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.

Management's Discussion and Analysis of Financial Condition and Results of Operations in this report, and Item 8. Financial Statements and Supplementary Data – Note 18, as updated by Part I, Item 1. Financial Statements – Note 8 in this report, and (b) other factors discussed herein and in other filings made by that registrant with the SEC.

MGE Energy, Inc., and Madison Gas and Electric Company

Notes to Consolidated Financial Statements (unaudited)

March 31, 2013

Basis of Presentation - MGE Energy and MGE.

This report is a combined report of MGE Energy and MGE. References in this report to "MGE Energy" are to MGE Energy, Inc., and its subsidiaries. References in this report to "MGE" are to Madison Gas and Electric Company.

MGE Power Elm Road and MGE Power West Campus own electric generating assets and lease those assets to MGE. Both entities are variable interest entities under applicable authoritative guidance. MGE is considered the primary beneficiary of these entities as a result of contractual agreements. As a result, MGE has consolidated MGE Power Elm Road and MGE Power West Campus. See Footnote 2 of Notes to Consolidated Financial Statements under Item 8, Financial Statements and Supplementary Data, of MGE Energy's and MGE's 2012 Annual Report on Form 10-K.

The accompanying consolidated financial statements as of March 31, 2013, and for the three months ended, are unaudited, but include all adjustments that MGE Energy and MGE management consider necessary for a fair statement of their respective financial statements. All adjustments are of a normal, recurring nature except as otherwise disclosed. The year-end consolidated balance sheet information was derived from the audited balance sheet appearing in MGE Energy's and MGE's 2012 Annual Report on Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America. These notes should be read in conjunction with the financial statements and the notes on pages 51 through 104 of the 2012 Annual Report on Form 10-K.

Equity and Financing Arrangements - MGE Energy.

Common Stock.

MGE Energy purchases stock in the open market for issuance pursuant to its Stock Plan. All MGE Energy common stock issued under the Stock Plan is sold pursuant to a registration statement that has been filed with the SEC and is currently effective.

MGE Energy can issue new shares of its common stock through the Stock Plan. For both the three months ended March 31, 2013 and 2012, MGE Energy did not issue any new shares of common stock under the Stock Plan.

Dilutive Shares Calculation.

MGE Energy does not hold any dilutive securities.

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 Energy and MGE.

MGE Transco has accounted for its investment in ATC under the equity method of accounting. For the three months ended March 31, 2013 and 2012, MGE Transco recorded equity earnings from the investment in ATC of $2.4 million and $2.2 million, respectively. Dividend income received from ATC was $1.8 million and $1.7 million for the three months ended March 31, 2013 and 2012, respectively. In addition, during the three months ended March 31, 2013 and 2012, MGE Transco made $0.2 million and $0.4 million in capital contributions to ATC, respectively. On April 30, 2013, MGE Transco made a $0.5 million capital contribution to ATC.

MGE Energy and MGE's investment in ATC as of March 31, 2013, and December 31, 2012, was $61.8 million and $61.0 million, respectively.

At March 31, 2013, 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 noncontrolling interest.

ATC's summarized financial data for the three months ended March 31, 2013 and 2012, is as follows:


		Three Months Ended March 31,

Columbia Environmental Project Construction - MGE Energy and MGE.

MGE and two other utilities jointly own Columbia, a coal-fired generating facility. WPL is the plant operator and permit holder, and owns 46.2% of Columbia. WPSC owns a 31.8% interest, and MGE owns a 22% interest, in Columbia. In early 2011, the PSCW issued a Certificate and Order authorizing the construction of scrubbers and bag houses and associated equipment on Columbia Units 1 and 2 to reduce SO₂ and mercury emissions. The scrubbers and bag houses are expected to support compliance obligations for current and anticipated air quality regulations, including CAIR, CAIR's eventual replacement, the Mercury and Air Toxics Standards (MATS), and the Wisconsin Mercury Rule. The operator's current estimate shows that MGE's share of the capital expenditures required for this project is approximately $140 million. As of March 31, 2013, MGE had accumulated $78.8 million (excluding carrying costs) related to its share of the project, which is reflected in the Construction Work in Progress balance on MGE Energy's and MGE's consolidated balance sheets. MGE's share of the capital expenditures associated with the Columbia environmental project will be approximately $49 million for the remainder of 2013 and $12 million in 2014. These amounts may change as a result of modifications to the project estimate or timing differences. For the three months ended March 31, 2013 and 2012, MGE has recognized after tax $0.5 million and $0.1 million, respectively, in AFUDC equity related to this project.

MGE expects that the costs pertaining to this project will be fully recoverable through rates. In 2012, the PSCW authorized MGE 100% AFUDC on this project during construction. Beginning in 2013, similar to MGE's other utility construction projects, the PSCW authorized MGE a 50% current return (included in customer rates) and the remaining 50% as AFUDC.

Taxes - MGE Energy and MGE.

Accounting for Uncertainty in Income Taxes.

MGE Energy and MGE account for the difference between the tax benefit amount taken on prior year tax returns, or expected to be taken on a current year tax return, and the tax benefit amount recognized in the financial statements as an unrecognized tax benefit.

MGE Energy has adopted a tax method of accounting to accelerate tax deductions for repairs. MGE Energy and MGE have an unrecognized tax benefit at March 31, 2013, and December 31, 2012, in the amount of $3.4 million and $3.2 million, respectively, for the tax uncertainty related to the change in tax method of accounting for repairs.

On April 18, 2013, MGE Energy received notification from the Internal Revenue Service that the examination of tax periods 2007-2009 has been completed. Unrecognized tax benefits of $1.5 million related to those years will be reversed (in the second quarter) due to those positions not being adversely adjusted in the examination.

Effective Tax Rate.

MGE Energy's and MGE's effective income tax rate for the three months ended March 31, 2013, was 37.7%, compared to 38.1% for the same period in 2012.

Pension and Other Postretirement Plans - MGE Energy and MGE.

MGE maintains qualified and nonqualified pension plans, health care, and life insurance benefits. Additionally, MGE has defined contribution 401(k) benefit plans.

The following table presents the components of MGE Energy's and MGE's net periodic benefit costs recognized for the three months ended March 31, 2013 and 2012. A portion of the net periodic benefit cost is capitalized within the consolidated balance sheets.

The PSCW allowed MGE to defer the 2009 incremental pension and OPRB costs above the amounts recovered in rates. During both the three months ended March 31, 2013 and 2012, $0.3 million has been recovered in rates. These costs are not reflected in the table above.

Share-Based Compensation - MGE Energy and MGE.

Under MGE Energy's Performance Unit 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.

In addition to units granted in 2009 through 2012, on February 15, 2013, 15,256 units were granted based on the MGE Energy closing stock price as of that date. These units are subject to a five-year graded vesting schedule. On the grant date, MGE Energy and MGE measure the cost of the employee services received in exchange for a performance unit award based on the current market value of MGE Energy common stock. The fair value of the awards has been subsequently re-measured at March 31, 2013, as required by applicable accounting standards. Changes in fair value have been recognized as compensation cost. Since this amount is re-measured quarterly 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. Compensation cost for retirement eligible employees or employees that will become retirement eligible during the vesting schedule are recognized on an abridged horizon. In the event of a bona fide retirement, not followed by work for a competitor, the executive will receive full vesting credit for each outstanding award.

During the three months ended March 31, 2013 and 2012, MGE recorded $0.9 million and $0.4 million, respectively, in compensation expense as a result of the Performance Unit Plan. In January 2013, cash payments of $1.0 million were distributed relating to awards that were granted in 2008 and became payable under the Performance Unit Plan. No forfeitures occurred during the three months ended March 31, 2013 or 2012. At March 31, 2013, $3.7 million of outstanding awards are vested.

Commitments and Contingencies.

Environmental - MGE Energy and MGE.

Water Quality

Water quality regulations promulgated by the EPA and WDNR in accordance with the Federal Water Pollution Control Act, or more commonly known as the Clean Water Act (CWA), impose restrictions on discharges of various pollutants into surface waters. The CWA also regulates surface water quality issues that affect aquatic life, such as water temperatures, intake structures, and wetlands filling. The CWA also includes discharge standards, which require the use of effluent-treatment processes equivalent to categorical "best practicable" or "best available" technologies. The CWA regulates discharges from "point sources" such as power plants through establishing discharge limits in water discharge permits. MGE's power plants operate under Wisconsin Pollution Discharge Elimination System (WPDES) permits to ensure compliance with these discharge limits.

EPA Cooling Water Intake Rules (Section 316(b))

Section 316(b) of the Clean Water Act requires that the cooling water intake structures at electric power plants meet best available technology standards so that mortality from entrainment (drawing aquatic life into a plant's cooling system) and impingement (trapping aquatic life on screens) are reduced. Section 316(b) has been introduced in two phases. Phase I, which has been finalized, covered new facilities at the time that the rule was introduced. Phase II, which has not been finalized, is designed to cover what is defined as existing facilities. The EPA issued a proposed Phase II rule and alternative compliance strategies for existing facilities in April 2011 and has until June 27, 2013, to issue a final rule, pursuant to a settlement agreement.

The currently proposed Phase II rule and potential alternatives allow for a state permitting agency's discretion in determining best technology available at plants that are under their permitting authority and is not requiring cooling towers in all instances. The WDNR holds permitting authority for Wisconsin and implementation of the rule will be through modification of the plants' WPDES permits. Blount and Columbia generating plants are subject to both the impingement and entrainment aspects of the current proposed rule. WCCF is subject to the impingement aspect only. The Elm Road Units are covered under Phase I of the rule and meets those requirements. We anticipate that under the current proposed rule, equipment would need to be installed at Blount, WCCF, and Columbia to meet these new standards. However it is not presently possible to estimate the potential costs associated with this rule because the rule has not been finalized.

Air Quality

Federal and state air quality regulations impose restrictions on emission of particulate matter (PM), 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. Various initiatives, including interstate pollution transport rules, maximum achievable control technology (MACT) standards, new source performance standards (NSPS), the Clean Air Visibility Rule (also known as the Regional Haze Rule), and mercury emissions limits are expected to result in additional operating and capital expenditure costs for electric generating units.

Vacation of EPA's Cross State Air Pollution Rule (CSAPR) and Reinstatement of the Clean Air Interstate Rule (CAIR)

In 2005, EPA promulgated the Clean Air Interstate Rule (CAIR) to reduce ozone and fine particulate matter emissions by reducing NO_x and SO₂ emissions. NO_x and SO₂ interact in the atmosphere to form ambient ozone from NO_x and fine particulate matter pollution from NO_x and SO₂. The CAIR generally requires NO_x and SO₂ emission reductions from fossil fuel-fired EGUs (25 MW or greater) in the eastern half of the United States in two phases and includes a regional cap-and-trade system. The first phase (currently in place)

requires annual regional emission reductions from 2003 levels of 55% for NO_x and 40% for SO₂. The second phase (beginning in 2015) reduces regional NO_x and SO₂ emissions further from 2003 levels to 65% and 70%, respectively. MGE owns or has partial ownership in several generation units currently subject to the CAIR: Blount, Columbia, Elm Road Units, and its combustion turbines located in West Marinette and Fitchburg.

In December 2008, the U.S. Court of Appeals for the D.C. Circuit remanded the CAIR to the EPA with directions to revise or replace the rule. The Court's remand order directed that the CAIR remain in effect until the EPA promulgated a replacement rule. The Court's order did not include a deadline for the EPA to act.

In August 2011, the EPA responded to the remand of the CAIR by promulgating the Cross State Air Pollution Rule (CSAPR). However, in August 2012, the U.S. Court of Appeals for the D.C. Circuit vacated CSAPR and instructed the EPA to continue administering the CAIR pending finalizing a valid alternative program to control interstate pollution. In January 2013, the U.S. Court of Appeals for the D.C. Circuit denied the EPA's petition for reconsideration en banc. The EPA and several environmental groups have appealed the D.C. Circuit Court's August 2012 decision to the Supreme Court in separate filings. At this time, the CAIR remains effective.

MGE is currently in compliance with the CAIR Phase I requirements. MGE will be able to meet Phase II NO_x emissions reductions through using our NO_x allowances provided through the rule, and we will meet Phase II SO₂ emissions reductions through installation of pollution controls. New SO₂ controls at Columbia are already underway and are planned to be completed by mid 2014 (see the discussion regarding the Columbia environmental project below). MGE expects that any costs incurred to meet Phase II of the CAIR will be fully recoverable through rates. MGE will monitor the Supreme Court's response to the CSAPR appeals and any subsequent actions by the EPA to continue to evaluate potential impacts to our operations.

Clean Air Visibility Rule (CAVR)

Air modeling indicates that SO₂ and NO_x emissions (and to a lesser extent particulate matter) from Columbia may impair visibility at certain Class I Scenic Areas and may therefore be subject to the best available retrofit technology (BART) regulations, a subsection of the EPA's Clean Air Visibility Rule (CAVR), which may require pollution retrofits. The EPA had proposed that a power plant's compliance with emissions limitations in the CAIR and later under CSAPR could also serve as compliance with the BART regulations for SO₂ and NO_x emissions. However, this proposal is now uncertain because of the D.C. Circuit decisions to remand the CAIR and vacate CSAPR and the EPA's decision to pursue Supreme Court review of the CSAPR vacature. See CAIR and CSAPR discussion above for additional information on these proceedings. Capital expenditures at Columbia under BART still remain a possibility however at this time, the BART regulatory obligations, compliance strategies and costs remain uncertain until the Supreme Court makes a decision regarding CSAPR.

Wisconsin State Mercury Rule

Beginning January 1, 2015, phase two of the Wisconsin mercury rule will require large coal-fired EGUs (larger than 150 MW) to reduce mercury emissions by 90%, or choose a multi-pollutant reduction approach, which allows a stepped approach to mercury reduction while reducing NO_x and SO₂emissions at prescribed rates. The Elm Road Units currently meet this requirement. The Columbia co-owners expect to meet the 90% reduction option by installing baghouses and scrubbers by mid 2014 (see the discussion regarding the Columbia environmental project below). With the finalization of the EPA's Mercury and Air Toxics Standard, or MATs, the WDNR is currently evaluating how the state mercury rule should be supplanted by the EPA's rule (see discussion on MATs below).

Mercury and Air Toxics Standards (MATs) for Utility Boilers (Also Referred to as the Maximum Achievable Control Technology, or MACT)

In December 2011, the EPA finalized its Mercury and Air Toxics Standards for coal and oil-burning EGU boilers. MATs will require emissions standards for mercury, non-mercury HAPs metals, and acid gases. Compliance with MATs is generally required three years from the rule issuance, but permitting authorities can grant an additional year for compliance to facilities. MGE's Columbia and Elm Road Units are subject to MATs. The Elm Road Unit's current pollution controls, and Columbia's planned mercury pollution controls (baghouse and scrubbers) to be installed by mid 2014, are expected to allow both facilities to comply with the MATs rule without extensions (see the discussion regarding Columbia environmental project below).

National Ambient Air Quality Standards

The EPA has developed National Ambient Air Quality Standards (NAAQS) for six compounds currently identified as criteria pollutants: nitrogen dioxide, particulate matter, ozone, sulfur dioxide, lead, and carbon monoxide. The NAAQS for criteria pollutants establish acceptable ambient air levels of each pollutant based on a review of their effects to human health and the environment, and changes to those NAAQS can affect compliance requirements and associated capital and operating costs. The EPA is required to review NAAQS every five years.

Certain stationary sources, such as MGE's generation facilities, must meet NAAQS standards for emissions that travel offsite. Stationary source air quality modeling is used to determine whether emissions from permitted sources meet these NAAQS. Failure to meet NAAQS may require a permit applicant to incur capital or operational costs to bring a source into compliance. We cannot predict if MGE's permitted stationary sources will have difficulty meeting new standards not previously modeled. Modeling performed by the WDNR for MGE's permitted facilities has demonstrated compliance with current NAAQS. Additional modeling may be required in future permitting actions.

MGE tracks NAAQS developments to determine if new standards may affect us. MGE is currently tracking two NAAQS developments: (1) determination and placement of monitoring networks in Wisconsin for the 2010 nitrogen dioxide (NO₂) NAAQS (Wisconsin is currently considered in attainment with NO₂ NAAQS, however stationary source modeling may be required for NO₂in the future) and (2) implementation requirements under the 2010 sulfur dioxide (SO₂) NAAQS. The EPA has issued draft guidance that indicates larger sources, such as Columbia, may be required to install ambient air monitors and/or perform dispersion modeling to demonstrate attainment. A concern has been raised regarding the current EPA-preferred dispersion model. The model may not be accurate for estimating SO₂ stationary source impacts and may overestimate off-site concentrations of SO₂ from stationary sources. The EPA is working to resolve issues with the model.

Reciprocating Internal Combustion Engine (RICE) MACT Standard

In January 2013, the EPA finalized amendments to its RICE MACT standard. RICE MACT applies to industrial or electrical engines that are classified as reciprocating internal combustion engines. Engines owned by MGE that would fall under the RICE MACT rule include backup generators and small engines at various locations, including our fleet of distributed generators that serve as electric system backup and emergency dispatch. The distributed generators in particular will either require additional pollution controls or a change in how they are dispatched. MGE is continuing to evaluate the impacts to our engines based on this new standard, including evaluating the costs associated with adding pollution controls on some or all our aforementioned distributed generators.

Greenhouse Gas Regulation

On March 27, 2012, the EPA proposed GHG New Source Performance Standards (NSPS) for coal fired and natural gas combined cycle (NGCC) EGUs. The proposal applies to new EGUs only.

However, the EPA plans to propose NSPS for existing units some time in 2013 as part of a 2010 settlement agreement. There is a great deal of uncertainty as to what the EPA will include in their NSPS for existing units and thus we are unable to comment on potential impacts to MGE at this time.

Columbia

MGE and two other utilities jointly own Columbia, a coal-fired generating facility, which accounts for 225 MW (29%) of MGE's net summer generating capability. WPL is the plant operator and permit holder, and owns 46.2% of Columbia. Wisconsin Public Service Corporation (WPSC) owns a 31.8% interest, and MGE owns a 22% interest in Columbia. Based upon current available information, compliance with various environmental requirements and initiatives is expected to result in significant additional operating and capital expenditures at Columbia.

Columbia Environmental Project

In early 2011, the PSCW issued a Certificate and Order authorizing the construction of scrubbers and bag houses and associated equipment on Columbia Units 1 and 2 to reduce SO₂ and mercury emissions. The scrubbers and bag houses are expected to support compliance obligations for current and anticipated air quality regulations, including CAIR, CAIR's eventual replacement, the Mercury and Air Toxics Standards

(MATs), and the Wisconsin Mercury Rule. WPL, the plant operator, currently estimates that MGE's share of the capital expenditures required for this project is approximately $140 million. The project is underway and estimated to be completed by mid 2014.

MGE's share of various contractual commitments entered for the project as of March 31, 2013, is $56.7 million. These costs are expected to be capitalized and included in the consolidated balance sheets of MGE Energy and MGE. See Footnote 4 for further information regarding the Columbia environmental construction project.

Title V Operating Permit Petition

In September 2008, the WDNR issued a Title V renewal operating permit to WPL for Columbia. However, a citizen group petitioned the EPA to object to the permit renewal. In October 2009, the EPA issued an order granting in part and denying in part the petition and sent the operating permit back to the WDNR for further review based on the EPA order. In February 2011, the citizen group involved filed an action against the EPA in the U.S. District Court for the Western District of Wisconsin seeking to have the EPA take over the permit process. In June 2012, the EPA notified the plant operator of its intent to assume responsibility for issuing the renewed operating permit for Columbia, but agreed to provide the plant operator with more time to potentially resolve the issues raised in the EPA's order. On February 4, 2013, the parties involved dismissed the litigation without prejudice. The matter is still pending at the EPA but has been postponed pending possible resolution of the Clean Air Act litigation discussed below. MGE believes the permits currently in effect for Columbia remain in place at this time. MGE continues to follow these developments and is unable to predict the outcome of this matter and its impact on its operations or financial condition.

Columbia Clean Air Act Litigation

In December 2009, the EPA sent a notice of violation (NOV) to MGE as one of the co-owners of Columbia. The NOV alleges that WPL, as operator, and the co-owners (WPL, WPS, and MGE) failed to comply with appropriate pre-construction review and permitting requirements and, as a result, violated the PSD program requirements, the Title V operating permit requirements of the CAA and the Wisconsin State Implementation Plan (SIP). In September 2010, Sierra Club filed a lawsuit against WPL alleging violations of the CAA at Columbia and other WPL-operated Wisconsin facilities. WPL responded that the projects at Columbia were routine, or not projected to increase emissions, and therefore did not violate the permitting requirements of the CAA.

In April 2013, WPL, as operator, along with the other owners of Columbia (MGE and WPS), entered into a consent decree with the EPA and the Sierra Club to resolve these claims, while admitting no liability. The consent decree has been lodged with, and is subject to approval by, the Court, which could occur in the second quarter of 2013. The consent decree, requires installation of the following emission controls at Columbia; scrubbers and baghouses at Columbia Units 1 and 2 by December 31, 2014 and an SCR system at Columbia Unit 2 by December 31, 2018. In addition, the consent decree establishes emission rate limits for SO₂, nitrogen oxide (NO_x) and particulate matter for Columbia Units 1 and 2. The consent decree also includes annual plant-wide emission caps for SO₂ and NO_x for Columbia. MGE will also pay approximately $0.2 million as its share of a civil penalty and complete approximately $0.6 million in environmental mitigation projects. MGE currently expects to recover any material costs that could be incurred by MGE related to the terms of the final consent decree from MGE's electric customers, except for costs related to the civil penalty. In accordance with applicable accounting standards, MGE has accrued an amount for this matter representing its best estimate of its probable liability, based upon its assessment of the settlement. That accrued amount is not material to the financial statements. MGE believes the likelihood of a materially greater liability than the accrued amount is remote based upon the current status.

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

MGE makes available to qualifying customers a financing program for the purchase and installation of 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 July 31, 2013. At March 31, 2013, MGE has outstanding a $4.3 million interest in these receivables. MGE retains the servicing responsibility for these receivables. As of March 31, 2013, the servicing asset recognized by MGE is $0.2 million.

MGE accounts 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 March 31, 2013, 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 underlying customer loan. Principal payments for the remainder of 2013 and the next four years on the loans are:

Legal Matters - MGE Energy and MGE.

MGE is involved in various legal matters that are being defended and handled in the normal course of business, including the Columbia matters discussed above. MGE maintains accruals for such costs that are probable of being incurred and subject to reasonable estimation. The accrued amount for these matters is not material to the financial statements.

Purchase Contracts - MGE Energy and MGE.

MGE Energy and MGE have entered into various commodity supply, transportation and storage contracts to meet their obligations to deliver electricity and natural gas to customers. As of March 31, 2013, the future commitments related to these purchase contracts were as follows:

(a)

Total coal commitments for the Columbia and Elm Road Units, including transportation. Fuel procurement for MGE's jointly owned Columbia and Elm Road Units are handled by WPL and WEPCO, respectively, who are the operators of those facilities. 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.

(b)

MGE has several purchase power agreements to help meet future electric supply requirements. Management expects to recover these costs in future customer rates.

Smart Grid Investment Grant - MGE Energy and MGE.

MGE was approved in 2010 by the U.S. Department of Energy (DOE) under the federal stimulus program for a $5.5 million grant for smart grid projects. The DOE grant requires MGE to match the grant funding, bringing the total cost of the projects to more than $11 million. The projects involve the installation of technologies to boost efficiency, enhance service, and improve reliability for customers. The stimulus grant is being used to fund the following projects: advanced metering infrastructure, plug-in hybrid electric vehicles support, and distribution management. As of March 31, 2013, MGE has spent $9.6 million related to these projects and has outstanding agreements to purchase $0.9 million in smart grid related products for the remainder of 2013.

Derivative and Hedging Instruments - MGE Energy and MGE.

Purpose.

As part of its regular operations, MGE enters into contracts, including options, swaps, futures, forwards, and other contractual commitments, to manage its exposure to commodity prices and gas revenues. To the extent that these contracts are derivatives, MGE assesses whether or not the normal purchases or normal sales exclusion applies. For contracts to which this exclusion cannot be applied, MGE Energy and MGE recognize such derivatives in the consolidated balance sheets at fair value. The majority of MGE's derivative activities are conducted in accordance with its electric and gas risk management program, which is approved by the PSCW and limits the volume MGE can hedge with specific risk management strategies. The maximum length of time over which cash flows related to energy commodities can be hedged is four years. If the derivative qualifies for regulatory deferral, the derivatives are marked to fair value and are offset with a corresponding regulatory asset or liability. The deferred gain or loss is recognized in earnings in the delivery month applicable to the instrument. Gains and losses related to hedges qualifying for regulatory treatment are recoverable in gas rates through the PGA or in electric rates as a component of the fuel rules mechanism.

Notional Amounts.

The gross notional volume of open derivatives is as follows:


	March 31, 2013	December 31, 2012
Commodity derivative contracts	331,315 MWh	444,650 MWh
Commodity derivative contracts	1,360,000 Dth	1,980,000 Dth
FTRs	1,085 MW	2,670 MW

Financial Statement Presentation.

MGE Energy and MGE offset fair value amounts recognized for the right to reclaim collateral (a receivable) or the obligation to return collateral (a payable) against fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting agreement.

MGE purchases and sells exchange-traded and over-the-counter options, swaps, and future contracts. These arrangements are primarily entered into to help stabilize the price risk associated with gas or power purchases. These transactions are employed by both MGE's gas and electric segments. Additionally, as a result of the firm transmission agreements that MGE holds on transmission paths in the MISO market, MGE holds FTRs. An FTR is a financial instrument that entitles the holder to a stream of revenues or charges based on the differences in hourly day-ahead energy prices between two points on the transmission grid. The fair values of these instruments are reflected as a regulatory asset/liability depending on whether they are in a net loss/gain position. Depending on the nature of the instrument, the gain or loss associated with these transactions will be reflected as cost of gas sold, fuel for electric generation, or purchased power expense in the delivery month applicable to the instrument. At March 31, 2013, and December 31, 2012, the fair value of exchange traded derivatives and FTRs exceeded their cost basis by $1.5 million and $0.3 million, respectively.

MGE is a party to a ten-year purchased power agreement that provides MGE with firm capacity and energy during a base term from June 1, 2012, through May 31, 2022. The agreement also allows MGE an option to extend the contract after the base term. The agreement is accounted for as a derivative contract and is recognized at its fair value on the consolidated balance sheet. However, the derivative qualifies for regulatory deferral and is recognized with a corresponding regulatory asset or liability depending on whether the fair value is in a loss or gain position. The fair value of the contract at March 31, 2013, and December 31, 2012, reflects a loss position of $70.7 million and $72.6 million, respectively. The actual fuel cost will be recognized in purchased power expense in the month of purchase.

The following table summarizes the fair value of the derivative instruments on the consolidated balance sheet. All derivative instruments in this table are presented on a gross basis and are calculated prior to the netting of instruments with the same counterparty under a master netting agreement as well as the netting of collateral. For financial statement purposes, MGE Energy and MGE have netted instruments with the same counterparty under a master netting agreement as well as the netting of collateral.

MGE's commodity derivative contracts, FTRs, and ten-year PPA are subject to regulatory deferral. These derivatives are marked to fair value and are offset with a corresponding regulatory asset or liability. Realized gains and losses are deferred on the consolidated balance sheet and are recognized in earnings in the delivery month applicable to the instrument. As a result of the above described treatment, there are no unrealized gains or losses that flow through earnings.

The ten-year PPA has a provision that may require MGE to post collateral if MGE's debt rating falls below investment grade (i.e., below BBB-). The amount of collateral that it may be required to post varies from $20.0 million to $40.0 million, depending on MGE's nominated capacity amount. As of March 31, 2013, no collateral has been posted. Certain counterparties extend MGE a credit limit. If MGE exceeds these limits, the counterparties may require collateral to be posted. As of March 31, 2013, and December 31, 2012, no counterparties were in a net liability position.

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, and it monitors these counterparties on an ongoing basis to mitigate nonperformance risk in its portfolio. As of March 31, 2013, no counterparties have defaulted.

Rate Matters - MGE Energy and MGE.

Rate Proceedings.

On April 15, 2013, MGE applied with the PSCW for authority to freeze electric and natural gas rates at 2013 levels for 2014. The application includes a request for categorizing 100% of the cost of the Columbia scrubber construction project as AFUDC. The plan includes a request for deferral of increases in ATC and MISO Schedule 26 fees. In addition, MGE is requesting that approximately $6.2 million pertaining to a fuel rule surplus credit be offset against MGE's increased costs. The fuel credit will accrue interest at MGE's weighted cost of capital during 2013, and the requested treatment of the credit will contribute to the overall rate freeze for 2014.

On December 14, 2012, the PSCW authorized MGE to increase 2013 rates for retail electric customers by 3.8% or $14.9 million and to increase gas rates by 1.0% or $1.6 million. The change in retail electric rates was driven by costs for new environmental equipment at Columbia, final construction costs for the Elm Road Units, transmission reliability enhancements, and purchased power costs. The authorized return on common stock equity remains unchanged at 10.3%.

On December 15, 2011, under a limited reopener of MGE's last rate order, the PSCW authorized MGE to increase 2012 rates for retail electric customers by 4.3% or $15.7 million and to increase gas rates by 0.3% or $0.6 million. The change in retail electric rates was driven by MGE's electric fuel and purchased power costs, increased transmission costs, an update to the Elm Road Units' costs, and an increase for energy efficiency programs. The PSCW also approved deferral of CSAPR costs.

Fuel Rules.

Fuel rules require the PSCW and Wisconsin utilities to defer electric fuel-related costs that fall outside a symmetrical cost tolerance band around the amount approved for a utility in its most recent base rate proceedings. Any over/under recovery of the actual costs is determined on an annual basis and will be adjusted in future billings to electric retail customers. The fuel rules bandwidth is currently set at plus or minus 2%. Under fuel rules, MGE would defer costs, less any excess revenues, if its actual electric fuel costs exceeded 102% of the electric fuel costs allowed in its latest rate order. Excess revenues are defined as revenues in the year in question that provide MGE with a greater return on common equity than authorized by the PSCW in MGE's latest rate order. Conversely, MGE is required to defer the benefit of lower costs if actual electric fuel costs were less than 98% of the electric fuel costs allowed in that order. As of March 31, 2013, MGE did not defer any electric fuel-related savings/costs that are outside the range authorized by the PSCW.

Purchased Gas Adjustment Clause.

MGE's natural gas rates are subject to a fuel adjustment clause designed to recover or refund the difference between the actual cost of purchased gas and the amount included in rates. Differences between the amounts billed to customers and the actual costs recoverable are deferred and recovered or refunded in future periods by means of prospective monthly adjustments to rates. At March 31, 2013, MGE had over collected $5.3 million, recorded in other current liabilities on the consolidated balance sheet. At December 31, 2012, MGE had under collected $0.1 million, recorded in other current assets on the consolidated balance sheet.

11.

Fair Value of Financial Instruments - MGE Energy and MGE.

Fair value is defined as the price that would be received to sell an asset or would be 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.

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

Fair Value of Financial Assets and Liabilities Recorded at the Carrying Amount.

At March 31, 2013, and December 31, 2012, the carrying amount of cash and cash equivalents approximates fair market value due to the short maturity of those investments and obligations. The estimated fair market value of MGE Energy's and MGE's long-term debt is based on quoted market prices for similar financial instruments at March 31, 2013, and December 31, 2012. Since the long-term debt is not traded in an active market, it is classified as Level 2. The estimated fair market value of MGE Energy's and MGE's financial instruments are as follows:

No transfers were made in or out of Level 1 or Level 2 for the three months ended March 31, 2013.

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

Derivatives include exchange-traded derivative contracts, over-the-counter transactions, 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 derivative contracts are valued using quoted market pricing in markets with insufficient volumes and are therefore classified as Level 3. Transactions done with an over-the-counter party are on inactive markets and are therefore classified as Level 3. These transactions are valued based on quoted prices from markets with similar exchange traded transactions. 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.

The ten-year purchased power agreement (see Footnote 9) was valued using an internally-developed pricing model and therefore is classified as Level 3. The model projects future market energy prices and compares those prices to the projected power costs to be incurred under the contract. Inputs to the model require significant management judgment and estimation. Future energy prices are based on a forward power pricing curve using exchange-traded contracts in the electric futures market, where such exchange-traded contracts exist, and upon calculations based on forward gas prices, where such exchange-traded contracts do not exist. A basis adjustment is applied to the market energy price to reflect the price differential between the market price delivery point and the counterparty delivery point. The historical relationship between the delivery points is reviewed and a discount (below 100%) or premium (above 100%) is derived. This comparison is done for both peak times when demand is high and off peak times when demand is low. If the basis adjustment is lowered, the fair value measurement will decrease and if the basis adjustment is increased, the fair value measurement will increase.

The projected power costs anticipated to be incurred under the purchased power agreement are determined using many factors, including historical generating costs, future prices, and expected fuel mix of the counterparty. An increase in the projected fuel costs would result in a decrease in the fair value measurement of the purchased power agreement. A significant input that MGE estimates is the counterparty's fuel mix in determining the projected power cost. MGE also considers the assumptions that market participants would use in valuing the asset or liability. This consideration includes assumptions about market risk such as liquidity, volatility, and contract duration. The fair value model uses a discount rate that incorporates discounting, credit, and model risks.

This model is prepared by members of MGE's Energy Supply group. It is reviewed on a quarterly basis by management in Energy Supply and Finance to review the assumptions, inputs, and fair value measurements.

The following table presents the significant unobservable inputs used in the pricing model.


Significant Unobservable Inputs		Model Input
Basis adjustment:
On peak		97.1 %
Off peak		96.0 %
Counterparty fuel mix:
Internal generation		50 % - 70 %
Purchased power		50 % - 30 %

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 consolidated 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. The notional investments are based upon observable market data, however, since the deferred compensation obligations themselves are not exchanged in an active market, they are classified as Level 2.

The following table summarizes the changes in Level 3 assets and liabilities measured at fair value on a recurring basis for both MGE Energy and MGE.

New Accounting Pronouncements - MGE Energy and MGE.

Presentation of Comprehensive Income.

In February 2013, the FASB issued authoritative guidance within the Codification's Comprehensive Income topic that provides guidance on the reporting of amounts reclassified out of accumulated other comprehensive income. Reclassification adjustments will be presented either on the financial statement where income is presented or as a separate disclosure in the notes to the financial statements. This authoritative guidance became effective January 1, 2013. The authoritative guidance had no effect on our financial statement presentation or notes to the financial statements.

Disclosures about Offsetting Assets and Liabilities.

In December 2011, the FASB issued authoritative guidance within the Codification's Balance Sheet topic that provides guidance on disclosures about offsetting assets and liabilities. The new disclosure requirements mandate that entities disclose both gross and net information for instruments and transactions eligible for offset in the balance sheet as well as instruments and transactions subject to a master netting arrangement. In addition, the standard requires disclosure of collateral received and posted in connections with a master netting arrangement. On January 31, 2013, the FASB issued additional authoritative guidance which clarified the scope of disclosures about offsetting assets and liabilities. The revised guidance limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. This authoritative guidance became effective January 1, 2013. The authoritative guidance did not have a financial impact, but required additional disclosures. See Footnote 9 for additional information.

Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date.

In February 2013, the FASB issued authoritative guidance within the Codification's Balance Sheet topic that provides guidance on the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. This authoritative guidance will become effective January 1, 2014. The authoritative guidance will not have a financial or disclosure impact.

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

General

MGE Energy is an investor-owned public utility holding company operating through subsidiaries in five business segments:

Regulated electric utility operations, conducted through MGE,

Regulated gas utility operations, conducted through MGE,

Nonregulated energy operations, conducted through MGE Power and its subsidiaries,

Transmission investments, representing our equity investment in ATC, and

All other, which includes corporate operations and services.

Our principal subsidiary is MGE, which generates and distributes electric energy, distributes natural gas, and represents a majority portion of our assets, liabilities, revenues, and expenses. MGE generates and distributes electricity to approximately 140,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and distributes natural gas to approximately 145,000 customers in the Wisconsin counties of Columbia, Crawford, Dane, Iowa, Juneau, Monroe, and Vernon.

Our nonregulated energy operations own interests in electric generating capacity that is leased to MGE. The ownership/leasing structure was adopted under applicable state regulatory guidelines for MGE's participation in these generation facilities, consisting principally of a stable return on the equity investment in the new generation facilities over the term of the related leases. The nonregulated energy operations include an ownership interest in two coal-fired generating units in Oak Creek, Wisconsin and a partial ownership of a cogeneration project on the UW-Madison campus. A third party operates the units in Oak Creek, and MGE operates the cogeneration project. Due to the nature of MGE's participation in these facilities, the results of our nonregulated operations are also consolidated into MGE's consolidated financial position and results of operations under applicable accounting standards.

Overview

Our primary focus today and for the foreseeable future is our core utility customers at MGE as well as creating long-term value for our shareholders. MGE continues to face the challenge of providing its customers with reliable power at competitive prices. MGE meets this challenge by investing in more efficient generation projects, including renewable energy sources. In the future, MGE will continue to focus on growing earnings while controlling operating and fuel costs. MGE will continue to maintain safe and efficient operations in addition to providing customer value. We believe it is critical to maintain a strong credit standing consistent with financial strength in MGE as well as the parent company in order to accomplish these goals.

We earn our revenue and generate cash from operations by providing electric and natural gas utility services, including electric power generation and electric power and gas distribution. The earnings and cash flows from the utility business are sensitive to various external factors, including:

Weather, and its impact on customer sales of electricity and gas,

Economic conditions, including current business activity and employment and their impact on customer demand,

Regulation and regulatory issues, and their impact on the timing and recovery of costs,

Energy commodity prices,

Equity price risk pertaining to pension related assets,

Credit market conditions, including interest rates and our debt credit rating,

Environmental laws and regulations, including adopted and pending environmental rule changes,

Construction risk in connection with the Columbia environmental project,

and other factors listed in "Item 1A. Risk Factors" in our 2012 Annual Report on Form 10-K.

For the three months ended March 31, 2013, MGE Energy's earnings were $22.6 million or $0.98 per share compared to $16.0 million or $0.69 per share for the same period in the prior year. MGE's earnings for the three months ended March 31, 2013, were $15.7 million compared to $10.1 million for the same period in the prior year.

MGE Energy's income was derived from our business segments as follows:


		Three Months Ended March 31,
(In thousands)		Three Months Ended March 31,
Business Segment:		2013		2012
Electric Utility	$	7,016	$	5,431
Gas Utility		8,976		4,933
Nonregulated Energy		5,143		4,518
Transmission Investments		1,425		1,332
All Other		24		(166)
Net Income	$	22,584	$	16,048

Our net income during the three months ended March 31, 2013, primarily reflects the effects of the following factors:

A 4.5% increase in retail electric revenues, driven by a 6.9% increase in residential customer demand.

A 31.8% increase in gas sales reflecting higher customer demand due to a colder winter compared to the same period in the prior year. Heating degree days (a measure for determining the impact of weather during the heating season) increased by 38% compared to the prior period.

During the first three months of 2013, the following events occurred:

Columbia Environmental Project: In early 2011, the PSCW authorized the construction of air emission reduction systems and associated equipment on Columbia Units 1 and 2. MGE's estimated share of the capital expenditures required to complete this project will be approximately $140 million. As of March 31, 2013, MGE has accumulated $78.8 million (excluding carrying costs) related to its share of the project, which is reflected in the Construction Work in Progress balance on MGE Energy's and MGE's consolidated balance sheets. Of this amount, MGE has accumulated $18.8 million in 2013. MGE has recognized $0.5 million (after tax) in AFUDC equity related to this project for the three months ended March 31, 2013.

Smart Grid Investment Grant: MGE was approved in 2010 by the U.S. Department of Energy (DOE) under the federal stimulus program for a $5.5 million grant for smart grid projects. The DOE grant requires MGE to match the grant funding, bringing the total cost of the projects to more than $11 million. The projects involve the installation of technologies to boost efficiency, enhance service, and improve reliability for customers. The stimulus grant is being used to fund the following projects: advanced metering infrastructure, plug-in hybrid electric vehicles support, and distribution management. As of March 31, 2013, MGE has spent $9.6 million related to these projects. Of this amount, $1.2 million was incurred during the three months ended March 31, 2013. MGE also has outstanding agreements to purchase $0.9 million in smart grid related products for the remainder of 2013.

In the near term, several items may affect us, including:

Rate Filing: On April 15, 2013, MGE applied with the PSCW for authority to freeze electric and natural gas rates at 2013 levels for 2014. The application includes a request for categorizing 100% of the cost of the Columbia scrubber construction project as AFUDC. The plan includes a request for deferral of increases in ATC and MISO Schedule 26 fees. In addition, MGE is requesting that approximately $6.2 million pertaining to a fuel rule surplus credit be offset against MGE's increased costs. The fuel credit will accrue interest at MGE's weighted cost of capital during 2013, and the requested treatment of the credit will contribute to the overall rate freeze for 2014.

Environmental Initiatives: There are proposed legislation, rules, and initiatives involving matters related to air emissions, water effluent, hazardous materials, and greenhouse gases, all of which affect generation plant capital expenditures and operating costs as well as future operational planning. Such legislation and rulemaking could significantly affect the costs of owning and operating fossil-fueled generating plants, such as Columbia and Elm Road, from which we derive approximately 43% of our electric generating capacity. We would expect to seek and receive recovery of any such costs in rates; however, it is difficult to estimate the amount of such costs due to the uncertainty as to the timing and form of the legislation and rules, and the scope and time of the recovery of costs in rates. In addition, MGE is involved in claims surrounding the alleged failure, among other things, to obtain necessary air permits and implement necessary emission controls associated with past activities at Columbia. MGE and the other co-owners are defending against these claims. See Columbia discussion in Footnote 8.a. in Notes to Consolidated Financial Statements.

Columbia Environmental Project: MGE's share of the capital expenditures associated with the Columbia environmental project will be approximately $49 million for the remainder of 2013 million and $12 million in 2014. We intend to fund any remaining capital commitments with funds generated from normal operations and the issuance of long-term and short-term debt.

General economic conditions: Economic conditions both inside and outside our service area are expected to continue to affect the level of demand for our utility services and may affect the collection of our accounts receivable and the creditworthiness of counterparties with whom we do business. We have in place lines of credit aggregating $104.5 million for MGE Energy (including MGE) and $64.5 million for MGE to address our liquidity needs.

The following discussion is based on the business segments as discussed in Footnote 13.

Three Months Ended March 31, 2013 and 2012

Electric Utility Operations - MGE Energy and MGE

Electric sales and revenues

The following table compares MGE's electric revenues and electric kWh sales by customer class for each of the periods indicated:


		Revenues Three Months Ended March 31,				Sales (kWh) Three Months Ended March 31,
(in thousands)		Revenues Three Months Ended March 31,				Sales (kWh) Three Months Ended March 31,
(in thousands)		2013		2012	% Change	2013	2012	% Change

Total	$	93,494	$	89,936	4.0 %	806,012	801,234	0.6 %

Electric operating revenues increased $3.6 million or 4.0% for the three months ended March 31, 2013, due to the following:


(In millions)
Rate changes	$	4.0
Sales to the market		(0.2)
Adjustments to revenues		(0.2)
Total	$	3.6

Rate changes. Rates charged to retail customers for the three months ended March 31, 2013, were 4.4% or $4.0 million higher than those charged during the same period in the prior year.

In December 2012, the PSCW authorized MGE to increase 2013 rates for retail electric customers by 3.8% or $14.9 million. The increase in retail electric rates is driven by costs for new environmental equipment at Columbia, final construction costs for the Elm Road Units, transmission reliability enhancements, and purchased power costs.

Sales to the market. Sales to the market represent wholesale sales made to third parties who are not ultimate users of the electricity. These sales may include spot market transactions on the markets operated by MISO and PJM. These sales may also include bilateral sales to other utilities or power marketers. Generating Units are dispatched by MISO based on cost considerations as well as reliability of the system. Sales to the market typically occur when MGE has more generation and purchases online than is needed for its own system demand. The excess electricity is then sold to others in the market. For the three months ended March 31, 2013, market volumes increased compared to the same period in the prior year, reflecting increased opportunities for sales; however, market settlement resulted in lower revenue per kWh for the three months ended March 31, 2013, reflecting lower market prices.

Adjustments to revenues. The adjustments to revenues amount includes the elimination of carrying costs for the Elm Road Units and WCCF that were collected in electric rates, which are recognized as nonregulated energy operating revenues in our Nonregulated Energy Operations segment.

Electric fuel and purchased power

The expense for fuel for electric generation increased $1.9 million or 21.6% during the three months ended March 31, 2013, compared to the same period in the prior year. Internal electric generated volume delivered to the system increased 35.4% which resulted in $2.8 million of increased expense, reflecting higher generation at Columbia. This increase was offset by a decrease in internal electric generation costs of $0.9 million as a result of a 10.2% decrease in the per-unit cost (largely due to lower natural gas prices).

Purchased power expense decreased $1.3 million during the three months ended March 31, 2013, compared to the same period in the prior year. A 29.4% decrease in the volume of purchased power from third parties lowered expense by $5.7 million, which was offset by a $4.4 million or 31.9% increase in the per-unit cost of purchased power.

Electric operating and maintenance expenses

Electric operating and maintenance expenses decreased $0.4 million during the three months ended March 31, 2013, compared to the same period in 2012. The following changes contributed to the net change:


(In millions)
Decreased administrative and general costs	$	(0.7)
Decreased customer service costs		(0.3)
Decreased other costs		(0.1)
Increased transmission costs		0.7
Total	$	(0.4)

For the three months ended March 31, 2013, decreased administrative and general costs are primarily due to decreased pension costs and increased transmission costs are primarily due to an increase in transmission reliability enhancements.

(In millions)
Gas deliveries	$	18.7
Transportation and other effects		0.1
Gas costs/rates		(3.4)
Total	$	15.4

Retail gas deliveries. For the three months ended March 31, 2013, retail gas deliveries increased 33.2% compared to the same period in 2012 as a result of colder weather during the winter months compared to milder weather in the prior year.

Gas costs/rates. The average retail rate per therm for the three months ended March 31, 2013, decreased 4.7% compared to the same period in 2012, reflecting lower natural gas commodity costs.

Cost of gas sold

For the three months ended March 31, 2013, cost of gas sold increased by $9.8 million, compared to the same period in the prior year. The volume of gas purchased increased 33.0%, which resulted in $11.4 million of increased expense. However, the cost per therm of natural gas decreased 3.5%, which resulted in $1.6 million of decreased expense.

Gas operating and maintenance expenses

Gas operating and maintenance expenses decreased by $0.7 million for the three months ended March 31, 2013, compared to the same period in 2012. The following changes contributed to the net change:

MGE Energy's and MGE's Capital Requirements

MGE Energy's and MGE's liquidity are primarily affected by their capital requirements. During the three months ended March 31, 2013, capital expenditures for MGE Energy and MGE totaled $29.2 million, which included $28.7 million of capital expenditures for utility operations.

In early 2011, the PSCW authorized the construction of air emission reduction systems and associated equipment on Columbia Units 1 and 2. MGE's estimated share of the capital expenditures required to complete this project will be approximately $140 million. MGE's share of the capital expenditures associated with the Columbia environmental project will be approximately $49 million for the remainder of 2013 and $12 million in 2014. During the three months ended March 31, 2013, MGE had incurred $18.8 million (excluding carrying costs) in construction expenditures at Columbia related to the project. MGE has recognized $0.5 million (after tax) in AFUDC equity related to this project for the three months ended March 31, 2013.

Credit Ratings

MGE Energy's and MGE's access to the capital markets, including, in the case of MGE, the commercial paper market, and their respective financing costs in those markets, may depend on the credit ratings of the entity that is accessing the capital markets.

None of MGE Energy's or MGE's borrowing is subject to default or prepayment as a result of a downgrading of credit ratings, although a downgrading of MGE's credit ratings could increase fees and interest charges under both MGE Energy's and MGE's credit agreements.

Environmental Matters

The following discussion is limited to updates or developments in environmental matters that occurred during the three months ended March 31, 2013. Further discussion of environmental matters is included in MGE Energy's and MGE's 2012 Annual Report on Form 10-K and Footnote 8.a. of Notes to Consolidated Financial Statements in this Report.

Vacation of EPA's Cross State Air Pollution Rule (CSAPR) and Reinstatement of the Clean Air Interstate Rule (CAIR)

In 2005, EPA promulgated the Clean Air Interstate Rule (CAIR) to reduce ozone and fine particulate matter emissions by reducing nitrogen oxide (NO_x) and sulfur dioxide (SO₂) emissions. NO_x and SO₂ interact in the atmosphere to form ambient ozone from NO_x and fine particulate matter pollution from NO_x and SO₂. The CAIR generally requires NO_x and SO₂ emission reductions from fossil fuel-fired EGUs (25 MW or greater) in the eastern half of the United States in two phases and includes a regional cap-and-trade system. The first phase (currently in place) requires annual regional emission reductions from 2003 levels of 55% for NO_x and 40% for SO₂. The second phase (beginning in 2015) reduces regional NO_x and SO₂ emissions further from 2003 levels to 65% and 70%, respectively. MGE owns or has partial ownership in several generation units currently subject to the CAIR: Blount, Columbia, Elm Road Units, and its combustion turbines located in West Marinette and Fitchburg.

MGE is currently in compliance with the CAIR Phase I requirements. MGE will be able to meet Phase II NO_x emissions reductions through using our NO_x allowances provided through the rule, and we will meet Phase II SO₂ emissions reductions through installation of pollution controls. New SO₂ controls at Columbia are already underway and are planned to be completed by mid 2014. MGE expects that any costs incurred to meet Phase II of the CAIR will be fully recoverable through rates. MGE will monitor the Supreme Court's response to the CSAPR appeals and any subsequent actions by the EPA to continue to evaluate potential impacts to our operations.

Columbia

Columbia is a coal-fired generating station operated by WPL in which WPL, WPSC, and MGE have ownership interests. In December 2009, the EPA sent a Notice of Violation (NOV) to MGE as one of the co-owners of Columbia. The NOV alleges that WPL and the Columbia co-owners failed to comply with appropriate pre-construction review and permitting requirements and, as a result, violated the Prevention of Significant Deterioration program requirements, Title V Operating Permit requirements of the CAA, and the Wisconsin SIP. In September 2010, the Sierra Club filed a civil lawsuit against WPL alleging violations of the CAA at Columbia and other Wisconsin facilities operated by WPL. In April 2013, WPL, as operator, along with the other owners of Columbia (MGE and WPS), entered into a consent decree with the EPA and the Sierra Club to resolve these claims, while admitting no liability. One of the requirements of the consent decree requires installation of a SCR system at Columbia Unit 2 by December 31, 2018. Based on a preliminary estimate received by WPL, MGE’s share of the projected cost for construction of the SCR system at Columbia is approximately $50-$60 million. The consent decree has been lodged with, and is subject to approval by, the Court, which could occur in the second quarter of 2013. See Footnote 8.a. for additional information regarding these matters.

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, and equity returns. MGE currently has no exposure to foreign currency risk. MGE manages some risk exposure through risk management policies and the use of derivative instruments. MGE's risk management policy prohibits speculative trading transactions.

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 peaking power plants and, in many cases, the cost of purchased power is tied to the cost of natural gas. MGE bears 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.

The fuel rules require the PSCW and Wisconsin utilities to defer electric fuel-related costs that fall outside a symmetrical cost tolerance band. Any over/under recovery of the actual costs is determined on an annual basis and will be adjusted in future billings to electric retail customers. Under the electric fuel rules, MGE is required to defer the benefit of lower costs if the actual electric fuel rules costs fall outside the lower end of the range and would defer costs, less any excess revenues, if the actual electric fuel rules costs exceeded the upper end of the range. Excess revenues are defined as revenues in the year in question that provide MGE with a greater return on common equity than authorized by the PSCW in MGE's latest rate order. The range is defined by the PSCW and has been modified throughout the years based on market conditions and other relevant factors. Currently, MGE is subject to a plus or minus 2% range. MGE assumes the risks and benefits of variances that are within the cost tolerance band. For 2013, fuel and purchased power costs included in MGE's base fuel rates are $106.1 million. See Footnote 10.b. for additional information.

MGE recovers the cost of natural gas in its gas segment through the purchased gas adjustment clause (PGA). Under the PGA, MGE is able to pass through to its gas customers the cost of gas.

MGE also reduces price risk caused by market fluctuations via physical contracts and financial derivative contracts, including futures, swaps, options, forwards, and other contractual commitments. The maximum length of time over which cash flows related to energy commodities can be hedged under applicable PSCW approvals is four years.

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. MGE also holds FTRs, which are used to hedge the risk of increased transmission congestion charges. At March 31, 2013, the fair value of these instruments exceeded their cost basis by $1.5 million. Under the PGA clause and electric fuel rules, MGE may include in the costs of fuel (natural gas or power) the costs and benefits of the aforementioned fuel price risk management tools. Because these costs/benefits are recoverable, the related unrealized loss/gain has been deferred on the consolidated balance sheet as a regulatory asset/liability.

MGE has also entered into a ten-year purchased power agreement that provides MGE with firm capacity and energy that began on June 1, 2012, and ends on May 31, 2022 (the "base term"). The agreement also allows MGE the option to extend the contract after the base term. The agreement is a derivative contract and is recognized at its fair value on the consolidated balance sheet. However, the derivative qualifies for regulatory deferral and is recognized with a corresponding regulatory asset or liability depending on whether the fair value is in a loss or gain position. The fair value of the contract at March 31, 2013, reflects a loss position of $70.7 million.

Interest Rate Risk

Both MGE Energy and MGE may 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 expenses related to these liabilities.

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 include 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. As of March 31, 2013, no counterparties have defaulted.

MGE is obligated to provide service to all electric and gas customers within its respective franchised territories. MGE's franchised electric territory includes a 316 square-mile area in Dane County, Wisconsin, and MGE's franchised gas territory includes a service area covering 1,631 square miles in Wisconsin. Based on results for the year ended December 31, 2012, no one customer constituted more than 10% of total operating revenues for MGE Energy and MGE. 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 relatively strong economy in its service territory.

Item 4. Controls and Procedures.

During the first quarter of 2013, each registrant'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 that registrant, including its subsidiaries, is accumulated and made known to that registrant's management, including these officers, by other employees of that registrant 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, the registrants do not control or manage certain of their unconsolidated entities and thus, their access and ability to apply their procedures to those entities is more limited than is the case for their consolidated subsidiaries.

As of March 31, 2013, each registrant's principal executive officer and principal financial officer concluded that its disclosure controls and procedures were effective. Each registrant intends to strive continually to improve its disclosure controls and procedures to enhance the quality of its financial reporting.

During the quarter ended March 31, 2013, there were no changes in either registrant's internal controls over financial reporting that materially affected, or are reasonably likely to affect materially, that registrant's internal control over financial reporting.

* Under the Stock Plan, common stock shares deliverable to plan participants may be either newly issued shares or shares purchased on the open market, as determined from time to time by MGE Energy. In June 2009, MGE Energy switched to using open market purchases to provide shares to meet obligations to participants in the Stock Plan. The shares are purchased on the open market through a securities broker-dealer and then are reissued under the Stock Plan as needed to meet share delivery requirements. The volume and timing of share repurchases in the open market depends upon the level of dividend reinvestment and optional share purchases being made from time to time by plan participants. As a result, there is no specified maximum number of shares to be repurchased and no specified termination date for the repurchases. All shares issued through the Stock Plan, whether newly issued or reissued following open market purchases, are issued and sold pursuant to a registration statement that was filed with the SEC and is currently effective.
