Management's Discussion and Analysis of Financial Condition and Results of Operations in this report, and Item 8. Financial Statements and Supplementary Data – Note 17, as updated by Part I, Item 1. Financial Statements – Note 7 in this report, and (b) other factors discussed herein and in other filings made by that registrant with the SEC.

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, Inc., and Madison Gas and Electric Company

Notes to Consolidated Financial Statements (unaudited)

September 30, 2017

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 accounting 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 2016 Annual Report on Form 10-K (the 2016 Annual Report on Form 10-K).

Prior to December 1, 2016, MGE Transco was jointly owned by MGE Energy and MGE. MGE's ownership interest in MGE Transco declined below a majority in July 2016. As a result of the change in majority ownership in MGE Transco in July 2016, MGE deconsolidated MGE Energy's proportionate share of the equity in MGE Transco. The change in consolidation was applied prospectively by reducing its investment and noncontrolling interest on MGE's consolidated financial statements. On December 1, 2016, MGE's ownership interest in MGE Transco was transferred to MGE Energy. See Footnote 3 for further discussion.

The accompanying consolidated financial statements as of September 30, 2017, and for the three and nine 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 the 2016 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 54 through 104 of the 2016 Annual Report on Form 10-K.

Equity and Financing Arrangements - MGE Energy.

Common Stock.

MGE Energy sells shares of its common stock through its Stock Plan. Those shares may be newly issued shares or shares that MGE Energy has purchased in the open market for resale to participants in the Stock Plan. All sales under the Stock Plan are covered by a shelf registration statement that MGE Energy filed with the SEC. For both the three and nine months ended September 30, 2017 and 2016, MGE Energy did not issue any new shares of common stock under the Stock Plan.

Dilutive Shares Calculation.

MGE Energy does not have any stock option or stock award programs or any dilutive securities.

Long-term Debt - MGE Energy and MGE.

On January 13, 2017, MGE issued $40 million of 3.76% senior unsecured notes due January 15, 2052. MGE used the net proceeds from the sale of senior notes to refinance $30 million of medium-term notes, which matured in January 2017, and assist with the financing of additional capital expenditures. The long-term debt carries an interest rate of 3.76% per annum over its 35-year term. The covenants of this debt are substantially consistent with MGE's existing unsecured long-term debt.

On October 2, 2017, MGE issued $30 million of 3.11% senior unsecured notes due October 1, 2027. MGE will use the net proceeds from the sale of senior notes to cover capital expenditures and other corporate obligations. The long-term debt carries an interest rate of 3.11% per annum over its 10-year term. The covenants of this debt are substantially consistent with MGE's existing unsecured long-term debt.

Investment in ATC and ATC Holdco - 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 as required by Wisconsin law. That interest is presently held by MGE Transco, which, as of December 1, 2016, is owned solely by MGE Energy. ATC Holdco was formed by several members of ATC, including MGE Energy, to pursue electric transmission development and investments outside of Wisconsin. The ownership interest in ATC Holdco is held by MGEE Transco, a wholly-owned subsidiary of MGE Energy.

MGE Transco and MGEE Transco have accounted for their investment in ATC and ATC Holdco, respectively, under the equity method of accounting. Equity earnings from investments are recorded as "Other income" on MGE Energy's consolidated statements of income. For the three and nine months ended September 30, 2017 and 2016, MGE Transco recorded the following:


		Three Months Ended				Nine Months Ended
		September 30,				September 30,
(In thousands)		2017		2016		2017		2016
Equity earnings from investment in ATC	$	2,338	$	2,023	$	7,432	$	6,023
Dividends from ATC^(a)		2,070		1,486		4,070		4,214
Capital contributions to ATC		710		888		3,018		1,598

(a)

As of December 31, 2016, MGE Transco recorded a $2.1 million receivable from ATC for a cash dividend received in January 2017.

ATC Holdco's activities commenced in late December 2016 and had an immaterial impact on results of operations, cash flows, and financial condition.

At September 30, 2017, and December 31, 2016, MGE Transco held a 3.6% ownership interest in ATC. At September 30, 2017, and December 31, 2016, MGEE Transco held a 4.4% and 4.0% ownership interest in ATC Holdco, respectively.

In June 2016, the PSCW required MGE to transfer its interest in ATC to MGE Energy, which was to be completed by December 31, 2022. The requirement arose in the context of requests for regulatory approvals by several owners of ATC in connection with a reorganization of ATC. MGE's ownership interest in ATC, held through MGE Transco, was transferred net of deferred tax liabilities to MGE Energy by way of a dividend in kind of $15.8 million as of December 1, 2016. As a result of the transfer, MGE's ownership interest in MGE Transco was completely eliminated in favor of MGE Energy. The change had no effect on MGE Energy's consolidated financial statements.

ATC's summarized financial data for the three and nine months ended September 30, 2017 and 2016, is as follows:


		Three Months Ended				Nine Months Ended
		September 30,				September 30,
(In thousands)		2017		2016		2017		2016
Operating revenues	$	171,123	$	158,126	$	522,402	$	476,591

Earnings before members' income taxes	$	58,583	$	54,359	$	192,713	$	164,406

MGE receives transmission and other related services from ATC. During the three and nine months ended September 30, 2017, MGE recorded $7.3 million and $21.9 million, respectively, for transmission services received compared to $7.4 million and $22.1 million for the comparable periods in 2016. MGE also provides a variety of operational, maintenance, and project management services for ATC, which is reimbursed by ATC. As of September 30, 2017, and December 31, 2016, MGE had a receivable due from ATC of $0.1 million.

Taxes - MGE Energy and MGE.

MGE Energy's effective income tax rate for the three months ended September 30, 2017 and 2016, was 36.9% and 36.1%, respectively. MGE's effective income tax rate for the three months ended September 30, 2017 and 2016, was 36.7% and 36.0%, respectively. For both MGE Energy and MGE, the increase in the effective tax rate is due in part to lower estimated federal tax credits.

MGE Energy's effective income tax rate for the nine months ended September 30, 2017 and 2016, was 36.6% and 36.4%, respectively. MGE's effective income tax rate for the nine months ended September 30, 2017 and 2016, was 36.3% and 36.4%, respectively.

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 net periodic benefit costs recognized for the three and nine months ended September 30, 2017 and 2016. A portion of the net periodic benefit cost is capitalized within the consolidated balance sheets.

Share-Based Compensation - MGE Energy and MGE.

Under MGE Energy's Director Incentive Plan and its Performance Unit Plan, non-employee directors and eligible employees 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 January 2017, 4,032 units were granted under the Director Incentive Plan and are subject to a three-year graded vesting schedule. In March 2017, 14,704 units were granted under the Performance Unit Plan and are subject to a five-year graded vesting schedule. On the grant date, MGE Energy and MGE measure the cost of the director or 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 is re-measured quarterly, including at September 30, 2017, as required by applicable accounting standards. Changes in fair value as well as the original grant are recognized as compensation cost. Since this amount is re-measured throughout the vesting period, the compensation cost is subject to variability.

For nonretirement eligible employees under the Performance Unit Plan, 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.

During the three and nine months ended September 30, 2017, MGE recorded $0.3 million and $1.0 million, respectively, in compensation expense as a result of awards under the plans compared to $0.2 million and $2.0 million for the comparable periods in 2016. In January 2017, cash payments of $2.0 million were distributed according to the terms of the awards granted earlier under the plans that had reached their payment dates. No forfeitures of units occurred during the three and nine months ended September 30, 2017 and 2016. At September 30, 2017, $5.1 million of outstanding awards are vested, and of this amount, no cash settlements have occurred.

Commitments and Contingencies.

Environmental - MGE Energy and MGE.

MGE Energy and MGE are subject to frequently changing local, state, and federal regulations concerning air quality, water quality, land use, threatened and endangered species, hazardous materials handling, and solid waste disposal. These regulations affect the manner in which they conduct their operations, the costs of those operations, as well as capital and operating expenditures. Several of these environmental rules are subject to legal challenges, reconsideration and/or other uncertainties. Regulatory initiatives, proposed rules, and court challenges to adopted rules, have the potential to have a material effect on our capital expenditures and operating costs. Management believes compliance costs will be recovered in future rates based on previous treatment of environmental compliance projects. These initiatives, proposed rules, and court challenges include:

•

The EPA's published water effluent limitations guidelines and standards for steam electric power plants, which focus on the reduction of metals and other pollutants in wastewater from new and existing power plants, such as the coal-burning plants at Columbia and the Elm Road Units.

•

The EPA's cooling water intake rules, which require cooling water intake structures at electric power plants, such as our WCCF, Blount, and Columbia 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.

•

Greenhouse Gas (GHG) reduction guidelines and approval criteria established under the Clean Air Act for states to use in developing plans to control GHG emissions from existing fossil fuel-fired electric generating units (EGUs) and systems (the Clean Power Plan, or CPP). Implementation of the rule is expected to have a direct impact on existing coal and natural gas fired generating units, including possible changes in dispatch and additional operating costs. In May 2017, the EPA requested the U.S. Court of Appeals for the D.C. Circuit to put on hold, indefinitely, any ongoing challenges to the rules while the EPA reviews the rule and undertakes any potential rulemaking. In October 2017, the EPA published a proposed rule announcing the EPA's intention to repeal the CPP and has sought public comment on whether to replace the rule, and if so how. Given the pending legal proceedings, and the EPA's recent proposal, the nature and timing of any final requirements to control GHG emissions from existing fossil fuel-fired EGUs is subject to uncertainty. If a rule is implemented substantially in its present form, it is expected to have a material impact on MGE. MGE will continue to monitor developments with this proposed rule.

•

Federal and state air quality regulations impose restrictions on various emissions including emissions of sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and other pollutants, and may require permits for operation of emission sources.

•

The EPA's rule to regulate ambient levels of a pollutant through the Ozone National Ambient Air Quality Standards (NAAQS). The State of Wisconsin has joined a lawsuit filed by several states challenging the EPA's new ozone standard, alleging that the new standard is not attainable and the EPA is not properly considering background levels in setting its ozone attainment levels. Oral arguments in this case were delayed following a request by the EPA. The EPA missed its regulatory deadline to

designate areas as attainment or nonattainment under the 2015 standard. MGE will continue to monitor the EPA's progress on attainment designations to assess potential impacts at our facilities, particularly our Elm Road Units.

•

Rules regulating nitrogen oxide (NO_x) and SO₂ emissions, including the Cross State Air Pollution Rule (CSAPR) and Clean Air Visibility Rule (CAVR). At this time, regulatory obligations, compliance strategies, and costs remain uncertain due to uncertainties surrounding the ongoing implementation of Phase II of CSAPR and the continued legal challenges surrounding CSAPR and CAVR.

•

The EPA's Coal Combustion Residuals Rule, which regulates coal ash as a solid waste, and defines what ash use activities would be considered generally exempt beneficial reuse of coal ash. The rule also regulates landfills, ash ponds, and other surface impoundments for coal combustion residuals by regulating their design, location, monitoring, and operation. Review of our Elm Road Units has indicated that the costs to comply with this rule are not expected to be significant. Columbia's operator has developed a preliminary implementation schedule for meeting the various deadlines spelled out in the rule. Costs at Columbia will be dependent on what is determined during the evaluation stage.

The matters in the bullet points above are discussed further in Footnote 17.c. in the Financial Statements of the 2016 Annual Report on Form 10-K.

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. 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. MGE does not expect the resolution of these matters to have a material adverse effect on its consolidated results of operations, financial condition, or cash flows.

Purchase Contracts - MGE Energy and MGE.

MGE has entered into various commodity supply, transportation, and storage contracts to meet its obligation to deliver electricity and natural gas to customers. Management expects to recover these costs in future customer rates. As of September 30, 2017, the future commitments related to these purchase contracts were as follows:


(In thousands)		2017		2018		2019		2020		2021		Thereafter

(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 is handled by WPL and WEPCO, respectively, who are the operators of those facilities.

(b)

MGE's natural gas transportation and storage contracts require fixed monthly payments for firm supply pipeline transportation and storage capacity. The pricing components of the fixed monthly payments for the transportation and storage contracts are established by FERC but may be subject to change.

(c)

These commitments include market-based pricing.

Other Commitments - MGE Energy.

In May 2017, MGE Energy entered into a subscription agreement to invest in a nonpublic venture capital fund. From time to time, this entity will require capital infusions from its investors. MGE Energy has committed to contribute $5 million in capital for such infusions. The timing of these infusions is dependent on the needs of the investee and is therefore uncertain at this time.

Rate Matters - MGE Energy and MGE.

Rate Proceedings.

In December 2016, the PSCW authorized MGE, effective January 1, 2017, to decrease 2017 rates for retail electric customers by 0.8% or $3.3 million on an annual basis and to increase rates for retail gas customers by 1.9% or $3.1 million on an annual basis. The decrease in retail electric rates is attributable to declining fuel and purchased power costs. The increase in retail gas rates covers costs associated with MGE's natural gas system infrastructure improvements. The authorized return on common stock equity for 2017 is 9.8% based on a capital structure consisting of 57.2% common equity. The PSCW also approved MGE's request to extend the current accounting treatment for transmission related costs through 2018. This accounting treatment allows MGE to reflect any differential between transmission costs reflected in rates and actual costs incurred in its next rate case filing.

In July 2015, the PSCW approved MGE's request to extend the current accounting treatment for transmission related costs through 2016, conditioned upon MGE not filing a base rate case for 2016. MGE did not file a base rate case for 2016.

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 annual fuel proceedings. Any over/under recovery of the actual costs is determined in the following year and is then reflected 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.

In August 2015, the PSCW approved a $0.00256/kWh fuel credit that began on September 1, 2015, and continued throughout 2016. MGE returned $2.6 million of electric fuel-related savings to customers through bill credits during the period from September 1, 2015, through December 31, 2015. MGE returned $8.3 million of electric fuel-related savings during the year ended December 31, 2016.

In July 2016, the PSCW issued a final order in the fuel rules proceedings requiring MGE to refund additional fuel savings realized during 2015 and 2016 to its retail electric customers over a one-month period. In September 2016, MGE returned $15.5 million to customers through bill credits.

In July 2017, the PSCW issued a final order in the fuel rules proceedings requiring MGE to refund $6.0 million of additional fuel savings realized during 2015 and 2016 to its retail electric customers over a one-month period in October 2017.

As of September 30, 2017, MGE has deferred $3.3 million of 2017 fuel savings. The 2017 fuel savings will be subject to the PSCW's annual review of 2017 fuel costs, expected to be completed in 2018.

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. 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, the derivatives are recognized in the consolidated balance sheets at fair value. MGE's financial commodity 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 depending on whether the derivative is in a net loss or net gain position, respectively. 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:


	September 30, 2017	December 31, 2016
Commodity derivative contracts	634,605 MWh	393,395 MWh
Commodity derivative contracts	7,924,500 Dth	4,195,000 Dth
FTRs	3,552 MW	2,251 MW
PPA	2,800 MW	3,250 MW

Financial Statement Presentation.

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 electricity 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 offset with a corresponding 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 September 30, 2017, and December 31, 2016, the fair value of exchange traded derivatives and FTRs exceeded their cost basis by $0.9 million and $1.3 million, respectively.

MGE is a party to a 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 sheets. 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 September 30, 2017, and December 31, 2016, reflects a loss position of $43.1 million and $50.6 million, respectively. The actual 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 sheets. 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, instruments are netted with the same counterparty under a master netting agreement as well as the netting of collateral. As of September 30, 2017, and December 31, 2016, the receivable – margin account balance of $1.5 million and $1.3 million, respectively, is shown net of any collateral posted against derivative positions.

MGE's commodity derivative contracts, FTRs, and 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 sheets 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 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 September 30, 2017, no collateral is required to be, or 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 September 30, 2017, certain counterparties were in a net liability position of less than $0.1 million. As of December 31, 2016, 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 September 30, 2017, no counterparties have defaulted.

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 accounting 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 September 30, 2017, and December 31, 2016, the carrying amount of cash, cash equivalents, and outstanding commercial paper approximates fair market value due to the short maturity of those investments and obligations. The estimated fair market value of long-term debt is based on quoted market prices for similar financial instruments at September 30, 2017, and December 31, 2016. Since long-term debt is not traded in an active market, it is classified as Level 2. The estimated fair market values of financial instruments are as follows:

No transfers were made in or out of Level 1 or Level 2 for the nine months ended September 30, 2017.

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 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 considered unobservable and 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 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. 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.

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


	Model Input
Significant Unobservable Inputs	September 30, 2017	December 31, 2016
Basis adjustment:
On peak	92.4%	91.9%
Off peak	94.2%	93.4%
Counterparty fuel mix:
Internal generation	55% - 75%	55% - 75%
Purchased power	45% - 25%	45% - 25%

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. 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.

MGE's exchange-traded derivative contracts, over-the-counter party transactions, purchased power agreement, and FTRs are subject to regulatory deferral. These derivatives are therefore marked to fair value and are offset in the financial statements with a corresponding regulatory asset or liability.

Joint Plant Ownership - MGE Energy and MGE.

Columbia.

In 2016, MGE and WPL negotiated an amendment to the existing Columbia joint operating agreement, that has been approved by the PSCW, under which MGE will have the option to reduce its obligation to pay certain capital expenditures (other than SCR-related expenditures) at Columbia in exchange for a proportional reduction in MGE's ownership in Columbia. On January 1 of each year, beginning in 2017 and ending June 1, 2020, the ownership percentage will be adjusted, through a partial sale, based on the amount of capital expenditures foregone. In June 2017, the FERC approved the ownership transfer in Columbia, effective January 1, 2017.

During 2016, MGE accrued $14.8 million of 2016 capital expenditures that MGE has forgone as part of the ownership transfer agreement with WPL. As of December 31, 2016, MGE classified $14.8 million of Columbia assets as held-for-sale on the consolidated balance sheets. In January 2017, MGE reduced its ownership interest in Columbia from 22.0% to 20.4% through the partial sale of plant assets to WPL.

During three and nine months ended September 30, 2017, MGE accrued $1.6 million and $6.7 million, respectively, of 2017 capital expenditures that MGE has forgone subject to the ownership transfer agreement. As of September 30, 2017, MGE classified $6.7 million of Columbia assets as held-for-sale on the consolidated balance sheets. The assets recognized as held-for-sale are subject to a partial sale of plant assets to WPL, expected to occur in January 2018.

Adoption of Accounting Principles and Recently Issued Accounting Pronouncements - MGE Energy and MGE.

Revenue from Contracts with Customers.

In May 2014, the FASB issued authoritative guidance within the Codification's Revenue Recognition topic that provides guidance on the recognition, measurement, and disclosure of revenue from contracts with customers. The new standard establishes a five step model for recognizing and measuring revenue from contracts with customers and replaces existing guidance on revenue recognition. The objective of the new standard is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services.

MGE Energy and MGE have been assessing the impact of this guidance on revenue streams within the scope of the new standard. All retail electric and gas revenues are tariff rates approved by the PSCW. Based on our evaluation of the new standard, retail revenues will be recognized within the period in which utility service is provided to the customer and the performance obligation is fulfilled, consistent with our current revenue recognition model. Electric revenues for sales to the market represent wholesale sales made to third parties who are not ultimate users of the electricity. These sales may also include bilateral sales to other utilities or power marketers. Revenues for sales to the market will be recognized when the sale is completed within the market operated by MISO, similar to the recognition under our current revenue recognition model. In addition, revenues from the transportation of gas will continue to be recognized upon the performance of services for the respective customer. Based on our assessment of the new standard, revenue recognition for retail revenues, sales to the market, and transportation of gas will be materially consistent with our current revenue recognition model. However, additional disclosures regarding the nature, amount, timing, and uncertainty of these revenue streams and related cash flows arising from contracts with customers will be required as a result of the new standard. Management continues to analyze newly-released interpretative guidance and assess the related impacts to the current revenue recognition model.

This authoritative guidance will become effective January 1, 2018, and MGE Energy and MGE anticipate adopting the standard upon the effective date. Adoption of this standard is permitted under one of two methods: the full retrospective method or the modified retrospective method. MGE Energy and MGE are continuing to assess the permitted implementation methods and the impact on our financial statements.

Financial Instruments.

In January 2016, the FASB issued authoritative guidance within the Codification's Financial Instruments topic that provides guidance on the recognition and measurement of financial instruments. This authoritative guidance will become effective January 1, 2018, and will require equity investments to be measured at fair value with changes in fair value recognized in net income rather than in other comprehensive income. As a result of this guidance, MGE Energy and MGE will no longer have any other comprehensive income related to equity investments. This standard will be applied using a modified retrospective approach, with a cumulative effect adjustment recorded to opening retained earnings as of the beginning of all prior periods presented. As of September 30, 2017, MGE Energy had $0.4 million and MGE had less than $0.1 million of accumulated other comprehensive income related to equity investments within the scope of this standard.

Leases.

In February 2016, the FASB issued authoritative guidance within the Codification's Leases topic that provides guidance on the classification, recognition, measurement, and disclosure of leases. The new leasing standard establishes that a lease conveys the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Under the new guidance, lessees will be required to recognize all leases with terms greater than one year, including operating leases, on the consolidated balance sheet by recording a right-of-use asset and lease liability. Prior to the authoritative guidance, only capital leases were recognized on the balance sheet by lessees. The new accounting guidance as applied by lessors is materially consistent from that applied under current GAAP.

Management has begun utilizing a bottoms-up approach to analyze the impact of the standard on our lease portfolio. MGE Energy and MGE have been reviewing current accounting policies and procedures to identify potential differences in accounting treatment that would result from applying the requirements of the new standard to our existing lease portfolio. In addition, we are identifying appropriate changes to our business processes, systems, and controls to support recognition and disclosure requirements under the new standard. This authoritative guidance will become effective January 1, 2019, with early adoption permitted. MGE Energy and MGE anticipate adopting the standard upon the effective date. The new leasing standard requires entities to recognize and measure leases at the beginning of the earliest comparative period presented using a modified retrospective approach. MGE Energy and MGE are currently assessing the impact this pronouncement will have on our financial statements.

Restricted Cash.

In November 2016, the FASB issued authoritative guidance within the Codification's Statement of Cash Flows topic that provides guidance on the classification and presentation of changes in restricted cash within the statement of cash flows. The new standard was issued to eliminate a current diversity in practice for the accounting treatment of restricted cash. Under the new guidance, reporting entities will be required to explain the changes in the total of restricted and unrestricted cash and cash equivalents when reconciling the beginning and ending balances on the statement of cash flows. Prior to the authoritative guidance, changes in restricted cash were presented as either cash flows from operating, investing, or financing activities within the statement of cash flows, as appropriate based on the nature of the restriction. Also under the new standard, reporting entities will be required to provide a reconciliation from the balance sheet to the statement of cash flows and disclose the nature of the restrictions of cash. This authoritative guidance will become effective January 1, 2018. Upon the effective date, MGE Energy and MGE will change the presentation of restricted cash to reflect this change in accounting guidance. MGE Energy and MGE will also retrospectively apply the guidance to all prior periods presented. As of September 30, 2017, and December 31, 2016, MGE Energy and MGE had $4.5 million and $5.1 million, respectively, of restricted cash classified within other current assets on the consolidated balance sheets.

Pension and Other Postretirement Benefits.

In March 2017, the FASB issued authoritative guidance within the Compensation – Retirement Benefits topic that provides guidance on the presentation of net periodic pension cost and net periodic postretirement benefit cost (together, net benefit cost). This authoritative guidance will become effective January 1, 2018. Under the new guidance, the service cost component of net benefit cost is required to be recorded in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside of income from operations. A practical expedient within the standard permits an employer to use the amounts disclosed in its pension and other postretirement benefit plan footnote for prior comparative periods as the estimation basis for applying the retrospective presentation requirements. MGE Energy and MGE have elected to apply the practical expedient. Operating income will decrease and other income will increase $6.6 million and $5.0 million for the years ended December 31, 2016 and 2015, respectively. The standard also only allows the service cost component to be eligible for capitalization prospectively from the effective date of the pronouncement (whereas under current GAAP, all components of net benefit cost are eligible for capitalization). MGE Energy and MGE are currently evaluating the impact of how the change in components of net benefit cost eligible for capitalization will affect our financial statements.

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 ATC Holdco, 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 149,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and distributes natural gas to approximately 154,000 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 MGE Energy's nonregulated operations are also consolidated into MGE's consolidated financial position and results of operations under applicable accounting standards.

Executive 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. MGE continues to examine and pursue opportunities to reduce the proportion that coal generation represents in its generation mix, including the announced reduction in its ownership of Columbia. MGE will continue to focus on growing earnings while controlling operating and fuel costs. MGE maintains 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,

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, including natural gas 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, and

Other factors listed in "Item 1A. Risk Factors" in our 2016 Annual Report on Form 10-K.

For the three months ended September 30, 2017, MGE Energy's earnings were $26.6 million or $0.77 per share compared to $27.9 million or $0.80 per share for the same period in the prior year. MGE's earnings for the three months ended September 30, 2017, were $19.9 million compared to $22.0 million for the same period in the prior year.

For the nine months ended September 30, 2017, MGE Energy's earnings were $61.5 million or $1.77 per share compared to $61.1 million or $1.76 per share for the same period in the prior year. MGE's earnings for the nine months ended September 30, 2017, were $41.5 million compared to $43.1 million for the same period in the prior year.

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


		Three Months Ended				Nine Months Ended
(In thousands)		September 30,				September 30,
Business Segment:		2017		2016		2017		2016

Net Income	$	26,629	$	27,880	$	61,472	$	61,058

Our net income during the three and nine months ended September 30, 2017, compared to the same period in the prior year primarily reflects the effects of the following factors:

Electric Utility

For the three months ended, electric net income decreased primarily resulting from cooler weather. The average temperature in August 2017 was 67 degrees compared to 73 in August 2016. For the nine months ended, electric net income increased primarily related to efforts to manage the level of operating and maintenance costs.

Transmission Investments

Transmission investment income reflects our share of ATC's earnings and a favorable comparison to 2016, which included an expense reflecting ATC's establishment of a reserve covering its estimate of its refund liability associated with the return on equity complaint filed with FERC. See "Other Matters" below for additional information concerning ATC.

During the first nine months ended of 2017, the following events occurred:

2017 Rate Case Order: On December 15, 2016, the PSCW authorized MGE, effective January 1, 2017, to decrease 2017 rates for retail electric customers by 0.8% or $3.3 million on an annual basis and to increase rates for retail gas customers by 1.9% or $3.1 million on an annual basis. The decrease in retail electric rates reflects declining fuel and purchased power costs. The increase in retail gas rates covers costs associated with MGE's natural gas system infrastructure improvements. The authorized return on common stock equity for 2017 is 9.8% based on a capital structure consisting of 57.2% common equity. The PSCW also approved MGE's request to extend the current accounting treatment for transmission related costs through 2018.

Deferred Fuel Costs: As of September 30, 2017, MGE has deferred $3.3 million of 2017 fuel savings. These costs will be subject to the PSCW's annual review of 2017 fuel costs, expected to be completed in 2018.

Debt Issuance: MGE issued $40 million of long-term unsecured debt in January 2017. The debt carries an interest rate of 3.76% per annum over its 35-year term. The proceeds of this debt financing were used to refinance $30 million of medium-term notes, which matured in January 2017, and assist with the financing of additional capital expenditures. The covenants of this debt are substantially consistent with MGE's existing unsecured long-term debt.

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

2016 Annual Fuel Proceeding: In July 2017, the PSCW issued a final order in the fuel rules proceedings requiring MGE to refund $6.0 million of additional fuel savings realized during 2015 and 2016 to its retail electric customers over a one-month period in October 2017.

ATC Return on Equity: Several parties have filed complaints with the FERC seeking to reduce the ROE used by MISO transmission owners, including ATC. Any change to ATC's ROE could result in lower equity earnings and distributions from ATC in the future. We derived approximately 7.2% and 5.8% of our net income for the nine months ended September 30, 2017 and 2016, respectively, from our investment in ATC. See "Other Matters" below for additional information concerning ATC.

Environmental Initiatives: There are proposed legislative 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. At present, it is unclear how the changes in the Presidential and EPA administrations may affect existing, pending or new legislative or rulemaking proposals or regulatory initiatives. Such legislation and rulemaking could significantly affect the costs of owning and operating fossil-fueled generating plants, such as Columbia and the Elm Road Units, from which we derive approximately 43% of our electric generating capacity as of September 30, 2017. 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, which may lag the incurrence of those costs.

EPA's Clean Power Plan: In October 2015, the EPA finalized its Clean Power Plan (CPP) rule with an effective date of December 2015, setting guidelines and approval criteria for states to use in developing plans to control GHG emissions from existing fossil fuel-fired electric generating units (EGUs) and systems. Implementation of the rule is expected to have a direct impact on existing coal and natural gas fired generating units, including possible changes in dispatch and additional operating costs. In October 2017, the EPA published a proposed rule announcing the EPA's intention to repeal the CPP and has sought public comment on whether to replace the rule, and if so how. Given the pending legal proceedings, and the EPA's proposal, the nature and timing of any final requirements to control GHG emissions from existing fossil fuel-fired EGUs is subject to uncertainty. If a rule is implemented substantially in its present form, it is expected to have a material impact on MGE. MGE will continue to monitor developments with this proposed rule.

Future Generation: During the first quarter of 2016, MGE entered into an agreement with WPL under which MGE may acquire up to 50 MW of capacity in a gas-fired generating plant to be constructed by WPL at its Riverside Energy Center in Beloit, Wisconsin, during the five-year period following the in-service date of the plant. The plant is expected to be completed by early 2020. MGE and WPL have negotiated an amendment to the existing Columbia joint operating agreement, effective January 1, 2017, under which MGE will reduce its obligation to pay certain capital expenditures (other than SCR-related expenditures) at Columbia prior to the expected in-service date of the Riverside gas-fired generating plant in exchange for a proportional reduction in MGE's ownership in Columbia. On January 1 of each year, beginning in 2017 and ending June 1, 2020, the ownership percentage will be adjusted, through a partial sale, based on the amount of capital expenditures foregone. During three and nine months ended September 30, 2017, MGE accrued $1.6 million and $6.7 million of 2017 capital expenditures that MGE has forgone as part of the ownership transfer agreement with WPL. During 2016, MGE accrued $14.8 million of 2016 capital expenditures forgone. As of September 30, 2017, and December 31, 2016, MGE classified $6.7 million and $14.8 million, respectively, of Columbia assets as held-for-sale on the consolidated balance sheets. In January 2017, MGE reduced its ownership interest in Columbia from 22.0% to 20.4% through the partial sale of plant assets to WPL. By June 2020, MGE's ownership in Columbia is forecasted to be approximately 19%.

Saratoga Wind Farm: In April 2017, MGE filed an application with the PSCW to seek approval to construct, own and operate a 66MW wind farm, consisting of 33 turbines, located near Saratoga, Iowa. If approved by the PSCW, construction of the project is expected to begin in early 2018, with an estimated capital cost of $107 million.

Forward Wind: In October 2017, MGE, along with two other utilities, entered into an agreement to purchase the Forward Wind Energy Center, which consists of 86 wind turbines located in Wisconsin with a total capacity of 129 MWs. The aggregate purchase price is approximately $174 million of which MGE's proportionate share is 12.8%, or approximately $23 million. MGE currently purchases 12.8% of the facility's energy output under a purchase power agreement. The transaction is subject to PSCW and FERC approvals and is expected to close in the spring of 2018.

Debt Issuance: In October 2017, MGE issued $30 million of long-term unsecured debt to cover capital expenditures and other corporate obligations. The debt carries an interest rate of 3.11% per annum, over its 10-year term. The covenants of this debt are substantially consistent with MGE's existing unsecured long-term debt.

The following discussion is based on the business segments as discussed in Footnote 13 of the Notes to Consolidated Financial Statements in this Report.

Electric operating revenues increased $1.7 million or 1.4% for the three months ended September 30, 2017, compared to the same period in 2016, due to the following:


(In millions)
Deferral of fuel savings/fuel credit	$	9.6
Adjustments to revenues		0.6
Volume		(5.9)
Sales to the market		(1.1)
Other		(0.8)
Rate changes		(0.7)
Total	$	1.7

Deferral of fuel savings/fuel credit. During the three months ended September 30, 2016, customers received a fuel credit on their bill related to accumulated fuel savings of $17.8 million, which decreased electric revenues in the prior year. In January 2016, the PSCW lowered MGE's 2016 fuel rules monitored costs, which were deferred in revenue in the prior period, as a result of continued lower projected fuel costs in 2016.

Adjustments to revenue. MGE leases electric generating capacity from MGE Power Elm Road. MGE collects in rates the lease payments associated with the electric generating capacity as authorized by the PSCW. Any differential between estimated lease payments collected in rates and actual lease payments paid to MGE Power Elm Road are included in adjustments to revenues.

Volume. During the three months ended September 30, 2017, there was a 20.3% decrease in industrial retail sales volumes compared to the same period in the prior year as a result of a large industrial customer relocating its operations out of state. During the three months ended September 30, 2017, there was a 12.9% decrease in residential sales volumes compared to the same period in the prior year driven by decreased customer demand due, at least in part, to less favorable weather conditions, as evidenced by the lower number of cooling degree days.

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 are needed for its own system demand. The excess electricity is then sold to others in the market. For the three months ended September 30, 2017, market volumes decreased compared to the same period in the prior year, reflecting decreased opportunities for sales and those sales were made at lower market prices. The revenue generated from these sales is included in fuel rules monitored costs. See fuel rules discussion in Footnote 8.b. of the Notes to the Consolidated Financial Statements.

Rate Changes. In December 2016, the PSCW authorized MGE to decrease 2017 rates for retail electric customers by 0.8% or $3.3 million on an annual basis.

Rates charged to retail customers for the three months ended September 30, 2017, were 2.4% or $0.7 million lower than those charged during the same period in the prior year.

Electric fuel and purchased power

Electric fuel and purchased power costs reflect an increase in the volume of purchased power offset by a decrease in internal generation volumes when compared to the prior period. Adjustments related to the regulatory recovery for fuel costs, known as fuel rules, increased purchased power expense. These items are explained below.

Fuel for electric generation

The expense for fuel for internal electric generation decreased $4.7 million during the three months ended September 30, 2017, compared to the same period in the prior year, due to the following:


(In millions)
Decrease in volume	$	(3.2)
Decrease in per-unit cost		(1.5)
Total	$	(4.7)

This decrease in expense reflects a 15.8% decrease in internal generation volume delivered to the system primarily as a result of decreased generation at WCCF based on market prices and an 8.4% decrease in per-unit cost of internal electric generation.

Purchased power

Purchased power expense increased $6.8 million during the three months ended September 30, 2017, compared to the same period in the prior year, due to the following:


(In millions)
Change in fuel rule adjustments, net of recoveries	$	5.0
Increase in volume		2.2
Decrease in per-unit cost		(0.4)
Total	$	6.8

Under fuel rules, MGE is required to defer electric fuel-related costs that fall outside a 2% cost tolerance band around the amount used in the most recent rate proceeding. Any fuel rules adjustments are reflected in purchased power expense, with potential refunds associated with fuel savings increasing that expense and potential recovery of excess fuel costs decreasing that expense.

The increase in expense (before fuel rules adjustments) reflects a 17.4% increase in the volume of power purchased from third parties partially offset by a 2.5% decrease in the per-unit cost of purchased power.

Electric operating and maintenance expenses

For the three months ended September 30, 2017, electric operating and maintenance expenses increased $0.6 million, compared to the same period in the prior year. The following contributed to the net change:


(In millions)
Increased transmission costs	$	1.3
Increased customer accounts costs		0.5
Decreased production expenses		(0.5)
Decreased distribution expenses		(0.5)
Decreased administrative and general costs		(0.2)
Total	$	0.6

For the three months ended September 30, 2017, increased transmission costs are primarily due to an increase in transmission reliability enhancements.

Electric depreciation expense

Electric depreciation expense increased $1.9 million for the three months ended September 30, 2017, compared to the same period in the prior year as a result of new depreciation rates for Columbia, as approved by the PSCW.

Other electric income

Other electric income increased $1.3 million for the three months ended September 30, 2017, compared to the same period in the prior year, primarily due to the gain on sale of property assets.

Gas Utility Operations - MGE Energy and MGE

Gas deliveries and revenues

The following table compares MGE's gas revenues and gas therms delivered by customer class during each of the periods indicated:


		Revenues				Therms Delivered
(In thousands, except HDD and average rate per therm of retail customer)		Three Months Ended September 30,				Three Months Ended September 30,

Heating degree days (normal 158)						138	49	181.6 %
Average rate per therm of
retail customer	$	1.208	$	1.181	2.3 %

Gas revenues increased $1.2 million or 6.9% for the three months ended September 30, 2017, compared to the same period in 2016. These changes are related to the following factors:


(In millions)
Rate/PGA changes	$	0.9
Volume		0.3
Total	$	1.2

Rate/PGA changes. In December 2016, the PSCW authorized MGE to increase 2017 rates for retail gas customers by 1.9% or $3.1 million on an annual basis.

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. Changes in PGA recoveries affect revenues but do not change net income.

The average retail rate per therm for the three months ended September 30, 2017, increased 2.3% compared to the same period in 2016, reflecting a $0.5 million increase in natural gas commodity costs (recovered through the PGA) and an increase in fixed rate charges.

Volume. For the three months ended September 30, 2017, retail gas deliveries increased 5.2% compared to the same period in the prior year.

Cost of gas sold

For the three months ended September 30, 2017, cost of gas sold increased $0.8 million compared to the same period in the prior year. The cost per therm of natural gas increased 10.5%, which resulted in $0.5 million of increased expense. The volume of gas purchased increased 6.9%, which resulted in $0.3 million of increased expense.

Gas operating and maintenance expenses

Gas operating and maintenance expenses increased by $0.7 million for the three months ended September 30, 2017, compared to the same period in 2016. The following contributed to the net change:


(In millions)
Increased customer accounts costs	$	0.7
Increased customer service costs		0.2
Increased other costs		0.2
Decreased administrative and general costs		(0.4)
Total	$	0.7

For the three months ended September 30, 2017, increased customer accounts costs are primarily related to technology improvements.

Nonregulated Energy Operations - MGE Energy and MGE

The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power Elm Road (the Elm Road Units) and MGE Power West Campus (WCCF), which have been formed to own and lease electric generating capacity to assist MGE. For the three months ended September 30, 2017 and 2016, net income at the nonregulated energy operations segment was $4.8 million and $4.7 million, respectively.

Transmission Investment Operations - MGE Energy and MGE

Transmission investment other income

For the three months ended September 30, 2017 and 2016, other income at the transmission investment segment was $2.3 million and $2.0 million, respectively. The transmission investment segment holds our interest in ATC and ATC Holdco, and its income reflects our equity in the earnings of the investments. ATC Holdco was formed in December 2016. In the near term, it is expected that ATC Holdco will be pursuing transmission development opportunities that typically have long development and investment lead times before becoming operational. See Footnote 3 of the Notes to Consolidated Financial Statements in this Report and "Other Matters" below for additional information concerning ATC and summarized financial information regarding ATC.

Consolidated Income Taxes - MGE Energy and MGE

Noncontrolling Interest, Net of Tax - MGE

The noncontrolling interest, net of tax, reflects the accounting required for MGE Energy's interest in MGE Power Elm Road (the Elm Road Units) and MGE Power West Campus (WCCF). MGE Energy owns 100% of MGE Power Elm Road and MGE Power West Campus; however, due to the contractual agreements for these projects with MGE, the entities are considered VIEs with respect to MGE and their results are consolidated with those of MGE, the primary beneficiary of the VIEs. Also included in noncontrolling interest, net of tax, for the three months ended September 30, 2016, was MGE Energy's interest in MGE Transco, which holds our investment in ATC.

The following table shows MGE Energy's noncontrolling interest, net of tax, reflected on MGE's consolidated statement of income:


		Three Months Ended
		September 30,
(In millions)		2017		2016
MGE Power Elm Road	$	3.6	$	3.7
MGE Power West Campus		1.8		1.8
MGE Transco^(a)		-		0.2

(a)

MGE Transco holds an ownership interest in ATC. In July 2016, MGE's ownership interest in MGE Transco declined below a majority, resulting in MGE Energy's investment in MGE Transco being deconsolidated from MGE's consolidated financial statements. In December 2016, MGE's ownership interest in MGE Transco was transferred to MGE Energy. See Footnote 3 of the Notes to Consolidated Financial Statements in this Report for additional information.

Other Commitments - MGE Energy

In May 2017, MGE Energy entered a subscription agreement to invest in a nonpublic venture capital fund. From time to time, this entity will require capital infusions from its investors. MGE Energy has committed to contribute $5 million in capital for such infusions. The timing of these infusions is dependent on the needs of the investee and is therefore uncertain at this time.

Long-term Debt - MGE Energy and MGE

MGE issued $40 million of long-term unsecured debt in January 2017. The proceeds of this debt financing were used to refinance $30 million of medium-term notes, which matured in January 2017, and assist with the financing of additional capital expenditures. In October 2017, MGE also issued an additional $30 million of long-term unsecured debt to cover capital expenditures and other corporate obligations. See Footnote 2 of the Notes to Consolidated Financial Statements in this Report for further discussion of these debt issuances.

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 nine months ended September 30, 2017, was $99.0 million, a decrease of $30.2 million when compared to the same period in the prior year, primarily reflecting changes in working capital items between the periods.

MGE Energy's net income increased $0.4 million for the nine months ended September 30, 2017, when compared to the same period in the prior year.

In 2016, MGE received a $10.0 million refund from the IRS for the 2015 tax year. Excluding the 2016 refund, MGE Energy's federal and state taxes paid increased $10.2 million during the nine months ended September 30, 2017, when compared to the same period in the prior year.

Working capital accounts (excluding prepaid and accrued taxes) resulted in $13.9 million in cash used for operating activities for the nine months ended September 30, 2017, primarily due to decreased accounts payable and increased inventories, partially offset by decreased unbilled revenues, decreased other current assets, and increased other current liabilities.

Working capital accounts (excluding prepaid and accrued taxes) resulted in $7.6 million in cash provided by operating activities for the nine months ended September 30, 2016, primarily due to decreased inventories, decreased unbilled revenues, increased accounts payable, and increased other current liabilities, partially offset by increased receivables. The increase in current liabilities includes a fuel credit, that was approved in August 2015, of $6.3 million that customers received on their bill from January through September 2016 and a one-time fuel credit, approved in July 2016, of $15.5 million that customers received on their bill in September 2016.

A decrease in pension contribution resulted in an additional $3.4 million in cash provided by operating activities for the nine months ended September 30, 2017, when compared to the same period in the prior year. Pension contributions reflect amounts required by law and discretionary amounts.

Cash provided by operating activities for the nine months ended September 30, 2017, was $94.4 million, a decrease of $34.6 million when compared to the same period in the prior year, primarily reflecting changes in working capital items between the periods.

Net income decreased $3.3 million for the nine months ended September 30, 2017, when compared to the same period in the prior year.

Working capital accounts (excluding prepaid and accrued taxes) resulted in $13.6 million in cash used for operating activities for the nine months ended September 30, 2017, primarily due to decreased accounts payable and increased inventories, partially offset by decreased unbilled revenues, decreased other current assets, and increased other current liabilities.

Working capital accounts (excluding prepaid and accrued taxes) resulted in $7.7 million in cash provided by operating activities for the nine months ended September 30, 2016, primarily due to decreased inventories, decreased unbilled revenues, increased accounts payable, and increased other current liabilities, partially offset by increased receivables. The increase in current liabilities includes a fuel credit, that was approved in August 2015, of $6.3 million that customers received on their bill from January through September 2016 and a one-time fuel credit, approved in July 2016, of $15.5 million that customers received on their bill in September 2016.

Common shareholders' equity	65.3 %	65.2 %
Long-term debt^(a)	34.1 %	34.8 %
Short-term debt	0.6 %	-%

(a)

Includes the current portion of long-term debt.

MGE Energy's and MGE's Capital Requirements

MGE Energy's and MGE's liquidity are primarily affected by their capital requirements. During the nine months ended September 30, 2017, capital expenditures for MGE Energy and MGE totaled $66.3 million, which included $63.9 million of capital expenditures for utility operations.

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 borrowings are 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 nine months ended September 30, 2017. Further discussion of environmental matters is included in MGE Energy's and MGE's 2016 Annual Report on Form 10-K and Footnote 7.a. of Notes to Consolidated Financial Statements in this Report.

EPA's Clean Power Plan

In October 2015, the EPA finalized its Clean Power Plan (CPP) rule with an effective date of December 2015, setting guidelines and approval criteria for states to use in developing plans to control GHG emissions from existing fossil fuel-fired electric generating units (EGUs) and systems. Implementation of the rule is expected to have a direct impact on existing coal and natural gas fired generating units, including possible changes in dispatch and additional operating costs. In October 2017, the EPA published a proposed rule announcing the EPA's intention to repeal the CPP and has sought public comment on whether to replace the rule, and if so how. Given the pending legal proceedings, and the EPA's proposal, the nature and timing of any final requirements to control GHG emissions from existing fossil fuel-fired EGUs is subject to uncertainty. If a rule is implemented substantially in its present form, it is expected to have a material impact on MGE. MGE will continue to monitor developments with this proposed rule.

Other Matters

ATC

In 2013, several parties filed a complaint with the FERC seeking to reduce the base return on equity (ROE) used by MISO transmission owners, including ATC, "due to changes in the capital markets." The complaint alleged that the MISO ROE should not exceed 9.15%, the equity components of hypothetical capital structures should be restricted to 50%, and the relevant incentive ROE adders should be discontinued. At the time, MISO's base ROE was 12.38% and ATC's base ROE was 12.2%. In February 2015, a second complaint was filed for the period February 2015 through May 2015 with the FERC requesting a reduction in the base ROE used by MISO transmission owners, including ATC, to 8.67%, with a refund effective date retroactive to the filing date of the complaint. In June 2016, an administrative law judge issued an initial decision for the second complaint that would reduce the transmission owner's base ROE to 9.7%. The initial decision will be reviewed by FERC. It is anticipated FERC will issue an order on this issue in the beginning of 2018. On September 28, 2016, FERC issued an order on the first complaint, for the period November 2013 through February 2015, reducing the base ROE to 10.32%. This base ROE also became effective September 28, 2016, and will apply to future periods until FERC rules in the second complaint, at which time the base ROE ordered by FERC in the second complaint will prospectively become the authorized base ROE.

In January 2015, FERC accepted the transmission owner's request for a 50 basis-point incentive ROE adder for participating in MISO. The adder became effective January 6, 2015.

Any change to ATC's ROE could result in lower equity earnings and distributions from ATC in the future. Our share of ATC's earnings reflects a pre-tax expense of $0.7 million for the three months ended September 30, 2016, and a pre-tax expense of $0.2 million and $1.8 million for the nine months ended September 30, 2017 and 2016, respectively, recorded by ATC for this matter representing its estimate of its refund liability. There was not a pre-tax expense for the three months ended September 30, 2017. We derived approximately 7.2% and 5.8% of our net income for the nine months ended September 30, 2017 and 2016, respectively, from our investment in ATC.

Adoption of Accounting Principles and Recently Issued Accounting Pronouncements

See Footnote 12 of Notes to Consolidated Financial Statements in this Report for discussion of new accounting pronouncements.

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'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 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. 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 in the following year and is then reflected 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 costs fall outside the lower end of the range and is required to defer costs, less any excess revenues, if the actual electric fuel costs exceed 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 2017, fuel and purchased power costs included in MGE's base fuel rates are $101.9 million. See Footnote 8.b. of the Notes to Consolidated Financial Statements in this Report for additional information.

MGE recovers the cost of natural gas in its gas utility 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 utility 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 September 30, 2017, the fair value of these instruments exceeded their cost basis by $0.9 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 sheets as a regulatory asset/liability.

MGE has also entered into a purchased power agreement that provides MGE with firm capacity and energy that began on June 1, 2012, and ends on May 31, 2022. The agreement also allows MGE an option to extend the contract after that base term. The agreement is considered 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 September 30, 2017, reflects a loss position of $43.1 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 September 30, 2017, 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 1,682 square miles in Wisconsin. Based on results for the year ended December 31, 2016, 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 third quarter of 2017, 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, 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 September 30, 2017, 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 September 30, 2017, 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 MGE Energy's 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.
