.  Some disclosure requirements are added, such as the change in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements.
Effective Date for TVA
The new standard is effective for TVA's interim and annual reporting periods beginning October 1, 2020. While early adoption is permitted, TVA does not plan to adopt the standard early.
Effect on the Financial Statements or Other Significant Matters
TVA does not expect the adoption of this standard to have a material impact on TVA's financial condition, results of operations, or cash flows. TVA is evaluating the potential impact on related disclosures.
 
Reference Rate Reform
Description
The guidance provides temporary optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rates.
Effective Date for TVA
The new standard is effective for adoption at any time between March 12, 2020, and December 31, 2022. TVA currently plans to adopt the standard by December 31, 2022.
Effect on the Financial Statements or Other Significant Matters
TVA continues to review this standard and evaluate the impact of using an alternative reference rate instead of LIBOR in its interest rate swap contracts. TVA expects the adoption of the standard will simplify the accounting for any modifications to its interest rate swap contracts.

3.  Accounts Receivable, Net

Accounts receivable primarily consist of amounts due from customers for power sales.  The table below summarizes the types and amounts of TVA's accounts receivable:

above.

In response to the COVID-19 pandemic, the TVA Board approved the Public Power Support and Stabilization Program, which includes alternative wholesale payment arrangements for LPCs, on March 25, 2020. TVA is offering up to $1.0 billion of credit support to LPCs who demonstrate the need for temporary financial relief, through the deferral of a portion of LPCs' wholesale power payments owed to TVA. The program requires LPCs to apply monthly beginning in April 2020 for the deferral, which is subject to approval by TVA. If approved, TVA will establish a repayment schedule based on the LPC's need, not to exceed two years, and an initial repayment date will be approved by TVA no later than December 31, 2020. The earliest deferral may be related to the May bill, and no such deferrals are included in the balances above. As of May 4, 2020, $1 million of credit support has been approved under the Public Power Support and Stabilization Program.

5. Plant Closures

Background

TVA must continuously evaluate all generating assets to ensure an optimal energy portfolio that provides safe, clean, and reliable power while maintaining flexibility and fiscal responsibility to the people of the Tennessee Valley. Based on results of assessments presented to the TVA Board in 2019, the retirement of Paradise Fossil Plant ("Paradise") Unit 3 by December 2020 and Bull Run Fossil Plant ("Bull Run") by December 2023 was approved. Subsequent to the TVA Board approval, TVA determined that Paradise would not be restarted after January 2020 due to the plant's material condition. Paradise Fossil Plant Unit 3 was taken offline on February 1, 2020, effectively retiring the plant.

Financial Impact

As a result of TVA's decision to accelerate the retirements of Paradise and Bull Run, certain construction projects at these locations were identified as probable of abandonment or were no longer expected to be in service for greater than one year prior to the plants' retirement dates. The write-off of these projects resulted in $124 million of Operating and maintenance expense during the second quarter of 2019. TVA has since recognized a cumulative $34 million of Operating and maintenance expense related to other activities including certain regulatory compliance projects at these facilities. Of this amount, $3 million and $7 million were recognized during the three and six months ended March 31, 2020, respectively. TVA has also recognized a cumulative $21 million of Operating and maintenance expense related to materials and supplies inventory reserves and write-offs identified at Paradise. Of this amount, $2 million was recognized for both the three and six months ended March 31, 2020. Additional amounts for Bull Run may be written off during closure activities.

TVA's policy is to adjust depreciation rates to reflect the most current assumptions, ensuring units will be fully depreciated by the applicable retirement dates. As a result of TVA's decision to accelerate the retirement of Paradise and Bull Run, TVA has recognized a cumulative $882 million of accelerated depreciation, with $91 million and $316 million being recognized during the three and six months ended March 31, 2020, respectively.

6. Leases

As described in Note 2Impact of New Accounting Standards and Interpretations, TVA has elected the modified retrospective method of adoption for the new lease accounting standard effective October 1, 2019. Under the modified retrospective method of adoption, prior year reported results are not restated.

TVA recorded $205 million and $210 million of lease assets and lease liabilities, respectively, for operating leases in effect at the adoption date. The accounting for finance leases remained substantially unchanged. Adoption of the standard did not materially impact results of operations or cash flows.

Notes
(1) Costs are included in Operating and maintenance expense, Fuel expense, and Purchased power expense on the Consolidated Statements of Operations. TVA's rental expense for operating leases was approximately $18 million and $36 million for the three and six months ended March 31, 2019, respectively.
(2) Expense is included in Depreciation and amortization expense on the Consolidated Statements of Operations.
(3) Expense is included in Interest expense on the Consolidated Statements of Operations.
(4) Certain finance leases receive regulatory accounting treatment and are reclassified to Fuel expense and Purchased power expense.

TVA's variable lease costs are related to renewable energy purchase agreements that require TVA to purchase all output from the underlying facility. Payments under those agreements are solely based on the actual output over the lease term. Certain TVA lease agreements contain renewal options. Those renewal options that are reasonably certain to be exercised are included in the lease measurements.

TVA has certain finance leases under power purchase agreements under which the present value of the minimum lease payments exceeds the fair value of the related lease asset at the date of measurement.  This resulted in an interest rate that was higher than TVA's incremental borrowing rate. At March 31, 2020, the weighted average remaining lease term in years and the weighted average discount rate for TVA's operating and financing leases were as follows:

Note
(1) The discount rate is calculated using the rate implicit in a lease if it is readily determinable. If the rate used by the lessor is not readily determinable, TVA uses its incremental borrowing rate as permitted by accounting guidance. The incremental borrowing rate is influenced by TVA's credit rating and lease term and as such may differ for individual leases, embedded leases, or portfolios of leased assets.

TVA entered into a power purchase agreement with a renewable resource provider for solar generation and rights to charge and discharge a battery energy storage system. The system is considered a lease component in this agreement. This lease has a term of 20 years, and is expected to commence on October 1, 2022. Payments made over the term of this lease are expected to total approximately $89 million.

EnergyRight® Receivables. In association with the EnergyRight® Solutions program, TVA's local power company customers ("LPCs") offer financing to end-use customers for the purchase of energy-efficient equipment. Depending on the nature of the energy-efficiency project, loans may have a maximum term of five years or 10 years. TVA purchases the resulting loans receivable from its LPCs. The loans receivable are then transferred to a third-party bank with which TVA has agreed to repay in full any loans receivable that have been in default for 180 days or more or that TVA has determined are uncollectible. Given this continuing involvement, TVA accounts for the transfer of the loans receivable as secured borrowings. The current and long-term portions of the loans receivable are reported in Accounts receivable, net and Other long-term assets, respectively, on TVA's Consolidated Balance Sheets. At March 31, 2020, and September 30, 2019, the carrying amount of the loans receivable,

21


net of discount, reported in Accounts receivable, net was $19 million and $20 million, respectively. See Note 10Other Long-Term Liabilities for information regarding the associated financing obligation.

In response to the COVID-19 pandemic, customers experiencing a financial hardship can request a deferral of loan payments for a period of up to six months. This deferral option is available beginning April 20, 2020, through October 31, 2020. Deferred loans will not accrue interest during the deferral months.

Prepaid Long-Term Service Agreements. TVA has entered into various long-term service agreements for major maintenance activities at certain of its combined cycle plants. TVA uses the direct expense method of accounting for these arrangements. TVA accrues for parts when it takes ownership and for contractor services when they are rendered. Under certain of these agreements, payments made exceed the value of parts received and services rendered. The current and long-term portions of the resulting prepayments are reported in Other current assets and Other long-term assets, respectively, on TVA's Consolidated Balance Sheets. At March 31, 2020, and September 30, 2019, prepayments of $1 million and $5 million, respectively, were recorded in Other current assets.

8.  Regulatory Assets and Liabilities

Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates.  Regulatory liabilities generally represent obligations to make refunds to customers for previous collections for costs that are not likely to be incurred or deferral of gains that will be credited to customers in future periods.  Components of regulatory assets and regulatory liabilities are summarized in the table below:

Note
(1) Amounts for Non-current regulatory liabilities were less than $1 million at March 31, 2020, and September 30, 2019, and are therefore not represented in the table above.

Due to recent higher volatility in the financial markets associated with the COVID-19 pandemic, TVA experienced unrealized losses related to its investment portfolios and derivative instruments for the six months ended March 31, 2020. TVA does not recognize unrealized gains and losses from the investment portfolios and derivative instruments within earnings but rather defers all such gains and losses within a regulatory liability or asset in accordance with its accounting policy. See Note 14Risk Management Activities and Derivative Transactions and Note 15Fair Value Measurements.

9.  Variable Interest Entities

A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of owning a controlling financial interest. When TVA determines that it has a variable interest in a VIE, a qualitative evaluation is performed to assess which interest holders have the power to direct the activities that most significantly impact the economic performance of the entity and have the obligation to absorb losses or receive benefits that could be significant to the entity. The evaluation considers the purpose and design of the business, the risks that the business was designed to create and pass along to other entities, the activities of the business that can be directed and which party can direct them, and the expected relative impact of those activities on the economic performance of the business through its life. TVA has the power to direct the activities of an entity when it has the ability to make key operating and financing decisions, including, but not limited to, capital investment and the issuance of debt. Based on the evaluation of these criteria, TVA has determined it is the primary beneficiary of certain entities and as such is required to account for the VIEs on a consolidated basis.

John Sevier VIEs

In 2012, TVA entered into a $1.0 billion construction management agreement and lease financing arrangement with John Sevier Combined Cycle Generation LLC ("JSCCG") for the completion and lease by TVA of the John Sevier Combined Cycle Facility ("John Sevier CCF"). JSCCG is a special single-purpose limited liability company formed in January 2012 to finance the John Sevier CCF through a $900 million secured note issuance ("JSCCG notes") and the issuance of $100 million of membership interests subject to mandatory redemption.  The membership interests were purchased by John Sevier Holdco LLC ("Holdco").  Holdco is a special single-purpose entity, also formed in January 2012, established to acquire and hold the membership interests in JSCCG.  A non-controlling interest in Holdco is held by a third party through nominal membership interests, to which none of the income, expenses, and cash flows are allocated. 
 
The membership interests held by Holdco in JSCCG were purchased with proceeds from the issuance of $100 million of secured notes ("Holdco notes") and are subject to mandatory redemption pursuant to a schedule of amortizing, semi-annual payments due each January 15 and July 15, with a final payment due in January 2042. The payment dates for the mandatorily redeemable membership interests are the same as those of the Holdco notes. The sale of the JSCCG notes, the membership interests in JSCCG, and the Holdco notes closed in January 2012. The JSCCG notes are secured by TVA's lease payments, and the Holdco notes are secured by Holdco's investment in, and amounts receivable from, JSCCG. TVA's lease payments to JSCCG are equal to and payable on the same dates as JSCCG's and Holdco's semi-annual debt service payments. In addition to the lease payments, TVA pays administrative and miscellaneous expenses incurred by JSCCG and Holdco. Certain agreements related to this transaction contain default and acceleration provisions.

Due to its participation in the design, business conduct, and credit and financial support of JSCCG and Holdco, TVA has determined that it has a variable interest in each of these entities. Based on its analysis, TVA has concluded that it is the primary beneficiary of JSCCG and Holdco and, as such, is required to account for the VIEs on a consolidated basis. Holdco's membership interests in JSCCG are eliminated in consolidation.

Southaven VIE

In 2013, TVA entered into a $400 million lease financing arrangement with Southaven Combined Cycle Generation LLC ("SCCG") for the lease by TVA of the Southaven Combined Cycle Facility ("Southaven CCF"). SCCG is a special single-purpose limited liability company formed in June 2013 to finance the Southaven CCF through a $360 million secured notes issuance ("SCCG notes") and the issuance of $40 million of membership interests subject to mandatory redemption. The membership interests were purchased by Southaven Holdco LLC ("SHLLC"). SHLLC is a special single-purpose entity, also formed in June 2013, established to acquire and hold the membership interests in SCCG. A non-controlling interest in SHLLC is held by a third party through nominal membership interests, to which none of the income, expenses, and cash flows of SHLLC are allocated.

The membership interests held by SHLLC were purchased with proceeds from the issuance of $40 million of secured notes ("SHLLC notes") and are subject to mandatory redemption pursuant to a schedule of amortizing, semi-annual payments due each February 15 and August 15, with a final payment due on August 15, 2033. The payment dates for the mandatorily redeemable membership interests are the same as those of the SHLLC notes, and the payment amounts are sufficient to provide returns on, as well as returns of, capital until the investment has been repaid to SHLLC in full. The rate of return on investment to SHLLC is 7.0 percent, which is reflected as interest expense on the Consolidated Statements of Operations. SHLLC is required to pay a pre-determined portion of the return on investment to Seven States Southaven, LLC ("SSSL") on each lease payment date as agreed in SHLLC's formation documents (the "Seven States Return"). The current and long-term portions of the Membership interests of VIE subject to mandatory redemption are included in Accounts payable and accrued liabilities and Other long-term liabilities, respectively.

The SCCG notes are secured by TVA's lease payments, and the SHLLC notes are secured by SHLLC's investment in, and amounts receivable from, SCCG. TVA's lease payments to SCCG are payable on the same dates as SCCG's and SHLLC's semi-annual debt service payments and are equal to the sum of (i) the amount of SCCG's semi-annual debt service payments, (ii) the amount of SHLLC's semi-annual debt service payments, and (iii) the amount of the Seven States Return. In addition to

23


the lease payments, TVA pays administrative and miscellaneous expenses incurred by SCCG and SHLLC. Certain agreements related to this transaction contain default and acceleration provisions.

In the event that TVA were to choose to exercise an early buy out feature of the Southaven facility lease, in part or in whole, TVA must pay to SCCG amounts sufficient for SCCG to repay or partially repay on a pro rata basis the membership interests held by SHLLC, including any outstanding investment amount plus accrued but unpaid return. TVA also has the right, at any time and without any early redemption of the other portions of the Southaven facility lease payments due to SCCG, to fully repay SHLLC's investment, upon which repayment SHLLC will transfer the membership interests to a designee of TVA.

TVA participated in the design, business conduct, and financial support of SCCG and has determined that it has a direct variable interest in SCCG resulting from risk associated with the value of the Southaven CCF at the end of the lease term. Based on its analysis, TVA has determined that it is the primary beneficiary of SCCG and, as such, is required to account for the VIE on a consolidated basis.

Impact on Consolidated Financial Statements

The financial statement items attributable to carrying amounts and classifications of JSCCG, Holdco, and SCCG at March 31, 2020, and September 30, 2019, as reflected on the Consolidated Balance Sheets, are as follows:

Creditors of the VIEs have no recourse to the general credit of TVA. TVA does not have any obligations to provide financial support to the VIEs other than as prescribed in the terms of the agreements related to these transactions.

10.  Other Long-Term Liabilities

Other long-term liabilities consist primarily of liabilities related to certain derivative agreements and finance leases, as well as liabilities for environmental remediation and liabilities under agreements related to compliance with certain environmental regulations.

Interest Rate Swap Liabilities. TVA uses interest rate swaps to fix variable short-term debt to a fixed rate. The values of these derivatives are included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. At March 31, 2020, and September 30, 2019, the carrying amount of the interest rate swap liabilities reported in Accounts payable and accrued liabilities was $105 million and $88 million, respectively. See Note 14Risk Management Activities and Derivative TransactionsDerivatives Not Receiving Hedge Accounting TreatmentInterest Rate Derivatives for information regarding the interest rate swap liabilities. As of March 31, 2020, interest rate swap liabilities increased $369 million as compared to September 30, 2019, primarily due to a decrease in interest rates resulting in higher mark-to-market values on future expected net cash flows.
 
EnergyRight® Financing Obligations. TVA purchases certain loans receivable from its LPCs in association with the EnergyRight® Solutions program. The current and long-term portions of the resulting financing obligations are reported in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA's Consolidated Balance Sheets. At March 31, 2020, and September 30, 2019, the carrying amount of the financing obligations reported in Accounts payable and accrued liabilities was $21 million and $23 million, respectively. See Note 7Other Long-Term Assets for information regarding the associated loans receivable.

In response to the COVID-19 pandemic, customers experiencing a financial hardship can request a deferral of loan payments for a period of up to six months. This deferral option is available beginning April 20, 2020, through October 31, 2020. Deferred loans will not accrue interest during the deferral months.

Paradise Pipeline Financing Obligation. TVA reserves firm pipeline capacity on an approximately 19-mile pipeline owned by Texas Gas, which serves TVA's Paradise Combined Cycle Plant. The capacity contract contains a lease component due to TVA's exclusive right to use the pipeline. TVA accounts for this lease component as a financing transaction. The current and long-term portions of the resulting financing obligation are reported in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA's Consolidated Balance Sheets. At both March 31, 2020, and September 30, 2019, related liabilities of less than $1 million were recorded in Accounts payable and accrued liabilities.

Accrued Long-Term Service Agreements. TVA has entered into various long-term service agreements for major maintenance activities at certain of its combined cycle plants. TVA uses the direct expense method of accounting for these arrangements. TVA accrues for parts when it takes ownership and for contractor services when they are rendered. Under certain of these agreements, parts received and services rendered exceed payments made. The current and long-term portions of the resulting obligation are reported in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA's Consolidated Balance Sheets. At March 31, 2020, and September 30, 2019, related liabilities of $13 million and $12 million, respectively, were recorded in Accounts payable and accrued liabilities.

11.  Asset Retirement Obligations

During the six months ended March 31, 2020, TVA's total asset retirement obligations ("ARO") liability increased $159 million as a result of periodic accretion and revisions in estimate, partially offset by settlement projects that were conducted during the period. The nuclear and non-nuclear accretion amounts were deferred as regulatory assets.  During the six months ended March 31, 2020, $84 million of the related regulatory assets were amortized into expense as these amounts were collected in rates. See Note 8Regulatory Assets and Liabilities. TVA maintains investment trusts to help fund its decommissioning obligations. See Note 15 Fair Value MeasurementsInvestment Funds and Note 20Contingencies and Legal ProceedingsContingenciesDecommissioning Costs for disclosure of the current balances of the trusts and a discussion of the trusts' objectives.

The revisions in non-nuclear estimates increased $120 million for the six months ended March 31, 2020. In November 2019, the Tennessee Department of Environment and Conservation ("TDEC") released amendments to its regulations which govern solid waste disposal facilities, including TVA's active Coal Combustion Residuals ("CCR") facilities covered by a solid waste disposal permit and those which closed pursuant to a TDEC approved closure plan. Such facilities are generally subject to a 30-year post-closure care period during which the owner or operator must undertake certain activities, including monitoring and maintaining the facility. The amendments will, among other things, add an additional 50-year period after the end of the

25


post-closure care period, require TVA to submit recommendations as to what activities must be performed during this 50-year period to protect human health and the environment, and require TVA to submit revised closure plans every 10 years. This regulatory revision resulted in an increase of $129 million, of which $38 million was related to operating CCR facilities and $91 million was related to inactive or closed CCR facilities.

12.  Debt and Other Obligations

The increase in short-term debt of approximately $1.0 billion is primarily a result of power bond maturities and increased short-term debt issuance to hold a higher cash balance. Due to recent higher volatility in the financial markets associated with the COVID-19 pandemic, TVA increased its target balance of Cash and cash equivalents by $500 million through discount note issuances.

Credit Facility Agreements

TVA has funding available under four long-term revolving credit facilities totaling $2.7 billion: a $150 million credit facility that matures on December 11, 2021, a $1.0 billion credit facility that matures on June 13, 2023, a $1.0 billion credit facility that matures on September 28, 2023, and a $500 million credit facility that matures on February 1, 2025. The interest rate on any borrowing under these facilities varies based on market factors and the rating of TVA's senior unsecured, long-term, non-credit-enhanced debt. TVA is required to pay an unused facility fee on the portion of the total $2.7 billion that TVA has not borrowed or committed under letters of credit. This fee, along with letter of credit fees, may fluctuate depending on the rating of TVA's senior unsecured, long-term, non-credit-enhanced debt. At March 31, 2020, and September 30, 2019, there were approximately $1.4 billion and $1.3 billion, respectively, of letters of credit outstanding under these facilities, and there were no borrowings outstanding. See Note 14Risk Management Activities and Derivative TransactionsOther Derivative InstrumentsCollateral.

TVA and the U.S. Treasury, pursuant to the TVA Act, have entered into a memorandum of understanding under which the U.S. Treasury provides TVA with a $150 million credit facility. This credit facility was renewed in 2019 with a maturity date of September 30, 2020. Access to this credit facility or other similar financing arrangements with the U.S. Treasury has been available to TVA since the 1960s. TVA can borrow under the U.S. Treasury credit facility only if it cannot issue Bonds in the market on reasonable terms, and TVA considers the U.S. Treasury credit facility a secondary source of liquidity. The interest rate on any borrowing under this facility is based on the average rate on outstanding marketable obligations of the U.S. with maturities from date of issue of one year or less. There were no outstanding borrowings under the facility at March 31, 2020. The availability of this credit facility may be impacted by how the U.S. government addresses the possibility of approaching its debt limit.

Lease/Leasebacks
    
TVA previously entered into leasing transactions to obtain third-party financing for 24 peaking combustion turbine units ("CTs") as well as certain qualified technological equipment and software ("QTE"). Due to TVA's continuing involvement with the combustion turbine facilities and the QTE during the leaseback term, TVA accounted for the lease proceeds as financing obligations. At March 31, 2020, and September 30, 2019, the outstanding leaseback obligations related to the remaining CTs and QTE were $223 million and $263 million, respectively. In March 2019, TVA made final rent payments under lease/leaseback transactions involving eight CTs, and TVA had previously acquired the equity interests related to these transactions. These transactions were terminated in July 2019. Final rent payments are scheduled to be made under the remaining CT lease/leaseback transactions on various dates from May 2020 to January 2022. TVA has already acquired the equity interests related to transactions involving eight of these CTs and will have the option to acquire the equity interests related to transactions involving the remaining eight CTs for additional amounts. In addition, on October 30, 2019, TVA provided notice of its intent to purchase the ownership interest in certain QTE. Repurchase payments are expected to be paid through a series of installments in 2021 and 2022, after which the associated leases will be terminated.

13.  Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) ("AOCI") represents market valuation adjustments related to TVA's currency swaps. The currency swaps are cash flow hedges and are the only derivatives in TVA's portfolio that have been designated and qualify for hedge accounting treatment. TVA records exchange rate gains and losses on its foreign currency-denominated debt and any related accrued interest in net income and marks its currency swap assets and liabilities to market through other comprehensive income (loss) ("OCI"). TVA then reclassifies an amount out of AOCI into net income, offsetting the exchange gain/loss recorded on the debt. During the three months ended March 31, 2020 and 2019, TVA reclassified $56 million of losses and $14 million of gains, respectively, related to its cash flow hedges from AOCI to Interest expense. During the six months ended March 31, 2020 and 2019, TVA reclassified $3 million of gains and $4 million of losses, respectively, related to its cash flow hedges from AOCI to Interest expense. See Note 14Risk Management Activities and Derivative Transactions.

TVA records certain assets and liabilities that result from the regulated ratemaking process that would not be recorded under GAAP for non-regulated entities. As such, certain items that would generally be reported in AOCI or that would impact the statements of operations are recorded as regulatory assets or regulatory liabilities. See Note 8Regulatory Assets and Liabilities for a schedule of regulatory assets and liabilities.  See Note 14Risk Management Activities and Derivative Transactions for a discussion of the recognition in AOCI of gains and losses associated with certain derivative contracts. See Note 15Fair Value Measurements for a discussion of the recognition of certain investment fund gains and losses as regulatory assets and liabilities.  See Note 19Benefit Plans for a discussion of the regulatory accounting related to components of TVA's benefit plans.
    
14.  Risk Management Activities and Derivative Transactions

TVA is exposed to various risks related to commodity prices, investment prices, interest rates, currency exchange rates, and inflation as well as counterparty credit and performance risks.  To help manage certain of these risks, TVA has historically entered into various derivative transactions, principally commodity option contracts, forward contracts, swaps, swaptions, futures, and options on futures.  Other than certain derivative instruments in its trust investment funds, it is TVA's policy to enter into these derivative transactions solely for hedging purposes and not for speculative purposes. TVA suspended its Financial Trading Program ("FTP") in 2014 and no longer uses financial instruments to hedge risks related to commodity prices; however, TVA plans to continue to manage fuel price volatility through other methods and to periodically reevaluate its suspended FTP program for future use of financial instruments.

Overview of Accounting Treatment

TVA recognizes certain of its derivative instruments as either assets or liabilities on its Consolidated Balance Sheets at fair value.  The accounting for changes in the fair value of these instruments depends on (1) whether TVA uses regulatory accounting to defer the derivative gains and losses, (2) whether the derivative instrument has been designated and qualifies for hedge accounting treatment, and (3) if so, the type of hedge relationship (for example, cash flow hedge).

The following tables summarize the accounting treatment that certain of TVA's financial derivative transactions receive:

Cash Flow Hedging Strategy for Currency Swaps

To protect against exchange rate risk related to three British pound sterling denominated Bond transactions, TVA entered into foreign currency hedges at the time the Bond transactions occurred.  TVA had three currency swaps outstanding at March 31, 2020, with total currency exposure of £600 million and expiration dates ranging from 2021 to 2043.

When the dollar strengthens against the British pound sterling, the exchange gain on the Bond liability and related accrued interest is offset by an equal amount of loss on the swap contract that is reclassified out of AOCI. Conversely, the exchange loss on the Bond liability and related accrued interest is offset by an equal amount of gain on the swap contract that is reclassified out of AOCI. All such exchange gains or losses on the Bond liability and related accrued interest are included in Long-term debt, net and Accounts payable and accrued liabilities, respectively. The offsetting exchange losses or gains on the swap contracts are recognized in AOCI. If any gain (loss) were to be incurred as a result of the early termination of the foreign currency swap contract, the resulting income (expense) would be amortized over the remaining life of the associated Bond as a component of Interest expense. The values of the currency swap liabilities are included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets.

Derivatives Not Receiving Hedge Accounting Treatment

Interest Rate Derivatives.  Generally TVA uses interest rate swaps to fix variable short-term debt to a fixed rate, and TVA uses regulatory accounting treatment to defer the mark-to-market ("MtM") gains and losses on its interest rate swaps. The net deferred unrealized gains and losses are classified as regulatory assets or liabilities on TVA's Consolidated Balance Sheets and are included in the ratemaking formula when gains or losses are realized. The values of these derivatives are included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets, and realized gains and losses, if any, are included on TVA's Consolidated Statements of Operations. For the three months ended March 31, 2020 and 2019, the changes in fair market value of the interest rate swaps resulted in the deferral of unrealized losses of $556 million and $99 million, respectively. For the six months ended March 31, 2020 and 2019, the changes in fair market value of the interest rate swaps resulted in the deferral of unrealized losses of $385 million and $209 million, respectively. These unrealized losses are primarily due to recent higher volatility in the financial markets associated with the COVID-19 pandemic.

Commodity Derivatives. TVA enters into certain derivative contracts for coal and natural gas that require physical delivery of the contracted quantity of the commodity. TVA marks to market all such contracts and defers the fair market values as regulatory assets or liabilities on a gross basis. At March 31, 2020, TVA's coal and natural gas contract derivatives had terms of up to two and four years, respectively.

Notes
(1) Offsetting amounts primarily include counterparty netting of derivative contracts, margin account deposits for futures commission merchants transactions, and cash collateral received or paid in accordance with the accounting guidance for derivatives and hedging transactions. There were no offsetting amounts on TVA's Consolidated Balance Sheets at either March 31, 2020, or September 30, 2019.
(2) Letters of credit of approximately $1.4 billion and $1.3 billion were posted as collateral at March 31, 2020, and September 30, 2019, respectively, to partially secure the liability positions of one of the currency swaps and one of the interest rate swaps in accordance with the collateral requirements for these derivatives.

Other Derivative Instruments

Investment Fund Derivatives.  Investment funds consist primarily of funds held in the Nuclear Decommissioning Trust ("NDT"), the Asset Retirement Trust ("ART"), the Supplemental Executive Retirement Plan ("SERP"), and the TVA Deferred Compensation Plan ("DCP"). See Note 15Fair Value MeasurementsInvestment Funds for a discussion of the trusts, plans, and types of investments. The NDT and ART may invest in derivative instruments which may include swaps, futures, options, forwards, and other instruments. At March 31, 2020, and September 30, 2019, the NDT held investments in forward contracts to purchase debt securities. The fair values of these derivatives were in net asset positions totaling $10 million and $22 million at March 31, 2020, and September 30, 2019, respectively.

Collateral.  TVA's interest rate swaps and currency swaps contain contract provisions that require a party to post collateral (in a form such as cash or a letter of credit) when the party's liability balance under the agreement exceeds a certain threshold.  At March 31, 2020, the aggregate fair value of all derivative instruments with credit-risk related contingent features that were in a liability position was $2.4 billion.  TVA's collateral obligations at March 31, 2020, under these arrangements were approximately $1.4 billion, for which TVA had posted approximately $1.4 billion in letters of credit. These letters of credit reduce the available balance under the related credit facilities.  TVA's assessment of the risk of its nonperformance includes a reduction in its exposure under the contract as a result of this posted collateral.

For all of its derivative instruments with credit-risk related contingent features:
    
If TVA remains a majority-owned U.S. government entity but Standard & Poor's Financial Services, LLC or Moody's Investors Service, Inc. ("Moody's") downgrades TVA's credit rating to AA or Aa2, respectively, TVA's collateral obligations would likely increase by $22 million, and

If TVA ceases to be majority-owned by the U.S. government, TVA's credit rating would likely be downgraded and TVA would be required to post additional collateral.

Counterparty Risk

TVA may be exposed to certain risks when a counterparty has the potential to fail to meet its obligations in accordance with agreed terms. These risks may be related to credit, operational, or nonperformance matters. To mitigate certain counterparty risk, TVA analyzes the counterparty's financial condition prior to entering into an agreement, establishes credit limits, monitors the appropriateness of those limits, as well as any changes in the creditworthiness of the counterparty, on an ongoing basis, and when required, employs credit mitigation measures, such as collateral or prepayment arrangements and master purchase and sale agreements.

Customers.  TVA is exposed to counterparty credit risk associated with trade accounts receivable from delivered power sales to LPCs, and from industries and federal agencies directly served, all located in the Tennessee Valley region. Of the $1.2

31


billion and $1.6 billion of receivables from power sales outstanding at March 31, 2020, and September 30, 2019, respectively, nearly all counterparties were rated investment grade. TVA is also exposed to risk from exchange power arrangements with a small number of investor-owned regional utilities related to either delivered power or the replacement of open positions of longer-term purchased power or fuel agreements. TVA believes its policies and procedures for counterparty performance risk reviews have generally protected TVA against significant exposure related to market and economic conditions. See Note 1Summary of Significant Accounting PoliciesAllowance for Uncollectible Accounts and Note 3Accounts Receivable, Net.

TVA had revenue from two LPCs that collectively accounted for 16 percent of total operating revenues for the three and six months ended March 31, 2020 and 2019.

Suppliers.  If one of TVA's fuel or purchased power suppliers fails to perform under the terms of its contract with TVA, TVA might lose the money that it paid to the supplier under the contract and have to purchase replacement fuel or power on the spot market, perhaps at a significantly higher price than TVA was entitled to pay under the contract. In addition, TVA might not be able to acquire replacement fuel or power in a timely manner and thus might be unable to satisfy its own obligations to deliver power.

Natural Gas. TVA purchases the majority of its natural gas requirements from a variety of suppliers under short-term contracts. In the event of nonperformance by these suppliers, TVA believes that it can obtain replacement natural gas.

Coal. To help ensure a reliable supply of coal, TVA had coal contracts with multiple suppliers at March 31, 2020. The contracted supply of coal is sourced from multiple geographic regions of the U.S. and is to be delivered via various transportation methods (e.g., barge, rail, and truck). Emerging technologies, environmental regulations, and low natural gas prices have contributed to weak demand for coal. As a result, coal suppliers are facing increased financial pressure, which has led to relatively poor credit ratings and bankruptcies. Continued difficulties by coal suppliers could result in consolidations, additional bankruptcies, restructuring, contract renegotiations, or other scenarios. TVA has received notification from certain coal suppliers that they are temporarily suspending operations due to the COVID-19 pandemic. TVA may experience issues in obtaining fuel supply for its coal-fired generation, which could be material.

Nuclear Fuel. Nuclear fuel is obtained predominantly through long-term uranium concentrate supply contracts, contracted conversion services, contracted enrichment services, or a combination thereof, and contracted fuel fabrication services. The supply markets for uranium concentrates and certain nuclear fuel services are subject to price fluctuations and availability restrictions. Supply market conditions may make procurement contracts subject to credit risk related to the potential nonperformance of counterparties. In the event of nonperformance by these or other suppliers, TVA believes that replacement uranium concentrate and nuclear fuel services can be obtained, although at prices that may be unfavorable when compared to the prices under the current supply agreements.

Purchased Power. TVA has a power purchase agreement that expires on March 31, 2032, with a supplier of electricity for 440 megawatts ("MW") of summer net capability from a lignite-fired generating plant. TVA has determined that the supplier has the equivalent of a non-investment grade credit rating; therefore, the supplier has provided credit assurance to TVA under the terms of the agreement.

Derivative Counterparties.  TVA has entered into physical and financial contracts that qualify as derivatives for hedging purposes, and TVA's NDT, ART, and qualified defined benefit pension plan have entered into derivative contracts for investment purposes. If a counterparty to one of the physical or financial derivative transactions defaults, TVA might incur substantial costs in connection with entering into a replacement transaction. If a counterparty to the derivative contracts into which the NDT, the ART, and the qualified pension plan have entered for investment purposes defaults, the value of the investment could decline significantly or perhaps become worthless. TVA has concentrations of credit risk from the banking, coal, and gas industries because multiple companies in these industries serve as counterparties to TVA in various derivative transactions. At March 31, 2020, all of TVA's currency swaps and interest rate swaps as well as all of the derivatives in the NDT and ART were with banking counterparties whose Moody's credit ratings were A3 or higher.

TVA classifies qualified forward coal and natural gas contracts as derivatives. See Derivatives Not Receiving Hedge Accounting Treatment above. At March 31, 2020, the coal contracts were with counterparties whose Moody's credit rating, or TVA's internal analysis when such information was unavailable, ranged from B2 to Ba1. At March 31, 2020, the natural gas contracts were with counterparties whose ratings ranged from Caa2 to A2. See Suppliers above for discussion of challenges facing the coal industry. TVA recognizes the oil and gas industry has been impacted as the result of the COVID-19 pandemic and the slowdown in demand. TVA will continue to monitor the impacts and affected credit ratings and enforce contract performance assurance provisions when applicable.

15.  Fair Value Measurements

Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the asset or liability's principal market, or in the absence of a principal market, the most advantageous market for the asset or liability in an orderly transaction between market participants. TVA uses market or observable inputs as the preferred source of values, followed by assumptions based on hypothetical transactions in the absence of market inputs.

Valuation Techniques

The measurement of fair value results in classification into a hierarchy by the inputs used to determine the fair value as follows:
Level 1
 
 
Unadjusted quoted prices in active markets accessible by the reporting entity for identical assets or liabilities.  Active markets are those in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing.
Level 2
 
 
 
Pricing inputs other than quoted market prices included in Level 1 that are based on observable market data and that are directly or indirectly observable for substantially the full term of the asset or liability.  These include quoted market prices for similar assets or liabilities, quoted market prices for identical or similar assets in markets that are not active, adjusted quoted market prices, inputs from observable data such as interest rate and yield curves, volatilities and default rates observable at commonly quoted intervals, and inputs derived from observable market data by correlation or other means.
Level 3
 
 
Pricing inputs that are unobservable, or less observable, from objective sources.  Unobservable inputs are only to be used to the extent observable inputs are not available.  These inputs maintain the concept of an exit price from the perspective of a market participant and should reflect assumptions of other market participants.  An entity should consider all market participant assumptions that are available without unreasonable cost and effort.  These are given the lowest priority and are generally used in internally developed methodologies to generate management's best estimate of the fair value when no observable market data is available.

A financial instrument's level within the fair value hierarchy (where Level 1 is the highest and Level 3 is the lowest) is based on the lowest level of input significant to the fair value measurement.

The following sections describe the valuation methodologies TVA uses to measure different financial instruments at fair value. Except for gains and losses on SERP and DCP assets, all changes in fair value of these assets and liabilities have been recorded as changes in regulatory assets, regulatory liabilities, or AOCI on TVA's Consolidated Balance Sheets and Consolidated Statements of Comprehensive Income (Loss). Except for gains and losses on SERP and DCP assets, there has been no impact to the Consolidated Statements of Operations or the Consolidated Statements of Cash Flows related to these fair value measurements.

Investment Funds

At March 31, 2020, Investment funds were comprised of $2.6 billion of equity securities and debt securities classified as trading measured at fair value. Equity and trading debt securities are held in the NDT, ART, SERP, and DCP. The NDT holds funds for the ultimate decommissioning of TVA's nuclear power plants. The ART holds funds primarily for the costs related to the future closure and retirement of TVA's other long-lived assets. The balances in the NDT and ART were $1.9 billion and $677 million, respectively, at March 31, 2020.

TVA established a SERP to provide benefits to selected employees of TVA which are comparable to those provided by competing organizations. The DCP is designed to provide participants with the ability to defer compensation until employment with TVA ends. The NDT, ART, SERP, and DCP funds are invested in portfolios of securities generally designed to achieve a return in line with overall equity and debt market performance.

The NDT, ART, SERP, and DCP are composed of multiple types of investments and are managed by external institutional investment managers. Most U.S. and international equities, U.S. Treasury inflation-protected securities, real estate investment trust securities, and cash securities and certain derivative instruments are measured based on quoted exchange prices in active markets and are classified as Level 1 valuations. Fixed-income investments, high-yield fixed-income investments, currencies, and most derivative instruments are non-exchange traded and are classified as Level 2 valuations. These measurements are based on market and income approaches with observable market inputs.

Private equity limited partnerships, private real asset investments, and private credit investments may include holdings of investments in private real estate, venture capital, buyout, mezzanine or subordinated debt, restructuring or distressed debt, and special situations through funds managed by third-party investment managers. These investments generally involve a three-to-four-year period where the investor contributes capital, followed by a period of distribution, typically over several years.

33


The investment period is generally, at a minimum, 10 years or longer. The NDT had unfunded commitments related to private equity limited partnerships of $209 million, unfunded commitments related to private real assets of $63 million, and unfunded commitments related to private credit of $10 million at March 31, 2020. The ART had unfunded commitments related to private equity limited partnerships of $129 million, unfunded commitments related to private real assets of $52 million, and unfunded commitments related to private credit of $5 million at March 31, 2020. These investments have no redemption or limited redemption options and may also impose restrictions on the NDT's and ART's ability to liquidate their investments. There are no readily available quoted exchange prices for these investments. The fair value of these investments is based on information provided by the investment managers. These investments are valued on a quarterly basis. TVA's private equity limited partnerships, private real asset investments, and private credit investments are valued at net asset values ("NAV") as a practical expedient for fair value. TVA classifies its interest in these types of investments as investments measured at net asset value in the fair value hierarchy.

Commingled funds represent investment funds comprising multiple individual financial instruments. The commingled funds held by the NDT, ART, SERP, and DCP consist of either a single class of securities, such as equity, debt, or foreign currency securities, or multiple classes of securities. All underlying positions in these commingled funds are either exchange traded or measured using observable inputs for similar instruments. The fair value of commingled funds is based on NAV per fund share (the unit of account), derived from the prices of the underlying securities in the funds. These commingled funds can be redeemed at the measurement date NAV and are classified as Commingled funds measured at net asset value in the fair value hierarchy.

Realized and unrealized gains and losses on equity and trading debt securities are recognized in current earnings and are based on average cost. The gains and losses of the NDT and ART are subsequently reclassified to a regulatory asset or liability account in accordance with TVA's regulatory accounting policy. See Note 1Summary of Significant Accounting PoliciesCost-Based Regulation and Note 8Regulatory Assets and Liabilities. TVA recorded unrealized gains and losses related to its equity and trading debt securities held during each period as follows:

Due to recent higher volatility in the financial markets associated with the COVID-19 pandemic, TVA experienced losses related to its ART and NDT investment portfolio for the six months ended March 31, 2020.  For the six months ended March 31, 2020, the NDT declined in value $258 million, of which $246 million was unrealized.  Even with the decline in investment value, however, TVA’s NDT funding as of March 31, 2020, was fully funded per the Nuclear Regulatory Commission’s (“NRC”) funding requirements.

Currency and Interest Rate Derivatives

See Note 14Risk Management Activities and Derivative TransactionsCash Flow Hedging Strategy for Currency Swaps and Derivatives Not Receiving Hedge Accounting Treatment for a discussion of the nature, purpose, and contingent features of TVA's currency swaps and interest rate swaps. These swaps are classified as Level 2 valuations and are valued based on income approaches using observable market inputs for similar instruments.

Commodity Contract Derivatives

Most of these contracts are valued based on market approaches which utilize short-term and mid-term market-quoted prices from an external industry brokerage service. A small number of these contracts are valued based on a pricing model using long-term price estimates from TVA's coal price forecast. To value the volume option component of applicable coal contracts, TVA uses a Black-Scholes pricing model which includes inputs from the forecast, contract-specific terms, and other market inputs. These contracts are classified as Level 3 valuations.

Nonperformance Risk

The assessment of nonperformance risk, which includes credit risk, considers changes in current market conditions, readily available information on nonperformance risk, letters of credit, collateral, other arrangements available, and the nature of master netting arrangements. TVA is a counterparty to currency swaps, interest rate swaps, commodity contracts, and other derivatives which subject TVA to nonperformance risk. Nonperformance risk on the majority of investments and certain exchange-traded instruments held by TVA is incorporated into the exit price that is derived from quoted market data that is used to mark the investment to market.

Nonperformance risk for most of TVA's derivative instruments is an adjustment to the initial asset/liability fair value. TVA adjusts for nonperformance risk, both of TVA (for liabilities) and the counterparty (for assets), by applying credit valuation adjustments ("CVAs"). TVA determines an appropriate CVA for each applicable financial instrument based on the term of the instrument and TVA's or the counterparty's credit rating as obtained from Moody's. For companies that do not have an observable credit rating, TVA uses internal analysis to assign a comparable rating to the counterparty. TVA discounts each financial instrument using the historical default rate (as reported by Moody's for CY 1983 to CY 2019) for companies with a similar credit rating over a time period consistent with the remaining term of the contract. The application of CVAs resulted in a less than $1 million decrease in the fair value of assets and a $1 million decrease in the fair value of liabilities at March 31, 2020.

Fair Value Measurements

The following tables set forth by level, within the fair value hierarchy, TVA's financial assets and liabilities that were measured at fair value on a recurring basis at March 31, 2020, and September 30, 2019. Financial assets and liabilities have been classified in their entirety based on the lowest level of input that is significant to the fair value measurement. TVA's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the determination of the fair value of the assets and liabilities and their classification in the fair value hierarchy levels.

TVA uses internal valuation specialists for the calculation of its commodity contract derivatives fair value measurements classified as Level 3. Analytical testing is performed on the change in fair value measurements each period to ensure the valuation is reasonable based on changes in general market assumptions. Significant changes to the estimated data used for unobservable inputs, in isolation or combination, may result in significant variations to the fair value measurement reported.

The carrying value of Cash and cash equivalents, Restricted cash and cash equivalents, and Short-term debt, net approximate their fair values.

The fair value for loans and other long-term receivables is estimated by determining the present value of future cash flows using a discount rate equal to lending rates for similar loans made to borrowers with similar credit ratings and for similar remaining maturities, where applicable. The fair value of long-term debt and membership interests of VIEs subject to mandatory redemption is estimated by determining the present value of future cash flows using current market rates for similar obligations, giving effect to credit ratings and remaining maturities.

16.  Revenue

Revenue from Sales of Electricity

TVA's revenue from contracts with customers is primarily derived from the generation and sale of electricity to its customers and is included in Revenue from sales of electricity on the Consolidated Statements of Operations. Electricity is sold primarily to LPCs for distribution to their end-use customers. In addition, TVA sells electricity to directly served industrial companies, federal agencies, and others.
LPC sales
Approximately 93 percent of TVA's revenue from sales of electricity for the three and six months ended March 31, 2020 was to LPCs, which then distribute the power to their customers using their own distribution systems. Power is delivered to each LPC at delivery points within the LPC's service territory. TVA recognizes revenue when the customer takes possession of the power at the delivery point. For power sales, the performance obligation to deliver power is satisfied in a series over time because the sales of electricity over the term of the customer contract are a series of distinct goods that are substantially the same and have the same pattern of transfer to the customer. TVA has no continuing performance obligations subsequent to delivery. Using the output method for revenue recognition provides a faithful depiction of the transfer of electricity as customers obtain control of the power and benefit from its use at delivery. Additionally, TVA has an enforceable right to consideration for energy delivered at any discrete point in time and will recognize revenue at an amount that reflects the consideration to which TVA is entitled for the energy delivered.

The amount of revenue is based on contractual prices approved by the TVA Board. Customers are invoiced monthly for power delivered as measured by meters located at the delivery points. The net transaction price is offset by certain credits available to customers that are known at the time of billing. Credits are designed to achieve objectives of the TVA Act and include items such as hydro preference credits for residential customers of LPCs, economic development credits to promote growth in the Tennessee Valley, wholesale bill credits to LPCs participating in the long-term Partnership Agreement, and interruptible credits allowing TVA to reduce industrial customer usage in periods of peak demand to balance system demand. Payments are typically due within approximately one month of invoice issuance.
 
Directly served customers
Directly served customers, including industrial customers, federal agencies, and other customers, take power for their own consumption. Similar to LPCs, power is delivered to a delivery point, at which time the customer takes possession and TVA recognizes revenue. For all power sales, the performance obligation to deliver power is satisfied in a series over time since the sales of electricity over the term of the customer contract are a series of distinct goods that are substantially the same and have the same pattern of transfer to the customer. TVA has no continuing performance obligations subsequent to delivery. Using the output method for revenue recognition provides a faithful depiction of the transfer of electricity as customers obtain control of the power and benefit from its use at delivery. Additionally, TVA has an enforceable right to consideration for energy delivered at any discrete point in time and will recognize revenue at an amount that reflects the consideration to which TVA is entitled for the energy delivered.

The amount of revenue is based on contractual prices approved by the TVA Board. Customers are invoiced monthly for power delivered as measured by meters located at the delivery points. The net transaction price is offset by certain credits available to customers that are known at the time of billing. Examples of credits include items such as economic development credits to promote growth in the Tennessee Valley and interruptible credits allowing TVA to reduce industrial customer usage in periods of peak demand to balance system demand. Payments are typically due within approximately one month of invoice issuance.

Other Revenue

Other revenue consists primarily of wheeling and network transmission charges, sales of excess steam that is a by-product of power production, delivery point charges for interconnection points between TVA and the customer, and certain other ancillary goods or services.

Disaggregated Revenue

During the three and six months ended March 31, 2020, revenues generated from TVA's electricity sales were $2.5 billion and $5.0 billion, respectively, and accounted for virtually all of TVA's revenues.

Note
(1) The amount for the three and six months ended March 31, 2020, is net of $36 million and $70 million, respectively, of wholesale bill credits to LPCs participating in the long-term Partnership Agreement.

TVA and LPCs continue to work together to meet the changing needs of consumers around the Tennessee Valley. At its August 2019 meeting, the TVA Board approved a 20-year Partnership Agreement option that better aligns the length of LPC contracts with TVA's long-term commitments. These agreements are automatically extended each year after their initial effective date, contingent upon certain circumstances, including agreement on flexibility options and limited rate increases going forward. Participating LPCs will receive benefits including a 3.1 percent wholesale bill credit in exchange for their long-term commitment, which enables TVA to recover its long-term financial commitments over a commensurate period. In addition, participating LPCs will have the option for flexible generation capacity up to approximately five percent of average total hourly energy sales over the prior five years. As of May 4, 2020, 139 LPCs had signed the 20-year Partnership Agreement with TVA.

Certain LPCs have five-year termination notices or a shorter period if any act of Congress, court decision, or regulatory change requires or permits that election.

TVA's two largest LPCs — Memphis Light, Gas and Water Division ("MLGW") and Nashville Electric Service ("NES") — have contracts with a five-year and a 20-year termination notice period, respectively. Sales to MLGW and NES each accounted for eight percent of TVA's total operating revenues during the six months ended March 31, 2020 and 2019.

Contract Balances

Contract assets represent an entity's right to consideration in exchange for goods and services that the entity has transferred to customers. TVA does not have any material contract assets at March 31, 2020.

Contract liabilities represent an entity's obligations to transfer goods or services to customers for which the entity has received consideration (or an amount of consideration is due) from the customers. These contract liabilities are primarily related to upfront consideration received prior to the satisfaction of the performance obligation. TVA does not have any material contract liabilities at March 31, 2020.

Economic Development Incentives. Under certain economic development programs, TVA offers incentives to existing and potential power customers in certain business sectors that make multi-year commitments to invest in the Tennessee Valley. TVA records those incentives as reductions of revenue. Incentives recorded as a reduction to revenue were $84 million and $89 million during the three months ended March 31, 2020 and 2019, respectively. Incentives recorded as a reduction to revenue were $160 million and $156 million during the six months ended March 31, 2020 and 2019, respectively. Incentives that have been approved but have not been paid are recorded in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. At March 31, 2020, and September 30, 2019, the outstanding unpaid incentives were $168 million and $157 million, respectively. These incentives may be subject to clawback provisions if the customers fail to meet certain program requirements. In April 2020, TVA established flexibility provisions to support the continued operations and recovery of participating customers impacted by the COVID-19 pandemic.

During the three months ended March 31, 2020, Other income (expense), net decreased $15 million as compared to the same period of the prior year, primarily driven by $12 million of unrealized losses on the SERP and DCP investments as a result of recent higher volatility in the financial markets associated with the COVID-19 pandemic.

During the six months ended March 31, 2020, Other income (expense), net decreased $27 million, primarily driven by $21 million of other income in 2019 related to a deposit liability received by TVA as a down payment on the sale of Bellefonte Nuclear Plant ("Bellefonte"). The purchaser, Nuclear Development, LLC, failed to fulfill the requirements of the sales contract with respect to obtaining NRC approval of the transfer of required nuclear licenses and payment of the remainder of the selling price before the November 30, 2018, closing date. See Note 20Contingencies and Legal Proceedings Legal Proceedings for a discussion of the lawsuit filed by Nuclear Development, LLC. Additionally, during the six months ended March 31, 2020, TVA experienced $10 million of unrealized losses on the SERP and DCP investments as a result of recent higher volatility in the financial markets associated with the COVID-19 pandemic.

18. Supplemental Cash Flow Information

Construction in progress and Nuclear fuel expenditures included in Accounts payable and accrued liabilities at March 31, 2020 and 2019, were $295 million and $281 million, respectively, and are excluded from the Statements of Consolidated Cash Flows for the six months ended March 31, 2020 and 2019, as non-cash investing activities.

19.  Benefit Plans

TVA sponsors a qualified defined benefit plan ("pension plan") that covers most of its full-time employees hired before July 1, 2014, a qualified defined contribution plan ("401(k) plan") that covers most of its full-time employees, two unfunded post-retirement health care plans that provide for non-vested contributions toward the cost of eligible retirees' medical coverage, other post-employment benefits, such as workers' compensation, and the SERP. The pension plan and the 401(k) plan are administered by a separate legal entity, the TVA Retirement System ("TVARS"), which is governed by its own board of directors.

TVA's minimum required pension plan contribution for 2020 is $300 million. TVA contributes $25 million per month to TVARS and as of March 31, 2020, had contributed $150 million. The remaining $150 million will be contributed by September 30, 2020. For the six months ended March 31, 2020, TVA also contributed $46 million to the 401(k) plan, $16 million (net of $3 million in rebates) to the other post-retirement plans, and $5 million to the SERP.

Financial markets have experienced higher volatility since September 30, 2019, due to the COVID-19 pandemic. The uncertainty as to the duration and severity of the COVID-19 pandemic has resulted in significantly lower market valuations for many investments. The impact of these events on TVA’s pension system is reflected in changes in the asset portfolio values from $8.0 billion at September 30, 2019, to $6.8 billion at March 31, 2020. TVA has not determined at this time whether additional contributions will be made to TVARS during 2020. Additionally, other post-retirement contributions related to the retiree health plans may be higher than previously assumed as a result of the COVID-19 pandemic increasing health care costs, but cannot be estimated at this time.

The ultimate impact of the COVID-19 pandemic on the pension plan and other post-retirement plans depends on factors beyond TVA’s knowledge or control, including the duration and severity of this outbreak, actions taken to contain its spread and mitigate its effects, and broader impacts of the COVID-19 pandemic on the country and region’s economy. Therefore, TVA currently cannot estimate the potential impact to the pension plan and other post-retirement plans at this time.

20.  Contingencies and Legal Proceedings

Contingencies

Nuclear Insurance.  Section 170 of the Atomic Energy Act, commonly known as the Price-Anderson Act, provides a layered framework of financial protection to compensate for liability claims of members of the public for personal injury and property damages arising from a nuclear incident in the U.S. This financial protection consists of two layers of coverage:

The primary level is private insurance underwritten by American Nuclear Insurers ("ANI") and provides public liability insurance coverage of $450 million for each nuclear power plant licensed to operate. If this amount is not sufficient to cover claims arising from a nuclear incident, the second level, Secondary Financial Protection, applies.

Within the Secondary Financial Protection level, the licensee of each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident of fault, up to a maximum of approximately $138 million per reactor per incident. With TVA's seven reactors, the maximum total contingent obligation per incident is $963 million. This retrospective premium is payable at a maximum rate currently set at approximately $20 million per year per incident per reactor. Currently, 97 reactors are participating in the Secondary Financial Protection program.

In the event that a nuclear incident results in public liability claims, the primary level provided by ANI combined with the Secondary Financial Protection should provide up to approximately $13.8 billion in coverage.


44


Federal law requires that each NRC power reactor licensee obtain property insurance from private sources to cover the cost of stabilizing and decontaminating a reactor and its station site after an accident. TVA carries property, decommissioning liability, and decontamination liability insurance from Nuclear Electric Insurance Limited ("NEIL") with limits up to $2.1 billion available for a loss at TVA's three sites. Some of this insurance may require the payment of retrospective premiums up to a maximum of approximately $139 million.

TVA purchases accidental outage (business interruption) insurance for TVA's nuclear sites from NEIL.  In the event that an accident covered by this policy takes a nuclear unit offline or keeps a nuclear unit offline, NEIL will pay TVA, after a waiting period, an indemnity (a set dollar amount per week) with a maximum indemnity of $490 million per unit.  This insurance policy may require the payment of retrospective premiums up to a maximum of approximately $46 million, but only to the extent the retrospective premium is deemed necessary by the NEIL Board of Directors to pay losses unable to be covered by NEIL's surplus.

Decommissioning Costs.  TVA recognizes legal obligations associated with the future retirement of certain tangible long-lived assets related primarily to nuclear generating plants, coal-fired generating plants, hydroelectric generating plants/dams, transmission structures, and other property-related assets. See Note 11Asset Retirement Obligations.

Nuclear Decommissioning.  Provision for decommissioning costs of nuclear generating units is based on options prescribed by the NRC procedures to dismantle and decontaminate the facilities to meet the NRC criteria for license termination. At March 31, 2020, $3.2 billion, representing the discounted value of future estimated decommissioning costs, was included in AROs.  The actual decommissioning costs may vary from the derived estimates because of, among other things, changes in current assumptions, such as the assumed dates of decommissioning, changes in regulatory requirements, changes in technology, and changes in the cost of labor, materials, and equipment.  Utilities that own and operate nuclear plants are required to use different procedures in calculating nuclear decommissioning costs under GAAP than those that are used in calculating nuclear decommissioning costs when reporting to the NRC.  The two sets of procedures produce different estimates for the costs of decommissioning primarily because of differences in the underlying assumptions. Decommissioning costs studies are updated for each of TVA's nuclear units at least every five years.

TVA maintains a NDT to provide funding for the ultimate decommissioning of its nuclear power plants.  See Note 15Fair Value MeasurementsInvestment Funds. TVA monitors the value of its NDT and believes that, over the long term and before cessation of nuclear plant operations and commencement of decommissioning activities, adequate funds from investments and additional contributions, if necessary, will be available to support decommissioning.  TVA's operating nuclear power units are licensed through various dates between 2033-2055, depending on the unit.  It may be possible to extend the operating life of some of the units with approval from the NRC. See Note 8Regulatory Assets and Liabilities and Note 11Asset Retirement Obligations.

Non-Nuclear Decommissioning.  The estimated future non-nuclear decommissioning ARO was $2.6 billion at March 31, 2020.  This decommissioning cost estimate involves estimating the amount and timing of future expenditures and making judgments concerning whether or not such costs are considered a legal obligation.  Estimating the amount and timing of future expenditures includes, among other things, making projections of the timing and duration of the asset retirement process and how costs will escalate with inflation.  The actual decommissioning costs may vary from the derived estimates because of changes in current assumptions, such as the assumed dates of decommissioning, changes in regulatory requirements, changes in technology, and changes in the cost of labor, materials, and equipment. TVA updates its underlying assumptions for non-nuclear decommissioning AROs at least every five years. However, material changes in underlying assumptions that impact the amount and timing of undiscounted cash flows are continuously monitored and incorporated into ARO balances in the period identified.

TVA maintains an ART to help fund the ultimate decommissioning of its non-nuclear power assets.  See Note 15Fair Value MeasurementsInvestment Funds. Estimates involved in determining if additional funding will be made to the ART include inflation rate, rate of return projections on the fund investments, and the planned use of other sources to fund decommissioning costs. See Note 8Regulatory Assets and Liabilities and Note 11Asset Retirement Obligations.

Environmental Matters. TVA's power generation activities, like those across the utility industry and in other industrial sectors, are subject to federal, state, and local environmental laws and regulations.  Major areas of regulation affecting TVA's activities include air quality control, water quality control, and management and disposal of solid and hazardous wastes.  In the future, regulations in all of these areas are expected to become more stringent.  Regulations are also expected to have a particular emphasis on climate change, renewable generation, and energy efficiency.

TVA has incurred, and expects to continue to incur, substantial capital and operating and maintenance costs to comply with evolving environmental requirements primarily associated with, but not limited to, the operation of TVA's coal-fired generating units.  Environmental requirements placed on the operation of TVA's coal-fired and other generating units will likely continue to become more restrictive over time. Litigation over emissions or discharges from coal-fired generating units is also occurring.  Failure to comply with environmental and safety laws can result in TVA being subject to enforcement actions, which can lead to the imposition of significant civil liability, including fines and penalties, criminal sanctions, and/or the shutting down of non-compliant facilities.

45


TVA estimates that compliance with existing and future Clean Air Act ("CAA") requirements (excluding greenhouse gas ("GHG") requirements) could lead to costs of $124 million from 2020 to 2024, which include existing controls capital projects and air operations and maintenance projects. TVA also estimates additional expenditures of approximately $1.1 billion from 2020 to 2024 relating to TVA's CCR conversion program, as well as expenditures of approximately $238 million from 2020 to 2024 relating to compliance with Clean Water Act requirements. Future costs could differ from these estimates if new environmental laws or regulations become applicable to TVA or the facilities it operates, or if existing environmental laws or regulations are revised or reinterpreted.  There could also be costs that cannot reasonably be predicted at this time, due to uncertainty of actions, that could increase these estimates.

Liability for releases and cleanup of hazardous substances is primarily regulated by the federal Comprehensive Environmental Response, Compensation, and Liability Act, and other federal and parallel state statutes.  In a manner similar to many other industries and power systems, TVA has generated or used hazardous substances over the years. TVA operations at some facilities have resulted in contamination that TVA is addressing.  At March 31, 2020, and September 30, 2019, TVA's estimated liability for cleanup and similar environmental work for those sites for which sufficient information is available to develop a cost estimate was approximately $12 million and $15 million, respectively, on a non-discounted basis, and was included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets.

Potential Liability Associated with Workers' Exposure to CCR Materials. In response to the 2008 ash spill at Kingston, TVA hired Jacobs Engineering Group, Inc. ("Jacobs") to oversee certain aspects of the cleanup. After the cleanup was completed, Jacobs was sued in the United States District Court for the Eastern District of Tennessee ("Eastern District") by employees of a contractor involved in the cleanup and family members of some of the employees. The plaintiffs alleged that Jacobs had failed to take or provide proper health precautions and misled workers about the health risks associated with exposure to coal fly ash, which is a CCR material. The plaintiffs alleged that exposure to the fly ash caused a variety of significant health issues and illnesses, including in some cases death. The case was split into two phases, with the first phase considering, among other issues, general causation and the second determining specific causation and damages. On November 7, 2018, a jury hearing the first phase returned a verdict in favor of the plaintiffs, including determinations that Jacobs failed to adhere to its contract with TVA or the Site Wide Safety and Health Plan in place; Jacobs failed to provide reasonable care to the plaintiffs; and Jacobs's failures were capable of causing a list of medical conditions, ranging from hypertension to cancer. On January 11, 2019, the Eastern District referred the parties to mediation. Mediation has concluded, but the parties did not resolve the matter. The litigation will now proceed to the second phase on the question of whether Jacobs's failures did in fact cause the plaintiffs' alleged injuries and damages.
 
On May 13, 2019, an additional group of contractor employees and family members filed suit against Jacobs in the Circuit Court for Roane County, Tennessee. These plaintiffs have raised similar claims to those being litigated in the case referenced above.

While TVA is not a party to either of these lawsuits, TVA could be contractually obligated to reimburse Jacobs for some amounts that Jacobs is required to pay. TVA will continue monitoring the litigation to determine whether these or similar cases could have broader implications for the utility industry. TVA does not expect any potential liability to have a material adverse impact on its results of operations or financial condition.

Legal Proceedings

From time to time, TVA is party to or otherwise involved in lawsuits, claims, proceedings, investigations, and other legal matters ("Legal Proceedings") that have arisen in the ordinary course of conducting TVA's activities, as a result of a catastrophic event or otherwise.  
 
General. At March 31, 2020, TVA had accrued $13 million of probable losses with respect to Legal Proceedings, which is included in Other long-term liabilities. No assurance can be given that TVA will not be subject to significant additional claims and liabilities.  If actual liabilities significantly exceed the estimates made, TVA's results of operations, liquidity, and financial condition could be materially adversely affected.
 
Environmental Agreements. In April 2011, TVA entered into two substantively similar agreements, one with the Environmental Protection Agency ("EPA") and the other with Alabama, Kentucky, North Carolina, Tennessee, and three environmental advocacy groups: the Sierra Club, the National Parks Conservation Association, and Our Children's Earth Foundation (collectively, the "Environmental Agreements"). Under the Environmental Agreements, TVA committed to, among other things, take actions regarding coal units that have been completed. TVA also agreed to invest $290 million in certain TVA environmental projects of which TVA had spent approximately $279 million as of March 31, 2020. In exchange for these commitments, most past claims against TVA based on alleged New Source Review and associated violations were waived and cannot be brought against TVA. Future claims, including those for sulfuric acid mist and GHG emissions, can still be brought against TVA.

The liabilities related to the Environmental Agreements are included in Accounts payable and accrued liabilities and Other long-term liabilities on the March 31, 2020, Consolidated Balance Sheets. In conjunction with the approval of the Environmental Agreements, the TVA Board determined that it was appropriate to record TVA's obligations under the

46


Environmental Agreements as regulatory assets, and they are included as such on the March 31, 2020, Consolidated Balance Sheets and will be recovered in rates in future periods.

Case Involving Kingston Fossil Plant. On May 7, 2019, Roane County and the Cities of Kingston and Harriman ("local governments") filed a lawsuit in the Circuit Court for Roane County, Tennessee, against TVA and Jacobs for monetary damages and unspecified injunctive relief relating to TVA's cleanup response to the 2008 ash spill at Kingston. The local governments allege that TVA and Jacobs failed to take proper measures to mitigate environmental and health risks during the cleanup response and misled the local governments and their citizens about health and environmental risks associated with exposure to coal fly ash. The local governments seek to recover monetary damages on behalf of their citizens for personal injury and property loss claims, damages for lost tax revenue, damages for increased emergency and medical response costs claims, punitive damages, and unspecified injunctive relief. On June 6, 2019, TVA removed the lawsuit to the Eastern District, and TVA and Jacobs filed separate motions to dismiss. Plaintiffs, in response, filed a response opposing both motions and a separate motion seeking leave to file a proposed amended class action complaint in which Roane County would serve as class representative for the municipalities and their citizens.

In December 2019, the federal court ruled that the local governments did not have standing to assert representative claims on behalf of their citizens and rejected their motion to proceed as a class action on behalf of their citizens because of the dissimilarity of the injuries allegedly suffered by the local governments (lost tax revenue) and the personal injuries and personal medical expenses allegedly suffered by the individuals. The court indicated, however, that the local governments may have legal standing to assert claims for their direct injuries (claims relating to municipally owned property) and directed the local governments to file an amended pleading in conformance with the court's order by January 16, 2020. The plaintiffs filed their amended complaint on January 15, 2020. Trial is set for April 2021.

Class Action Lawsuit Involving Kingston Fossil Plant. On November 7, 2019, a resident of Roane County, Tennessee, filed a proposed class action lawsuit against Jacobs and TVA in the Eastern District. The complaint alleges that the class representative and all other members of the proposed class were damaged as a result of the 2008 ash spill at Kingston and the resulting cleanup activities. The complaint alleges, among other things, that (1) TVA was negligent in its construction and operation of the Kingston CCR facility, (2) TVA and Jacobs failed to take proper measures to mitigate environmental and health risks during the cleanup response, and (3) TVA and Jacobs misled the community about health and environmental risks associated with exposure to coal fly ash. The complaint seeks monetary damages and injunctive relief in the form of an order requiring the defendants to establish a blood testing program and medical monitoring protocol and to remediate damage to the properties of the proposed class. On April 22, 2020, TVA moved to dismiss the complaint.

Case Involving Bull Run Fossil Plant. On February 5, 2020, two plaintiffs who reside near Bull Run filed suit against TVA in the Circuit Court for Anderson County, Tennessee, on behalf of themselves and their two minor children. The plaintiffs allege that they and their children were injured from direct exposures to CCR material originating from Bull Run and from second-hand exposures to coal ash through contact with a family member who worked at an undisclosed TVA facility. TVA
removed the case to the Eastern District on March 5, 2020, and the plaintiffs filed an amended complaint in federal court on
March 12, 2020.

Consent Decree Involving Colbert Fossil Plant. In May 2013, the Alabama Department of Environmental Management ("ADEM") and TVA entered into a consent decree concerning alleged violations of the Alabama Water Pollution Control Act. The consent decree required, among other things, that TVA continue remediation efforts TVA had begun prior to the suit being filed and stop using an unlined landfill after a lined landfill is approved and constructed. In August 2018, the parties agreed to amend the consent decree to deal with groundwater issues identified after TVA published groundwater monitoring reports in accordance with the EPA's CCR rule. The amended consent decree requires TVA to investigate the nature and extent of any groundwater contamination, develop and implement a remedy, provide semiannual status reports to ADEM, and remedy any seeps identified during inspections. TVA also paid $100,000 to Alabama under the amended consent decree. In accordance with the amended consent decree, TVA submitted to ADEM a Comprehensive Groundwater Investigation Report on May 17, 2019, and an Assessment of Corrective Measures on July 17, 2019. TVA is continuing to develop the groundwater remedy and submit reports to ADEM.

Case Involving Tennessee River Boat Accident. On July 23, 2015, plaintiffs filed suit in the United States District Court for the Northern District of Alabama ("Northern District"), seeking recovery for personal injuries sustained when the plaintiffs' boat struck a TVA transmission line which was being raised from the Tennessee River during a repair operation. The district court dismissed the case, finding that TVA's exercise of its discretion as a governmental entity in deciding how to carry out the operation barred any liability for negligence. In August 2017, the U.S. Court of Appeals for the Eleventh Circuit ("Eleventh Circuit") affirmed the decision. The plaintiffs petitioned the U.S. Supreme Court ("Supreme Court") for review of the decision, arguing that the provision of the TVA Act which allows suit to be brought against TVA does not allow TVA to claim immunity for discretionary actions. On April 29, 2019, the Supreme Court issued its opinion reversing the judgment of the Eleventh Circuit and remanding the case to the Eleventh Circuit. On July 17, 2019, the Eleventh Circuit remanded the case to the district court for further proceedings consistent with the Supreme Court's opinion. Trial is currently scheduled for February 16, 2021.

Case Involving Bellefonte Nuclear Plant. On November 30, 2018, Nuclear Development, LLC, filed suit against TVA in the Northern District. The plaintiff alleges that TVA breached its agreement to sell Bellefonte to the plaintiff. The plaintiff seeks,

47


among other things, (1) an injunction requiring TVA to maintain Bellefonte and the associated NRC permits until the case is concluded, (2) an order compelling TVA to complete the sale of Bellefonte to the plaintiff, and (3) if the court does not order TVA to complete the sale, monetary damages in excess of $30 million. On December 26, 2018, Nuclear Development, LLC, and TVA filed a joint stipulation with the court. Under the stipulation, Nuclear Development, LLC, withdrew its request for an expedited hearing on its injunction in exchange for TVA's agreement to continue to maintain Bellefonte in accordance with the NRC permits and to give Nuclear Development, LLC, and the court five days prior notice of any filing by TVA to terminate the permits or sell the site. TVA filed a motion to dismiss the case on February 4, 2019. On May 15, 2019, the court denied TVA's motion. The case is scheduled to be ready for trial by August 2020.

21. Subsequent Events

Interest Rate Reset on Certain Bonds

TVA announced on April 29, 2020, that the coupon rate on the TVA 1998 Series D bonds (CUSIP number 880591300) will be reset from the current rate of 3.55 percent to the new rate of 2.13 percent on June 1, 2020. Beneficial owners of the bonds have the option of requesting repayment at par value in conjunction with the rate reset. As a result, TVA could be required to repurchase up to $273 million of bonds on June 1, 2020.

LPC Deferral Program

As of May 4, 2020, $1 million of credit support has been approved under the Public Power Support and Stabilization Program.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(Dollars in millions except where noted)

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") explains the results of operations and general financial condition of the Tennessee Valley Authority ("TVA"). The MD&A should be read in conjunction with the accompanying unaudited consolidated financial statements and TVA's Annual Report on Form 10-K/A for the year ended September 30, 2019 (the "Annual Report").

Executive Overview

TVA's net income for the three and six months ended March 31, 2020, was $255 million and $447 million, respectively, as compared with net income of $241 million and $664 million for the same periods of the prior year. As is often the case for electric utilities, weather is a primary driver of TVA's sales and revenue. Despite record-setting heat experienced during October 2019 and record-setting cold during November 2019, TVA's service territory experienced overall milder weather during the six months ended March 31, 2020. This overall milder weather drove lower energy sales. Similarly, revenue from sales of electricity decreased $372 million for the six months ended March 31, 2020, as compared to the same period of the prior year.
Depreciation and amortization expense increased $230 million for the six months ended March 31, 2020, as compared to the same period of the prior year. This increase was primarily due to accelerated depreciation from the retirement decisions at Bull Run Fossil Plant ("Bull Run") and Paradise Fossil Plant ("Paradise"). Fuel and purchased power expense decreased $171 million for the six months ended March 31, 2020, as compared to the same period of the prior year. This decrease was primarily due to lower energy sales, as well as lower effective fuel and purchased power rates and availability of lower cost TVA-owned generation. Operating and maintenance expense decreased $212 million for the six months ended March 31, 2020, as compared to the same period of the prior year. This was primarily driven by prior year recovery of the regulatory asset for environmental cleanup costs related to the Kingston ash spill.

In March 2020, the World Health Organization declared the outbreak of Coronavirus Disease 2019 ("COVID-19") a pandemic, which continues to spread throughout the United States. TVA is coordinating with local power company customers (“LPCs”) and partners to understand the impact to its service territory. During March 2020, the TVA Board approved the Public Power Support and Stabilization Program, offering up to $1.0 billion of credit support to provide temporary financial relief for its LPCs in the form of deferred payments of power bills under certain circumstances. Operations and delivery of energy to customers have not been materially impacted at this time. TVA continues to monitor the situation and will adjust its response as necessary to ensure reliable service while protecting the safety and health of its workforce and sustaining business operations.
The Tennessee Valley experienced significant rainfall during the second quarter of 2020, setting records for the wettest second quarter and the third wettest February in TVA’s history. Despite significant rainfall, runoff, and flooding during the period, TVA continued to generate low-cost hydroelectric power while meeting its river system commitments, including flood mitigation which prevented approximately $1.0 billion in damages across the Tennessee Valley.

TVA continues to maintain 99.999 percent reliability in delivering energy to its customers despite experiencing record-setting weather. TVA's reliability and economic development efforts continue to attract and encourage the expansion of business

48


and industries in the Tennessee Valley, with over $6.1 billion in investments and more than 51,500 jobs created or retained through the second quarter of 2020.

Sales of electricity decreased approximately two percent for the three months ended March 31, 2020, as compared to the same period of the prior year, primarily due to decreased sales volume for LPCs driven predominantly by a 13 percent decrease in total degree days. The Tennessee Valley's weather has averaged warmer than normal temperatures over this period, thereby reducing energy sales. Partially offsetting the decreased sales volume for LPCs, sales to industries directly served increased as TVA began supplying power to new customers in the data processing, hosting, and related services sector. TVA experienced a decrease in sales of electricity for the three months ended March 31, 2020 associated with the COVID-19 pandemic, and expects reductions in sales to continue for the remainder of 2020.

Sales of electricity decreased approximately three percent for the six months ended March 31, 2020, as compared to the same period of the prior year, primarily due to decreased sales volume for LPCs driven predominantly by an 11 percent decrease in total degree days. During October 2019, TVA recorded its third largest peak power demand for the month of October at 28,353 megawatts with a system average temperature of 97 degrees Fahrenheit. During November 2019, TVA recorded its highest peak power demand for the month of November at 27,722 megawatts with a system average temperature of 20 degrees Fahrenheit. Despite record-setting heat experienced during October 2019 and record-setting cold during November 2019, TVA's service territory experienced overall milder weather during the six months ended March 31, 2020.

TVA's current rate structure provides pricing signals intended to signal higher cost periods to serve its customers and capture a portion of TVA's fixed costs in fixed charges.  The structure includes three base revenue components: time of use demand charges, time of use energy charges, and a grid access charge ("GAC").  The demand charges are based upon the customer's peak monthly usage and increase as the peak increases. The energy charges are based on time differentiated kWh used by the customer.  Both of these components can be significantly impacted by weather. The GAC captures a portion of fixed costs and will be offset by a corresponding reduction to the energy rates.  The GAC also reduces the impact of weather variability to the overall rate structure.

Additionally, at its August 2019 meeting, the TVA Board approved a 20-year Partnership Agreement option that better aligns the length of LPC contracts with TVA's long-term commitments. Participating LPCs will receive benefits including a 3.1 percent wholesale bill credit in exchange for their long-term commitment, which enables TVA to recover its long-term financial commitments over a commensurate period. As of May 4, 2020, 139 LPCs had signed the 20-year Partnership Agreement with TVA.

In addition to base revenues, the rate structure also includes a separate fuel rate that includes the costs of natural gas, fuel oil, purchased power, coal, emission allowances, nuclear fuel, and other fuel-related commodities; realized gains and losses on derivatives purchased to hedge the costs of such commodities; and payments to states and counties in lieu of taxes ("tax equivalents") associated with the fuel cost adjustments.

The changes in revenue components for the three and six months ended March 31, 2020, compared to the three and six months ended March 31, 2019, are summarized below:

Operating revenues decreased $229 million for the three months ended March 31, 2020, as compared to the same period of the prior year, primarily due to a $127 million decrease in base revenue and a $97 million decrease in fuel cost recovery revenue. The $127 million decrease in base revenue was driven by a decrease of $43 million attributable to lower effective rates and a decrease of $84 million attributable to lower sales volume. Lower energy sales resulted primarily from milder weather for the Tennessee Valley service area during the three months ended March 31, 2020. The $97 million decrease in fuel cost recovery revenue was driven by an $81 million decrease attributable to lower fuel rates and a $16 million decrease attributable to lower energy sales during the quarter. TVA has experienced a decrease in base revenue for the three months ended March 31, 2020 associated with the COVID-19 pandemic and expects reductions in revenue to continue for the remainder of 2020.
Operating revenues decreased $376 million for the six months ended March 31, 2020, as compared to the same period of the prior year, primarily due to a $193 million decrease in fuel cost recovery revenue and a $180 million decrease in base revenue. The $193 million decrease in fuel cost recovery revenue was driven by a $150 million decrease attributable to lower fuel rates and a $43 million decrease attributable to lower energy sales. Lower energy sales resulted primarily from overall milder weather for the Tennessee Valley service area during the six months ended March 31, 2020, despite record-setting heat in October 2019 and record-setting cold in November 2019. The $180 million decrease in base revenue was driven by a decrease of $84 million attributable to lower effective rates and a decrease of $96 million attributable to lower sales volume during the quarter.

chart-fd8b63958a0852d9b58.jpg
Fuel
Fuel expense decreased $72 million for the three months ended March 31, 2020, as compared to the same period of the prior year. This decrease was primarily due to lower effective fuel rates of $64 million, resulting from lower natural gas prices. A decrease in total degree days reduced demand for power generation, contributing to a reduction in volume of $8 million.
chart-dcc6363a2cdc5cb7871.jpg
Purchased Power
Purchased power expense decreased $3 million for the three months ended March 31, 2020, as compared to the same period of the prior year. This was primarily due to a decrease in volume of $2 million and a decrease of $1 million in fuel rate recovery.

chart-5e31ea98692450cea54.jpg
Operating and Maintenance
Operating and maintenance expense decreased $156 million for the three months ended March 31, 2020, as compared to the same period of the prior year. This was primarily driven by a decrease of $130 million of project write-offs and materials and supplies inventory reserves and write-offs related to the retirement of Bull Run and Paradise. Additionally, $65 million of prior year recovery of the regulatory asset for Environmental cleanup costs related to the Kingston ash spill contributed to the decrease. Partially offsetting these decreases was an increase in planned nuclear outage days which increased the expense by $16 million and $33 million of increased payroll and benefit costs due to labor escalation for cost of living increases.
chart-ae113ace43795866885.jpg
Depreciation and Amortization
Depreciation and amortization expense decreased $9 million for the three months ended March 31, 2020, as compared to the same period of the prior year.  This was primarily driven by a net decrease in depreciation expense of $20 million related to the decision in the second quarter of 2019 to accelerate the retirements of Bull Run and Paradise. Partially offsetting this decrease was a $6 million increase in amortization expense of non-nuclear decommissioning costs recovered in rates. The remaining variance is primarily due to depreciation of additions to Completed plant.
chart-35ddda418d535e26913.jpg
Tax Equivalents
Tax equivalents expense decreased $4 million for the three months ended March 31, 2020, as compared to the same period of the prior year. The change is primarily driven by a decrease in the tax equivalents collected in the fuel rate recovery.

chart-2ba920c4f2c566f5440.jpg
Fuel
Fuel expense decreased $90 million for the six months ended March 31, 2020, as compared to the same period of the prior year. Lower effective fuel rates contributed $121 million to the decrease, resulting from lower natural gas prices and increased availability of nuclear fuel. Partially offsetting this decrease was an increase of $31 million driven by variances in fuel rate recovery.
chart-7012bdecd7a9889181e.jpg
Purchased Power
Purchased power expense decreased $81 million for the six months ended March 31, 2020, as compared to the same period of the prior year. This was primarily due to a decrease in volume of $96 million as a result of milder weather and more availability of lower cost TVA owned generation in the current year. Lower effective purchased power rates contributed an additional $4 million to the decrease. Partially offsetting these decreases was an increase of $19 million in fuel rate recovery.

Operating and Maintenance
Operating and maintenance expense decreased $212 million for the six months ended March 31, 2020, as compared to the same period of the prior year. This was primarily driven by a decrease of $126 million of project write-offs and materials and supplies inventory reserves and write-offs related to the retirement of Bull Run and Paradise. Additionally, $130 million of recovery in the prior year of the regulatory asset for Environmental cleanup costs related to the Kingston ash spill contributed to the decrease. Partially offsetting these decreases was an increase of $15 million related to TVA's capital spare program and $49 million of increased payroll and benefit costs due to labor escalation for cost of living increases.

(4) There were no Allowance for Funds Used During Construction amounts for the periods shown above.

Total interest expense decreased $11 million for the three months ended March 31, 2020, as compared to the same period of the prior year.  This was driven by a decrease of $14 million in interest expense due primarily to lower average debt balances.

Total interest expense decreased $26 million for the six months ended March 31, 2020, as compared to the same period of the prior year.  This was driven by a decrease of $23 million in interest expense due primarily to lower average debt balances.

Other Income (Expense), Net. During the three months ended March 31, 2020, Other income (expense), net decreased $15 million as compared to the same period of the prior year, primarily driven by $12 million of unrealized losses on the SERP and DCP investments as a result of recent higher volatility in the financial markets associated with the COVID-19 pandemic.

During the six months ended March 31, 2020, Other income (expense), net decreased $27 million, primarily driven by $21 million of other income in 2019 related to a deposit liability received by TVA as a down payment on the sale of Bellefonte Nuclear Plant ("Bellefonte"). The purchaser, Nuclear Development, LLC, failed to fulfill the requirements of the sales contract with respect to obtaining Nuclear Regulatory Commission ("NRC") approval of the transfer of required nuclear licenses and payment of the remainder of the selling price before the November 30, 2018, closing date. See Note 20Contingencies and Legal Proceedings Legal Proceedings for a discussion of the lawsuit filed by Nuclear Development, LLC. Additionally, during the six months ended March 31, 2020, TVA experienced $10 million of unrealized losses on the SERP and DCP investments as a result of recent higher volatility in the financial markets associated with the COVID-19 pandemic.

Liquidity and Capital Resources

Sources of Liquidity

TVA depends on various sources of liquidity to meet cash needs and contingencies. TVA's primary sources of liquidity are cash from operations and proceeds from the issuance of short-term debt in the form of discount notes, along with periodic issuances of long-term debt. TVA's balance of short-term debt typically changes frequently as TVA issues discount notes to meet short-term cash needs and pay scheduled maturities of discount notes and long-term debt. The periodic amounts of short-term debt issued are determined by near-term expectations for cash receipts, cash expenditures, and funding needs, while seeking to maintain a target range of cash and cash equivalents on hand.

In addition to cash from operations and proceeds from the issuance of short-term and long-term debt, TVA's sources of liquidity include a $150 million credit facility with the United States Department of the Treasury ("U.S. Treasury"), four long-term revolving credit facilities totaling $2.7 billion, and proceeds from other financings. See Note 12Debt and Other Obligations
Credit Facility Agreements. Other financing arrangements may include sales of receivables, loans, and other assets.

The TVA Act authorizes TVA to issue bonds, notes, or other evidences of indebtedness (collectively, "Bonds") in an amount not to exceed $30.0 billion outstanding at any time. Bonds outstanding, excluding unamortized discounts and premiums and net exchange gains from foreign currency transactions, at March 31, 2020, were $21.1 billion (including current maturities). The balance of Bonds outstanding directly affects TVA's capacity to meet operational liquidity needs and to strategically use Bonds to fund certain capital investments as management and the TVA Board may deem desirable.  Other options for financing not subject to the limit on Bonds, including lease financings (see Lease Financings below, Note 6 Leases, and Note 9Variable Interest Entities), could provide supplementary funding if needed. Currently, TVA believes that it has adequate capability to fund its ongoing operational liquidity needs and make planned capital investments over the next decade through a combination of Bonds, additional power revenues through power rate increases, cost reductions, or other ways. See Lease Financings below, Note 9Variable Interest Entities, and Note 12Debt and Other Obligations for additional information.

TVA may from time to time seek to retire or purchase its outstanding debt through cash purchases and/or exchanges for securities, in open market purchases, privately negotiated transactions, or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, TVA's liquidity requirements, contractual restrictions, and other factors. The amounts involved may be material.

Due to recent higher volatility in the financial markets associated with the COVID-19 pandemic, TVA increased its target balance of Cash and cash equivalents in March 2020 by $500 million through discount note issuances. TVA has maintained continued debt market access since the outbreak of the pandemic. TVA also successfully funded the maturity of $1.0 billion of power bonds in March 2020 with cash from operations and proceeds from the issuance of discount notes. TVA's next material power bond maturity of $1.5 billion is in February 2021.

In response to the COVID-19 pandemic, the TVA Board approved the Public Power Support and Stabilization Program, which includes alternative wholesale payment arrangements for LPCs, on March 25, 2020. Under these arrangements, TVA is offering up to $1.0 billion of credit support to LPCs, who demonstrate the need for temporary financial relief, through the deferral of a portion of LPCs' wholesale power payments owed to TVA. The program requires LPCs to apply for the deferral, which is subject to approval by TVA. If approved, TVA will establish a repayment schedule based on the LPC's need, not to exceed two years, and an initial repayment date will be approved by TVA no later than December 31, 2020. These actions continue to show TVA's commitment to support the financial integrity of LPCs during challenging economic conditions caused by the COVID-19 pandemic.

Debt Securities.  TVA's Bonds are not obligations of the U.S., and the U.S. does not guarantee the payments of principal or interest on Bonds. TVA's Bonds consist of power bonds and discount notes. Power bonds have maturities of between one and 50 years. At March 31, 2020, the average maturity of long-term power bonds was 16.40 years, and the average interest rate was 4.78 percent. Discount notes have maturities of less than one year. Power bonds and discount notes have a first priority and equal claim of payment out of net power proceeds. Net power proceeds are defined as the remainder of TVA's gross power revenues after deducting the costs of operating, maintaining, and administering its power properties and payments to states and counties in lieu of taxes, but before deducting depreciation accruals or other charges representing the amortization of capital expenditures, plus the net proceeds from the sale or other disposition of any power facility or interest therein. In addition to power bonds and discount notes, TVA had long-term debt associated with certain VIEs outstanding at March 31, 2020. TVA also had secured notes outstanding at March 31, 2020 that were assumed in a prior year asset acquisition.

Lease Financings. TVA has entered into certain leasing transactions with special purpose entities ("SPEs") to obtain third-party financing for its facilities. These SPEs are sometimes identified as VIEs of which TVA is determined to be the primary beneficiary. TVA is required to account for these VIEs on a consolidated basis. See Note 9Variable Interest Entities and Note 12 Debt and Other Obligations for information about TVA's lease financing activities. During 2017 and 2016, TVA acquired 100 percent of the equity interests in certain SPEs created for the purpose of facilitating lease financing. TVA may seek to enter into similar arrangements in the future. In March 2019, TVA made final rent payments under lease/leaseback transactions involving eight CTs, and in July 2019, these transactions were terminated.

Summary Cash Flows

A major source of TVA's liquidity is operating cash flows resulting from the generation and sale of electricity. Cash, cash equivalents, and restricted cash were $858 million at March 31, 2020, compared to $323 million at March 31, 2019. A summary of cash flow components for the six months ended March 31, 2020 and 2019, follows:

    Cash provided by (used in):                         chart-a17ee7ea923f5a6f8c2.jpgchart-b466ed1f18475b2d8ff.jpgchart-92afcabc990054d196a.jpg
Operating Activities. TVA's cash flows from operations are primarily driven by sales of electricity, fuel expense, and operating and maintenance expense. The timing and level of cash flows from operations can be affected by the weather, changes in working capital, commodity price fluctuations, outages, and other project expenses.

Net cash flows provided by operating activities increased $123 million for the six months ended March 31, 2020, as compared to the same period of the prior year. The increase is due to lower fuel and purchased power payments as a result of milder weather and more availability of lower cost TVA owned generation in the current year. This increase is partially offset by lower revenue collections due to decreased revenue from sales of electricity, as a result of overall milder weather and long-term partnership credits for LPCs.

Investing Activities. The majority of TVA's investing cash flows are due to investments to acquire, upgrade, or maintain generating and transmission assets, including environmental projects and the purchase of nuclear fuel.
    
Net cash flows used in investing activities decreased $30 million for the six months ended March 31, 2020, as compared to the same period of the prior year driven by the completion of the Browns Ferry extended power uprate in the prior year.  This decrease was partially offset by an increase in expenditures for the Boone Dam and Pickwick South Embankment Remediation projects and increases in nuclear fuel expenditures.  Nuclear fuel expenditures vary depending on the number of outages and the prices and timing of purchases of uranium and enrichment services. 

58


Financing Activities. TVA's cash flows provided by or used in financing activities are primarily driven by the timing and level of cash flows provided by operating activities, cash flows used in investing activities, and net issuance and redemption of debt instruments to maintain a strategic balance of cash on hand.

Net cash used in financing activities decreased $382 million for the six months ended March 31, 2020, as compared to the same period of the prior year driven by the increase in discount note issuances to fund power bond maturities and to increase the Cash and cash equivalents target balance by $500 million due to higher recent volatility in the financial markets associated with the COVID-19 pandemic.

As a result of certain commercial and industrial customers curtailing operations in response to the COVID-19 pandemic, TVA experienced decreases in base revenue for the three months ended March 31, 2020. TVA currently anticipates base revenue to be lower than plan by between $300 million and $500 million for the remainder of 2020. Due to these expected reductions in revenue associated with the COVID-19 pandemic, TVA is implementing various cost savings initiatives such as deferring certain capital project expenses, prioritizing certain capital projects, and decreasing discretionary spending. TVA may also experience an increase in interest cost, fuel cost, and other additional operating costs. The ultimate impact of the COVID-19 pandemic on TVA's financial condition depends on factors beyond TVA’s knowledge or control, including the duration and severity of this outbreak, actions taken to contain its spread and mitigate its effects, and broader impacts of the COVID-19 pandemic on the country and region’s economy.

Contractual Obligations
TVA has obligations and commitments to make future payments under certain contracts. During the six months ended March 31, 2020, there were no material changes in TVA's contractual obligations outside of the ordinary course of business. TVA's contractual obligations are discussed in Item 7, Management's Discussion and Analysis of Financial Condition and Results of OperationsLiquidity and Capital Resources and Note 21Benefit Plans of the Notes to Consolidated Financial Statements in the Annual Report.

Key Initiatives and Challenges

Coronavirus Pandemic

In December 2019, a novel strain of coronavirus was reported in China. As this strain continued to spread across the globe, the World Health Organization declared the outbreak of the 2019 novel coronavirus a pandemic on March 11, 2020. TVA has performed risk analyses across the company to determine potential impacts and monitor performance throughout the situation. TVA has implemented a company-wide pandemic plan to address specific aspects of the COVID-19 pandemic, including limiting business related travel and encouraging working remotely when possible. TVA continues to implement strong physical and cybersecurity measures to ensure that systems remain functional to keep employees, customers, and communities safe and enable TVA to continue achieving its mission to serve the people of the Valley.

Further, in response to enhanced public health guidance from federal and state authorities, TVA has closed certain recreation areas including water recreation facilities, campgrounds, visitor centers, and trails to slow the spread of the virus. These closures will continue indefinitely until it is safe to resume full operations.

In addition to measures to protect its workforce, stakeholders, and critical operations, TVA is actively monitoring generation, transmission, and distribution functions. Operations and delivery of energy to customers have not been materially impacted. Certain commercial and industrial customers have curtailed operations in response to COVID-19 pandemic social distancing standards and economic uncertainty. Therefore, TVA is experiencing decreased energy demand in those sectors. Due to expected reductions in TVA's revenue for the remainder of 2020 associated with this decreased energy demand, TVA is implementing various cost savings initiatives such as deferring certain capital project expenses, prioritizing certain capital projects, and decreasing discretionary spending.

TVA has developed initial internal forecasts based on a range of external data sources in an effort to estimate the impact of the COVID-19 pandemic on its operations. The model inputs include external projections of gross domestic and gross regional products, unemployment rates, pandemic duration, business and social responses to the disease, and other factors to forecast the impact on TVA energy demand and revenues. Based on initial forecasts of early data, TVA anticipates base revenue to be lower than plan by between $300 million and $500 million for the remainder of 2020. However, estimates of each of these factors are constantly changing as the pandemic situation evolves and projections are refined. As such, TVA’s estimate of the impact to its financial position, results of operations, and cash flows will be evolving over the remainder of the year and could differ materially from TVA's initial forecasts based on early data.

TVA is also assessing potential supplier performance risks, including procurement of fuel, parts, and services. If suppliers are unable to perform under TVA's existing contracts or if TVA is unable to obtain similar services from other vendors, TVA could experience delays, disruptions, additional costs, or other operational outcomes that may impact generation, maintenance, and capital programs. At this time, TVA has not identified any specific issues related to supplier performance in

59


the near term. Certain planned outages at generating facilities and construction projects may be delayed based on availability of contractors and supplies.

The COVID-19 pandemic has created economic uncertainty for TVA’s LPCs and the communities they serve. To support LPCs and strengthen the public power response to the COVID-19 pandemic, TVA announced initiatives to enable and support LPCs in taking timely, local action. TVA first provided regulatory flexibility for LPCs to halt disconnection of services and respond to the local needs of their customers and communities. On March 25, 2020, the TVA Board approved the Public Power Support and Stabilization Program, which includes alternative wholesale payment arrangements for LPCs. TVA is offering up to $1.0 billion of credit support to LPCs who demonstrate the need for temporary financial relief, through the deferral of a portion of LPCs' wholesale power payments owed to TVA.  The program requires LPCs to apply for the deferral, which is subject to approval by TVA.  If approved, TVA will establish a repayment schedule based on the LPC’s need, not to exceed two years, and an initial repayment date will be approved by TVA no later than December 31, 2020.  As of May 4, 2020, $1 million of credit support has been approved under the Public Power Support and Stabilization Program. Additionally, TVA created the Back-to-Business credit program that will enable TVA and LPCs to provide relief to certain large customers affected by the COVID-19 pandemic by providing certain credits when returning to operations. TVA is also partnering with LPCs by providing $2 million in matching funds to support local initiatives that address hardships created by the COVID-19 pandemic. These actions continue to show TVA's commitment to support the financial integrity of LPCs along with communities and customers across the Valley during these challenging economic conditions caused by the COVID-19 pandemic.

The COVID-19 pandemic is a rapidly evolving situation that may lead to extended disruption of economic activity and an adverse impact on TVA's results of operations. TVA is closely monitoring developments and will continue adjusting its response as necessary to ensure reliable service while protecting the safety and health of its workforce. Despite TVA’s efforts to manage the effects of the COVID-19 pandemic, their ultimate impact also depends on factors beyond TVA’s knowledge or control, including the duration and severity of this outbreak, actions taken to contain its spread and mitigate its effects, and broader impacts of the COVID-19 pandemic on the country and region’s economy.

Distributed Energy Resources

Consumer desire for energy choice, among other things, is driving the expectation for flexible options in the electric industry. TVA and LPCs are working together to leverage the strengths of the Tennessee Valley public power model to provide distributed energy solutions that are economical, sustainable, and flexible. TVA will focus on the safety and reliability impacts of these resources as they are interconnected to the grid and will ensure that the pricing of electricity remains as low as feasible. Additional regulatory considerations and analysis may be required as the DER market, technologies, and programs evolve. TVA is working to develop pricing and regulatory structures with a deliberate and thoughtful analysis of each current and future program offering. This requires strong partnerships with LPCs to give customers choices and provide end-use consumers the flexibility they desire.

In May 2017, the TVA Board authorized up to $300 million to be spent over the next 10 years, subject to annual budget availability and necessary environmental reviews, to build an enhanced fiber optic network that will better connect TVA's operational assets. Fiber is a vital part of TVA's modern communication infrastructure. The new fiber optic lines will improve the reliability and resiliency of the generation and transmission system while enabling the system to better accommodate DER as they enter the market. As of March 31, 2020, TVA had spent $102 million on installation of the fiber optic lines and expects to spend an additional $198 million to complete the project.
    
Changing Customer Preferences

As more consumers and businesses are demanding cleaner energy, the utility industry is evolving to meet those needs. As TVA also evolves, it will see impacts to the way it does business through the pricing of products, transmission of energy, and development of new products and services for its customers in support of changing customer preferences and its economic development efforts. End-use customers are becoming more technologically sophisticated and want greater control over their energy usage. Many companies are focusing more on sustainability and requiring more energy efficiency as well as cleaner, more renewable energy options. The continuing challenge for TVA and others is finding ways to meet the needs and preferences of customers while successfully developing flexible pricing models to accommodate the evolving markets.

Low-Income Energy Efficiency Program. Through the Home Uplift Program, TVA is partnering with LPCs, state and local governments, non-profit agencies, energy efficiency advocates, and the Tennessee Valley Public Power Association to complete home evaluations and make high-impact home energy upgrades for qualifying homeowners. In addition, TVA and LPCs conduct workshops to educate homeowners about low and no-cost energy efficiency upgrades that improve their quality of life.

Renewable Power Purchase Agreements.  In order to meet customer preferences and requirements for cleaner energy, TVA entered into certain power purchase agreements ("PPAs") with renewable resource providers during 2019.  These agreements are the latest to stem from TVA's 2017 request for proposals for renewable energy.  In 2019, TVA signed four solar PPAs for 674 megawatts ("MW") of solar generation at sites in Tennessee and Alabama.  These four solar projects are expected to come online in 2021.  During 2020, as a result of TVA’s 2019 request for proposals for renewable energy, TVA signed six

60


additional PPAs for 661 MW of solar generation with 50 MW of battery storage expected to come online in 2022. TVA will procure the renewable energy and sell the resulting Renewable Energy Certificates to specific customers, allowing TVA to increase its renewable energy portfolio without additional costs to other Valley customers.  These agreements help to align the core values of TVA and the public power model with the desire of TVA's customers for renewable energy.

Further, TVA issued another request for proposal during the second quarter of 2020 for up to 200 MW of new renewable energy. The ultimate volume contracted will align to TVA customers' demand for renewable energy, allowing TVA to increase its renewable energy portfolio without additional costs to other Valley customers. TVA anticipates making selections during the fourth quarter of 2020.

Renewable Power Solutions. During its February 2019 meeting, the TVA Board approved new renewable power solutions, including a utility-scale option and a mid-scale option, that better equip TVA and LPCs with the flexibility to meet changing end-use customer needs. The utility-scale option, which aggregates demand through a competitive procurement process, is implemented by a renewable investment agreement through TVA's Green Invest Program. TVA may also construct its own renewable facilities to meet these needs. The mid-scale option, also known as the Flexibility Research Project, is a joint project with LPCs to enable solutions for situations where the end-use consumer needs onsite renewable or distributed generation. This project will allow TVA to gain market knowledge and operational insights.

Natural Resource Plan

TVA is updating its Natural Resource Plan ("NRP"), which was completed in 2011 to guide TVA's management of the public lands and waters within its seven-state service area. TVA remains committed to a balanced management approach and is considering changes to the NRP that include objectives and programs for each focus area and a flexible approach for long-term planning. These changes align with TVA's mission and will help TVA be better equipped to prioritize funding plans and create efficiencies in business planning and stewardship project implementation. During 2019, TVA hosted public meetings around the Valley and released the draft NRP and the associated Supplemental Environmental Impact Statement ("SEIS") for public review and comment. TVA published the final SEIS and 2020 NRP in February 2020, and intends to present them to the TVA Board at its May 2020 meeting for approval.

Strategic Financial Plan

In 2019, the TVA Board approved an annual budget that reflects the first year of a new Strategic Financial Plan. The Strategic Financial Plan, which extends from 2020 through 2030, is flexible in aligning customer preferences and TVA's mission while at the same time establishing a long-term forecast of financial results. Key focus areas of the Strategic Financial Plan include maintaining rates as low as feasible, establishing better alignment between the length of LPC contracts and TVA's long-term commitments, stabilizing debt in an $18.0 billion to $20.0 billion range, assuming 100 percent long-term partner participation, maintaining a cash balance of $300 million, and pursuing operational efficiencies. As TVA executes the plan, key assumptions and performance may change estimated debt and cash balances. Due to recent higher volatility in the financial markets associated with the COVID-19 pandemic, TVA increased its target balance of Cash and cash equivalents in March 2020 by $500 million through short-term discount note issuances.

Generation Resources

Extreme Flooding Preparedness. Updates to the TVA analytical hydrology model completed in 2009 indicated that under "probable maximum flood" conditions, some of TVA's dams might not have been capable of regulating the higher flood waters.  A "probable maximum flood" is an extremely unlikely event; however, TVA is obligated to provide protection for its nuclear plants against such events.  As a result, TVA installed a series of modifications at four dams.

Since 2009, TVA has performed further hydrology modeling of portions of the TVA watershed using updated modeling tools. The revised hydrology models were reviewed and approved by the NRC for Watts Bar Units 1 and 2. However, TVA identified an error in the modeling that will require the models for Watts Bar Units 1 and 2 to be resubmitted. TVA plans to resubmit models for Watts Bar Units 1 and 2 during the third quarter of 2020.  In addition, TVA submitted models for Sequoyah Nuclear Plant ("Sequoyah") Units 1 and 2 on January 14, 2020.  TVA will subsequently address conditions at Browns Ferry as needed.  TVA is deferring the decision on the need for additional modifications until after the modeling work is complete.
As of March 31, 2020, TVA had spent $153 million on the modifications and improvements related to extreme flooding preparedness and expects to spend up to an additional $27 million to complete the modifications.

NRC Seismic Assessments. In 2014, the NRC notified licensees of nuclear power reactors in the central and eastern U.S. of the results of seismic hazard screening and prioritization evaluations performed by unit owners and reviewed by the NRC staff. Because the seismic hazards for Browns Ferry, Sequoyah, and Watts Bar had increases in seismic parameters beyond the technical information available when the plants were designed and licensed, TVA must conduct seismic risk evaluations for these plants. TVA completed the risk evaluation for Watts Bar and submitted it to the NRC in 2017; the evaluation concluded that no additional actions were required. The NRC completed its review of the Watts Bar evaluation in 2018 and concluded that no further response or regulatory actions were required. The evaluation for Sequoyah was submitted on October 18, 2019 and

61


the evaluation for Browns Ferry was submitted on December 17, 2019. TVA anticipates the NRC will complete its review this year.
Mitigation of Beyond-Design-Basis Events.  NRC rulemaking has been developed to codify the requirements promulgated by orders related to beyond-design-basis flooding and seismic events discussed above. The NRC Commissioners approved the final rule in 2019.  TVA plans to implement requirements for Sequoyah and Watts Bar by 2022 and for Browns Ferry by 2023.  A gap review of the revised rule has been performed, and no new gaps to compliance were identified.  Actions to complete flood and seismic assessments are still ongoing. See Extreme Flooding Preparedness and NRC Seismic Assessments above.
Work Environment at Nuclear Plants. In March 2016, the NRC issued a Chilling Effect Letter ("CEL") to TVA regarding work environment concerns identified at Watts Bar. In the mid-cycle assessment letter issued in June 2018, the NRC issued a Cross Cutting Issue in safety conscious work environment ("CCI") and outlined the closure criteria for both the CEL and CCI.  In October 2019, TVA informed the NRC of its CEL and CCI closure criteria readiness, and the NRC completed its inspection, resulting in no findings with progress noted as documented in its December 2019 inspection report.  In March 2020, the NRC issued its Annual Assessment Letter for Watts Bar noting TVA’s progress in addressing the CEL and CCI while stating that the NRC continues to monitor TVA’s activities as they deliberate on the appropriate time to close the CEL and CCI.

Apparent Violations of NRC Regulations. On March 2, 2020, the NRC issued a letter to TVA identifying four apparent violations of NRC regulations that prohibit licensees from retaliating against employees for their having raised protected nuclear safety concerns. On March 9, 2020, the NRC issued a letter to TVA identifying twelve apparent violations of NRC regulations: six relating to operational activities and six relating to NRC regulations governing the completeness and accuracy of information. TVA is evaluating these matters in accordance with its processes and will have an opportunity to discuss these matters with the NRC at pre-decision enforcement conferences before the NRC makes final enforcement decisions. Although TVA cannot predict the final outcome of these matters, it is reasonably possible that the NRC may direct TVA to change certain aspects of its operations and/or impose civil penalties on TVA.  TVA does not expect any such penalties to have a material adverse impact on its results of operations or financial condition.

Tritium-Producing Burnable Absorber Rods. TVA was a cooperating agency in the 2016 Department of Energy ("DOE") Final SEIS for the Production of Tritium in a Commercial Light Water Reactor. In 2017, due to an anticipated need for more tritium-producing burnable absorber rods ("TPBARs"), the DOE announced its preferred alternative for irradiation services, which included use of an additional reactor. As a result of TVA's assessment and concurrence with the DOE's alternative, TVA submitted a license amendment request to the NRC to authorize the irradiation of TPBARs in Watts Bar Unit 2. The NRC approved the request in 2019. TVA is projecting to begin tritium production in Watts Bar Unit 2 in the fall of 2021. The DOE's decision also allows for irradiation of TPBARs at Sequoyah in the future; however, TVA does not have plans to employ Sequoyah units for tritium production in the near term.

Extended Power Uprate. TVA has undertaken an extended power uprate ("EPU") project at Browns Ferry to increase the amount of electrical generation capacity of its reactors. The license for each reactor was amended to allow reactor operation at the higher power level. The Browns Ferry EPU license amendments were approved by the NRC in 2017, following a nearly two-year review.

The project involved extensive engineering analyses and modification and replacement of certain existing plant components to enable the units to produce the additional power requested by the license amendments. The project's total cost will be approximately $475 million. Physical work on all units was completed in 2019. The generating capacity is expected to increase by an estimated 465 MW that must be validated through operation of all units for four seasons and completion of additional testing. TVA is currently operating and testing the units through the required period to complete the validation of the increased generating capacity.

Plant Closures.  Results of assessments performed at Paradise and Bull Run were presented to the TVA Board at its February 2019 meeting. The TVA Board approved the retirement of Paradise Unit 3 by December 2020 and Bull Run by December 2023. Subsequent to the TVA Board approval, TVA determined that Paradise would not be restarted after January 2020 due to the plant's material condition. Paradise Fossil Plant Unit 3 was taken offline on February 1, 2020, effectively retiring the plant. See Note 5Plant Closures.

Optimum Energy Portfolio. TVA must continuously evaluate all generating assets to ensure an optimum energy portfolio that provides safe, clean, and reliable power while maintaining flexibility and fiscal responsibility to the people of the Tennessee Valley.  During its August 2019 meeting, the TVA Board approved the Integrated Resource Plan, which included plans to assess performance of all generating assets.  These assessments consider material condition, plant performance, system flexibility needs, environmental impacts, grid support, and other factors.  TVA is currently performing these assessments and will provide the findings to the TVA Board to inform long-term planning of its generating assets.  In addition, TVA is also considering plans for additional generating facilities to support flexible resources and renewable portfolio options.

    Coal Combustion Residuals Facilities. TVA has committed to a programmatic approach for the elimination of wet storage of coal combustion residuals ("CCR") within the TVA service area. Under this program ("CCR Conversion Program"), TVA is converting all operational coal-fired plants to dry CCR storage and closing all wet storage facilities.

Dry generation and dewatering projects. Conversion of coal plant CCR wet processes to dry generation or dewatering is complete at Bull Run, Shawnee, and Kingston Fossil Plant ("Kingston"). Construction at Gallatin Fossil Plant ("Gallatin") was completed during the first quarter of 2020. Construction is underway at Cumberland Fossil Plant ("Cumberland") and is scheduled for completion in late 2020. Fly ash and gypsum conversion projects at Paradise were completed in 2019. 

Landfills. TVA has made strategic decisions to build and maintain lined and permitted dry storage facilities on TVA-owned property at several TVA locations, allowing these facilities to operate beyond existing dry storage capacity. Currently, lined and permitted dry storage facilities are completed and operational at Bull Run, Kingston, and Gallatin, and a lined dry storage facility at Paradise has been constructed but is not yet operational. A lined dry storage facility at Shawnee is currently under construction with completion scheduled for September 2020. Construction of a lined dry storage facility at Cumberland is expected to start in 2021. Kingston's permitted lined dry storage expansion is scheduled for completion in 2021. TVA is designing and permitting a lateral expansion of the existing landfill at Gallatin. Additionally, TVA is initiating the design and permitting process for a new lined landfill at Bull Run, but no decision to construct the facility has been made at this time. Construction of additional lined facilities may occur to support future business requirements.

Wet CCR impoundment closures. TVA is working to close wet CCR impoundments in accordance with federal and state requirements. Closure project schedules and costs are driven by the selected closure methodology (such as closure-in-place or closure-by-removal). Closure initiation dates are driven by environmental regulations. TVA's predominant closure methodology is closure-in-place, with exceptions at certain facilities. TVA issued an environmental impact statement ("EIS") in June 2016 that addresses the closure of CCR impoundments at TVA's coal-fired plants. TVA issued its associated Record of Decision in July 2016. Although the EIS was designed to be programmatic in order to address the mode of impoundment closures, it specifically addressed closure methods at 10 impoundments. TVA subsequently decided to close those impoundments. The method of final closure for each of these facilities will depend on various factors, including the results of studies conducted pursuant to NEPA and approval by appropriate state regulators. Additional NEPA studies will be conducted as other facilities are designated for closure. See Note 11Asset Retirement Obligations.
    
Groundwater monitoring. Compliance with the Environmental Protection Agency's ("EPA's") CCR rule ("CCR Rule") as well as other requirements will require additional engineering and analysis as well as implementation of a comprehensive groundwater monitoring program. As further analyses are performed, including evaluation of monitoring results, there is the potential for additional costs for investigation and/or remediation. TVA expects to continue to evaluate and update these cost estimates.

In compliance with the CCR Rule, TVA published the results of additional groundwater testing at TVA's CCR facilities on March 1, 2019. The results included values above groundwater protection standards for some constituents at several CCR units. Accordingly, TVA will have to cease sending CCR and non-CCR wastestreams to any impacted unlined CCR surface impoundments no later than October 31, 2020 (and potentially earlier due to location demonstration results) and initiate additional corrective actions for groundwater. The EPA has proposed a rule revision that would change the deadline to cease sending CCR and non-CCR wastestreams to unlined CCR impoundments and to initiate closure by August 31, 2020. The proposed rule also allows for extensions based on meeting certain criteria. TVA evaluated and published Assessment of Corrective Measures reports to its CCR website in August 2019. TVA is continuing to publish periodic reports on additional groundwater testing at its CCR facilities; the latest report was published on February 28, 2020. In addition, TVA has been and will continue posting semi-annual progress reports on the status of remedy selection.

As of March 31, 2020, TVA had spent approximately $1.9 billion on its CCR Conversion Program. TVA expects to spend an additional $1.1 billion on the CCR Conversion Program through 2024. These estimates may change depending on the final closure method selected for each facility. Once the CCR Conversion Program is completed, TVA will continue to undertake certain CCR projects, including building new landfill cells under existing permits and closing existing cells once they reach capacity.

TVA was involved in two lawsuits concerning the CCR facilities at Gallatin. One of these cases was resolved by the entry of a consent order that became effective July 31, 2019. TVA agreed to close the existing wet ash impoundments by removal, either to an onsite landfill or to an offsite facility. TVA may also submit a plan that allows for beneficial reuse. TVA is currently conducting additional studies and environmental reviews to support its determination of the specific removal plans. See Note 11Asset Retirement Obligations.

In October 2019, the Tennessee Department of Environment and Conservation ("TDEC") released amendments to its regulations which govern solid waste disposal facilities, including TVA's active CCR facilities covered by a solid waste disposal permit and those which closed pursuant to a TDEC approved closure plan. Such facilities are generally subject to a 30-year post-closure care period during which the owner or operator must undertake certain activities, including monitoring and maintaining the facility. The amendments will, among other things, add an additional 50-year period after the end of the post-

63


closure care period, require TVA to submit recommendations as to what activities must be performed during this 50-year period to protect human health and the environment, and require TVA to submit revised closure plans every 10 years.

Potential Liability Associated with Workers' Exposure to CCR Materials. In response to the 2008 ash spill at Kingston, TVA hired Jacobs Engineering Group, Inc. ("Jacobs") to oversee certain aspects of the cleanup. After the cleanup was completed, Jacobs was sued in the United States District Court for the Eastern District of Tennessee ("Eastern District") by employees of a contractor involved in the cleanup and family members of some of the employees.  The plaintiffs alleged that Jacobs had failed to take or provide proper health precautions and misled workers about the health risks associated with exposure to coal fly ash, which is a CCR material. The plaintiffs alleged that exposure to the fly ash caused a variety of significant health issues and illnesses, including in some cases death. The case was split into two phases, with the first phase considering, among other issues, general causation and the second determining specific causation and damages. In 2018, a jury hearing the first phase returned a verdict in favor of the plaintiffs, including determinations that Jacobs failed to adhere to its contract with TVA or the Site Wide Safety and Health Plan in place; Jacobs failed to provide reasonable care to the plaintiffs; and Jacobs's failures were capable of causing a list of medical conditions, ranging from hypertension to cancer. In 2019, the district court referred the parties to mediation. Mediation has concluded, but the parties did not resolve the matter. The litigation will now proceed.

Further in 2019, an additional group of contractor employees and family members filed suit against Jacobs in the Circuit Court for Roane County, Tennessee. These plaintiffs have raised similar claims to those being litigated in the case referenced above.

While TVA is not a party to either of these lawsuits, TVA could be contractually obligated to reimburse Jacobs for some amounts that Jacobs is required to pay. TVA will continue monitoring the litigation to determine whether these or similar cases could have broader implications for the utility industry. TVA does not expect any potential liability to have a material adverse impact on its results of operations or financial condition. See Note 20Contingencies and Legal Proceedings Contingencies.

River Management. Rainfall and runoff in the Tennessee Valley through the second quarter of 2020 were 166 percent and 174 percent of normal, respectively. Above normal rainfall and runoff have continued to help TVA meet its river system commitments, including managing minimum river flows for navigation, generating low-cost hydroelectric power, maintaining water quality and water supply, and providing recreational opportunities for the Tennessee Valley.  In addition, having cool water available helps TVA to meet thermal compliance and support normal operation of TVA's nuclear and fossil-fueled plants, while oxygenating water helps fish species remain healthy.  Significant flooding occurred in portions of the Tennessee Valley during February 2020 after receiving 10.0 inches of rainfall, which was 223 percent of normal for the month and the third wettest February on record. Although many locations along the Tennessee River reached or exceeded flood stage, TVA's efforts, including storing water in large tributary reservoirs, accounted for approximately $1.0 billion in avoided damages in areas such as Chattanooga, Tennessee. Further, the second quarter of 2020 was the wettest second quarter on record with 24.6 inches of rainfall received. Rainfall and runoff in the Tennessee Valley during the second quarter of 2020 were 177 percent and 182 percent of normal, respectively.

Small Modular Reactors.  In 2015, DOE entered into an Interagency Agreement with TVA to fund 50 percent of site characterization activities and the development of an Early Site Permit Application ("ESPA") for a generic small modular reactor ("SMR"). The ESPA is based on the potential construction and operation of two or more SMR units at TVA's Clinch River Site in Oak Ridge, Tennessee. TVA submitted the ESPA for review by the NRC in 2016.  NRC staff concluded their environmental review and issued a final environmental impact statement in April 2019, followed by the conclusion of the safety review and issuance of a final safety evaluation report in June 2019.  The Commission held the statutorily required mandatory hearing for the ESPA in August 2019, and the permit was issued by the NRC in December 2019. The permit is valid through 2039 and therefore provides TVA a great deal of flexibility to make new nuclear decisions based on energy needs and economic factors.

TVA is in the process of evaluating new nuclear technology options and potential deployment scenarios.  To assist in the evaluation of SMRs, TVA has entered into memorandums of understanding with Oak Ridge National Laboratory and the University of Tennessee. These partnerships allow for collaboration, exploring highly efficient advanced reactor designs as a next-generation nuclear technology while leveraging advanced modeling and simulation tools to assist in determining the feasibility of SMRs. Any decision to construct an SMR would require approval by the TVA Board and the NRC. As of March 31, 2020, TVA had spent $77 million on work regarding SMRs, including work to complete the ESPA for the Clinch River Site, of which the DOE reimbursed TVA $24 million.  Additional expenditures will be determined based on future project development.

System Operations Center. A new system operations center has been approved for $255 million. The new secured facility is being built to accommodate a new energy management system and to adapt to new regulatory requirements.  The facility is expected to be constructed by 2022 and fully operational by 2024. As of March 31, 2020, TVA had spent approximately $19 million on the project and expects to spend an additional $236 million.

Dam Safety and Remediation Initiatives

Assurance Initiatives. TVA has an established dam safety program, which includes procedures based on the Federal Guidelines for Dam Safety, with the objective of reducing the risk of a dam safety event. The program is comprised of various engineering activities for all of TVA's dams including safety reassessments using modern industry criteria and the new probable maximum flood and site-specific seismic load cases. One aspect of the guidelines is that dam structures will be periodically assessed to assure that TVA's dams meet current design criteria. These assessments include material sampling of the dam and foundational structures and detailed engineering analysis.  TVA will continue preventative and ongoing maintenance as a part of this safety program.

Boone Dam Remediation. In 2015, a sinkhole was discovered near the base of the earthen embankment at Boone Dam, and a small amount of water and sediment was found seeping from the river bank below the dam. TVA identified underground pathways contributing to the seepage and prepared a plan to repair the dam, which consists of the construction of a composite seepage barrier wall in the dam's earthen embankment. TVA has completed grouting and construction of an upstream and downstream buttress. Installation of the concrete cut-off wall elements is in process.
    
As design and construction plans are finalized, the estimated cost and duration continue to be refined. As of March 31, 2020, TVA had spent $216 million related to this project and expects to spend an additional $240 million through 2023. TVA expects the reservoir to return to normal operations in 2022 and is continuing to work with the community to help mitigate local impacts of the extended drawdown.

Pickwick South Embankment Remediation. Reassessments of Pickwick Landing Dam ("Pickwick") found low safety factors for post-earthquake stability indicating that the dam is at significant risk for slope stability failure following a seismic event in portions of the south embankment. Slope stability failure could lead to a breach of the south embankment and loss of the reservoir, resulting in loss of life and damage to property downstream, disruption to navigation, and loss of generation and recreation.

TVA is upgrading the south embankment by constructing berms on the upstream and downstream slopes. The design phase of the project began in 2017 and is now completed. Construction began in the spring of 2019, and the project is currently estimated to be completed in two years, but could take longer depending on successful construction sequencing.  As of March 31, 2020, TVA had spent $111 million related to this project and expects to spend an additional $37 million through 2022.

Real Estate Portfolio

TVA continues to study its real estate portfolio for the purpose of aligning its real estate holdings with TVA's strategic direction. A comprehensive assessment of its real estate portfolio has been completed. TVA will continue to develop and implement a strategy aimed at reducing cost and right-sizing its portfolio as part of the effort.

Knoxville Property. In 2016, TVA completed a comprehensive assessment of its real estate holdings in the Knoxville, Tennessee region including the Knoxville Office Complex ("KOC") and adjacent Summer Place Complex ("SPC"). As a result of this study and a subsequent Environmental Assessment in 2017, TVA has consolidated its Knoxville area employees into the West Tower of the KOC and the Greenway Drive Transmission Service Center, and is completing the centralized field offices in Norris, Tennessee. As part of this consolidation effort, TVA has approved the conveyance of the SPC and the East Tower of the KOC. TVA expects to convey the KOC by the end of 2020.

Regulatory Compliance

Steam-Electric Effluent Guidelines. In 2015, the EPA published a final rule revising the existing steam-electric effluent limitation guidelines ("ELGs").  The ELGs update the existing technology-based water discharge limitations for power plants.  Compliance with new requirements is required in the 2018-2023 timeframe and will necessitate major upgrades to wastewater treatment systems at all coal-fired plants. Dry fly ash handling is mandated by the rule. The rule also requires either dry bottom ash handling systems or "no discharge" recycle of bottom ash transport waters, and new technology-based limits on flue gas desulfurization ("FGD") (scrubber) wastewater require primary physical/chemical treatment and secondary biological treatment to meet extremely low limits for arsenic, mercury, and selenium.

The EPA published a rule in 2017, postponing certain compliance/applicability dates to provide the EPA time to review and revise, as necessary, the 2015 ELGs for FGD wastewater and bottom ash transport water. The EPA delayed the compliance dates for these two waste streams from the 2018-2023 timeframe to 2020-2023. However, the 2018-2023 applicability dates and the accompanying requirements for fly ash transport water, flue gas mercury control wastewater, and gasification wastewater remain unchanged. While the EPA reconsiders the limits for FGD wastewater and bottom ash transport water, states have issued National Pollutant Discharge Elimination System ("NPDES") permits for all of TVA's active coal facilities based on the 2015 ELGs, recognizing that the permits may need to be reopened to incorporate modifications to those ELGs. The EPA proposed revised ELGs for bottom ash transport water and FGD wastewater on November 4, 2019.

65


The primary impact of these proposed regulations for TVA is on the operation of existing coal-fired generation facilities. The proposed revised ELGs could impact long-term investment decisions being made relative to the long-term compliance and operability of these plants. The proposed revisions may require TVA to install additional wastewater treatment systems for FGD wastewater and bottom ash transport water, and TVA could incur substantial costs to comply with the new rule. TVA currently has three plants with wet scrubbers that may be subject to new scrubber-related limits, the largest being Cumberland. Bull Run is exempt from the imposition of new scrubber-related limits due to the pending retirement of the plant prior to the regulatory deadline. The proposed revision also includes a subcategory for which Cumberland would qualify that provides TVA greater flexibility in meeting the ELGs. However, given that these are proposed rules, it is unclear as to the nature of the final impact to TVA.

Allen Groundwater Investigation.  The CCR Rule required TVA to implement a comprehensive groundwater monitoring program at units subject to the rule. As a result of this groundwater monitoring program, TVA reported to TDEC in 2017 elevated levels of arsenic, lead, and fluoride in groundwater samples collected from two shallow-aquifer groundwater monitoring wells around the Allen East Ash Disposal Area. TVA, under the oversight of TDEC, conducted a remedial investigation into the nature and extent of the contamination. In 2018, TVA submitted a draft Remedial Investigation Report to TDEC which was revised after discussions with TDEC and additional investigation. TVA submitted the Final Updated Remedial Investigation Report to TDEC in 2019.

The remedial investigation confirmed that the high arsenic, fluoride, and lead concentrations are limited to the shallow alluvial aquifer in the north and south areas of the Allen East Ash Disposal Area. These areas are not adversely impacting the Memphis aquifer, which is the source of the public drinking water supply. All samples taken from the Memphis aquifer through TVA production wells were below the EPA drinking water standards. As the result of a pumping test conducted on TVA production wells at the nearby Allen Combined Cycle Plant ("Allen CC") by the United States Geological Survey and the University of Memphis, TVA is committed to not operating these production wells until additional data supports safe use. TVA constructed water tanks on site and is purchasing cooling water from Memphis Light, Gas and Water. The use of water tanks rather than the wells may impose some operational restrictions on the Allen CC due to the lower availability of cooling water.

TDEC approved TVA's Remedial Investigation/Interim Response Action Groundwater Monitoring Plan in 2019. The plan will be reviewed and modified annually as required to support project needs. The 2020 Remedial Investigation/Interim Response Action Groundwater Monitoring Plan has been sent to TDEC. TVA sampled the monitoring wells around the Allen East Ash Disposal Area quarterly throughout CY 2019. TVA prepared a memorandum following each sampling event, and has issued an annual report that has been submitted to TDEC. TVA is currently in the process of finalizing the interim response action for a groundwater extraction system to control and begin treating the shallow groundwater that contains elevated concentrations of arsenic. TVA began dewatering the Allen East Impoundment in September 2019.

TVA has evaluated closure options for the Allen East Ash Disposal Area, as well as the nearby West Ash Impoundment, through an EIS pursuant to NEPA. In March 2019, TVA released its public scoping report, which eliminated closure-in-place as an alternative. TVA published the final EIS on March 13, 2020 and its Record of Decision on April 14, 2020, which documents the final decision regarding the closure method for the CCR units at the Allen Fossil Plant. TVA has decided to remove CCR from the above identified areas to an existing permitted offsite landfill.

Ratemaking

TVA, LPCs, and directly served industries have worked collaboratively in recent years to develop changes to rates that focus on TVA's long-term pricing efforts and the changing needs of customers in the Tennessee Valley. These changes have improved pricing by better aligning rates with underlying cost drivers and by sending improved pricing signals, while maintaining competitive industrial rates and keeping residential rates affordable.

In 2019, the TVA Board approved a 20-year Partnership Agreement option that better aligns the length of LPC contracts with TVA's long-term commitments. These agreements are automatically extended each year after their initial effective date, contingent upon certain circumstances, including agreement on flexibility options and limited rate increases going forward. Participating LPCs will receive benefits including a 3.1 percent wholesale bill credit in exchange for their long-term commitment, which enables TVA to recover its long-term financial commitments over a commensurate period. In addition, participating LPCs will have the option for flexible generation capacity up to approximately five percent of average total hourly energy sales over the prior five years. As of May 4, 2020, 139 LPCs had signed the 20-year Partnership Agreement with TVA.

Safeguarding Assets

Physical Security Non-Nuclear Asset Protection.  TVA utilizes a variety of security technologies, security awareness activities, and security personnel to prevent sabotage, vandalism, and thefts.  Any of these activities could negatively impact the ability of TVA to generate, transmit, and deliver power to its customers. TVA's Police and Emergency Management personnel are active participants with numerous professional and peer physical security organizations in both the electric industry and law enforcement communities.


66


Physical attacks on transmission facilities across the country have heightened awareness of the need to physically protect facilities. TVA continues to work with the North American Electric Reliability Corporation ("NERC"), the SERC Reliability Corporation, the North American Transmission Forum, and other utilities to implement industry approved recommendations and standards.

Nuclear Security. Nuclear security is carried out in accordance with federal regulations as set forth by the NRC. These regulations are designed for the protection of TVA's nuclear power plants, the public, and employees from the threat of radiological sabotage and other nuclear-related terrorist threats. TVA has security forces to guard against such threats.

Cybersecurity. TVA operates in a highly regulated environment with respect to cybersecurity. TVA's cybersecurity program aligns or complies with the Federal Information Security Management Act, the NERC Critical Infrastructure Protection requirements, and the NRC requirements for cybersecurity, as well as industry best practices. As part of the U.S. government, TVA coordinates with and works closely with the U.S. Department of Homeland Security and the U.S. Computer Emergency Readiness Team ("US-CERT"). US-CERT functions as a liaison between the U.S. Department of Homeland Security and the public and private sectors to coordinate responses to security threats from the internet.

The risk of cybersecurity events such as malicious code attacks, unauthorized access attempts, and social engineering attempts continues to intensify. While TVA and its third-party vendors and service providers have been, and will likely continue to be, subjected to such attacks and attempts to disrupt operations, to date the attacks have not impacted TVA's ability to operate as planned. See Item 1A, Risk Factors — Operational RisksTVA's facilities and information infrastructure may not operate as planned due to cyber threats to TVA's assets and operations in the Annual Report.

Over the last few years, there has been an increase of malicious cyber activity across all industries, including the energy sector. Recently, TVA has observed a significant increase in malicious activity related to the COVID-19 pandemic including phishing campaigns and malicious websites. These types of malicious activity are occurring across the industry and have also been observed by TVA’s external vendors, stakeholders and partners. This activity has caused the need for heightened awareness and preparedness. TVA is leveraging federal and other partners to better identify, detect, protect, and respond to these potential attacks. While there have been incidents of phishing and attempted fraud against TVA and its vendors and service providers, these events have not had a significant or material impact on business or operations.

Transmission Assets. In addition to physical and cybersecurity attacks, TVA's transmission assets are vulnerable to various types of electrically charged energy disruptions such as those from geomagnetic disturbances ("GMDs") and electromagnetic pulses ("EMP"). Because the effects of GMD and EMP are similar, they are often considered together. In September 2016, the Federal Energy Regulatory Commission ("FERC") approved a new standard to address GMD events, and in March 2020, FERC approved a revision to the standard. TVA has met the requirements of the original standard and subsequent revisions, and has evaluated the effects of solar storms ranging from NERC's reference case to possible extreme levels. TVA continues as an active participant with NERC in this field. The most serious threats from EMP are those caused by high-altitude nuclear explosions. Like others in the industry, TVA is coordinating with federal and state authorities, NERC, Electric Power Research Institute, and other grid owners and operators to address this concern.

Bulk-Power System Assets. On May 1, 2020, President Trump issued Executive Order ("EO") 13920, Securing the United States Bulk-Power System.  Among other things, the EO prohibits the acquisition or installation of any bulk-power system electric equipment where the transaction (1) involves any property in which any foreign country or a national thereof has any interest and (2) poses an undue risk to the bulk-power system in, or national security of, the United States. TVA is reviewing this EO and has not yet determined the extent to which this EO may impact TVA’s operations.

Environmental Matters

TVA's activities, particularly its power generation activities, are subject to comprehensive regulation under environmental laws and regulations relating to air pollution, water pollution, and management and disposal of solid and hazardous wastes, among other issues. Emissions from all TVA-owned and operated units (including small combustion turbine units of less than 25 MW) have been reduced from historic peaks. Emissions of nitrogen oxide ("NOx") have been reduced by 96 percent below peak 1995 levels and emissions of sulfur dioxide ("SO2") have been reduced by 99 percent below 1977 levels through CY 2019. For CY 2019, TVA's emission of carbon dioxide ("CO2") from its sources was 47 million tons, a 55 percent reduction from 2005 levels. This amount includes 2,383 tons from units rated at less than 25 MW. To remain consistent and to align with the EPA's reporting requirements, TVA intends to continue reporting CO2 emissions on a calendar year basis.

Clean Air Act

The CAA establishes a comprehensive program to protect and improve the nation's air quality and control sources of air pollution. The major CAA programs that affect TVA's power generation activities are described below.

National Ambient Air Quality Standards. The CAA requires the EPA to set National Ambient Air Quality Standards ("NAAQS") for certain air pollutants. The EPA has done this for ozone, particulate matter ("PM"), SO2, nitrogen dioxide ("NO2"), carbon monoxide, and lead. Over the years, the EPA has made the NAAQS more stringent. Each state must develop a plan to

67


be approved by the EPA for achieving and maintaining NAAQS within its borders. These plans impose limits on emissions from pollution sources, including TVA fossil fuel-fired plants. Areas meeting a NAAQS are designated as attainment areas. Areas not meeting a NAAQS are designated as non-attainment areas, and more stringent requirements apply in those areas, including stricter controls on industrial facilities and more complicated permitting processes. TVA fossil fuel-fired plants can be impacted by these requirements. All TVA generating units are located in areas designated as in attainment with NAAQS.

Cross-State Air Pollution Rule. The EPA issued the Cross-State Air Pollution Rule ("CSAPR") in July 2011 requiring several states in the eastern U.S. to improve air quality by reducing power plant emissions that contribute to pollution in other states.  In 2016, the EPA issued an update to CSAPR to address cross-state air pollution (the "CSAPR Update Rule"). The EPA subsequently issued an additional rule to resolve any remaining cross-state air pollutant issues ("CSAPR Close-Out Rule"). The U.S. Court of Appeals for the District of Columbia Circuit ("D.C. Circuit") has remanded a portion of the CSAPR Update Rule back to the EPA to address its failure to require upwind states to eliminate substantial contributions to downwind nonattainment by the statutory deadline. The D.C. Circuit also vacated the CSAPR Close-Out Rule. TVA does not anticipate significant changes to its operations based on the CSAPR Update Rule and the CSAPR Close-Out Rule, but cannot predict how the EPA will respond to the previously mentioned court decisions in amending these rules.

Mercury and Air Toxics Standards for Electric Utility Units. On April 16, 2020, the EPA issued a final rule which revokes the agency’s earlier finding that regulation of hazardous air pollutants ("HAP") emitted from steam electric utilities is “appropriate and necessary.” The rule does not remove electric generating units from the source categories listed under Section 112 of the CAA nor does it rescind the MATS requirements. Additionally, the EPA determined that further restrictions on HAP emissions are not warranted based on a residual risk and technology review for this source category. TVA does not anticipate that the final rule will change TVA's MATS compliance requirements or strategy.

Environmental Agreements. See Note 20Contingencies and Legal Proceedings Legal Proceedings Environmental Agreements for a discussion of the Environmental Agreements, which discussion is incorporated herein by reference.

Acid Rain Program. The Acid Rain Program is intended to help reduce emissions of SO2 and NOx, which are the primary pollutants implicated in the formation of acid rain. The program includes a cap-and-trade emission reduction program for SO2 emissions from power plants. TVA continues to reduce SO2 and NOx emissions from its coal-fired plants, and the SO2 allowances allocated to TVA under the Acid Rain Program are sufficient to cover the operation of its coal-fired plants. In the TVA service area, the limitations imposed on SO2 and NOx emissions by the CSAPR program are more stringent than the Acid Rain Program. Therefore, TVA forecasts that the Acid Rain Program will not impose any additional material requirements on TVA.

Regional Haze Program. The EPA issued the Clean Air Visibility Rule, which required certain older sources to install best available retrofit technology. No additional controls or lower operating limits are required for any TVA units to meet best available retrofit technology requirements. In January 2017, the EPA published the final rule that changed some of the requirements for Regional Haze State Implementation Plans ("SIPs"). Specific impacts cannot be determined until future Regional Haze SIPs are developed.

Opacity. Opacity, or visible emissions, measures the denseness (or color) of power plant plumes and has traditionally been used by states as a means of monitoring good maintenance and operation of particulate control equipment. Under some conditions, retrofitting a unit with additional equipment to better control SO2 and NOx emissions can adversely affect opacity performance, and TVA and other utilities have addressed this issue. The evaluation of utilities' compliance with opacity requirements is coming under increased scrutiny, especially during periods of startup, shutdown, and malfunction. Historically, SIPs developed under the CAA typically excluded periods of startup, shutdowns, and malfunctions, but in June 2015, the EPA finalized a rule to eliminate such exclusions. The EPA rule required states to modify their implementation plans by November 2016. Kentucky, Tennessee, and Mississippi submitted implementation plans, but Alabama has not. Environmental petitioners and several states filed petitions for judicial review of the EPA final rule before the D.C. Circuit. In April 2017, the D.C. Circuit, at the request of the new EPA Administrator, ordered this litigation to be suspended pending the EPA's review to determine whether to reconsider all or part of the rule. TVA does not expect significant impacts from these rule changes.

New York Petition to Address Impacts from Upwind High Emitting Sources. In March 2018, the State of New York filed a petition with the EPA under Section 126(b) of the CAA to address ozone impacts on New York from the NOx emissions from sources emitting at least 400 tons of NOx in CY 2017 from nine states including Kentucky. The New York petition requests that the EPA require daily NOx limits for utility units with SCRs such as Shawnee Units 1 and 4 and emission reductions from utility units without SCRs such as Shawnee Units 2, 3 and 5-9. Kentucky utility unit NOx emissions are already limited by the CSAPR Update Rule and are declining, and current EPA modeling projects no additional requirements to reduce Kentucky NOx emissions are necessary. On September 20, 2019, the EPA finalized its denial of New York's petition because the state did not demonstrate, and the EPA could not independently establish, that sources in the states listed in the petition contribute to exceedances of the 2008 and 2015 ozone NAAQS in New York. On October 29, 2019, the State of New York filed a petition in the D.C. Circuit for judicial review of the EPA's denial of the petition. Specific impacts to TVA as a result of the filing of the petition for judicial review cannot be determined at this time.
    

68


Affordable Clean Energy Rule. On June 19, 2019, the EPA finalized the final Affordable Clean Energy ("ACE") rule and repealed the EPA's previous regulation addressing greenhouse gas ("GHG") emissions from existing fossil fuel-fired units. The ACE rule establishes guidelines for GHG emissions from existing coal-fired units based on efficiency improvements that can be achieved at those units at reasonable cost. States are required to apply the emission guidelines to coal-fired units within their respective jurisdictions and take into account the remaining useful lives of those units. The impact of the ACE rule on TVA's coal-fired units cannot be determined until Tennessee and Kentucky submit to the EPA their SIPs implementing guidelines in the ACE rule and the EPA approves these SIPs. The ACE rule allows states three years to submit their SIPs and allows the EPA 18 months for approval.
    
New Source Performance Standards. On December 6, 2018, the EPA proposed revisions to the GHG emission standards for new, modified, and reconstructed electric utility generating units that were finalized by the EPA in October 2015. For coal-fired units, the EPA proposes to revise the current new source standards such that carbon capture and sequestration technology is no longer necessary to meet the standards of performance that reflect the best system of emission reduction. The resulting limits are less stringent than limits under the current rule and can be met by modern coal-fired units (e.g., supercritical steam generators) in combination with best operating practices, but without carbon capture and sequestration. The EPA is not proposing to revise the new source performance standard for GHG emission from gas-fired units. If finalized as proposed, the revisions are not expected to significantly impact TVA since TVA does not currently plan to construct, modify, or reconstruct any coal-fired units.

Maryland Petition to Address Impacts from Upwind Electric Generating Units. In September 2017, the State of Maryland filed a lawsuit against the EPA for failing to act within 60 days on Maryland's petition under Section 126 of the CAA to address ozone impacts on Maryland from the NOx emissions of 36 electric generating units, including TVA's Paradise coal-fired Unit 3. The EPA has denied the petition because existing regulations already address emissions from the generating units at issue. On October 15, 2018, the State of Maryland filed a petition for judicial review with the D.C. Circuit asking the court to review the EPA's decision. With the retirement of Paradise Unit 3 on February 1, 2020, the outcome of this litigation will not affect TVA.

Climate Change

Executive Actions. In March 2017, President Trump issued EO 13783, "Promoting Energy Independence and Economic Growth."  The EO reversed or altered many actions taken by the federal government in the last four years of the Obama Administration to address climate change and mandates that federal agencies review existing regulations and actions that potentially burden energy development and use.  Several EOs, policy statements, and reports that established climate change objectives were rescinded or revoked.  EO 13783 did not mandate that the EPA reconsider its finding under the CAA that GHG emissions cause climate change and therefore endanger public health and the environment.

While EO 13783 requires review of all agency actions that potentially burden the safe, efficient development of domestic energy resources, the final specific requirements and impacts from implementation of this EO are not possible to predict at this time. It is likely that there will be some delay in the development of future GHG reduction requirements.

In May 2018, EO 13834, "Efficient Federal Operations," was signed. EO 13834 emphasizes meeting statutory requirements and gives agencies greater flexibility and discretion to decide how best to improve operations in order to "optimize energy and environmental performance, reduce waste, and cut costs." It also calls on the White House Council of Environmental Quality to streamline pre-existing environmental orders by "refocusing agencies on cost-effectively meeting mandates and goals" established by law. The order seeks to consolidate requirements related to energy and water efficiency, high performance buildings, renewable energy consumption, and federal vehicle fleet management. TVA consistently seeks to improve its operations in order to optimize energy and environmental performance and does not anticipate significant changes in its planning or operations as a result of the new EO.

International Accords. In September 2016, the U.S. formally accepted the Paris Agreement. The agreement met the threshold of at least 55 countries that account for at least 55 percent of global GHG emissions and formally entered into force in November 2016. The durability of the Paris Agreement commitments is uncertain after President Trump's announcement in June 2017 that the U.S. would withdraw from the agreement. On November 4, 2019, the United States formally notified the United Nations that it would withdraw from the agreement. Under the terms of the agreement, the effective date for the withdrawal will be November 4, 2020. Specific impacts to TVA cannot be determined at this time.
In response to President Trump's Paris withdrawal announcement, 25 states have formed the U.S. Climate Alliance, a bipartisan coalition of governors committed to reducing GHG emissions consistent with the goals of the Paris Agreement. North Carolina and Virginia are the only states in the TVA region that are U.S. Climate Alliance members. Among other commitments, each state commits to implement policies that advance the goals of the Paris Agreement, aiming to reduce GHG emissions by at least 26-28 percent below CY 2005 levels by CY 2025 and to accelerate new and existing policies to reduce carbon pollution and promote clean energy deployment at the state and federal level. In June 2017, America's Pledge was announced as a collaborative opportunity for these states to work with U.S. cities and businesses representing more than half of the U.S. economy. In September 2018, America's Pledge released its economy-wide policy analysis with recommendations of how

69


states, cities, businesses, and other stakeholders can influence U.S. decarbonization. It is premature to determine potential impacts to TVA.

Litigation. In addition to legislative activity, climate change issues have been the subject of a number of lawsuits, including lawsuits against TVA. See Note 20Contingencies and Legal Proceedings for additional information.
Indirect Consequences of Regulation or Business Trends. Legal, technological, political, and scientific developments regarding climate change may create new opportunities and risks. The potential indirect consequences could include an increase or decrease in electricity demand, increased demand for generation from alternative energy sources, and subsequent impacts to business reputation and public opinion.

Physical Impacts of Climate Change. TVA's Climate Change Adaptation Plan was last updated in June 2018. The goal of the adaptation planning process is to ensure TVA continues to achieve its mission and program goals and to operate in a secure, effective, and efficient manner in a changing climate by integrating climate change adaptation efforts in coordination with state and local partners, tribal governments, and private stakeholders. TVA manages the potential effects of climate change on its mission, programs, and operations within its environmental management processes.

Actions Taken by TVA to Reduce GHG Emissions. TVA has reduced GHG emissions from both its generation stations and its operations.  Recent TVA Board actions have focused on TVA's plan to balance its coal-fired generation by increasing its nuclear capacity, modernizing its hydroelectric generation system, increasing natural gas-fired generation, installing emission control equipment on certain of its coal-fired units, increasing its purchases of renewable energy, building solar facilities, and investing in energy efficiency initiatives to reduce energy use in the Tennessee Valley.  Additionally, TVA has invested to reduce energy use in its operations.  The combination of more stringent environmental regulations, lower natural gas prices, and lower demand for energy across the Tennessee Valley has reduced the utilization of coal-fired generation.  These factors have resulted in lower CO2 emissions from the TVA system.

Renewable/Clean Energy Standards

Twenty-nine states and the District of Columbia have established enforceable or mandatory requirements for electric utilities to generate a certain amount of electricity from renewable sources.  One state within the TVA service area, North Carolina, has a mandatory renewable standard that, while not applying directly to TVA, does apply to TVA's LPCs serving retail customers in that state.  TVA's policy is to provide compliance assistance to any distributor of TVA power, and TVA is providing assistance to the covered LPCs that sell TVA power in North Carolina.  Likewise, the Mississippi Public Service Commission adopted an energy efficiency rule applying to electric and natural gas providers in the state, and TVA is supplying information on participation in TVA's energy efficiency programs to support the covered Mississippi LPCs.

Water Quality Control Developments

Cooling Water Intake Structures. In May 2014, the EPA released a final rule under Section 316(b) of the Clean Water Act relating to cooling water intake structures ("CWIS") for existing power generating facilities. The rule requires changes in CWIS used to cool the vast majority of coal, gas, and nuclear steam-electric generating plants and a wide range of manufacturing and industrial facilities in the U.S.  The final rule requires CWIS to reflect the best technology available for minimizing adverse environmental impacts, primarily by reducing the amount of fish and shellfish that are impinged or entrained at a cooling water intake structure. These new requirements will potentially affect a number of TVA's fossil- and nuclear-fueled facilities and will likely require capital upgrades to ensure compliance. Most TVA facilities are projected to require retrofit of CWIS with "fish-friendly" screens and fish return systems to achieve compliance with the new rule. The rule is being implemented through permits issued under the National Pollutant Discharge Elimination System ("NPDES") in Section 402 of the Clean Water Act. State agencies administer the NPDES permit program in most states including those in which TVA's facilities are located.  In addition, the responsible state agencies must provide all permit applications to the U.S. Fish and Wildlife Service for a 60-day review prior to public notice and an opportunity to comment during the public notice. As a result, the permit may include requirements for additional studies of threatened and endangered species arising from U.S. Fish and Wildlife Service comments and may require additional measures be taken to protect threatened and endangered species and critical habitats directly or indirectly related to the plant cooling water intake. TVA's review of the final rule indicates that the rule offers adequate flexibility for cost-effective compliance.  The required compliance timeframe is linked to plant specific NPDES permit renewal cycles (i.e., technology retrofits), and compliance is expected to be required in the CYs 2022-2024 timeframe.

The EPA has never applied the requirements under Section 316(b) to hydroelectric facilities. However, two EPA regions that do not cover TVA's activities are proposing to include Section 316(b) requirements in NPDES permits for hydroelectric facilities in those regions. It is not clear whether the requirements will be adopted nationwide or, given the unique features of hydroelectric facilities and the manner in which they withdraw cooling water, how the best technology available standard would be applied.

Hydrothermal Discharges. The EPA and many states continue to focus regulatory attention on potential effects of hydrothermal discharges. Many TVA plants have variances from thermal standards under Section 316(a) of the Clean Water Act that are subject to review as NPDES permits are renewed. Specific data requirements in the future will be determined based on

70


negotiations between TVA and regulators. If plant thermal limits are made more stringent, TVA may have to install cooling towers at some of its plants and operate installed cooling towers more often. This could result in a substantial cost to TVA.

Steam-Electric Effluent Guidelines. In 2015, the EPA revised existing steam-electric effluent limitation guidelines ("ELGs"), which regulate water discharge pollutants and require the application of certain pollutant control technologies. The 2015 ELGs establish more stringent performance standards for existing and new sources and will require major upgrades to wastewater treatment options at all coal-fired plants. Compliance with new requirements was originally required in the CYs 2018-2023 timeframe, but the EPA delayed the compliance for flue gas desulfurization ("FGD") wastewater and bottom ash transport water until CYs 2020-2023 to allow the EPA time to review and potentially revise the ELGs with regard to these waste streams.

In August 2017, the EPA Administrator announced his decision to conduct a rulemaking to potentially revise the new, more stringent effluent limitations that apply to bottom ash transport water and FGD wastewater in the CY 2015 ELG rule. In April 2019, the United States Court of Appeals for the Fifth Circuit ("Fifth Circuit") remanded portions of the 2015 ELG because it determined that some of the standards did not comply with statutory requirements. The EPA proposed revised ELGs for bottom ash transport water and FGD wastewater on November 4, 2019, but did not address the portions of the ELG that were remanded by the Fifth Circuit.

The primary impact for TVA is on the operation of existing coal-fired generation facilities. The proposed revised ELGs could impact long-term investment decisions being made relative to the long-term compliance and operability of these plants. The proposed revisions may require TVA to install additional wastewater treatment systems for FGD wastewater and bottom ash transport water, and TVA could incur substantial costs to comply with the new rule.  The proposed revision also includes a subcategory for which the Cumberland Fossil Plant ("Cumberland") would qualify that provides TVA greater flexibility in meeting the ELGs. However, given that these are proposed rules, it is unclear what the final impact to TVA will be.  The proposed revisions may require TVA to install additional wastewater treatment systems for FGD wastewater and bottom ash transport water, and TVA could incur substantial costs to comply with the new rule.
    
Other Clean Water Act Requirements. As is the case in other industrial sectors, TVA and other utilities are also facing more stringent requirements related to the protection of wetlands, reductions in storm water impacts from construction activities, new water quality criteria for nutrients and other pollutants, new wastewater analytical methods, and regulation of pesticide discharges.

Recent Clean Water Act Decisions

On April 23, 2020, in County of Maui v. Hawaii Wildlife Fund, the Supreme Court held that the Clean Water Act requires a permit when there is a direct discharge of pollutants from a point source to waters of the U.S. and when there is the “functional equivalent” of a direct discharge.  The Court acknowledged that the new test would be somewhat difficult to apply, potentially requiring evaluation of multiple factors, but noted that “time and distance” of pollutant migration often will be the most important factors.  TVA cannot determine at this time what impact the decision and application of the test will have on its operations.

On April 15, 2020, in Northern Plains Resource Council v. U.S. Army Corps of Engineers, the U.S. District Court for the District of Montana vacated the Nationwide Permit (“NWP”) 12, which authorizes discharges of dredged or fill material into waters of the U.S.  The decision means that any projects relying on coverage under NWP 12 to authorize impacts to waters of the U.S. no longer have that coverage.  TVA is evaluating how many projects are currently proceeding under NWP 12.  These projects will be required to obtain authorization under other Nationwide Permits or by individual permits.  The decision will likely result in delays and cost increases.

Cleanup of Solid and Hazardous Wastes

Liability for releases and cleanup of hazardous substances is imposed under the federal Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), and other federal and parallel state statutes. In a manner similar to many other industries and power systems, TVA has generated or used hazardous substances over the years.

TVA Sites. TVA operations at some of its facilities have resulted in contamination that TVA is addressing including at TVA's Environmental Research Center at Muscle Shoals, Alabama. At March 31, 2020, TVA's estimated liability for cleanup and similar environmental work for those sites for which sufficient information was available to develop a cost estimate is approximately $12 million and was included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. In addition, the ERC has an active groundwater monitoring program as part of a Resource Conservation and Recovery Act ("RCRA") Corrective Action Permit.

Non-TVA Sites. TVA is aware of alleged hazardous-substance releases at certain non-TVA areas for which it may have some liability. See Note 20Contingencies and Legal Proceedings Environmental Matters.

Coal Combustion Residuals. The EPA published its final rule governing CCR in April 2015. The rule regulates CCR as nonhazardous waste under Subtitle D of the RCRA. While states may adopt the rule's requirements into their regulatory programs, the rule does not require states to adopt the requirements. The initial version of the rule provided for self-implementation by utilities and allows enforcement through citizen suits in federal court. The Water Infrastructure Improvements for the Nation Act ("WIIN Act") subsequently allowed state or federal-based permitting to implement the CCR rule as an alternative to self-implementation and citizen suits. The rule, which became effective in October 2015, has later effective dates for certain provisions. See Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — Key Initiatives and Challenges Generation Resources Coal Combustion Residual Facilities in the Annual Report for a discussion of the impact on TVA's operations, including the cost and timing estimates of related projects.
    
  In July 2018, the EPA issued a final rule which provided additional flexibility and an extension of certain deadlines. On March 13, 2019, the D.C. Circuit granted the EPA's request to remand this final rule to allow the EPA to reconsider the amendments to the CCR Rule. The remand also allows the EPA additional time to complete a new rulemaking to establish revised timelines for unlined impoundments to initiate closure and to reexamine the October 2020 deadline for closing some unlined impoundments. On August 14, 2019, the EPA issued a proposed rule to amend portions of the CCR Rule regarding beneficial use, temporary piles, and public access to information. As a result of these developments, it is not possible to predict potential impacts on TVA.

On November 4, 2019, the EPA announced a proposed rule that will revise portions of the CCR Rule requiring closure of unlined surface impoundments. This proposal, if finalized, will require all unlined CCR surface impoundments to stop receiving CCR and non-CCR wastestreams and to initiate closure by no later than August 31, 2020. The proposed rule would allow a utility to demonstrate the need for a short-term extension to continue to use the unlined CCR surface impoundment until November 30, 2020, if the alternative disposal capacity (i.e., new landfills or non-CCR water management systems) is not complete. Additionally, the proposed rule provides a process for a utility to seek site-specific approval from the EPA to continue to use the unlined CCR surface impoundment until no later than October 15, 2023. TVA does not currently anticipate the proposed rule will have a significant impact because TVA is already planning to close its unlined CCR surface impoundments.

In August 2015, TDEC issued an order that (1) allowed TDEC to oversee TVA's implementation of the EPA's CCR rule and (2) required TVA to assess CCR contamination risks at seven of TVA's eight coal-fired plants in Tennessee and to remediate any unacceptable risks.  The TDEC order does not allege that TVA is violating any CCR regulatory requirements nor does it assess TVA penalties.  The TDEC order sets out an iterative process through which TVA and TDEC will identify and evaluate any CCR contamination risks and, if necessary, respond to such risks.

Groundwater Contamination. Environmental groups and state regulatory agencies are increasing their attention on alleged groundwater contamination associated with CCR management activities. As a result, TVA may have to change how it manages CCR at some of its plants, potentially resulting in higher costs. See Part I, Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations — Key Initiatives and ChallengesGeneration ResourcesCoal Combustion Residuals Facilities and Note 11Asset Retirement Obligations.
Environmental Investments

From 1970 to 2019, TVA spent approximately $6.8 billion on controls to reduce emissions from its coal-fired power plants. In addition, TVA has reduced emissions by idling or retiring coal-fired units and relying more on cleaner energy resources including natural gas and nuclear generation.

TVA currently anticipates spending significant amounts on environmental projects through 2024, including investments in new clean energy generation including renewables to reduce TVA's overall environmental footprint.  TVA environmental project expenditures also result from coal-fired plant decommissioning and from effective ash management modernization. Based on TVA's decisions regarding certain coal-fired units, the amount and timing of expenditures could change.

SO2 Emissions and NOx Emissions. To reduce SO2 emissions, TVA operates scrubbers on 19 of its coal-fired units and switched to lower-sulfur coal at 13 coal-fired units. To reduce NOx emissions, TVA operates SCRs on 19 coal-fired units, operates low-NOx burners or low-NOx combustion systems on 19 units, operates over-fire air on one cyclone unit, optimized combustion on six units, and operates NOx control equipment year round when units are operating (except during start-up, shutdown, and maintenance periods). TVA has also retired 33 of 59 coal-fired units. Except for seven units at Shawnee, the remaining coal-fired units have scrubbers and SCRs.

Particulate Emissions. To reduce particulate emissions of air pollutants, TVA has equipped all of its coal-fired units with scrubbers, mechanical collectors, electrostatic precipitators, and/or bag houses.

Greenhouse Gas Emissions. There could be additional material costs if further reductions of GHGs, including CO2, are mandated by legislative, regulatory, or judicial actions and if more stringent emission reduction requirements for conventional pollutants are established. These costs cannot reasonably be predicted at this time because of the uncertainty of these actions.

72


The EPA may issue regulations establishing more stringent air, water, and waste requirements, and these requirements could result in significant changes in the structure of the U.S. power industry, especially in the eastern half of the country.

Legal Proceedings

From time to time, TVA is party to or otherwise involved in lawsuits, claims, proceedings, investigations, and other legal matters ("Legal Proceedings") that have arisen in the ordinary course of conducting its activities, as a result of catastrophic events or otherwise. At March 31, 2020, TVA had accrued $13 million with respect to Legal Proceedings. No assurance can be given that TVA will not be subject to significant additional claims and liabilities. If actual liabilities significantly exceed the estimates made, TVA's results of operations, liquidity, and financial condition could be materially adversely affected.

For a discussion of certain current material Legal Proceedings, see Note 20 Contingencies and Legal Proceedings Legal Proceedings, which discussions are incorporated into this Part I, Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations.

Off-Balance Sheet Arrangements
    
At March 31, 2020, TVA had no off-balance sheet arrangements.

Critical Accounting Policies and Estimates

The preparation of financial statements requires TVA to estimate the effects of various matters that are inherently uncertain as of the date of the financial statements. Although the financial statements are prepared in conformity with accounting principles generally accepted in the U.S., TVA is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses reported during the reporting period. Each of these estimates varies in regard to the level of judgment involved and its potential impact on TVA's financial results. Estimates are deemed critical either when a different estimate could have reasonably been used, or where changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact TVA's financial condition, results of operations, or cash flows. TVA's critical accounting policies are discussed in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates and Note 1Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in the Annual Report.

New Accounting Standards and Interpretations

Legislative and Regulatory Matters

TVA continues to monitor how regulatory agencies are interpreting and implementing the provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which was enacted in July 2010.  As a result, TVA has become subject to
recordkeeping, reporting, and reconciliation requirements related to its derivative transactions. In addition, depending on how regulatory agencies interpret and implement the provisions, TVA's hedging costs may increase, and TVA may have to post additional collateral and margin in connection with its derivative transactions.

TVA does not engage, and does not control any entity that is engaged, in any activity listed under Section 13(r) of the Securities Exchange Act of 1934 ("Exchange Act"), which requires certain issuers to disclose certain activities relating to Iran involving the issuer and its affiliates.  Based on information supplied by each such person, none of TVA's directors and executive officers are involved in any such activities.  While TVA is an agency and instrumentality of the U.S., TVA does not believe its disclosure obligations, if any, under Section 13(r) extend to the activities of any other departments, divisions, or agencies of the U.S.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Financial markets have experienced higher volatility during the second quarter of 2020 due to the COVID-19 pandemic. The uncertainty has resulted in significantly lower market valuations for many investments and derivative instruments. See Note 14Risk Management Activities and Derivative Transactions for additional information regarding TVA's derivative transactions and risk management activities, Note 15Fair Value Measurements for disclosure of the current balances of investment funds, and Note 19Benefit Plans for additional information regarding the impacts to TVA's pension system.


ITEM 4.  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

TVA's management, including the President and Chief Executive Officer, the Executive Vice President and Chief Financial Officer, and members of the Disclosure Control Committee, including the Vice President and Controller (Principal Accounting Officer), evaluated the effectiveness of TVA's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of March 31, 2020.  Based on this evaluation, TVA's management, including the President and Chief Executive Officer, the Executive Vice President and Chief Financial Officer, and members of the Disclosure Control Committee, including the Vice President and Controller (Principal Accounting Officer), concluded that TVA's disclosure controls and procedures were effective as of March 31, 2020, to ensure that information required to be disclosed by TVA in reports that it files or submits under the Exchange Act, is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by TVA in such reports is accumulated and communicated to TVA's management, including the President and Chief Executive Officer, the Executive Vice President and Chief Financial Officer, and members of the Disclosure Control Committee, including the Vice President and Controller (Principal Accounting Officer), as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

During the quarter ended March 31, 2020, there were no changes in TVA's internal control over financial reporting
that materially affected, or are reasonably likely to materially affect, TVA's internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

From time to time, TVA is party to or otherwise involved in lawsuits, claims, proceedings, investigations, and other legal matters ("Legal Proceedings") that have arisen in the ordinary course of conducting its activities, as a result of catastrophic events or otherwise.  While the outcome of the Legal Proceedings to which TVA is a party cannot be predicted with certainty, any adverse outcome to a Legal Proceeding involving TVA may have a material adverse effect on TVA's financial condition, results of operations, and cash flows.

For a discussion of certain current material Legal Proceedings, see Note 20Contingencies and Legal ProceedingsLegal Proceedings, which discussions are incorporated by reference into this Part II, Item 1, Legal Proceedings.


74


ITEM 1A.  RISK FACTORS

The following risk factor describes a material change from the risk factors disclosed in Item 1A, Risk Factors of the Annual Report. The following information should be read in conjunction with additional risk factors included in the Annual Report.

Events such as health epidemics, pandemics, and similar outbreaks could adversely affect TVA’s business, financial condition, and results of operations.

Health epidemics, pandemics, and similar outbreaks, including the global pandemics resulting from the outbreak of the Coronavirus Disease 2019 (“COVID-19”) and efforts to contain the virus, can adversely affect TVA’s business, financial condition, and results of operations. Such impacts can include reduced revenues as customers curtail operations to reduce the spread of the outbreak, including quarantines, closures, or reduced operations of businesses or other institutions, deferral of revenues under programs such as that offered by TVA to its local power company customers to offset the impact of customers’ inability to pay during the outbreak, and the impairment of accounts and loans receivable. Based on initial forecasts of early data, TVA anticipates base revenue to be lower than plan by between $300 million and $500 million for the remainder of 2020.

In addition, TVA’s operations could be impacted by, among other things, the need to implement social distancing to prevent illness from spreading within the workforce, travel restrictions, the availability of the workforce to perform essential functions, and the unavailability of fuel or critical parts, supplies, or services due to transportation restrictions and the shutdown, slowdown, or inability to meet contractual requirements of suppliers or other vendors in TVA’s supply chain. In addition, the continued spread of the COVID-19 pandemic could adversely impact TVA’s ability to develop, construct, and operate facilities and could lead to impairments of TVA's long-lived assets.

TVA could be further adversely affected by general impacts of the outbreak on the economy and financial markets, including an economic downturn and continued volatility in interest rates, commodity prices, investment performance, and foreign currency exchange rates. The value of TVA’s pension plan assets and other investment portfolios decreased significantly during the second quarter of 2020 and may continue to decrease, possibly by significant amounts.

To address specific aspects of the COVID-19 pandemic, TVA has implemented a company-wide pandemic plan, including limiting business related travel and encouraging working remotely when possible, implementing strong physical and cyber-security measures, closing certain recreation areas to slow the spread of the virus, actively monitoring generation, transmission, and distribution functions, and increasing its cash reserves; however, it is possible that these measures will not be successful in mitigating the impact of the outbreak.

The extent to which the COVID-19 pandemic will impact TVA’s business, financial condition, and results of operations is uncertain and will depend on numerous evolving factors beyond TVA’s knowledge or control including, among other things, the duration and severity of the outbreak, actions taken to contain its spread and mitigate its effects, and broader impacts of the COVID-19 pandemic on the country and region’s economy. However, TVA reasonably anticipates that a prolonged outbreak could have a material impact on its business, financial condition, and results of operations, and could require TVA to change how it conducts certain operations, takes power under certain agreements, or dispatches its own facilities.

ITEM 5. OTHER INFORMATION

On May 4, 2020, TVA amended and restated its Deferred Compensation Plan to align with competitive practice. The plan is designed to provide participants with deferrals of compensation in order to provide income to supplement retirement benefits, an additional means of deferring taxes on deferred compensation, and an opportunity to earn a notational investment return on deferred compensation. A copy of the plan is filed as Exhibit 10.2 to this Quarterly Report.
