Filing Format

This combined quarterly report on Form 10-Q is being filed separately by MGE Energy, Inc. (MGE Energy) and Madison Gas and Electric Company (MGE). MGE is a wholly owned subsidiary of MGE Energy and represents a majority of its assets, liabilities, revenues, expenses, and operations. Thus, all information contained in this report relates to, and is filed by, MGE Energy. Information that is specifically identified in this report as relating solely to MGE Energy, such as its financial statements and information relating to its nonregulated business, does not relate to, and is not filed by, MGE.

Forward-Looking Statements

This report, and other documents filed by MGE Energy and MGE with the Securities and Exchange Commission (SEC) from time to time, contain forward-looking statements that reflect management's current assumptions and estimates regarding future performance and economic conditions—especially as they relate to future load growth, revenues, expenses, capital expenditures, financial resources, regulatory matters, and the scope and expense associated with future environmental regulation. These forward-looking statements are made pursuant to the provisions of the Private Securities Litigation Reform Act of 1995. Words such as "believe," "expect," "anticipate," "estimate," "could,""should," "intend," and other similar words generally identify forward-looking statements. Both MGE Energy and MGE caution investors that these forward-looking statements are subject to known and unknown risks and uncertainties that may cause actual results to differ materially from those projected, expressed, or implied.

The factors that could cause actual results to differ materially from the forward-looking statements made by a registrant include (a) those factors discussed in the following sections of the Registrants' 2007 Annual Report on Form 10-K: ITEM 1A. Risk Factors and ITEM 7. Management's Discussion and Analysis of Financial Condition and Results of Operations as updated by Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations in this report, and (b) other factors discussed herein and in other filings with the SEC by the Registrants.

Readers are cautioned not to place undue reliance on these forward-looking statements, which apply only as of the date of this report. MGE Energy and MGE undertake no obligation to publicly release any revision to these forward-looking statements to reflect events or circumstances after the date of this report.

Investment in ATC - MGE Energy and MGE.

ATC owns and operates electric transmission facilities primarily in Wisconsin. MGE received an interest in ATC when it, like other Wisconsin electric utilities, contributed its electric transmission facilities to ATC. That interest is presently held by MGE Transco, which is jointly owned by MGE and MGE Energy.

MGE Transco, through MGE, has a seat on the Board of Directors of ATC and has a 20% ownership interest in ATC Management, Inc. Due to MGE Transco's ability to exercise significant control over management activities, MGE Transco has accounted for its investment in ATC under the equity method of accounting. For the six months ended June 30, 2008 and 2007, MGE Transco recorded equity earnings from the investment in ATC of $3.3 million (pretax) and $3.0 million (pretax), respectively. Dividend income received from ATC was $2.5 million and $2.1 million for the six months ended June 30, 2008 and 2007, respectively. During the six months ended June 30, 2008, MGE Transco made capital contributions of $1.3 million. During the six months ended June 30, 2007, MGE Transco made no cash contributions to ATC. However, on February 15, 2007, MGE (through MGE Transco) transferred $1.4 million in additional transmission assets to ATC. In exchange, MGE Transco received an additional $0.7 million investment in ATC and $0.7 million in cash consideration.

At June 30, 2008, MGE is the majority owner and MGE Energy, the holding company, is the minority owner of MGE Transco. MGE Energy's proportionate share of the equity and net income of MGE Transco is classified within the MGE financial statements as minority interest.

Taxes - MGE Energy and MGE.

FIN 48.

On January 1, 2007, MGE Energy and MGE adopted FIN 48, Accounting for Uncertainty in Income Taxes, an interpretation of SFAS No. 109, Accounting for Income Taxes. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements in accordance with SFAS No. 109. The interpretation applies to all tax positions accounted for in accordance with SFAS No. 109 and requires a recognition threshold and measurement standard for the financial statement recognition and measurement of a tax position taken, or expected to be taken, in an income tax return. FIN 48 defines the threshold for recognizing tax return positions in the financial statements as "more likely than not" that the position is sustainable, based on its merits. Subsequent recognition, derecognition, and measurement is based on management's best judgment given the facts, circumstances and information available at the reporting date.

For both MGE Energy and MGE, there have been no changes to unrecognized tax benefits existing at December 31, 2007, nor any additions for new tax positions, during the six months ended June 30, 2008. During the six months ended June 30, 2008, less than $0.1 million of interest was accrued on unrecognized tax benefits.

Effective Tax Rate.

MGE Energy's effective income tax rate for the three and six months ended June 30, 2008, is 36.0% and 35.7%, respectively, compared to 34.8% and 35.8% for the same periods in 2007. The decrease in the six months' rates is primarily attributable to an increase in federal tax credits from the production of electricity from wind energy, as a result of placing the Top of Iowa III wind project into production in February 2008.

MGE's effective income tax rate for the three and six months ended June 30, 2008, is 35.8% and 35.6%, respectively, compared to 34.7% and 35.7% for the same periods in 2007. The six months' decrease is also primarily attributable to an increase in wind energy tax credits.

Elm Road - MGE Energy and MGE.

Construction.

On November 4, 2005, MGE Power Elm Road acquired a 8.33% ownership interest in each of two 615 MW generating units being constructed in Oak Creek, Wisconsin (Oak Creek expansion). MGE Power Elm Road's sole principal asset is the 8.33% undivided ownership interest in the aforementioned coal-fired generating plants. The estimated share of capital costs for that ownership interest in both units was approximately $172 million (excluding capitalized interest). In July 2008, the Elm Road construction contractor gave notice that it now forecasts the in-service date of Unit 1 to be delayed by three months from the guaranteed in-service date of September 29, 2009 and that the in-service date of Unit 2 is now forecasted to be one month earlier than the guaranteed in-service date of September 29, 2010. The notice stated that the delays in Unit 1 were caused by severe weather, changes in local labor conditions from those anticipated by the contractor and other factors. The notice also stated that the contractor is analyzing the impacts of these events and expects to submit claims for schedule extensions and cost relief. The claims are expected to be submitted before December 31, 2008. At this time, because of the lack of information, the operator is not able to predict the amount of the claims that may be submitted, or the validity of such claims. However, the operator of the units has stated its belief that the circumstances and events for which they continue to retain price adjustment risk under the construction contract are force majeure, wage escalation in excess of 4% as measured by published wage bulletins, delays caused by the operator, requested change in scope or performance by the operator and unforeseen sub-surface ground conditions. Management is unable to determine the financial impact, if any, at this time.

At June 30, 2008, $130.5 million (excluding capitalized interest) related to this project is reflected in the construction work in progress balance on MGE's and MGE Energy's consolidated balance sheets. MGE Power Elm Road calculates capitalized interest in accordance with SFAS 34, Capitalization of Interest Cost, on the Elm Road project. At June 30, 2008, MGE Power Elm Road recorded a total of $8.4 million in capitalized interest related to the Elm Road project which is reflected in the construction work in progress balance on MGE's and MGE Energy's consolidated balance sheets.

Consolidation.

In connection with this project, MGE Energy and its subsidiaries entered into various agreements, including a facility lease agreement between MGE Power Elm Road (a nonregulated subsidiary of MGE Energy) and MGE. The financial terms of the facility lease include a capital structure of 55% equity and 45% long-term debt, and return on equity of 12.7%, a lease term of 30 years, and a 5% lease payment reduction in the first five years.

Based on the nature and terms of the leasing agreement and the relationship it establishes, MGE absorbs a majority of the expected losses, residual value, or both, associated with the ownership of MGE Power Elm Road. MGE also is the party most closely associated with MGE Power Elm Road. As a result, MGE is the primary beneficiary and MGE Power Elm Road is a VIE under FIN 46R. Accordingly, MGE Power Elm Road has been consolidated in the financial statements of MGE.

MGE Energy's share of the equity and net income (through its wholly owned subsidiary MGE Power) of MGE Power Elm Road is classified within the MGE financial statements as minority interest.

Nonregulated Revenues.

MGE has approval from the PSCW to defer the recovery of the payments made to MGE Power Elm Road for carrying costs during construction of the facility, management fees, and community impact mitigation costs. MGE estimates that the total carrying costs on the Elm Road project will be $60.7 million. This estimate is subject to change based on changes in interest rates, timing of capital expenditures, and the total project cost. During 2008, MGE will recover $12.1 million in electric rates for its investment in MGE Power Elm Road. Of this amount, $9.6 million relates to carrying costs and $2.5 million relates to management fees, community impact mitigation costs, and other related costs.

Page 15

MGE began collecting the carrying costs in rates in 2006. These amounts are being collected over multiple years. Of these costs, MGE estimates that $22.4 million relates to the capitalized interest and the debt portion of the facility. These costs will be recognized over the period in which the facility will be depreciated. The remaining $38.3 million is estimated to represent the equity portion and is being recognized over the period allowed for recovery in rates. For the six months ended June 30, 2008, $4.8 million related to the carrying costs were recovered in rates. Of this amount, $1.5 million relates to the debt portion of the facility and was deferred on the consolidated financial statements of MGE and MGE Energy. The remaining $3.3 million represents the equity portion and was recognized as nonregulated revenues in the consolidated financial statements of MGE and MGE Energy.

WPDES Permit.

On November 29, 2007, the Administrative Law Judge (the "ALJ") in the proceeding related to the previously issued Wisconsin Pollution Discharge Elimination System ("WPDES") permit determined that the two additional coal units that are part of the Oak Creek expansion are "new facilities" under section 316(b) of the Federal Clean Water Act. The ALJ did not vacate the WPDES permit or any other permit necessary to continue construction of the two additional coal units, pointing out that, based upon the present record, the water intake system currently under construction as part of the Oak Creek expansion may be permittable under the standards that apply to new facilities. The ALJ remanded the WPDES permit to the Wisconsin Department of Natural Resources (the "WDNR") and directed the WDNR to reissue or modify the permit to reflect "best technology available" to comply with the standards applicable to new facilities under Wisconsin state law. As part of the decision, the ALJ restated his prior opinion that the water intake system currently under construction may not be operated so long as it remains a contested matter.

The plant operator has advised us that there are alternatives under the United States Environmental Protection Agency's (the "EPA") rule for new facilities that would permit the use of the once-through cooling system rather than the use of cooling towers. The operator has requested the WDNR to issue a modified permit and has submitted additional information to the WDNR supporting the request for approval of the once-through cooling system under this rule.

On May 8, 2008, WDNR issued its public notice that it intended to reissue the WPDES permit to allow for the once-through cooling system that was under construction by Wisconsin Energy Corporation. On June 6, 2008, EPA issued its concurrence letter on the draft permit indicating it would not object to the modification of the WPDES permit as drafted. A public information hearing on the intended reissued WPDES permit was held on June 9, 2008 and the public comment period closed on June 16, 2008. On July 31, 2008, the WDNR issued the final modified permit, with no substantive changes from the previously issued draft permit. This permit can be challenged in a hearing before the Wisconsin Division of Hearings and Appeals or through judicial review.

On July 31, 2008, the joint owners of the Oak Creek expansion reached an agreement with Clean Wisconsin, Inc. and Sierra Club, the groups opposing the WPDES permit. Under the settlement agreement, these groups have agreed to withdraw their opposition to the modified WPDES permit for the expansion units at Oak Creek. The joint owners have committed to various environmental projects, including projects designed to address greenhouse gas emissions and water quality. MGE's share of those commitments would involve payments of approximately $0.2 million in each of 2008 and 2009 and, subject to regulatory approval, further payments of approximately $0.3 million annually over 25 years (2010-2035) to address water quality issues in Lake Michigan.

We cannot predict the timing or results, or the effect upon construction schedule or costs, of any decision by any administrative or legal process that may follow.

Top of Iowa III Wind Project - MGE Energy and MGE.

MGE has constructed a 29.7 MW (18 turbines) wind-powered electric generating facility in Iowa. In February 2008, the project was placed into service.

At June 30, 2008, MGE had incurred $56.4 million of costs on the project and $2.9 million in AFUDC, which are reflected in the property, plant, and equipment balance on MGE's and MGE Energy's consolidated balance sheets. During the six months ended June 30, 2008 and 2007, MGE had recorded $0.6 million and $0.5 million, respectively, in AFUDC related to this project. MGE was permitted to recover 100% AFUDC on the Top of Iowa III wind project during construction of the facility.

Expected Cash Flows.

There are no required contributions for the 2008 plan year. Likewise, there were no required contributions for the 2007 plan year. MGE elected to make discretionary deductible contributions of $6.5 million during the six months ended June 30, 2008. MGE may elect to make additional discretionary deductible contributions.

Pension Protection Act.

During the third quarter of 2006, President Bush signed into law the Pension Protection Act of 2006, which will affect the manner in which companies, including MGE and MGE Energy, administer their pension plans. This legislation will require companies to, amongst other things, increase the amount by which they fund their pension plans, pay higher premiums to the Pension Benefit Guaranty Corporation if they sponsor defined benefit plans, amend plan documents, and provide additional plan disclosures in regulatory filings and to plan participants. This legislation became effective on January 1, 2008. The U.S. Treasury Department's interim guidance indicates that further guidance is forthcoming. MGE does not expect significant changes in expected cash flows as a result of the Act. Absent changes in plan design as a result of the Act, the Act is not expected to materially impact MGE and MGE Energy's results of operations.

Page 17

Share-Based Compensation - MGE Energy and MGE.

The MGE Energy Board approved a Performance Unit Plan (the "Plan") on December 15, 2006. Under the Plan, eligible participants may receive performance units that entitle the holder to receive a cash payment equal to the value of a designated number of shares of MGE Energy's common stock, plus dividend equivalent payments thereon, at the end of the set performance period.

On January 1, 2007, the Board of Directors granted 22,479 units based on the MGE Energy December 31, 2006, closing stock price. On January 18, 2008, the Board of Directors granted 18,538 units based on the MGE Energy closing stock price as of that date. These units are subject to either a four or five year graded vesting schedule. Based on the provisions of SFAS 123R, Share-Based Payment, on the grant date, MGE Energy and MGE measured the cost of the employee services received in exchange for the award based on current market value of MGE Energy common stock. The fair value of the awards has been subsequently re-measured at June 30, 2008. Changes in fair value as well as the original grant have been recognized as compensation cost. Because this amount will be remeasured throughout the vesting period, the compensation cost is subject to variability.

For nonretirement eligible employees, stock based compensation costs are accrued and recognized using the graded vesting method. Pursuant to the provisions of SFAS 123R and the terms of the plan, compensation cost for retirement eligible employees or employees that will become retirement eligible during the vesting schedule, are recognized on an abridged horizon also using the graded vesting method.

During the six months ended June 30, 2008 and 2007, MGE recorded $0.2 million and $0.1 million, respectively, in compensation expense as a result of this plan. No forfeitures or cash settlements occurred during the aforementioned period.

Commitments and Contingencies.

Coal Contracts - MGE Energy and MGE.

Fuel procurement for MGE's jointly owned Columbia and Elm Road plants are handled by Alliant and Wisconsin Energy Corporation, respectively, the operating companies. If any minimum purchase obligations must be paid under these contracts, management believes these obligations would be considered costs of service and recoverable in rates. As of June 30, 2008, MGE's share of the total commitments for Columbia and Elm Road plants are estimated to be $8.7 million for the remainder of 2008, $19.1 million in 2009, $26.3 million in 2010, $5.4 million in 2011, and $4.4 million in 2012.

Natural Gas Supply Contracts - MGE Energy and MGE.

MGE has natural gas supply commitments which include market-based pricing. Total natural gas supply commitments are estimated to be $51.8 million for the remainder of 2008, $55.0 million for 2009, and $2.9 million for 2010. Management expects to recover these costs in future customer rates.

Environmental - MGE Energy and MGE.

MGE is listed as a potentially responsible party for a site the EPA has placed on the national priorities Superfund list. The Lenz Oil site in Lemont, Illinois, was used for storing and processing waste oil for several years. This site requires clean up under the Comprehensive Environmental Response, Compensation and Liability Act. A group of companies, including MGE, is currently working on cleaning up the site. Management believes that its share of the final cleanup costs will not result in any materially adverse effects on MGE's operations, cash flows, or financial position. Insurance may cover a portion of the cleanup costs. Management believes that the cleanup costs not covered by insurance will be recovered in current and future rates. At June 30, 2008, MGE accrued a $0.1 million gross liability for this matter. The expected range of loss for this item is estimated to be between $0.1 million and $0.2 million.

Effective March 31, 2006, Wisconsin adopted the Energy Efficiency and Renewables Act that focuses on three areas: increasing the use of renewable energy in Wisconsin, promoting the development of renewable energy technologies, and strengthening the state's energy efficiency programs. This new legislation requires that by 2015, 10% of the state's electricity be generated from renewable resources. As part of this initiative, MGE plans to add additional renewable energy resources, such as wind farms. MGE expects the cost to comply with the Act and its accompanying regulations will be recoverable through current and future rates.

Page 18

Air quality regulations promulgated by the EPA and WDNR in accordance with the Federal Clean Air Act and the Clean Air Act Amendments of 1990 impose restrictions on emission of particulates, sulfur dioxide (SO₂), nitrogen oxides (NO_x), and other pollutants and require permits for operation of emission sources. These permits have been obtained by MGE and must be renewed periodically.

On March 12, 2008, the U.S. EPA announced a new national ambient air quality standard for ozone which is more stringent than the current standard (standard lowered from 0.08 to 0.0750 parts per million). States (including Wisconsin) must monitor and collect data on ozone levels in order to determine attainment or nonattainment status on a county and/or area basis. Currently available monitoring data for Dane and Columbia counties demonstrates attainment with this new standard. However, final attainment designations will not be made until 2010 using the monitoring data collected during the period 2007 through 2009. There is a possibility that future monitoring data for one or both of these counties will demonstrate nonattainment for this new ozone standard, which could result in additional operating and capital expenditures at Columbia (located in Columbia county) and Blount (located in Dane county). Similarly, new standards for particulate emissions under 2.5 microns and monitoring data may result in a nonattainment designation for Dane county and possibly Columbia county for particulate emissions, which could also result in increased expenditures at Blount and Columbia.

Various initiatives including, but not limited to, the Clean Air Interstate Rule (CAIR), Clean Air Mercury Rule (CAMR), maximum achievable control technology (MACT) standards, new source performance standards (NSPS), Clean Air Visibility Rule (CAVR), the protection of visibility by application of best available retrofit technologies (BART), and existing and proposed state mercury emissions limits, are expected to result in significant additional operating and capital expenditures at Columbia, Elm Road, and Blount. There is some uncertainty concerning the mercury emission reduction requirements in light of a February 8, 2008, U.S. Court of Appeals decision vacating CAMR. Further, in February 2008, the WDNR proposed new revisions to the state mercury rules under NR 446 that are significantly different than CAMR and if finalized through state legislative review process, will further increase mercury control compliance costs at these facilities. There is also uncertainty concerning the NO_xand SO₂ emissions reduction requirements of CAIR in light of a July 11, 2008, U.S. Court of Appeals decision vacating CAIR.

In 1998, the EPA issued a rule that imposed NO_x emission budget for emission sources in Wisconsin. In 2000, the Court of Appeals for the District of Columbia invalidated a portion of the rule as applied to Wisconsin; however, the Court stayed that portion of the challenge concerning Wisconsin's alleged impacts on downwind, eight-hour ozone nonattainment areas. EPA has also stayed that portion of the rule concerning Wisconsin's alleged impacts on downwind eight-hour ozone nonattainment areas. If that portion of the rule concerning eight-hour ozone nonattainment areas is upheld, the resulting NO_x emission budget for Wisconsin could potentially affect the level of permissible NO_x emissions from Blount, Columbia, and WCCF.

The Columbia operator's current estimates show that MGE's share of the capital expenditures required to comply with various environmental initiatives will be between $130 million and $200 million. According to current estimates, compliance with various environmental initiatives is also expected to result in an increase to MGE's pro-rata share of Columbia's ongoing operating expenses. The operator and MGE management are continuing to explore various alternatives to comply with these standards. Accordingly, actual capital expenditures may fall above or below the range provided. These standards and initiatives may also result in additional capital and operating expenditures at MGE's other generating facilities. MGE expects that the costs to comply with these standards will be fully recoverable through rates. The PSCW is permitting MGE to defer pre-certification and pre-construction costs related to compliance with environmental regulations at Columbia. Additionally, MGE is entitled to a carrying cost on the related pre-construction costs at a 100% AFUDC rate. As of June 30, 2008, MGE had incurred $1.0 million (excluding carrying costs) in expenditures at Columbia related to environmental initiatives.

As of June 30, 2008, Columbia entered into various contractual commitments with vendors for a small portion of the aforementioned expenditures as well as other Columbia environmental projects. MGE is indirectly a party to these agreements as a result of its joint ownership of Columbia and is also contractually obligated, under the applicable ownership and operating agreements, with respect to any commitments made. MGE has a 22% ownership interest in Columbia. MGE's share of these commitments is estimated to be $0.6 million for the remainder of 2008. These costs are expected to be capitalized and included in the consolidated balance sheets of MGE Energy and MGE.

Chattel Paper Agreement and Other Guarantees - MGE Energy and MGE.

MGE makes available to qualifying customers a financing program for purchasing and installing energy-related equipment that will provide more efficient use of utility service at the customer's property. MGE is party to a chattel paper purchase agreement with a financial institution under which it can sell or finance an undivided interest with recourse, in up to $10.0 million of the financing program receivables, until August 31, 2008. At June 30, 2008, MGE had sold an outstanding $4.1 million interest in these receivables, which MGE accounted for as a sale under SFAS 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities - A Replacement of FASB Statement No. 125. MGE retains the servicing responsibility for these receivables.

On January 1, 2007, MGE adopted SFAS 156, Accounting for Servicing of Financial Assets, an amendment of SFAS 140. SFAS 156 clarified when to separately account for servicing rights, requires these rights to be initially measured at fair value, and provides the option to subsequently account for those servicing rights at either fair value or under the amortization method previously required under SFAS 140. MGE continues to account for servicing rights under the amortization method. Initial determination of the servicing asset fair value is based on the present value of the estimated future cash flows. The discount rate is based on the PSCW authorized weighted cost of capital.

MGE would be required to perform under its guarantee if a customer defaulted on its loan. The energy-related equipment installed at the customer sites is used to secure the customer loans. The loan balances outstanding at June 30, 2008, approximate the fair value of the energy-related equipment acting as collateral. The length of the MGE guarantee to the financial institution varies from one to ten years depending on the term of the customer loan. Principal payments for the next five years on the loans are $0.6 million in 2008, $0.6 million in 2009, $0.8 million in 2010, $0.5 million in 2011, and $0.3 million in 2012.

Other Legal Matters - MGE Energy and MGE.

MGE is involved in various other legal matters that are being defended and handled in the normal course of business. MGE maintains accruals for such costs that are probable of being incurred and subject to reasonable estimation. As of June 30, 2008, MGE has a total of $1.5 million accrued in the financial statements for such matters. The ultimate outcome of such matters is uncertain and may have an adverse effect on MGE's results of operations, financial position, and cash flows.

Venture Debt Commitment - MGE Energy.

MGE Energy has a three year agreement with a venture debt fund expiring in December 2010. MGE Energy has committed to this venture debt fund up to a total of $1.0 million at any given time. As of June 30, 2008, MGE Energy has $0.7 million remaining in commitments. The timing of infusions is dependent on the needs of the venture debt fund and is therefore uncertain at this time.

ATC Capital Commitment - MGE Energy and MGE.

On June 16, 2008, MGE Transco elected to participate in a voluntary capital call for ATC. As a result, MGE Transco contributed $1.1 million to ATC in July 2008.

Restructuring Activities - MGE Energy and MGE.

On January 19, 2006, MGE announced a plan, subject to certain conditions, that includes discontinuing coal use at the end of 2011 at Blount. The plant will continue to run on natural gas but will be reduced from its current approximate 190 MW capacity to 100 MW when coal burning is discontinued. MGE has determined that certain employee positions will be eliminated in 2011 as a result of this exit plan.

MGE has entered into severance agreements providing severance benefits to the nonunion employees affected by the exit plan. Additionally, MGE ratified a labor agreement with the IBEW providing those union employees affected by the exit plan with involuntary and voluntary severance benefits. MGE has accounted for the involuntary union and nonunion severance benefits in accordance with the provisions of SFAS 146, Accounting for Costs Associated with Exit or Disposal Activities. These benefits were recognized initially at the respective communication dates based on the fair value of the liability as of the termination date and are being recognized ratably over the future service period of the employees. Benefits are expected to be paid as follows: $0.2 million in 2010 and $1.2 million in 2011. Total benefits paid as of June 30, 2008 were $0.2 million.

Page 20

MGE will recover in rates the costs associated with the discontinuance of coal at Blount. As such, the severance charges for the nonunion and union employees have been deferred and recognized on the consolidated balance sheet of MGE Energy and MGE as a regulatory asset.

The following table presents the activity in the restructuring accrual from December 31, 2007, through June 30, 2008:

(In thousands)
Balance at December 31, 2007	$609
Additional expense, net (deferred)	106
Cash payments during the period	(149)
Balance at June 30, 2008	$566

The aforementioned exit plan has also resulted in accelerated depreciation for the Blount assets expected to be retired in 2011. These assets will be recovered in rates over a four year period starting in 2008. For the six months ended June 30, 2008, $1.7 million of accelerated depreciation expense had been recognized and recovered in rates.

12.

Derivative and Hedging Instruments - MGE Energy and MGE.

As part of its regular operations, MGE enters into contracts, including options, swaps, futures, forwards, and other contractual commitments, to manage its exposure to interest rates, commodity prices, and gas revenues. MGE evaluates its derivative contracts in accordance with SFAS 133, Accounting for Derivative Instruments and Hedging Activities, as amended and interpreted. To the extent that these contracts are derivatives, MGE assesses whether or not the normal purchases or normal sales exclusion applies. For contracts in which this exclusion cannot be applied, SFAS 133 requires MGE Energy and MGE to recognize such derivatives in the consolidated balance sheets at fair value, with changes in the fair value of derivative instruments to be recorded in current earnings or deferred in accumulated other comprehensive income (loss), depending on whether a derivative is designated as, and is effective as, a hedge and depending on the type of hedge transaction. If the derivative qualifies for regulatory deferral subject to the provisions of SFAS 71, Accounting for the Effects of Certain Types of Regulation, the derivatives are marked to fair value pursuant to SFAS 133 and are offset with a corresponding regulatory asset or liability.

In April 2007, the FASB issued FSP 39-1, Amendment of FASB Interpretation No. 39 (FSP FIN 39-1). This pronouncement amends FIN 39, Offsetting of Amounts Related to Certain Contracts, and allows companies to offset fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) against fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting agreement. MGE and MGE Energy elected the net presentation as prescribed by this pronouncement. FSP FIN 39-1 became effective for MGE and MGE Energy as of January 1, 2008. The effects of applying this pronouncement shall be recognized as a change in accounting principle through retroactive application for all financial statements presented. The adoption of this pronouncement did not have any impact on MGE's or MGE Energy's net income. At June 30, 2008, MGE Energy and MGE did not have any cash collateral to net against the net derivative positions with counterparties.

MGE's gas and electric segments purchased and sold exchange traded and over-the-counter options, swaps, and futures and, in addition, holds Financial Transmission Rights (FTRs) for certain transmission paths in the MISO market. At June 30, 2008, the net market value of all these aforementioned instruments exceeded their cost by $5.4 million.

MGE has also entered into a ten-year purchased power agreement which provides MGE with firm capacity and energy beginning June 12, 2012, and ending on May 31, 2022 (the "base term"). The agreement also allows MGE the option to purchase power during a period of time preceding the base term as well as an option to extend the contract after the base term. The agreement is a derivative contract and is recognized at its fair value on the balance sheet. The fair value of the contract at June 30, 2008, is $3.6 million. Also, the derivative qualifies for regulatory deferral and is recognized with a corresponding regulatory liability.

Under the PGA clause and electric fuel rules, MGE may include in costs of fuel (natural gas or power) the costs and benefits of the aforementioned fuel price risk management tools. Because these costs and benefits are recoverable, the related unrealized loss/gain is deferred on the balance sheet as a regulatory asset/liability. All of the instruments outstanding as of June 30, 2008, will expire in 12 months or less, except for the aforementioned ten-year purchased power agreement. Depending on the nature of the instrument, the gain or loss associated with these transactions will be reflected in natural gas purchased, purchased power, or fuel used for electric generation in the delivery month applicable to the instrument.

On September 26, 2007, MGE entered into a non-exchange traded HDD collar. This agreement extended from January 2008 until March 2008 and had a premium of $0.2 million. Under this agreement, MGE was subject to a floor (3,450 HDD) and a ceiling (3,600 HDD), based on forecasted heating degree days during the indicated period. If actual heating degree days were below the floor, MGE was entitled to receive a payment, and if actual heating degree days exceeded the ceiling, MGE was obligated to make a payment. Any payment or receipt was limited to $1.3 million. Actual heating degree days during the aforementioned period were 3,971. Because this number exceeded the ceiling, MGE recorded a $1.5 million expense (includes the $0.2 million premium) on the collar in the first quarter of 2008. MGE accounted for the HDD collar using the intrinsic value method pursuant to the requirements of EITF 99-2, Accounting for Weather Derivatives.

Nonperformance of counterparties to the non-exchange traded derivatives could expose MGE to credit loss. However, MGE enters into transactions only with companies that meet or exceed strict credit guidelines.

Regional Transmission Organizations - MGE Energy and MGE.

On April 1, 2005, the MISO implemented its bid-based energy market. MISO is a FERC approved RTO that is required to provide a real-time market based mechanism for congestion management. MGE is a participant in this market. On April 1, 2005, MGE began offering substantially all of its generation on the MISO market and purchasing much of its load requirement from the MISO market in accordance with the MISO Tariff.

Additionally, on May 1, 2004, MGE became a member of PJM. PJM is also an RTO. PJM is a neutral and independent party that coordinates and directs the operation of the region's transmission grid, administers a competitive wholesale electricity market, and plans regional transmission expansion improvements to maintain grid reliability and relieve congestion. MGE has two purchase power agreements, for a total of 65 MW, that are affected by this market.

MGE reports on a net basis transactions on the MISO and PJM markets in which it buys and sells power within the same hour to meet electric energy delivery requirements. This treatment resulted in $40.3 million and $37.6 million reduction to sales for resale and purchased power expense for the three months ended June 30, 2008 and 2007, respectively, and an $82.5 million and $78.4 million reduction to sales for resale and purchased power expense for the six months ended June 30, 2008 and 2007, respectively.

Rate Matters - MGE Energy and MGE.

Rate proceedings.

On May 30, 2008, MGE filed with the PSCW a limited scope reopener of its 2009 electric rates. The application included an update to MGE's electric fuel costs monitored under the fuel rules and an update to the Elm Road costs. If approved by the PSCW, the net effect of the requested changes would result in a 6.99% increase, on average, in retail electric rates.

On December 14, 2007, the PSCW authorized MGE to increase 2008 electric rates by 4.8% or $16.2 million and increase gas rates by 2.8% or $7.8 million. The electric increase will cover costs for MGE's new wind energy projects, statewide energy efficiency and renewable energy programs, transmission improvements by ATC, and accelerated costs to discontinue coal use at the Blount Station. In addition to funding the statewide energy programs, the natural gas rate increase covered costs for area gas construction projects needed to accommodate customer growth. Authorized return on common stock equity was set at 10.8% based on 57.4% utility common equity.

Pursuant to the provisions of this rate order, the fuel rules bandwidth effective January 1, 2008, is plus or minus 2%. See description of fuel rules below.

Page 22

On December 22, 2006, the PSCW approved a limited scope rate case reopener related to MGE's current electric rates. This order approved an update to MGE's electric fuel costs monitored under the fuel rules, an updated estimate of the 2007 Elm Road carrying costs, and a request for recovery of increased ATC-related transmission costs through December 31, 2007. This order resulted in a net 0.15% decrease, on average, in retail electric rates for 2007. The PSCW also approved the recovery of 100% AFUDC on the Top of Iowa III wind project beginning in November 2006 and continuing until construction on the project ceased.

Fuel rules.

Actual electric fuel costs are subject to reconciliation to the amount approved by the PSCW in MGE's rate order covering the applicable period. Known as "fuel rules," the process can produce a fuel surcharge for MGE or require MGE to make a refund in the form of a credit, to the extent that the actual fuel costs are outside a range higher or lower than the level authorized by the PSCW in that rate order.

Under fuel rules effective January 1, 2008, MGE can apply for a fuel surcharge if its actual electric fuel costs exceed 102% of the electric fuel costs allowed in its latest rate order. Conversely, MGE can be required to provide a fuel credit to its customers if actual electric fuel costs are less than 98% of the electric fuel costs allowed in that order.

The PSCW approved a $0.00239 per kWh interim fuel surcharge on MGE's electric rates effective May 6, 2008, to cover increased fuel and purchased power expenses. This interim fuel surcharge will result in an estimated $8.0 million increase in electric revenues on an annual basis. For the three and six months ended June 30, 2008, this interim surcharge resulted in a $1.2 million increase to electric rates. However, pursuant to the provisions of this interim order, MGE's electric revenues resulting from this interim surcharge are subject to refund with interest at 10.8% should it ultimately be determined that the interim fuel surcharge resulted in collections greater than actual costs. No amount was estimated to be refunded under these provisions at June 30, 2008.

On April 26, 2007, the PSCW approved a $0.00339 per kWh interim fuel surcharge on MGE's electric rates to cover increased fuel and purchased power expenses. On August 31, 2007, MGE received a final decision which reduced the fuel surcharge from $0.00339 per kWh to $0.00242 per kWh. These surcharges resulted in a gross increase to electric rates of $6.9 million for the twelve months ended December 31, 2007. For the interim period April 26, 2007, through August 31, 2007, the difference between the interim surcharge and the final surcharge was required to be refunded to customers. Accordingly, on October 6, 2007, a refund of $1.3 million was applied to customers' accounts.

As a result of a decrease in electric fuel costs during the twelve months ended December 31, 2006, a fuel credit was approved by the PSCW. To account for this credit, MGE recorded a $19.1 million reduction to other electric revenues. During the year ended December 31, 2006, $16.8 million had been credited to electric customers. An additional $2.4 million (includes interest) was applied to customers' accounts in April 2007.

SFAS 157 Fair Value of Assets and Liabilities - MGE Energy and MGE.

As of January 1, 2008, MGE and MGE Energy adopted SFAS 157, Fair Value Measurements. The adoption of this standard requires enhanced disclosures about MGE's and MGE Energy's assets and liabilities carried at fair value.

SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The standard clarifies that fair value should be based on the assumptions market participants would use when pricing the asset or liability including assumptions about risk. The standard also establishes a three level fair value hierarchy based upon the observability of the assumptions used and requires the use of observable market data when available. The levels are:

Level 1 - Pricing inputs are quoted prices within active markets for identical assets or liabilities.

Level 2 - Pricing inputs are quoted prices within active markets for similar assets or liabilities; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations that are correlated with or otherwise verifiable by observable market data.

Page 23

Level 3 - Pricing inputs are unobservable and reflect management's best estimate of what market participants would use in pricing the asset or liability.

In February 2008, the FASB issued FSP FAS 157-2, Effective Date of FASB Statement No. 157, which delays the effective date of SFAS 157 for all nonrecurring fair value measurements of nonfinancial assets and liabilities until fiscal years beginning after November 15, 2008. MGE Energy and MGE have elected to defer the adoption of the nonrecurring fair value measurement disclosures of nonfinancial assets and liabilities. The adoption of FSP FAS 157-2, effective January 1, 2009, is not expected to have any material impact on MGE Energy and MGE.

The following table presents the balances of assets and liabilities measured at fair value on a recurring basis for MGE Energy and MGE.

(In thousands)	Fair Value as of June 30, 2008
	Total	Level 1	Level 2	Level 3

Liabilities:
Deferred compensation	$1,083	$1,083	$-	$-
Total Liabilities	$1,083	$1,083	$-	$-

Derivatives include exchange-traded derivative contracts, a ten-year purchased power agreement, and FTRs. Most exchange-traded derivative contracts are valued based on unadjusted quoted prices in active markets and are therefore classified as Level 1. A small number of exchange-traded contracts are valued using quoted market pricing in markets with insufficient volumes and are therefore classified as Level 3. The ten-year purchased power agreement (see Footnote 12) was valued using an internally-developed pricing model and therefore classified as Level 3. The model includes both observable and unobservable inputs. FTRs are priced based upon monthly auction results for identical or similar instruments in a closed market with limited data available and are therefore classified as Level 3.

Investments include exchange-traded investment securities valued using quoted prices on active exchanges and are therefore classified as Level 1.

The deferred compensation plan allows participants to defer certain cash compensation into a notional investment account. These amounts are included within other deferred liabilities in the balance sheets of MGE Energy and MGE. The notional investments earn interest based upon the semiannual rate of U.S. Treasury Bills having a 26 week maturity increased by 1% compounded monthly, with a minimum annual rate of 7%, compounded monthly, and are therefore based upon observable market data and classified as Level 1.

(a) MGE's exchange-traded derivative contracts, ten-year purchased power agreement, and FTRs are subject to regulatory deferral under the provisions of SFAS 71. These derivatives are therefore marked to fair value pursuant to SFAS 133 and are offset with a corresponding regulatory asset or liability. A portion of MGE's derivative contracts fall under the incentive mechanism within the PGA clause and shareholders have the ability to receive 50% of the benefit or loss from these deals if certain thresholds are achieved. Under these derivatives, only 50% of the gains or losses are subject to regulatory deferral under SFAS 71. The remaining 50%, the shareholder portion, is reflected in other comprehensive income. As a result of the above described treatment, there are no unrealized gains or losses that flow through earnings.

New Accounting Pronouncements and Legislation - MGE Energy and MGE.

Pension Protection Act.

See Footnote 8 for discussion of this pronouncement.

FSP FIN 39-1.

See Footnote 12 for discussion of this pronouncement.

FAS 160 and FAS 141(R).

In December 2007, the FASB issued FAS 160, Non-Controlling Interests in Consolidated Financial Statements, an amendment of ARB No. 51 and FAS 141(R), Business Combinations. These pronouncements will change the accounting and reporting for business acquisitions and non-controlling interest in a subsidiary. In addition, FAS 160 will change the accounting and reporting for the deconsolidation of a subsidiary. FAS 160 and FAS 141(R) will be effective for MGE and MGE Energy as of January 1, 2009. MGE and MGE Energy are currently assessing the impact these pronouncements will have on their financial statements.

FAS 161.

In March 2008, the FASB issued FAS 161, Disclosures about Derivative Instruments and Hedging Activities. The new standard is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity's financial position, financial performance, and cash flows. It is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early adoption allowed. MGE and MGE Energy have elected not to early adopt this pronouncement. Therefore, FAS 161 will be effective for MGE and MGE Energy as of January 1, 2009. MGE and MGE Energy are currently assessing the impact this pronouncement will have on their financial statements.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

General

MGE Energy is a holding company operating through subsidiaries in five business segments: electric utility operations, gas utility operations, nonregulated energy operations, transmission investments, and all other. Our principal subsidiary is MGE, which conducts our electric utility and gas utility operations. MGE generates and distributes electricity to nearly 136,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and distributes natural gas to nearly 140,000 customers in the Wisconsin counties of Columbia, Crawford, Dane, Iowa, Juneau, Monroe, and Vernon.

Our nonregulated energy operations have been formed to own, for lease to MGE, new electric generating capacity. Our nonregulated energy operations include a cogeneration project on the UW-Madison campus. Our nonregulated energy operations also include an undivided 8.33% ownership interest in each of two 615 MW generating units being constructed in Oak Creek, Wisconsin. All of these operations are included in MGE's consolidated financial statements as a result of the accounting requirements of FIN 46R, Consolidation of Variable Interest Entities - An Interpretation of ARB No. 51.

The transmission investment segment consists of our investment in ATC. Our all other segment includes corporate operations and services and certain construction services.

Our primary focus today and for the foreseeable future is our core utility customers at MGE. MGE continues to face the challenge of providing its customers with reliable power at competitive prices. MGE plans to meet this challenge by building more efficient generation projects and continuing its efforts to control operational costs. We believe it is critical to maintain a strong credit standing and financial strength for MGE as well as for the parent company in order to accomplish these goals.

Three Months Ended June 30, 2008 and 2007

Executive Summary - MGE Energy and MGE

For the three months ended June 30, 2008, MGE Energy's earnings were $10.6 million or $0.48 per share compared to $10.0 million or $0.47 per share for the same period in the prior year. MGE's earnings for the three months ended June 30, 2008, were $7.2 million compared to $7.0 million for the same period in the prior year.

The following discussion is based on the business segments as discussed in Footnote 17.

Electric Utility

The electric utility segment contributed $7.2 million of net income during the second quarter of 2008, a slight increase of $0.1 million compared to the second quarter of 2007.

Electric revenues were $3.1 million or 3.8% higher during the second quarter of 2008 compared to the same period last year. The increase is partially related to a 4.8% rate increase approved by the PSCW, effective January 1, 2008. The rate increase was to cover higher costs pertaining to MGE's new wind energy projects, statewide energy efficiency and renewable energy programs, transmission improvements by ATC, and accelerated costs associated with the discontinued use of coal at the Blount Station. Also contributing to the electric revenue increase was an interim fuel surcharge, which was a result of higher fuel costs than those costs provided in the applicable rate order. The PSCW approved a $0.00239 per kWh interim fuel surcharge on MGE's electric rates effective May 6, 2008, which resulted in $1.2 million being collected during the three months ended June 30, 2008.

Gas Utility

The gas utility segment recorded a $0.5 million net loss during the second quarter of 2008 which is comparable to the second quarter of 2007. Gas margin (regulated gas revenues less natural gas purchased) increased $2.2 million during the second quarter of 2008 compared to the same period last year. MGE received a 2.8% rate increase from the PSCW, effective January 1, 2008, to cover costs for area gas construction projects needed to accommodate growth and funding of statewide energy efficiency and renewable energy programs. Compared to the prior period, gas operating and maintenance expenses increased $1.6 million primarily related to payments required to be made to statewide energy efficiency and renewable resource programs pursuant to Wisconsin legislation.

Page 30

Gas margin (regulated gas revenues less natural gas purchased) is not a measurement defined under GAAP. MGE Energy and MGE believe this measurement is useful in analyzing the gas utility segment. However, it may not be comparable to measurements of other companies. In addition, this measurement may not be more useful than the GAAP information regarding the gas utility segment provided elsewhere in this report.

Nonregulated Energy

The nonregulated energy segment contributed $2.5 million of net income during the second quarter of 2008, an increase of $0.3 million or 12.9% compared to the second quarter of 2007. The increase is largely attributable to higher carrying costs recognized for the Elm Road project. Carrying costs during construction of the nonregulated energy projects, related to the equity portion, are recognized over the period of time the costs are recovered in rates.

Capital expenditures during the second quarter of 2008 totaled $14.9 million for the Elm Road project.

Transmission Investment

Earnings from our interest in ATC increased $0.1 million for the second quarter of 2008 compared to the same period last year.

MGE Transco contributed $1.3 million for a voluntary capital contribution to ATC in April 2008 and an additional $1.1 million voluntary capital contribution in July 2008. ATC may request additional voluntary capital contributions from the owners during 2008 and MGE Transco plans to participate in those contributions.

All Others

MGE Energy's corporate operations contributed $0.3 million in earnings for the second quarter of 2008. These earnings are a result of interdepartmental interest income recognized as a result of capitalized interest on the Elm Road project.

(In millions)	Three Months Ended June 30, 2008
Rate changes	$6.6
Volume	(0.8)
Sales for resale	(0.4)
Other revenues	(2.3)
Total	$3.1

•

Rates changes. Rates charged to retail customers for the three months ended June 30, 2008, were 8.4% or $6.6 million higher than those charged during the same period in the prior year.

Page 31

On December 14, 2007, the PSCW authorized MGE to increase 2008 electric revenue by $16.2 million to cover costs for MGE's new wind energy projects, statewide energy efficiency and renewable energy programs, transmission improvements by ATC, and accelerated costs to discontinue coal use at the Blount Station.

On May 5, 2008, the PSCW approved a $0.00239 per kWh interim fuel surcharge on MGE's electric rates to cover increased fuel and purchased power expenses. This interim fuel surcharge will result in an estimated $8.0 million increase in electric revenues on an annual basis. The interim fuel surcharge was included in electric rates as of May 6, 2008. For the three months ended June 30, 2008, this interim surcharge resulted in a $1.2 million increase to electric rates. However, pursuant to the provisions of this interim order, MGE's electric revenues resulting from this interim surcharge are subject to refund with interest at 10.8% should it ultimately be determined that the interim fuel surcharge resulted in collections greater than actual costs. No amount was estimated to be refunded under these provisions at June 30, 2008.

On April 24, 2007, when the PSCW completed their audit of 2006 electric fuel costs and issued a final order on the 2006 fuel credit, $2.4 million (related to 2006 fuel costs and including interest) was applied to customers' accounts.

On April 26, 2007, a $0.00339 per kWh interim fuel surcharge, subject to refund, was approved by the PSCW which resulted in a $2.0 million increase to electric rates charged to customers during the three months ended June 30, 2007.

•

Volume. During the three months ended June 30, 2008, there was a 0.9% decrease in total retail sales volumes when compared to the same period in the prior year. This decrease represents decreased usage by residential and commercial customers, offset by an increase in usage from industrial and other-retail/municipal customers.

•

Sales for resale. For the three months ended June 30, 2008, sales for resale decreased $0.4 million when compared to the same period in the prior year, reflecting a decreased volume of sales. Sales for resale include transactions conducted on the PJM and MISO markets reflecting our involvement in the PJM and MISO markets since their establishment on May 1, 2004, and April 1, 2005, respectively.

•

Other revenues. Other electric revenues decreased $2.3 million for the three months ended June 30, 2008, compared to the same period in the prior year.

During the three months ended June 30, 2008 and 2007, MGE recovered in electric rates carrying costs and other fees related to WCCF and Elm Road. During the three months ended June 30, 2008 and 2007, MGE recorded a $2.8 million and $2.1 million reduction, respectively, to other electric revenues to transfer the revenues from the electric segment to the nonregulated energy operations segment. See discussion of these revenues in the "nonregulated energy operating revenues" section.

During the three months ended June 30, 2007, other electric revenues included a $2.4 million upward adjustment to negate the impact on overall electric revenues for the 2006 fuel refund provided to customers in April 2007. Note that this refund was accrued in revenues during 2006, and was returned to customers via a reduction in rates in April 2007. See "Rate changes" above for more information on this refund. Furthermore, to account for the subject to refund provisions implemented by the PSCW on April 26, 2007, during the three months ended June 30, 2007, MGE recognized an obligation to make refunds to its customers by recording a $0.6 million reduction to other electric revenues.

Other miscellaneous electric revenues for the three months ended June 30, 2008 increased $0.2 million compared to the same period in 2007.

Electric fuel and purchased power

The expense for fuel used for electric generation decreased $0.7 million or 5.3% during the three months ended June 30, 2008, compared to the same period in the prior year primarily as a result of a decrease in fuel costs.

Purchased power expense decreased by $4.0 million or 21.4% during the three months ended June 30, 2008, compared to the same period in the prior year. This decrease in expense reflects a $3.2 million or 17.4% decrease in the per unit cost of purchased power and a $0.8 million or 4.8% decrease in the volume of power purchased.

Page 32

Electric operating expenses

Electric operating expenses increased $2.9 million during the three months ended June 30, 2008, compared to the same period in 2007. The following changes contributed to the net change:

(In millions)	Three Months Ended June 30, 2008
Increased production costs	$0.4
Increased transmission costs	0.6
Increased distribution expenses	0.2
Decreased customer accounts expenses	(0.2)
Increased customer service costs	1.1
Decreased sales promotion expenses	(0.1)
Increased other general and administrative expenses	0.9
Total	$2.9

As a result of the 2005 Wisconsin Act 141, each Wisconsin utility is required to pay 1.2% of its annual operating revenues to the statewide energy efficiency and renewable resource programs. MGE is allowed to recover these costs in rates through its conservation escrow. For the three months ended June 30, 2008, costs associated with funding these programs increased customer service expense by $1.3 million.

Electric maintenance expense

For the three months ended June 30, 2008, electric maintenance expense increased $2.3 million, when compared to the same period in the prior year. This increase is attributable to increases of $1.8 million in production maintenance and $0.5 million in distribution expenses.

Electric depreciation expense

Depreciation expense at the electric segment increased by $1.7 million for the three months ended June 30, 2008, when compared to the same period in the prior year. This increase is related to higher levels of electric assets, including the Top of Iowa III wind-powered electric generating facility which was placed in service in the first quarter of 2008. Also contributing to the increase is the accelerated depreciation of certain Blount assets. For additional information on the Blount accelerated depreciation, see Footnote 11.

Average rate per therm of retail customer				$1.376	$1.137	21.0%

Page 33

Gas revenues increased $10.6 million or 37.5% for the three months ended June 30, 2008. These changes are related to the following factors:

(In millions)	Three Months Ended June 30, 2008
Gas costs/rates	$5.7
Gas deliveries	4.2
Transportation and other effects	0.7
Total	$10.6

•

Gas costs/rates. The average retail rate per therm for the three months ended June 30, 2008, increased 21.0% compared to the same period in 2007. The primary contributor to this increase is higher natural gas costs.

Also, the PSCW authorized a 2.8% increase in MGE's gas rates effective January 1, 2008, to cover increased system demands and funding statewide energy programs.

•

Retail gas deliveries. The 12.7% increase in retail gas deliveries for the three months ended June 30, 2008, was attributable to an 11.7% increase in the heating degree days between the periods and increased use by a large commercial customer.

•

Transportation and other revenues. Transportation and other revenues increased a total of $0.7 million primarily due to an increase in income realized under the GCIM.

Under MGE's GCIM, if actual gas commodity costs are above or below a benchmark set by the PSCW, then MGE's gas sales service customers and shareholders share equally in any increased costs or savings. The PSCW also allows MGE to resell gas pipeline capacity reserved to meet peak demands but not needed every day to serve customers. Revenues from capacity release that exceed or fall short of PSCW-targeted levels are shared equally. For the three months ended June 30, 2008 and 2007, shareholders received the benefit of $1.1 million and $0.4 million, respectively, from capacity release revenues and commodity savings under the GCIM.

Natural gas purchased

For the three months ended June 30, 2008, natural gas purchased increased by $8.5 million, compared to the same period in the prior year. The cost per therm of natural gas increased 31.4% which resulted in $6.3 million of additional expense. In addition, an 11.9% increase in the volume of gas purchased resulted in $2.2 million of additional expense.

Gas operating expenses

Gas operating expenses increased $1.4 million for the three months ended June 30, 2008, compared to the same period a year ago. The following changes contributed to the net change:

(In millions)	Three Months Ended June 30, 2008
Increased distribution costs	$0.2
Increased customer service costs	0.8
Increased general and administrative costs	0.4
Total	$1.4

Gas maintenance expense

Gas maintenance expenses increased by $0.2 million for the three months ended June 30, 2008, compared to the same period in the prior year. This increase relates to an increase in distribution costs.

Executive Summary - MGE Energy and MGE

For the six months ended June 30, 2008, MGE Energy's earnings were $24.4 million or $1.11 per share compared to $22.3 million or $1.05 per share for the same period in the prior year. MGE's earnings for the six months ended June 30, 2008, were $17.6 million compared to $16.4 million for the same period in the prior year.

The following discussion is based on the business segments as discussed in Footnote 17.

Page 36

Electric Utility

The electric utility segment contributed $9.3 million of net income during the six months ended June 30, 2008, a slight decrease of $0.3 million compared to the same period in 2007.

•

Electric revenues were $8.8 million or 5.6% higher during the six months ended June 30, 2008 compared to the same period last year. The increase is a result of a 0.5% increase in retail sales and a 4.8% rate increase approved by the PSCW, effective January 1, 2008. The rate increase was to cover higher costs pertaining to MGE's new wind energy projects, statewide energy efficiency and renewable energy programs, transmission improvements by ATC, and accelerated costs associated with the discontinued use of coal at the Blount Station. Also contributing to the electric revenue increase was an interim fuel surcharge, which was a result of higher fuel costs than those costs provided in the applicable rate order. The PSCW approved a $0.00239 per kWh interim fuel surcharge on MGE's electric rates effective May 6, 2008 which resulted in $1.2 million being collected during the six months ended June 30, 2008.

•

The Top of Iowa III construction project was placed in service during the first quarter of 2008. As of June 30, 2008, MGE has incurred $56.4 million of costs on the 29.7 MW wind-powered electric generating facility located in Iowa. MGE recorded $0.6 million of AFUDC in the six months ended June 30, 2008 related to the construction of the project.

Gas Utility

The gas utility segment contributed $7.3 million of net income during the six months ended June 30, 2008, an increase of $1.1 million or 17.8% compared to the same period in 2007. The increase is largely attributable to higher gas margins as a result of colder weather compared to the same period in 2007. Gas margin (regulated gas revenues less natural gas purchased) increased $7.2 million during the six months ended June 30, 2008 compared to the same period last year. The increase was primarily attributable to 12.9% increase in gas retail sales. Heating degree days were 12.1% higher for the period compared to last year as a result of colder weather. MGE also received a 2.8% rate increase from the PSCW, effective January 1, 2008, to cover costs for area gas construction projects needed to accommodate growth and funding of statewide energy efficiency and renewable energy programs. Partially offsetting the higher margin was a $1.3 million expense (excludes premium) in 2008 for a weather hedge (heating degree day collar). The weather hedge obligated MGE to pay additional costs if the weather was colder than a prescribed ceiling or would have compensated MGE if weather was warmer than a prescribed floor.

Nonregulated Energy

The nonregulated energy segment contributed $5.1 million of net income during the six months ended June 30, 2008, an increase of $0.8 million or 17.5% compared to the same period in 2007. The increase is largely attributable to higher carrying costs recognized for the Elm Road project. Carrying costs during construction of the nonregulated energy projects, related to the equity portion, are recognized over the period of time the costs are recovered in rates.

Capital expenditures during the six months ended June 30, 2008 totaled $30.5 million for the Elm Road project.

Transmission Investment

Earnings from our interest in ATC increased $0.2 million for the six months ended June 30, 2008 compared to the same period last year.

All Others

MGE Energy's corporate operations contributed $0.7 million in earnings for the six months ended June 30, 2008. These earnings are a result of interdepartmental interest income recognized as a result of capitalized interest on the Elm Road project.

Total	$8.8

•

Rates changes. Rates charged to retail customers for the six months ended June 30, 2008, were 7.8% or $12.2 million higher than those charged during the same period in the prior year.

On May 5, 2008, the PSCW approved a $0.00239 per kWh interim fuel surcharge on MGE's electric rates to cover increased fuel and purchased power expenses. This interim fuel surcharge will result in an estimated $8.0 million increase in electric revenues on an annual basis. The interim fuel surcharge was included in electric rates as of May 6, 2008. During the six months ended June 30, 2008, this surcharge resulted in $1.2 million increase to electric rates. However, pursuant to the provisions of this interim order, MGE's electric revenues resulting from this interim fuel surcharge are subject to refund with interest at 10.8% should it ultimately be determined that the interim fuel surcharge resulted in collections greater than actual costs. No amount was estimated to be refunded under these provisions at June 30, 2008.

On April 26, 2007, a $0.00339 per kWh fuel surcharge, subject to refund, was approved by the PSCW which resulted in a $2.0 million increase to electric rates charged to customers during the three months ended June 30, 2007.

•

Volume. During the six months ended June 30, 2008, there was a 0.5% increase in total retail sales volumes when compared to the same period in the prior year. This increase represents higher usage by commercial customers and other-retail/municipal customers, offset by a decline in residential and industrial usage.

Page 38

•

Sales for resale. For the six months ended June 30, 2008, sales for resale decreased $1.2 million when compared to the same period in the prior year, reflecting a decreased volume of sales. Sales for resale include transactions conducted on the PJM and MISO markets reflecting our involvement in the PJM and MISO markets since their establishment on May 1, 2004, and April 1, 2005, respectively.

•

Other revenues. Other electric revenues decreased $3.0 million for the six months ended June 30, 2008, compared to the same period in the prior year.

During the six months ended June 30, 2008 and 2007, MGE recovered in electric rates carrying costs and other fees related to WCCF and Elm Road. During the six months ended June 30, 2008 and 2007, MGE recorded a $5.5 million and $4.1 million reduction, respectively, to other electric revenues to transfer the revenues from the electric segment to the nonregulated energy operations segment. See discussion of these revenues in the "nonregulated energy operating revenues" section.

During the six months ended June 30, 2007, other electric revenues included a $2.4 million upward adjustment to negate the impact on overall electric revenues for the 2006 fuel refund provided to customers in April 2007. Note that this refund was accrued in revenues during 2006, and was returned to customers via a reduction in rates in April 2007. See "Rate changes" above for more information on this refund. Furthermore, to account for the subject to refund provisions implemented by the PSCW on April 26, 2007, during the three months ended June 30, 2007, MGE recognized an obligation to make refunds to its customers by recording a $0.6 million reduction to other electric revenues.

Other miscellaneous electric revenues for the six months ended June 30, 2008, increased $0.2 million compared to the same period during the prior year.

Electric fuel and purchased power

The expense for fuel used for electric generation increased $1.7 million or 6.3% during the six months ended June 30, 2008, compared to the same period in the prior year. Additional internal generation resulted in a $0.4 million increase of this expense and increased fuel costs between the two periods resulted in a $1.3 million increase of this expense.

Purchased power expense decreased by $3.8 million or 9.4% during the six months ended June 30, 2008, compared to the same period in the prior year. This decrease in expense reflects a $2.2 million or 5.4% decrease in the per unit cost of purchased power and a $1.6 million or 4.2% decrease in the volume of power purchased.

Electric operating expenses

Electric operating expenses increased $6.2 million during the six months ended June 30, 2008, compared to the same period in 2007. The following changes contributed to the net change:

Consolidated Other General Taxes

MGE Energy's and MGE's other general taxes increased $0.8 million or 9.6% for the six months ended June 30, 2008, when compared to the same period in 2007, due to a combination of two factors affecting the MGE license fee tax, which is a tax levied on gross sales in lieu of property tax on utility property. First, higher sales increased the 2008 tax compared to the 2007 tax. Secondly, the license fee tax for 2007 was reduced by an audit settlement, achieved in March 2007, involving prior years' license fee tax.

Consolidated Income Taxes

MGE Energy's effective income tax rate for the six months ended June 30, 2008, is 35.7% compared to 35.8% for the same period in 2007. This decrease is primarily attributable to an increased federal tax credit for production of electricity from wind energy, as a result of placing the Top of Iowa III wind project into production in February 2008. Electricity generated from wind energy produces a 2.1 cents per kilowatt hour federal tax credit. The Top of Iowa III wind project will substantially increase the wind energy tax credit for 2008.

MGE's effective income tax rate for the six months ended June 30, 2008, is 35.6% compared to 35.7% for the same period in the prior year. The decrease is also primarily attributable to the increased wind energy tax credit.

For the six months ended June 30, 2007, MGE Energy (through its wholly owned subsidiary MGE Power) had earned $3.9 million and $1.3 million, net of tax, for its interest in MGE Power West Campus and MGE Power Elm Road, respectively. Additionally, MGE Energy had earned $0.3 million, net of tax, for its interest in MGE Transco. These amounts are recorded as minority interest expense, net of tax, on MGE's consolidated statement of income.

Contractual Obligations and Commercial Commitments - MGE Energy and MGE

Columbia Environmental Matters - MGE Energy and MGE.

As of June 30, 2008, Columbia entered into various contractual commitments with vendors for a small portion of the environmental expenditures. MGE is indirectly a party to these agreements as a result of its joint ownership of Columbia and is also contractually obligated, under the applicable ownership and operating agreements, with respect to any commitments made. MGE's share of these commitments is estimated to be $0.6 million for the remainder of 2008. These costs are expected to be capitalized and included in the consolidated balance sheet of MGE. See "Environmental Matters - Columbia" below for additional information.

Elm Road Construction - MGE Energy and MGE.

In July 2008, Bechtel, the Elm Road construction contractor, gave notice that it now forecasts the in-service date of Unit 1 to be delayed three months beyond the guaranteed contract date of September 29, 2009. Bechtel also advised that it now forecasts the in-service date of Unit 2 to be one month earlier than the guaranteed contract date of September 29, 2010.

Bechtel states that reasons for the delay of Unit 1 include severe winter weather experienced during the winters of 2006-2007 and 2007-2008, exacerbated by severe rain storms in April and June of 2008, changes in local labor conditions from those anticipated by Bechtel, the cumulative impact of a large number of change orders and delay in receiving full notice to proceed in 2005 (which was a result of the court challenges by certain opposition groups to the Certificate of Public Convenience and Necessity for the Oak Creek expansion).

Bechtel's notice indicates that it is still analyzing the impact of these events, and that it expects to submit claims for schedule extensions and cost relief with required justification by the end of 2008. These claims will be reviewed when they arrive to determine if Bechtel is entitled to any schedule and/or cost relief.

The operator of the units has stated its belief that the circumstances and events for which they continue to retain price adjustment risk under the construction contract are force majeure, wage escalation in excess of 4% as measured by published wage bulletins, delays caused by the operator, requested change in scope or performance by the operator and unforeseen sub-surface ground conditions. Management is unable to determine the financial impact, if any, at this time.

Other Legal Matters - MGE Energy and MGE.

MGE is involved in various other legal matters that are being defended and handled in the normal course of business. MGE maintains accruals for such costs that are probable of being incurred and subject to reasonable estimation. At June 30, 2008, MGE has a total of $1.5 million accrued in the financial statements for such matters. The ultimate outcome of such matters is uncertain and may have an adverse effect on MGE's results of operations or cash flows.

WPDES Settlement Agreement Contracts - MGE Energy and MGE.

On July 31, 2008, the joint owners of the Oak Creek expansion reached an agreement with Clean Wisconsin, Inc. and Sierra Club, the groups opposing the WPDES permit. As part of this settlement, MGE has committed to make approximate payments of $0.2 million in both 2008 and 2009.

There were no other material changes, other than from the normal course of business, to MGE Energy's and MGE's contractual obligations (representing cash obligations that are considered to be firm commitments) and commercial commitments (representing commitments triggered by future events) during the six months ended June 30, 2008. Further discussion of the contractual obligations and commercial commitments is included in Footnote 10 of this filing and Footnote 18 in MGE Energy's and MGE's annual reports on Form 10-K for the year ended December 31, 2007.

Cash Provided by Operating Activities

MGE Energy

MGE Energy's consolidated net cash provided by operating activities is derived mainly from the electric and gas operations of its principal subsidiary, MGE.

Cash provided by operating activities for the six months ended June 30, 2008, was $62.5 million, an increase of $10.7 million when compared to the same period in the prior year.

MGE Energy's net income increased $2.1 million for the six months ended June 30, 2008, when compared to the same period in the prior year.

Page 44

Depreciation for the six months ended June 30, 2008, was $19.3 million compared to $16.1 million in the same period in the prior year. This increase is primarily attributable to higher levels of assets, including the Top of Iowa III wind-powered electric generating facility which was placed in service in the first quarter of 2008 as well as accelerated depreciation of certain Blount assets. For additional information on the Blount accelerated depreciation, see Footnote 11.

Deferred taxes increased $3.4 million for the six months ended June 30, 2008 compared to the six months ended June 30, 2007, primarily due to bonus tax depreciation as a result of the Economic Stimulus Act of 2008.

Working capital accounts contributed to $15.2 million in cash provided by operating activities for the six months ended June 30, 2008, compared to $11.1 million during the same period in the prior year. Part of this change is related to the $2.4 million 2006 fuel refund returned to customers in April 2007.

During the six months ended June 30, 2008 and 2007, MGE Energy made $6.5 million and $4.9 million, respectively, in discretionary contributions to the pension and other postretirement plans. See Footnote 8 for further discussion of MGE Energy's Pension and Other Postretirement Benefits.

Capitalization Ratios

MGE Energy's capitalization ratios were as follows:

	MGE Energy
	June 30, 2008	Dec. 31, 2007
Common shareholders' equity	54.2%	53.9%
Long-term debt*	32.1%	33.1%
Short-term debt	13.7%	13.0%

*Includes the current portion of long-term debt.

MGE Energy's and MGE's Capital Requirements

As of June 30, 2008, MGE and MGE Energy had a working capital deficit (current liabilities exceeded current assets). This deficit is in part due to MGE funding the majority of its capital commitments for the Top of Iowa III wind project and the Elm Road project with short-term debt and the reclassification of $30.0 million of long-term debt which matures in September 2008, from a long-term to a current liability. MGE intends to refinance the $30 million medium-term note with an additional long-term debt facility. MGE intends to fund future capital commitments for the Elm Road projects with funds generated from normal operations, the issuance of long-term debt, and financing received from MGE Energy. MGE Energy intends to raise the funds for such financing primarily through the issuance of equity securities and short-term debt, as needed.

MGE Energy's and MGE's liquidity are primarily affected by their capital requirements. During the six months ended June 30, 2008, capital expenditures for MGE Energy and MGE totaled $61.1 million, which included $30.5 million of capital expenditures for Elm Road, $0.2 million of capital expenditures for MGE Power West Campus, $7.7 million for the Top of Iowa III wind project, and $22.7 million of capital expenditures for other utility operations.

The following table shows MGE's current credit ratings. The ratings presented reflect the current views of these rating agencies and are subject to change. MGE Energy is not yet rated because it has not issued any debt securities.

	Standard & Poor's	Moody's
First Mortgage Bonds	AA-	Aa2
Unsecured Medium Term Notes	AA-	Aa3
Commercial Paper	A1+	P1

MGE's access to the capital markets, including the commercial paper market and its financing costs in those markets, is dependent on its securities' ratings. None of MGE's borrowings is subject to default or prepayment due to downgrading of securities' ratings, although MGE's future interest expense may be affected by a change in those ratings.

Environmental Matters

The following discussion is limited to updates or developments in environmental matters that occurred during the six months ended June 30, 2008. Further discussion of environmental matters is included in MGE Energy's and MGE's annual reports on Form 10-K for the year ended December 31, 2007.

State mercury rules

In June 2008, the Wisconsin Natural Resources Board approved the final NR 446 rule which is now subject to legislative review under Wisconsin's process. The state's rule is significantly different from the federal CAMR that was vacated in February 2008 by the U.S. Court of Appeals for the District of Columbia Circuit. See Item 1. Business in MGE Energy's and MGE's annual reports on Form 10-K for the year ended December 31, 2007, for additional discussion of the federal CAMR. NR 446 will require large coal-fired Electric Generating Units (EGUs larger than 150 MW) to reduce mercury emissions by 90% beginning in 2015, or choose a multi-pollutant reduction approach, which allows a stepped approach to mercury reduction while reducing NO_x and SO₂emissions at prescribed rates. Smaller coal-fired EGUs, those between 25 – 150 MW in size, will need to apply Best Available Control Technology (BACT) to achieve mercury reductions. This rule will require additional pollution controls at Columbia, and may cost Blount and Elm Road additional capital and operating costs. Exact costs are unknown at this time.

Federal National Ambient Air Quality Standards

Federal Clean Air Interstate Rule (CAIR)

On July 11, 2008, the DC Circuit Court of Appeals vacated and remanded the EPA's Clean Air Interstate Rule (CAIR). See Part I. Item 1. Business, Environmental, Air Quality in the December 31, 2007 10-K for additional information on CAIR. It is unclear at this time how the EPA will respond to the Court of Appeals decision. The State of Wisconsin's NR 432 deals with NO_Xallocations under CAIR, and portions of Wisconsin's Best Available Retrofit Technology (BART) rule defer to CAIR when dealing with emissions from EGUs subject to CAIR. It is unclear what steps the State will be taking to resolve these rules in light of the CAIR vacatur.

Global Climate Change

On March 27, 2008, the U.S. EPA sent letters to various environmental committees in the U.S. Senate and House of Representatives announcing their plans to address their obligations under the Supreme Court's ruling in Massachusetts v. EPA. The letters to Congress indicated that the EPA sees any Green House Gas regulations that they develop to be far-reaching and likely to include both mobile and stationary sources. In July 2008, the EPA issued an Advance Notice of Proposed Rulemaking seeking comment on a large array of possible regulatory actions it is contemplating under the federal Clean Air Act to reduce greenhouse gas emissions. The proposed rules impact virtually all aspects of the economy including electric and natural gas utilities. The EPA document follows last year's U.S. Supreme Court decision requiring the EPA to regulate greenhouse gas emissions under the Clean Air Act if it finds that they endanger public health or welfare. The document seeks comment on whether the EPA should make that finding and, if so, the types of regulations it should adopt. There will be a 120 day comment period commencing when the document is published in the Federal Register. It is unknown at this time what impact, if any, such a finding would have on us.

A final report from Governor Doyle's Global Warming Task Force was approved on July 24, 2008, concluding over a year's work by the task force.

We cannot predict the timing or results, or the effect upon construction schedule or costs, of any decision by any administrative or legal process that may follow.

Columbia

MGE and two other utilities jointly own Columbia, a coal-fired generating facility, which accounts for 225 MW (29%) of MGE's net generating capability. Various environmental initiatives are expected to result in significant additional operating and capital expenditures at Columbia. The operator's current estimates show that MGE's share of the capital expenditures required to comply with various environmental initiatives will be between $130 million and $200 million. According to current estimates, compliance with various environmental initiatives is also expected to result in an increase to MGE's pro-rata share of Columbia's ongoing operating expenses. The operator and MGE management are continuing to explore various alternatives to comply with these standards. Accordingly, actual capital expenditures may fall above or below the range provided. MGE expects that the costs to comply with these standards will be fully recoverable through rates.

Restructuring Activities

MGE will recover in rates the costs associated with the discontinuance of coal at Blount. As such, the severance charges for these employees have been deferred and recognized on the consolidated balance sheet of MGE Energy and MGE as a regulatory asset.

Other Regulatory Matters

Fuel filing

On May 30, 2008, MGE filed with the PSCW a limited scope reopener of its 2009 electric rates with the PSCW. The application included an update to MGE's electric fuel costs monitored under the fuel rules and an update to the Elm Road costs. If approved by the PSCW, the net effect of the requested changes would result in a 6.99% increase, on average, in retail electric rates.

Page 49

Fuel surcharge

On May 5, 2008, the PSCW approved a $0.00239 per kWh interim fuel surcharge on MGE's electric rates. This interim fuel surcharge will result in an estimated $8.0 million increase in electric revenues on an annual basis. The interim fuel surcharge was included in electric rates as of May 6, 2008. Pursuant to the provisions of this interim order, MGE's electric revenues resulting from this interim surcharge are subject to refund with interest at 10.8% should it ultimately be determined that the interim fuel surcharge resulted in collections greater than actual costs.

New Accounting Principles

Pension Protection Act

During the third quarter of 2006, President Bush signed into law the Pension Protection Act of 2006, which will affect the manner in which companies, including MGE and MGE Energy, administer their pension plans. This legislation will require companies to, amongst other things, increase the amount by which they fund their pension plans, pay higher premiums to the Pension Benefit Guaranty Corporation if they sponsor defined benefit plans, amend plan documents and provide additional plan disclosures in regulatory filings and to plan participants. This legislation became effective as of January 1, 2008. The U.S. Treasury Department's interim guidance indicates that further guidance is forthcoming. MGE does not expect significant changes in expected cash flows as a result of the Act. Absent changes in plan design as a result of the Act, the Act is not expected to materially impact MGE and MGE Energy's results of operations.

FSP FIN 39-1

In April 2007, the FASB issued FSP 39-1, Amendment of FASB Interpretation No. 39 (FSP FIN 39-1). This pronouncement amends FIN 39, Offsetting of Amounts Related to Certain Contracts, and allows companies to offset fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) against fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting agreement. MGE and MGE Energy elected the net presentation as prescribed by this pronouncement. FSP FIN 39-1 became effective for MGE and MGE Energy as of January 1, 2008. The effects of applying this pronouncement shall be recognized as a change in accounting principle through retroactive application for all financial statements presented. The adoption of this pronouncement did not have any impact on MGE or MGE Energy's net income. At June 30, 2008, MGE Energy and MGE did not have any cash collateral to net against the net derivative positions with counterparties.

FAS 160 and FAS 141(R)

In December 2007, the FASB issued FAS 160, Non-Controlling Interests in Consolidated Financial Statements, an amendment of ARB No. 51 and FAS 141(R), Business Combinations. These pronouncements will change the accounting and reporting for business acquisitions and noncontrolling interest in a subsidiary. In addition, FAS 160 will change the accounting and reporting for the deconsolidation of a subsidiary. FAS 160 and FAS 141(R) will be effective for MGE and MGE Energy as of January 1, 2009. MGE and MGE Energy are currently assessing the impact these pronouncements will have on their financial statements.

FAS 161

Page 50

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

MGE Energy and MGE are potentially exposed to market risk associated with interest rates, commodity prices, weather, and equity returns. MGE currently has no exposure to foreign currency risk. MGE manages some risk exposure through risk management policies and uses derivative instruments. MGE's market risk has not changed between 2007 and 2008. MGE does not enter into speculative trading transactions.

Weather Risk

MGE's sales forecasts, used to establish rates, are set by the PSCW based upon estimated temperatures, which approximate 20-year averages. MGE's electric revenues are sensitive to the summer cooling season and, to some extent, to the winter heating season. A significant portion of MGE's gas system demand is driven by heating. MGE's gas revenues are collected under a combination of fixed and volumetric rates set by the PSCW based on "normal weather." As a result of weather-sensitive demand and volumetric rates, a portion of MGE's gas revenue is at risk for warmer-than-normal weather. MGE may use weather derivatives, pursuant to its risk management program, to reduce the impact of weather volatility on its gas revenues.

MGE may also be impacted by extreme weather conditions such as hurricanes or tornados. Such conditions may damage critical operating assets or may negatively impact the price of commodity and other costs.

A summary of actual weather information in the utility segment's service territory during the three and six months ended June 30, 2008, as measured by degree days, may be found in results of operations.

Commodity Price Risk

MGE has commodity price risk exposure with respect to the price of natural gas, electricity, coal, emission credits, and oil. MGE employs established policies and procedures to reduce the market risks associated with changing commodity prices. MGE's commodity risks are somewhat mitigated by the current ratemaking process in place for recovering electric fuel cost, purchased energy costs, and the cost of natural gas. MGE's electric fuel costs are subject to fuel rules established by the PSCW.

MGE's electric operations burn natural gas in several of its peak power plants or as a supplemental fuel at several coal-fired plants and, in many cases, the cost of purchased power is tied to the cost of natural gas. MGE bears significant regulatory risk for the recovery of such fuel and purchased power costs when they are higher than the base rate established in its current rate structure.

Under the electric fuel rules, MGE may be required to refund to customers if its actual fuel costs fall outside the lower end of the range and would be allowed to request a surcharge if those actual fuel costs exceed the upper end of the range. The range is defined by the PSCW and has been modified throughout the years based on market conditions and other relevant factors. Pursuant to the PSCW order issued on December 14, 2007, MGE's electric fuel rules monitored range is a plus or minus 2% range. MGE assumes the risks and benefits of variances that are within the 2% bandwidth. For 2008 as updated for the interim fuel surcharge, fuel and purchased power costs included in MGE's base fuel rates are $126.8 million. See Footnote 14.b. for additional information. MGE's gas segment is governed by the purchased gas adjustment clause (PGA). Under the PGA, MGE is able to pass through to customers the cost of gas, subject to certain limited incentives. Under both the electric fuel rules and PGA clause, MGE may include in the cost of fuel (natural gas or power) the costs and benefits of fuel price risk management tools implemented under the risk management plan approved by the PSCW.

MGE also reduces price risk caused by market fluctuations via physical contracts and financial contracts, including futures, swaps, options, and forwards. The financial contracts currently being cash-flow hedged are no greater than one year, except for the ten-year purchased power agreement described below.

At June 30, 2008, MGE has financial gas and electric commodity contracts to hedge commodity price risk in the gas and electric segments. These contracts are primarily comprised of exchange-traded option and future contracts to manage the cost of gas. MGE also holds FTRs which are used to hedge the risk of increased electric transmission congestion charges. At June 30, 2008, the net market value of all these aforementioned instruments exceeded their costs by $5.4 million.

Page 51

Interest Rate Risk

Both MGE and MGE Energy have short-term borrowings at varying interest rates. MGE issues commercial paper for its short-term borrowings, while MGE Energy draws from its current credit facility to meet its short-term borrowing needs. Borrowing levels vary from period to period depending upon capital investments and other factors. Future short-term interest expense and payments will reflect both future short-term interest rates and borrowing levels. MGE Energy and MGE manage interest rate risk by limiting their variable rate exposure and continually monitoring the effects of market changes on interest rates. MGE is not exposed to changes in interest rates on a substantial portion of its long-term debt until that debt matures and is refinanced at market rates.

Equity Price Risk - Pension-Related Assets

MGE currently funds its liabilities related to employee benefits through trust funds. These funds, which include investments in debt and equity securities, are managed by various investment managers. Changes in market value of these investments can have an impact on the future pension and postretirement expenses.

Credit Risk - Counterparty

Credit risk is the loss that may result from counterparty nonperformance. MGE is exposed to credit risk primarily through its merchant energy business. MGE uses credit policies to manage its credit risk, which includes utilizing an established credit approval process, monitoring counterparty limits, employing credit mitigation measures such as collateral or prepayment arrangements, and using netting agreements.

Due to the possibility of extreme volatility in the prices of energy commodities and derivatives, the market value of contractual positions with individual counterparties could exceed established credit limits or collateral provided by those counterparties. If such a counterparty were then to fail to perform its obligations under its contract (for example, fail to deliver the electricity MGE originally contracted for), MGE could sustain a loss that could have a material impact on its financial results.

Additionally, if a counterparty were to default and MGE were to liquidate all contracts with that entity, MGE's credit loss would include the loss in value of mark-to-market contracts; the amount owed for settled transactions; and additional payments, if any, to settle unrealized losses on accrual contracts.

MGE is obligated to provide service to all electric and gas customers within its respective franchised territories. MGE's franchised electric territory includes a 315 square-mile area in Dane County, Wisconsin, and MGE's franchised gas territory includes a service area covering 1,625 square miles in Wisconsin. Based on results for the year ended December 31, 2007, no one customer constituted more than 7% of total operating revenues for MGE and MGE Energy. Credit risk for electric and gas is managed by MGE's credit and collection policies, which are consistent with state regulatory requirements.

Cash, cash equivalents, and customer accounts receivable are the financial instruments that potentially subject MGE Energy and MGE to concentrations of credit risk. MGE Energy and MGE place their cash and cash equivalents with high credit-quality financial institutions. MGE has limited concentrations of credit risk from customer accounts receivable because of the large number of customers and strong economy in its service territory.

Page 52

Item 4. Controls and Procedures.

During the second quarter of 2008, MGE Energy's management, including the principal executive officer and principal financial officer, evaluated its disclosure controls and procedures related to the recording, processing, summarization, and reporting of information in its periodic reports that it files with the SEC. These disclosure controls and procedures have been designed to ensure that material information relating to MGE Energy, including its subsidiaries, is accumulated and made known to MGE Energy's management, including these officers, by other employees of MGE Energy and its subsidiaries as appropriate to allow timely decisions regarding required disclosure, and that this information is recorded, processed, summarized, evaluated, and reported, as applicable, within the time periods specified in the SEC's rules and forms. Due to the inherent limitations of control systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in decision making can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. Also, MGE Energy does not control or manage certain of its unconsolidated entities and thus, its access and ability to apply its procedures to those entities is more limited than is the case for its consolidated subsidiaries.

As of June 30, 2008, the principal executive officer and the principal financial officer concluded that MGE Energy's disclosure controls and procedures were effective to accomplish their objectives. MGE Energy intends to continually strive to improve its disclosure controls and procedures to enhance the quality of its financial reporting.

During the quarter ended June 30, 2008, there were no changes in MGE Energy's internal controls over financial reporting that materially affected, or are reasonably likely to materially affect, MGE Energy's internal control over financial reporting.

Item 4T. Controls and Procedures.

During the second quarter of 2008, MGE's management, including the principal executive officer and principal financial officer, evaluated its disclosure controls and procedures related to the recording, processing, summarization, and reporting of information in its periodic reports that it files with the SEC. These disclosure controls and procedures have been designed to ensure that material information relating to MGE, including its subsidiaries, is accumulated and made known to MGE's management, including these officers, by other employees of MGE and its subsidiaries as appropriate to allow timely decisions regarding required disclosure, and that this information is recorded, processed, summarized, evaluated, and reported, as applicable, within the time periods specified in the SEC's rules and forms. Due to the inherent limitations of control systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in decision making can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. Also, MGE does not control or manage certain of its unconsolidated entities and thus, its access and ability to apply its procedures to those entities is more limited than is the case for its consolidated subsidiaries.

As of June 30, 2008, the principal executive officer and the principal financial officer concluded that MGE's disclosure controls and procedures were effective to accomplish their objectives. MGE intends to continually strive to improve its disclosure controls and procedures to enhance the quality of its financial reporting.
