1. Nature of business

General

Atlantic Power owns and operates a diverse fleet of power generation assets in the United States and Canada. Our power generation projects sell electricity to utilities and other large commercial customers largely under long-term power purchase agreements ("PPAs"), which seek to minimize exposure to changes in commodity prices. As of March 31, 2015, our power generation projects in operation had an aggregate gross electric generation capacity of approximately 2,137 megawatts ("MW") in which our aggregate ownership interest is approximately 1,502 MW. Our current portfolio consists of interests in twenty-three operational power generation projects across nine states in the United States and two provinces in Canada. Eighteen of our projects are majority-owned subsidiaries. These totals exclude an aggregate of 521 MWs from our 100% ownership interest in Meadow Creek Project Company, LLC ("Meadow Creek"), our 99% ownership in Canadian Hills Wind, LLC ("Canadian Hills"), our 50% ownership interest in Rockland Wind Farm, LLC ("Rockland"), our 27.6% ownership interest in Idaho Wind Partners 1, LLC ("Idaho Wind") and our 12.5% ownership interest in Goshen Phase II, LLC ("Goshen") (collectively, the "Wind Projects"), for which we entered into an agreement to sell on March 31, 2015, and which are designated as assets held for sale and discontinued operations at March 31, 2015.

Atlantic Power is a corporation established under the laws of the Province of Ontario, Canada on June 18, 2004 and continued to the Province of British Columbia on July 8, 2005. Our shares trade on the Toronto Stock Exchange under the symbol "ATP" and on the New York Stock Exchange under the symbol "AT." Our registered office is located at 215-10451 Shellbridge Way, Richmond, British Columbia V6X 2W8 Canada and our headquarters is located at 3 Allied Drive, Suite 220, Dedham, Massachusetts 02026, USA. Our telephone number in Dedham is (617) 977-2400 and the address of our website is www.atlanticpower.com. Information contained on Atlantic Power's website or that can be accessed through its website is not incorporated into and does not constitute a part of this Quarterly Report on Form 10-Q. We have included our website address only as an inactive textual reference and do not intend it to be an active link to our website. We make available on our website, free of charge, our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission ("SEC"). Additionally, we make available on our website our Canadian securities filings, which are not incorporated by reference into our Exchange Act filings.

Basis of presentation

The interim consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared in accordance with the SEC regulations for interim financial information and with the instructions to Form 10-Q. The following notes should be read in conjunction with the accounting policies and other disclosures as set forth in the notes to our financial statements in our Annual Report on Form 10-K for the year ended December 31, 2014. Interim results are not necessarily indicative of results for the full year.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(in millions U.S. dollars, except per-share amounts)

(Unaudited)

1. Nature of business (Continued)

In our opinion, the accompanying unaudited interim consolidated financial statements present fairly our consolidated financial position as of March 31, 2015, the results of operations and comprehensive loss for the three months ended March 31, 2015 and 2014, and our cash flows for the three months ended March 31, 2015 and 2014. In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation have been included.

Use of estimates

The preparation of financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the year. Actual results could differ from those estimates. During the periods presented, we have made a number of estimates and valuation assumptions, including the fair values of acquired assets, the useful lives and recoverability of property, plant and equipment, valuation of goodwill, intangible assets and liabilities related to PPAs and fuel supply agreements, the recoverability of equity investments, the recoverability of deferred tax assets, tax provisions, the fair value of financial instruments and derivatives, pension obligations, asset retirement obligations, equity-based compensation and the allocation of taxable income and losses, tax credits and cash distributions using the hypothetical liquidation book value ("HLBV") method. In addition, estimates are used to test long-lived assets and goodwill for impairment and to determine the fair value of impaired assets. These estimates and valuation assumptions are based on present conditions and our planned course of action, as well as assumptions about future business and economic conditions. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates" in our Annual Report on Form 10-K for the year ended December 31, 2014. As better information becomes available or actual amounts are determinable, the recorded estimates are revised. Should the underlying valuation assumptions and estimates change, the recorded amounts could change by a material amount.

Revision to the presentation of preferred shares issued by a subsidiary company

The classification of preferred shares issued by a subsidiary company has been revised from total Atlantic Power Corporation shareholder's equity on the Consolidated Balance Sheets at March 31, 2015 and December 31, 2014 to a separate line item in the non-controlling interests section of equity. The revision does not impact total equity in either period presented. The revision was appropriate in order to properly present the preferred shares issued by a subsidiary company in the consolidated balance sheet. The revision is not considered material to any previously issued financial statements.

Recently issued accounting standards

Adopted

In April 2014, the Financial Accounting Standards Board ("FASB") issued changes to reporting discontinued operations and disclosures of disposals of components of an entity. These changes require a disposal of a component to meet a higher threshold in order to be reported as a discontinued

Table of Contents

ATLANTIC POWER CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(in millions U.S. dollars, except per-share amounts)

(Unaudited)

1. Nature of business (Continued)

operation in an entity's financial statements. The threshold is defined as a strategic shift that has, or will have, a major effect on an entity's operations and financial results such as a disposal of a major geographical area or a major line of business. Additionally, the following two criteria have been removed from consideration of whether a component meets the requirements for discontinued operations presentation: (i) the operations and cash flows of a disposal component have been or will be eliminated from the ongoing operations of an entity as a result of the disposal transaction, and (ii) an entity will not have any significant continuing involvement in the operations of the disposal component after the disposal transaction. Furthermore, equity method investments now may qualify for discontinued operations presentation. These changes also require expanded disclosures for all disposals of components of an entity, whether or not the threshold for reporting as a discontinued operation is met, related to profit or loss information and/or asset and liability information of the component. These changes became effective on January 1, 2015 and were implemented when designating the Wind Projects as assets held for sale and discontinued operations on March 31, 2015. See Note 3, Assets held for sale and discontinued operations .

Issued

In February 2015, the FASB issued changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities. These changes (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with variable interest entities, particularly those that have fee arrangements and related party relationships, and (iv) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. These changes become effective for us on January 1, 2016. We are currently evaluating the potential impact of these changes on the consolidated financial statements.

In January 2015, the FASB issued changes to the presentation of extraordinary items. Such items are defined as transactions or events that are both unusual in nature and infrequent in occurrence, and, currently, are required to be presented separately in an entity's income statement, net of income tax, after income from continuing operations. The changes eliminate the concept of an extraordinary item and, therefore, the presentation of such items will no longer be required. Notwithstanding this change, an entity will still be required to present and disclose a transaction or event that is both unusual in nature and infrequent in occurrence in the notes to the financial statements. These changes become effective for us on January 1, 2016. We have determined that the adoption of these changes will not have an impact on the consolidated financial statements.

In August 2014, the FASB issued changes to the disclosure of uncertainties about an entity's ability to continue as a going concern. Under generally accepted accounting principles in the United States ("GAAP"), continuation of a reporting entity as a going concern is presumed as the basis for preparing financial statements unless and until the entity's liquidation becomes imminent. Even if an entity's liquidation is not imminent, there may be conditions or events that raise substantial doubt about the

Table of Contents

ATLANTIC POWER CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(in millions U.S. dollars, except per-share amounts)

(Unaudited)

1. Nature of business (Continued)

entity's ability to continue as a going concern. Because there is no guidance in GAAP about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern or to provide related note disclosures, there is diversity in practice whether, when, and how an entity discloses the relevant conditions and events in its financial statements. As a result, these changes require an entity's management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that financial statements are issued. Substantial doubt is defined as an indication that it is probable that an entity will be unable to meet its obligations as they become due within one year after the date that financial statements are issued. If management has concluded that substantial doubt exists, then the following disclosures should be made in the financial statements: (i) principal conditions or events that raised the substantial doubt, (ii) management's evaluation of the significance of those conditions or events in relation to the entity's ability to meet its obligations, (iii) management's plans that alleviated the initial substantial doubt or, if substantial doubt was not alleviated, management's plans that are intended to at least mitigate the conditions or events that raise substantial doubt, and (iv) if the latter in (iii) is disclosed, an explicit statement that there is substantial doubt about the entity's ability to continue as a going concern. These changes become effective for us for financial statements issued after December 15, 2016. We are currently evaluating the potential impact of these changes on the consolidated financial statements. Subsequent to adoption, this guidance will need to be applied by management at the end of each annual period and interim period therein to determine what, if any, impact there will be on the consolidated financial statements in a given reporting period.

In May 2014, the FASB issued changes to the recognition of revenue from contracts with customers. These changes created a comprehensive framework for all entities in all industries to apply in the determination of when to recognize revenue, and, therefore, supersede virtually all existing revenue recognition requirements and guidance. This framework is expected to result in less complex guidance in application while providing a consistent and comparable methodology for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract(s), (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract(s), and (v) recognize revenue when, or as, the entity satisfies a performance obligation. These changes become effective on January 1, 2017. We are currently evaluating the potential impact of these changes on the consolidated financial statements.

adjustments. Terraform will, subject to the terms and conditions in the Purchase Agreement, purchase from APT 100% of its direct membership interests in a holding company formed to facilitate the sale, thereby acquiring our indirect interests in our portfolio of wind projects consisting of five operating wind projects in Idaho and Oklahoma and representing 521 MW net ownership: Goshen (12.5% economic interest), Idaho Wind (27.6% economic interest), Meadow Creek (100% economic interest); Rockland Wind Farm (50% economic interest, but consolidated on a 100% basis); and Canadian Hills (99% economic interest).

On January 1, 2015, we adopted the FASB's issued changes to reporting discontinued operations and determined that the sale of the Wind Projects meets the threshold to be reported as discontinued operations in our consolidated financial statements. Our determination was based on the impact the sale will have on our operations and financial results and because the Wind Projects make up the entirety of our Wind reportable Segment. The Wind Projects were designated as assets held for sale and discontinued operations on March 31, 2015, the date we established a firm commitment to a plan to sell the wind assets. We stopped depreciating the property, plant and equipment of the Wind Projects on the designation date. We did not adjust the carrying value on the designation date because we expect to record a gain on sale when the transaction closes. The consolidated balance sheet as of December 31, 2014 and the consolidated statement of operations for the three months ended March 31, 2014 have been reclassified for these changes.

Greeley

In March 2014, we closed a transaction with Initium Power Partners, LLC. ("Initium"), whereby Initium agreed to purchase all of the issued and outstanding membership interests in Greeley for approximately $1.0 million. We recorded a $2.1 million non-cash gain on the sale resulting from the write-off of asset retirement obligations in the consolidated statement of operations as of March 31, 2014. Greeley is accounted for as a component of discontinued operations in the consolidated statements of operations for the three months ended March 31, 2014.

payment and charges for unamortized debt discount and fee expenses and premiums as part of the overall purchase price in respect of the repurchases of the 9.0% Notes in March 2014, which were reflected as interest expense in our 2014 first quarter results, through March 31, 2015, we did not satisfy the fixed charge coverage ratio test included in the restricted payments covenant of the indenture governing the 9.0% Notes. The fixed charge coverage ratio must be at least 1.75 to 1.00 and is measured on a rolling four quarter basis, including after giving effect to certain pro forma adjustments.

As of March 31, 2015, we are again in compliance with the fixed charge ratio test. During the period we were not in compliance, March 31, 2014 through March 31, 2015, dividend payments, in the aggregate, could not exceed the covenant's "basket" provision of the greater of $50 million and 2% of consolidated net assets (approximately $46.7 million at March 31, 2015) until we satisfied the fixed charge coverage ratio test. Through March 31, 2015, we declared cumulative dividends totaling approximately $35.4 million that were subject to the basket provision. As long as we remain in compliance with the ratio test, we are not subject to the basket provision. However, the basket does not reset if we were to fall out of compliance at any point in the future. Dividends to shareholders are paid, if and when declared by, and subject to the discretion of, the board of directors.

Non-Recourse Debt

Project-level debt of our consolidated projects is secured by the respective project and its contracts with no other recourse to us. Project-level debt generally amortizes during the term of the respective revenue generating contracts of the projects. The loans have certain financial covenants that must be met in order to distribute available cash. At March 31, 2015, all of our projects with the exception of Piedmont were in compliance with the covenants contained in project-level debt. We do not expect our Piedmont project to meet its debt service coverage ratio covenants limiting the project's ability to make distributions to us before 2017 at the earliest, due to continued operational issues that have resulted in higher forecasted maintenance and fuel expenses than initially expected.

6. Convertible debentures (Continued)

During the fourth quarter of 2014, we announced a Normal Course Issuer Bid ("NCIB") for our convertible debentures. Under the NCIB, we entered into a pre-defined automatic securities purchase plan with our broker in order to facilitate purchases of our convertible debentures. The NCIB commenced on November 11, 2014 and will expire on November 10, 2015 or such earlier date as we complete our purchases pursuant to the NCIB. The actual amount of convertible debentures that may be purchased under the NCIB cannot exceed approximately $31 million and is further limited based on the outstanding principal of the individual outstanding tranches. As of December 31, 2014, we had repurchased and cancelled $3.1 million of convertible debentures and recorded a gain of $0.7 million in the consolidated statement of operations related to these transactions. During the first quarter of 2015, we repurchased and cancelled $7.0 million aggregate principal amount of convertible debentures at a cost of $5.7 million and recorded a gain of $1.3 million in the consolidated statement of operations for the three months ended March 31, 2015. In April 2015, we repurchased and cancelled an additional $10.3 million aggregate principal amount of convertible debentures at a cost of $8.6 million. The associated gain will be recorded in the statement of operations for the three and six months ended June 30, 2015.

7. Fair value of financial instruments

The following represents the recurring measurements of fair value hierarchy of our financial assets and liabilities that were recognized at fair value as of March 31, 2015 and December 31, 2014. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

Liabilities:

Total	$	—	$	83.6	$	—	$	83.6

The fair values of our derivative instruments are based upon trades in liquid markets. Valuation model inputs can generally be verified and valuation techniques do not involve significant judgment. The fair values of such financial instruments are classified within Level 2 of the fair value hierarchy. We use our best estimates to determine the fair value of commodity and derivative contracts we hold. These estimates consider various factors including closing exchange prices, time value, volatility factors and credit exposure. The fair value of each contract is discounted using a risk free interest rate.

We also adjust the fair value of financial assets and liabilities to reflect credit risk, which is calculated based on our credit rating and the credit rating of our counterparties. As of March 31, 2015, the credit valuation adjustments resulted in a $5.5 million net increase in fair value, which consists of a $0.5 million pre-tax gain in other comprehensive income and a $5.0 million gain in change in fair value of derivative instruments. As of December 31, 2014, the credit valuation adjustments resulted in an $8.3 million net increase in fair value, which consists of a $0.7 million pre-tax gain in other comprehensive income and a $7.6 million gain in change in fair value of derivative instruments.

The carrying amounts for cash and cash equivalents and restricted cash approximate fair value due to their short-term nature.

8. Accounting for derivative instruments and hedging activities

We recognize all derivative instruments on the balance sheet as either assets or liabilities and measure them at fair value in each reporting period. We have one contract designated as a cash flow hedge, and we defer the effective portion of the change in fair value of the derivatives in accumulated other comprehensive income (loss), until the hedged transactions occur and are recognized in earnings (loss). The ineffective portion of a cash flow hedge is immediately recognized in earnings (loss). For our other derivatives that are not designated as cash flow hedges, the changes in the fair value are immediately recognized in earnings (loss). These guidelines apply to our natural gas swaps, interest rate swaps, and foreign exchange contracts.

Gas purchase agreements

Gas purchase agreements to purchase gas forward at our North Bay, Kapuskasing and Nipigon projects do not qualify for the normal purchase normal sales ("NPNS") exemption and are accounted for as derivative financial instruments. The gas purchase agreements at North Bay and Kapuskasing satisfy all of the forecasted fuel requirements for these projects through their expiration on December 31, 2016. The gas purchase agreement for Nipigon satisfies the majority of forecasted fuel requirements through December 31, 2022. These derivative financial instruments are recorded in the consolidated balance sheets at fair value and the changes in their fair market value are recorded in the consolidated statements of operations.

In June 2014, Atlantic Power Limited Partnership (the "Partnership") entered into contracts for the purchase of 2.9 million Gigajoules ("Gj") of future natural gas purchases beginning on November 1, 2014 and expiring on December 31, 2017 for our projects in Ontario. These contracts effectively fix the price of approximately 98% of our expected uncontracted gas requirements for 2015 and 32% and 30% of our expected uncontracted gas requirements for 2016 and 2017, respectively. These contracts are accounted for as derivative financial instruments and are recorded in the consolidated balance sheet at fair value at March 31, 2015. Changes in the fair market value of these contracts are recorded in the consolidated statement of operations.

Natural gas swaps

Our strategy to mitigate future exposure to changes in natural gas prices at our projects consists of periodically entering into financial swaps that effectively fix the price of natural gas expected to be purchased at these projects. These natural gas swaps are derivative financial instruments and are recorded in the consolidated balance sheets at fair value and the changes in their fair market value are recorded in the consolidated statements of operations.

We have entered into various natural gas swaps to effectively fix the price of 6.3 million Mmbtu of future natural gas purchases at Orlando, which is approximately 100% of our share of the expected on-peak natural gas purchases at the project through 2016 or approximately 96% and 65% of our share of the expected base load natural gas purchases for 2015 and 2016, respectively. These contracts are accounted for as derivative financial instruments and are recorded in the consolidated balance sheet at fair value at March 31, 2015. Changes in the fair market value of these contracts are recorded in the consolidated statement of operations.

The operating margin at our 50% owned Orlando project is exposed to changes in natural gas prices following the expiration of its fuel contract at the end of 2013. We previously entered into natural gas swaps to effectively fix the price of 4.5 million Mmbtu of future natural gas purchases. On February 20, 2014, we paid $4.0 million to terminate a portion of these contracts in connection with the termination of our prior revolving credit facility. We recorded fuel expense related to the settlement of these contracts in the consolidated statement of operations for the three months ended March 31, 2014.

Interest rate swaps

On May 5, 2014, the Partnership entered into interest rate swap agreements to mitigate exposure to changes in the Adjusted Eurodollar Rate for $199.0 million notional amount ($172.4 million at March 31, 2015) of the $600 million aggregate principal amount of borrowings ($520.2 million of borrowings at March 31, 2015) under the Term Loan Facility. Borrowings under the $600 million Term Loan Facility bear interest at a rate equal to the Adjusted Eurodollar Rate plus an applicable margin of 3.75%. Based on the terms of the Credit Agreement, the Adjusted Eurodollar Rate cannot be less than 1.00% resulting in a minimum of a 4.75% all-in rate on the Term Loan Facility. As a result of entering into the swap agreements, the all-in rate for $199.0 million of the Term Loan Facility cannot be less than 4.91% if the Adjusted Eurodollar Rate is equal to or greater than 1.00%. If the Adjusted Eurodollar Rate is below 1.00%, we will pay interest at a rate equivalent to the minimum 4.75% all-in rate plus any difference between the actual Adjusted Eurodollar Rate and 1.16%. The interest rate swap agreements were effective June 30, 2014 and terminate on December 29, 2017. The interest rate swap agreements are not designated as hedges and changes in their fair market value will be recorded in the consolidated statements of operations.

The Piedmont project has interest rate swap agreements to economically fix its exposure to changes in interest rates related to its variable-rate debt. The interest rate swap agreement effectively converts the floating rate debt to a fixed interest rate of 1.7% plus an applicable margin ranging from 3.5% to 3.8% through February 29, 2016. From February 2016 until the maturity of the debt in November 2017, the fixed rate of the swap is 4.47% and the applicable margin is 4.0%, resulting in an all-in rate of 8.5%. The swap continues at the fixed rate of 4.47% from the maturity of the debt in November 2017 until November 2030. Prior to conversion of the Piedmont construction loan facility to a term loan, the notional amounts of the interest rate swap agreements matched the estimated outstanding principal balance of Piedmont's construction loan facility. The interest rate swaps were executed on October 21, 2010 and November 2, 2010 and expire on February 29, 2016 and November 30, 2030, respectively. As a result of the Piedmont term loan conversion on February 14, 2014, these swap agreements were amended to reduce the notional amounts to match the outstanding $68.5 million principal of the term loan. The interest rate swap agreements are not designated as hedges, and changes in their fair market value are recorded in the consolidated statements of operations.

The Cadillac project has an interest rate swap agreement that effectively fixes the interest rate at 6.0% through February 15, 2015, 6.1% from February 16, 2015 to February 15, 2019, 6.3% from February 16, 2019 to February 15, 2023, and 6.4% thereafter. The notional amount of the interest rate swap agreement matches the outstanding principal balance over the remaining life of Cadillac's debt. This swap agreement, which qualifies for and is designated as a cash flow hedge, is effective through June 2025 and the effective portion of the changes in the fair market value is recorded in accumulated other comprehensive loss.

Epsilon Power Partners, our wholly owned subsidiary, previously had an interest rate swap to economically fix the exposure to changes in interest rates related to the variable-rate non-recourse debt. The interest rate swap agreement effectively converted the floating rate debt to a fixed interest rate of

7.37% and had a maturity date of July 2019. The notional amount of the swap matched the outstanding principal balance over the remaining life of Epsilon Power Partners' debt. On February 20, 2014, we paid $2.6 million to terminate this contract in connection with the termination of our prior revolving credit facility. We recorded interest expense related to its settlement in the consolidated statement of operations for the three months ended March 31, 2014.

Foreign currency forward contracts

From time to time, we use foreign currency forward contracts to manage our exposure to changes in foreign exchange rates, as many of our projects generate cash flow in U.S. dollars and Canadian dollars. On February 20, 2014, we paid $0.4 million to terminate all of our remaining foreign currency forward contracts in connection with the termination of our prior revolving credit facility and recorded their settlement in foreign exchange gain in the consolidated statement of operations for the three months ended March 31, 2014.

Volume of forecasted transactions

We have entered into derivative instruments in order to economically hedge the following notional volumes of forecasted transactions as summarized below, by type, excluding those derivatives that qualified for the NPNS exemption as of the three months ended March 31, 2015 and the year ended December 31, 2014:

Deferred tax benefit from continuing operations		(5.7	)		(18.2	)

Total income tax benefit, net	$	(4.6	)	$	(16.9	)

Income tax benefit from continuing operations for the three months ended March 31, 2015 was $4.6 million. Expected income tax expense for the same period, based on the Canadian enacted statutory rate of 26%, was $5.2 million. The primary items impacting the tax rate for the three months ended March 31, 2015 were $2.9 million relating to a decrease in the valuation allowance, $2.4 million relating to operating in higher tax rate jurisdictions, $1.8 million relating to foreign exchange and $2.7 million of other permanent differences.

Income tax benefit for the three months ended March 31, 2014 was $16.9 million. Expected income tax benefit for the same period, based on the Canadian enacted statutory rate of 26%, was $8.1 million. The primary items impacting the tax rate for the three months ended March 31, 2014 were $10.7 million of capital losses recognized on tax restructuring, $5.2 million relating to operating in higher tax rate jurisdictions, $3.6 million relating to foreign exchange, and $4.4 million of other permanent differences. These items were partially offset by $15.1 million relating to a change in the valuation allowance.

As of March 31, 2015, we have recorded a valuation allowance of $165.7 million. The amount is comprised primarily of provisions against Canadian and U.S. net operating loss carryforwards. In assessing the recoverability of our deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon projected future taxable income in the United States and in Canada and available tax planning strategies.

10. Equity compensation plans

Long-term incentive plan ("LTIP")

The following table summarizes the changes in outstanding LTIP notional units during the three months ended March 31, 2015:

			Grant Date Weighted-Average Price per Unit

Outstanding at December 31, 2014	1,443,254		$	3.28
Granted	1,007,726			2.75
Reinvested	15,085			2.85
Forfeited	(63,499	)		4.19
Exercised	(597,406	)		3.61

Outstanding at March 31, 2015	1,805,160		$	2.85

Certain awards have a market condition based on our total shareholder return during the performance period as compared to a group of peer companies and, in some cases, Project Adjusted EBITDA per common share compared to budget. Compensation expense for notional units granted is recorded net of estimated forfeitures. See Note 16 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2014 for further details.

Transition Equity Participation Agreement

On January 22, 2015, we granted James J. Moore, Jr., our President, Chief Executive Officer and a Director of the Company, 523,256 transition notional shares subject to the terms of his employment agreement. Fifty percent of the transition notional shares granted to Mr. Moore with respect to fiscal year 2015 will vest upon the four-year anniversary of the date of grant, provided he remains employed by the Company upon the vesting date, and the remaining portion will vest on or any time after the two-year anniversary of the grant if the weighted average Canadian dollar closing price of our common shares on the TSX for at least three consecutive calendar months has exceeded the market price per common share determined as of January 22, 2015 ($2.58) by at least 50%.

11. Basic and diluted earnings (loss) per share

Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted average common shares outstanding during their respective period. Diluted earnings (loss) per share is computed including dilutive potential shares as if they were outstanding shares during the year. Dilutive potential shares include the weighted average number of shares, as of the date such notional units were granted, that would be issued if the unvested notional units outstanding under the LTIP were vested and redeemed for shares under the terms of the LTIP.

Because we reported a loss for the three months ended March 31, 2014, diluted earnings per share are equal to basic earnings per share as the inclusion of potentially dilutive shares in the computation is anti-dilutive.

Potentially dilutive shares from convertible debentures of 23.5 million and 27.7 million have been excluded from fully diluted shares in the three months ended March 31, 2015 and 2014, respectively, because their impact would be anti-dilutive. Potentially dilutive shares from LTIP notional units have been excluded from fully diluted shares in the three months ended March 31, 2014 because their impact would be anti-dilutive.

the performance of our operating segments based on Project Adjusted EBITDA which is defined as project income (loss) plus interest, taxes, depreciation and amortization (including non-cash impairment charges) and changes in fair value of derivative instruments. Project Adjusted EBITDA is not a measure recognized under GAAP and does not have a standardized meaning prescribed by GAAP and is therefore unlikely to be comparable to similar measures presented by other companies. We use Project Adjusted EBITDA to provide comparative information about project performance without considering how projects are capitalized or whether they contain derivative contracts that are required to be recorded at fair value. Our equity investments in unconsolidated affiliates are presented based on our share of Project Adjusted EBITDA in the reconciliation of Project Adjusted EBITDA to project income (loss). A reconciliation of Project Adjusted EBITDA to project income (loss) is included in the table below:

and North Island projects in the West segment. BC Hydro purchases electricity from the Mamquam, Moresby Lake, and Williams Lake projects in the West segment.

14. Guarantees

In connection with the tax equity investments in our Canadian Hills project, we have expressly indemnified the investors for certain representations and warranties made by a wholly-owned subsidiary with respect to matters which we believe are remote and improbable to occur. The expiration dates of these guarantees vary from less than one year through the indefinite termination date of the project. Our maximum undiscounted potential exposure is limited to the amount of tax equity investment less cash distributions made to the investors and any amount equal to the net federal income tax benefits arising from production tax credits. Upon closing of the sale of the Wind Projects, we will not be liable under the guarantee agreements.

We and our subsidiaries enter into various contracts that include indemnification and guarantee provisions as a routine part of our business activities. Examples of these contracts include asset purchases and sale agreements, including the Purchase Agreement to sell the Wind Projects, joint venture agreements, operation and maintenance agreements, and other types of contractual agreements with vendors and other third parties, as well as affiliates. These contracts generally indemnify the counterparty for tax, environmental liability, litigation and other matters, as well as breaches of representations, warranties and covenants set forth in these agreements.

15. Contingencies

Shareholder class action lawsuits

Massachusetts District Court Actions

On March 8, 14, 15 and 25, 2013 and April 23, 2013, five purported securities fraud class action complaints were filed by alleged investors in Atlantic Power common shares in the United States District Court for the District of Massachusetts (the "District Court") against Atlantic Power and Barry E. Welch, our former President and Chief Executive Officer and a former Director of Atlantic Power, in each of the actions, and, in addition to Mr. Welch, some or all of Patrick J. Welch, our former Chief Financial Officer, Lisa Donahue, our former interim Chief Financial Officer, and Terrence Ronan, our current Chief Financial Officer, in certain of the actions (the "Proposed Individual Defendants," and together with Atlantic Power, the "Proposed Defendants") (the "U.S. Actions").

The District Court complaints differed in terms of the identities of the Proposed Individual Defendants they named, as noted above, the named plaintiffs, and the purported class period they alleged (July 23, 2010 to March 4, 2013 in three of the District Court actions and August 8, 2012 to February 28, 2013 in the other two District Court actions), but in general each alleged, among other things, that in Atlantic Power's press releases, quarterly and year-end filings and conference calls with analysts and investors, Atlantic Power and the Proposed Individual Defendants made materially false and misleading statements and omissions regarding the sustainability of Atlantic Power's common share

dividend that artificially inflated the price of Atlantic Power's common shares. The District Court complaints assert claims under Section 10(b) and, against the Proposed Individual Defendants, under Section 20(a) of the Securities Exchange Act of 1934, as amended.

The parties to each District Court action filed joint motions requesting that the District Court set a schedule in the District Court actions, including: (i) setting a deadline for the lead plaintiff to file a consolidated amended class action complaint (the "Amended Complaint"), after the appointment of lead plaintiff and counsel; (ii) setting a deadline for Proposed Defendants to answer, file a motion to dismiss or otherwise respond to the Amended Complaint (and for subsequent briefing regarding any such motion to dismiss); and (iii) confirming that the Proposed Defendants need not answer, move to dismiss or otherwise respond to any of the five District Court complaints prior to the filing of the Amended Complaint. On May 7, 2013, each of six groups of investors (the "U.S. Lead Plaintiff Applicants") filed a motion (collectively, the "U.S. Lead Plaintiff Motions") with the District Court seeking: (i) to consolidate the five U.S. Actions (the "Consolidated U.S. Action"); (ii) to be appointed lead plaintiff in the Consolidated U.S. Action; and (iii) to have its choice of lead counsel confirmed. On May 22, 2013, three of the U.S. Lead Plaintiff Applicants filed oppositions to the other U.S. Lead Plaintiff Motions, and on June 6, 2013, those three Lead Plaintiff Applicants filed replies in support of their respective motions. On August 19, 2013, the District Court held a status conference to address certain issues raised by the U.S. Lead Plaintiff Motions, entered an order consolidating the five U.S. Actions, and directed two of the six U.S. Lead Plaintiff Applicants to file supplemental submissions by September 9, 2013. Both of those U.S. Lead Plaintiff Applicants filed the requested supplemental submissions, and then sought leave to file additional briefing. The Court granted those requests for leave and additional submissions were filed on September 13 and September 18, 2013.

On March 31, 2014, the Court entered an order consolidating the five individual U.S. Actions, appointing the Feldman, Shapero, Carter and Smith investor group (one of the six U.S. Lead Plaintiffs Applicants) as Lead Plaintiff and approving Lead Plaintiff's selection of counsel. The Court also granted the parties' joint motion regarding initial case scheduling and directed the parties to resubmit a proposed schedule that contains specific dates. In response to that directive, on April 7, 2014, Lead Plaintiff filed an application and proposed order, which sought an extension of the schedule contained in the joint motion. The application and proposed order requested that: (i) Lead Plaintiff be permitted to file an amended complaint on or before May 30, 2014, (ii) the Proposed Defendants be permitted to move to dismiss or otherwise respond to the amended complaint on or before July 29, 2014, (iii) Lead Plaintiff be permitted to file an opposition, if any, on or before September 24, 2014, and (iv) the Proposed Defendants be permitted to file a reply to Lead Plaintiff's opposition on or before November 13, 2014. Proposed Defendants did not object to the schedule proposed by Lead Plaintiff. On May 29, 2014, Lead Plaintiff filed a renewed application and proposed order, which sought another extension of the schedule, and on June 3, 2014, Lead Plaintiff and the Proposed Defendants jointly filed a stipulation and proposed order requesting the following revised schedule: (i) Lead Plaintiff be permitted to file an amended complaint on or before June 6, 2014, (ii) the Proposed Defendants be permitted to move to dismiss or otherwise respond to the amended complaint on or before August 5, 2014, (iii) Lead Plaintiff be permitted to file an opposition, if any, on or before October 6, 2014, and

(iv) the Proposed Defendants be permitted to file a reply to Lead Plaintiff's opposition on or before November 20, 2014. On June 3, 2014, the Court entered an order setting this requested schedule.

On June 6, 2014, Lead Plaintiff filed the amended complaint (the "Amended Complaint"). The Amended Complaint names as defendants Barry E. Welch and Terrence Ronan (the "Individual Defendants") and Atlantic Power (together with the Individual Defendants, the "Defendants") and alleges a class period of June 20, 2011 to March 4, 2013 (the "Class Period"). The Amended Complaint makes allegations that are substantially similar to those asserted in the five initial complaints. Specifically, the Amended Complaint alleges, among other things, that in Atlantic Power's press releases, quarterly and year-end filings and conference calls with analysts and investors, Defendants made materially false and misleading statements and omissions regarding the sustainability of Atlantic Power's common share dividend, which artificially inflated the price of Atlantic Power's common shares during the class period. The Amended Complaint continues to assert claims under Section 10(b) and, against the Individual Defendants, under Section 20(a) of the Securities Exchange Act of 1934, as amended. It also asserts a claim for unjust enrichment against the Individual Defendants. In accordance with the schedule referenced above, Defendants filed their motion to dismiss the consolidated (the "Motion to Dismiss") U.S. Action on August 5, 2014.

On September 30, 2014, citing Atlantic Power's September 16, 2014 announcement of changes to its dividend and its President and CEO transition, Lead Plaintiff filed a motion (the "Extension Motion") requesting a thirty-day extension of its October 6, 2014 deadline for filing its brief in opposition to the Motion to Dismiss, in which to determine whether to file a second amended complaint. On October 2, 2014, the Court entered an order (i) extending Lead Plaintiff's deadline to file its opposition to the Motion to Dismiss to October 10, 2014 and (ii) requiring Defendants to file their opposition to the Extension Motion by October 2, 2014. In accordance with this order, on October 2, 2014, Defendants filed their opposition to the Extension Motion. On October 10, 2014, Lead Plaintiff filed its opposition to the Motion to Dismiss (the "Opposition") and also filed a motion for leave to amend the Amended Complaint, attaching a proposed second amended complaint. On October 21, 2014, Lead Plaintiff and Defendants filed a joint scheduling motion requesting (i) November 7, 2014 as the deadline for Defendants to file their opposition to Lead Plaintiff's motion for leave to amend the Amended Complaint; (ii) November 24, 2014 as the deadline for Defendants to file their reply in further support of the Motion to Dismiss; and (iii) November 24, 2014 as the deadline for Lead Plaintiff to file its reply in further support of its motion for leave to amend the Amended Complaint. On October 22, 2014, the Court entered an order setting this requested schedule. Pursuant to that order, the Motion to Dismiss and Extension Motion were fully briefed on November 24, 2014. On January 22, 2015, the Court held oral argument on the Motion to Dismiss and Extension Motion.

On January 30, 2015, Lead Plaintiff filed a motion for leave to file a supplemental submission in opposition to Defendants' motion to dismiss (the "Motion for Leave"). The Court denied the Motion for Leave in an order entered on February 5, 2015, but permitted Lead Plaintiff to submit a brief letter identifying supplemental authorities. Lead Plaintiff filed that letter on February 9, 2015, and Defendants filed a response on February 10, 2015.

On March 13, 2015, the District Court entered an order granting Defendants' motion to dismiss and denying Lead Plaintiff's motion to amend the Amended Complaint, and on March 18, 2015, the District Court entered an order dismissing the Amended Complaint with prejudice. On April 16, 2015, Lead Plaintiff filed a notice of appeal to the United States Court of Appeals for the First Circuit. The Company will oppose that appeal.

Canadian Actions

On March 19, 2013, April 2, 2013 and May 10, 2013, three notices of action relating to Canadian securities class action claims against the Proposed Defendants were also issued by alleged investors in Atlantic Power common shares, and in one of the actions, holders of Atlantic Power convertible debentures, with the Ontario Superior Court of Justice in the Province of Ontario. On April 8, 2013, a similar claim issued by alleged investors in Atlantic Power common shares seeking to initiate a class action against the Proposed Defendants was filed with the Superior Court of Quebec in the Province of Quebec (the "Canadian Actions").

On April 17, May 22, and June 7, 2013, statements of claim relating to the notices of action were filed with the Ontario Superior Court of Justice in the Province of Ontario.

On August 30, 2013, the three Ontario actions were succeeded by one action with an amended claim being issued on behalf of Jacqeline Coffin and Sandra Lowry. As in the U.S. Action, this claim names the Company, Barry E. Welch and Terrence Ronan as Defendants. The Plaintiffs seek leave to commence an action for statutory misrepresentation under the Ontario Securities Act and assert common law claims for misrepresentation. The Plaintiffs' allegations focus on among other things, claims the Defendants made materially false and misleading statements and omissions in Atlantic Power's press releases, quarterly and year-end filings and conference calls with analysts and investors, regarding the sustainability of Atlantic Power's common share dividend that artificially inflated the price of Atlantic Power's common shares. The Plaintiffs seek to certify the statutory and common law claims under the Class Proceedings Act for security holders who purchased and held securities through a proposed class period of November 5, 2012 to February 28, 2013.

On October 4, 2013, the Plaintiffs delivered materials supporting their request for leave to commence an action for statutory misrepresentations and for certification of the statutory and common claims as class proceedings. These materials estimate the damages claimed for statutory misrepresentation at $197.4 million.

The Defendants and Plaintiffs subsequently exchanged responding and reply materials in respect of the leave and certification motions. These motions will be heard on May 20-21, 2015.

The proposed class action in Quebec is stayed until June 18, 2015.

Pursuant to the Private Securities Litigation Reform Act of 1995, all discovery is stayed in the U.S. Actions. Plaintiffs have not yet specified an amount of alleged damages in the U.S. Actions. As noted above, the plaintiffs in the Canadian Action have estimated their alleged statutory damages at $197.4 million. Because both the U.S. and Canadian Actions are in their early stages, Atlantic Power is

unable to reasonably estimate the possible loss or range of losses, if any, arising from this litigation. Atlantic Power intends to defend vigorously against each of the actions.

Other

In addition to the other matters listed, from time to time, Atlantic Power, its subsidiaries and the projects are parties to disputes and litigation that arise in the normal course of business. We assess our exposure to these matters and record estimated loss contingencies when a loss is likely and can be reasonably estimated. There are no matters pending which are expected to have a material adverse impact on our financial position or results of operations or have been reserved for as of March 31, 2015.

16. Subsequent events

On April 22, 2015, our indirect wholly-owned subsidiary, Ridgeline Energy LLC ("Ridgeline"), closed a transaction with CRE-Frontier Solar California LLC, ("CRE") a subsidiary of Centaurus Renewable Energy LLC, whereby CRE agreed to purchase 100% of Ridgeline's equity interests in Frontier Solar, LLC ("Frontier"), which is developing an approximately 20 MW solar electric generating facility in California, for net cash proceeds of $4.3 million. If Frontier achieves commercial operations and meets certain operating performance metrics, we could receive additional cash proceeds.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of the financial condition and results of operations of Atlantic Power should be read in conjunction with the interim consolidated financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q. All dollar amounts discussed below are in millions of U.S. dollars except per share amounts, or unless otherwise stated. The interim financial statements have been prepared in accordance with GAAP.

OVERVIEW

Atlantic Power owns and operates a diverse fleet of power generation assets in the United States and Canada. Our power generation projects sell electricity to utilities and other large commercial customers largely under long-term power purchase agreements ("PPAs"), which seek to minimize exposure to changes in commodity prices. As of March 31, 2015, our power generation projects in operation had an aggregate gross electric generation capacity of approximately 2,137 megawatts ("MW") in which our aggregate ownership interest is approximately 1,502 MW. Our current portfolio consists of interests in twenty-three operational power generation projects across nine states in the United States and two provinces in Canada. Eighteen of our projects are majority-owned subsidiaries. These totals exclude an aggregate 521 MW from our 100% ownership interest in Meadow Creek Project Company, LLC ("Meadow Creek"), our 99% ownership in Canadian Hills Wind, LLC ("Canadian Hills"), our 50% ownership interest in Rockland Wind Farm, LLC ("Rockland"), our 27.6% ownership interest in Idaho Wind Partners 1, LLC ("Idaho Wind") and our 12.5% ownership interest in Goshen Phase II, LLC ("Goshen") (collectively, the "Wind Projects"), for which we entered into an agreement to sell on March 31, 2015, and which are designated as assets held for sale and discontinued operations at March 31, 2015.

We sell the majority of the capacity and energy from our power generation projects under PPAs to a variety of utilities and other parties. Under the PPAs, we receive payments for electric energy sold to our customers (known as energy payments), in addition to payments for electric generation capacity (known as capacity payments). Our PPAs have expiration dates ranging from December 31, 2017 (at our North Bay and Kapuskasing projects, which accounted for 9% of Project Adjusted EBITDA for the year ended December 31, 2014) to December 31, 2037, and approximately 25% of our PPAs on a MW-weighted basis are scheduled to expire over the next five years. Pro forma for the sale of the Wind Projects, our weighted average remaining PPA life is approximately 8 years. We also sell steam from a number of our projects to industrial purchasers under steam sales agreements. Sales of electricity are generally higher during the summer and winter months, when temperature extremes create demand for either summer cooling or winter heating.

The majority of our natural gas, coal and biomass power generation projects have long-term fuel supply agreements, typically accompanied by fuel transportation arrangements. In most cases, the term of the fuel supply and transportation arrangements correspond to the term of the relevant PPAs and many of the PPAs and steam sales agreements provide for the indexing or pass-through of fuel costs to our customers. In cases where there is no pass-through of fuel costs, we often attempt to mitigate the market price risk of changing commodity costs through the use of hedging strategies.

We directly operate and maintain eighteen of our power generation projects. We also partner with recognized leaders in the independent power industry to operate and maintain our other projects, including Colorado Energy Management and Power Plant Management Services. Under these operation, maintenance and management agreements, the operator is typically responsible for operations, maintenance and repair services.

RECENT DEVELOPMENTS

Wind Sale

On March 31, 2015, Atlantic Power Transmission, Inc. ("APT"), our wholly-owned, direct subsidiary, entered into a definitive agreement (the "Purchase Agreement") with TerraForm AP Acquisition Holdings, LLC ("TerraForm"), an indirect subsidiary of TerraForm Power, Inc., to sell our wind generation projects for cash proceeds of approximately $350 million, subject to certain adjustments. Terraform will, subject to the terms and conditions in the Purchase Agreement, purchase from APT 100% of its direct membership interests in a holding company formed to facilitate the sale, thereby acquiring our indirect interests in its portfolio of wind projects consisting of five operating wind projects in Idaho and Oklahoma and representing 521 MW net ownership: Goshen (12.5% economic interest), Idaho Wind (27.6% economic interest), Meadow Creek (100% economic interest); Rockland Wind Farm ("Rockland") (50% economic interest, but consolidated on a 100% basis); and Canadian Hills (99% economic interest) (collectively, the "Wind Projects").

In addition to the receipt of approximately $350 million in cash proceeds, we will deconsolidate approximately $249 million of project debt (or approximately $275 million as adjusted for our proportional ownership of Rockland, Goshen North and Idaho Wind) and approximately $229 million of non-controlling interest related to tax equity interests at Canadian Hills and the minority ownership interests at Rockland and Canadian Hills. When the transaction closes, we expect to receive net proceeds of approximately $338 million in the aggregate, after estimated transaction fees and transaction-related taxes. We plan to use the proceeds to redeem the $310.9 million of 9% senior unsecured notes. The Wind Projects are accounted for as assets held for sale in the consolidated balance sheets at March 31, 2015 and December 31, 2014 and are a component of discontinued operations in the consolidated statements of operations for the three months ended March 31, 2015 and 2014.

The Purchase Agreement contains customary representations, warranties, covenants and indemnification provisions and the sale of the Wind Projects is subject to various closing conditions, including those described in our Current Report on Form 8-K filed with the Securities and Exchange Commission on April 1, 2015. The Purchase Agreement also contains certain termination rights for both APT and TerraForm, including if the closing does not occur within 90 days following the date of the Purchase Agreement, subject to an extension to 180 days under certain circumstances. The sale is expected to close by the end of the second quarter of 2015.

In connection with the Purchase Agreement, on March 31, 2015, we entered into a guaranty agreement (the "Guaranty Agreement"), under which we agreed to absolutely, unconditionally and irrevocably guarantee the full and prompt payment of all payment obligations of APT under the Purchase Agreement as and when they shall become due. APT and TerraForm have agreed to utilize representation and warranty insurance for coverage of certain indemnification obligations, subject to a cap and certain exclusions.

The foregoing description is qualified in its entirety by reference to the full text of the Purchase Agreement and the Guaranty Agreement, which are filed as exhibit 10.1 and 10.2, respectively, to this Quarterly Report on Form 10-Q, and incorporated by reference herein.

Frontier Sale

On April 22, 2015, our indirect wholly-owned subsidiary, Ridgeline Energy LLC ("Ridgeline'), closed a transaction with CRE-Frontier Solar California LLC ("CRE"), a subsidiary of Centaurus Renewable Energy LLC, whereby CRE agreed to purchase 100% of Ridgeline's equity interests in Frontier Solar, LLC ("Frontier"), which is developing an approximately 20 MW solar electric generating facility in California, for net cash proceeds of $4.3 million. If Frontier achieves commercial

operations and meets certain operating performance metrics, we could receive additional cash proceeds. We expect to record a $3.5 million gain on sale related to the transaction in the consolidated statement of operations for the three and six months ended June 30, 2015.

OUR POWER PROJECTS

The table on the following page outlines our portfolio of power generating assets in operation as of May 7, 2015, (exclusive of the Wind Projects, for which we have entered into an agreement to sell) including our interest in each facility. Management believes the portfolio is well diversified in terms of electricity and steam buyers, fuel type, regulatory jurisdictions and regional power pools, thereby partially mitigating exposure to market, regulatory or environmental conditions specific to any single region. Our customers are generally large utilities and other parties with investment-grade credit ratings, as measured by Standard & Poor's ("S&P"). For customers rated by Moody's, we substitute the corresponding S&P rating in the table below. Customers that have assigned ratings at the top end of the range of investment-grade have, in the opinion of the rating agency, the strongest capability for payment of debt or payment of claims, while customers at the lower end of the range of investment-grade have weaker capacity. Agency ratings are subject to change, and there can be no assurance that a ratings agency will continue to rate the customers, and/or maintain their current ratings. A security rating may be subject to revision or withdrawal at any time by the rating agency, and each rating should be evaluated independently of any other rating. We cannot predict the effect that a change in the

ratings of the customers will have on their liquidity or their ability to pay their debts or other obligations.

⁽⁵⁾: On January 20, 2015, we entered into an agreement with the Ontario Power Authority and its successor, the Independent Electricity System Operator ("IESO"), for the future operations of the Tunis facility. Subject to meeting certain technical modifications to the plant, gas delivery and other requirements, Tunis will operate under a 15-year agreement with the IESO commencing between November 2017 and June 2019. The new contract will require the plant to become fully dispatchable as opposed to its current baseload configuration. As such, Tunis will only provide electricity to the Ontario grid when required, thereby assisting to reduce the incidents of surplus baseload generation in the market. The new agreement provides the Tunis project with a fixed monthly payment which escalates annually according to a pre-defined formula while allowing it to earn additional energy revenues for those periods during which it is called upon to operate.

⁽¹⁾: See reconciliation and definition in Supplementary Non-GAAP Financial Information.

Consolidated project income decreased $4.2 million for the three months ended March 31, 2015, as compared to the three months ended March 31, 2014. This decrease was due to a $14.0 million decrease in revenue primarily resulting from the Tunis PPA expiring on December 31, 2014 and a $23.7 million decrease in the change in fair value of our interest rate and fuel derivative instruments. These decreases were offset by a $22.0 million decrease in project expenses resulting from lower fuel and maintenance costs as compared to the 2014 period. A detailed discussion of project (loss) income by segment is provided below. The discussion of Project Adjusted EBITDA by segment begins on page 48.

We had four reportable segments: East, West, Wind and Un-allocated Corporate. The Wind Projects, which make up the entirety of the Wind segment, are designated as assets held for sale and a component of discontinued operations. We have adjusted the prior period to reflect this reclassification. The segment classified as Un-allocated Corporate includes activities that support the executive and administrative offices, capital structure, costs of being a public registrant, costs to develop future projects and intercompany eliminations. These costs are not allocated to the operating segments when determining segment profit or loss. Project income (loss) is the primary GAAP measure of our operating results and is discussed below by reportable segment.

East

Project income for the three months ended March 31, 2015 decreased $9.4 million from the comparable 2014 period primarily due to:

•: decreased project income of $9.2 million at Nipigon due primarily to a negative $9.2 million non-cash change in the fair value of gas purchase agreements that are accounted for as derivatives;
•: decreased project income of $3.5 million at Tunis primarily due to the expiration of the project's PPA on December 31, 2014; and
•: decreased project income of $3.3 million at North Bay due primarily to a negative $2.7 million non-cash change in the fair value of gas purchase agreements that are accounted for as derivatives.

These decreases were partially offset by:

•: increased project income of $5.2 million at Curtis Palmer due primarily to lower project interest expense resulting from a prepayment of interest in connection with the redemption of the project's 5.9% Senior Notes in the comparable 2014 period.

West

Project income for the three months ended March 31, 2015 increased $7.1 million from the comparable 2014 period primarily due to:

•: increased project income of $2.6 million at North Island due primarily to decreased maintenance expenses as compared to the comparable 2014 period, during which the project underwent a scheduled turbine overhaul;
•: increased project income of $2.1 million at Mamquam due primarily to increased revenues caused by higher water levels than the comparable 2014 period and lower maintenance costs resulting from a scheduled outage in the comparable 2014 period; and
•: increased project income of $1.7 million at Williams Lake due primarily to higher energy revenues resulting from increased generation and lower maintenance costs due to a forced outage in the comparable 2014 period.

Un-allocated Corporate

Total project loss increased $1.9 million primarily due to increased development and administrative costs at Ridgeline as well as a $0.7 million non-cash change in the fair value of interest rate swap agreements.

Administrative and other expenses (income)

Administrative and other expenses (income) include the income and expenses not attributable to any specific project and is allocated to the Un-allocated Corporate segment. These costs include the activities that support the executive and administrative offices, treasury function, costs of being a public registrant, costs to develop or acquire future projects, interest costs on our corporate obligations, the impact of foreign exchange fluctuations and corporate taxes. Significant non-cash items that impact Administrative and other expenses (income), and that are subject to potentially significant fluctuations include the non-cash impact of foreign exchange fluctuations from period to period on the U.S. dollar equivalent of our Canadian dollar-denominated obligations and the related deferred income tax expense (benefit) associated with these non-cash items.

Table of Contents

Administration

Administration expense increased $2.3 million or 32% from the comparable 2014 period primarily due to $2.9 million of employee severance costs incurred in the first quarter of 2015 and a $0.8 million increase in business strategy and development costs, partially offset by a $1.7 million decrease in legal expenses which were incurred in the comparable 2014 period related to the U.S. Actions and Canadian Actions.

Interest, net

Interest expense decreased $40.8 million or 61% from the comparable 2014 period primarily due to $23.3 million of make-whole premiums paid to redeem the $150 million aggregate principal amount of the Series A Notes (the "Series A Notes") and the $75 million aggregate principal amount of the Series B Notes (the "Series B Notes") issued by Atlantic Power (US) GP, as well as $16.4 million of premiums paid and non-cash deferred financing costs written off for the repurchase of $140.1 million aggregate principal amount of the 9.0% Notes, each of which occurred in in the first quarter of 2014.

Foreign exchange gain

Foreign exchange gain increased $15.4 million or 92% from the comparable 2014 period primarily due to a $15.0 million increase in unrealized gain in the revaluation of instruments denominated in Canadian dollars and a $1.1 million decrease in unrealized loss on foreign exchange forward contracts, offset by a $0.6 million decrease in realized gains related to foreign currency transactions. The closing U.S. dollar to Canadian dollar exchange rate was 1.27 and 1.11 at March 31, 2015 and 2014, respectively, an increase of 9.2% in the three months ended March 31, 2015 compared to a decrease of 3.9% in the three months ended March 31, 2014. The average U.S. dollar to Canadian dollar exchange rate was 1.26 and 1.11 at March 31, 2015 and 2014, respectively, an increase of 8.6% in the three months ended March 31, 2015 compared to a decrease of 4.4% in the three months ended March 31, 2014.

Income tax expense

Discontinued operations

Loss for the Wind Projects, which are accounted for as a component of discontinued operations, was $12.3 million and $8.3 million for the three months ended March 31, 2015 and 2014, respectively. The decrease is primarily attributable to lower generation at the Meadow Creek and Rockland projects than in the comparable 2014 period.

Project Operating Performance

Two of the primary metrics we utilize to measure the operating performance of our projects are generation and availability. Generation measures the net output of our proportionate project ownership percentage in megawatt hours. Availability is calculated by dividing the total scheduled hours of a project less forced outage hours by the total hours in the period measured. The terms of our PPAs require our projects to maintain certain levels of availability. The majority of our projects were able to achieve their respective capacity payments. For projects where reduced availability adversely impacted capacity payments, the impact was not material for the three months ended March 31, 2015. The terms of our PPAs provide for certain levels of planned and unplanned outages.

Three months ended March 31, 2015 compared with three months ended March 31, 2014

Aggregate power generation for the three months ended March 31, 2015 decreased 9.9% from the comparable 2014 period primarily due to:

East

•: decreased generation in the East segment primarily due to a 73.0 and 68.5 net MWh decrease in generation at Tunis and Selkirk, respectively, whose PPAs expired in December 2014 and August 2014, respectively.

West

•: decreased generation in the West segment primarily due to a 99.3 net MWh decrease in generation at Frederickson due to lower dispatch resulting from warmer weather from the comparable 2014 period, partially offset by a 26.7 and 26.0 net MWh increase in generation at

Three months ended March 31, 2015 compared with three months ended March 31, 2014

Weighted average availability for the three months ended March 31, 2015 increased 5.3% to 97.6% from 2014 primarily due to:

•: increased availability in the East segment resulting from increased availability at Chambers and Kapuskasing, which underwent scheduled maintenance during the comparable 2014 period and at Piedmont, which had a lower amount of forced outage hours from the comparable 2014 period; and
•: increased availability in the West segment resulting from increased availability at Moresby Lake and Williams Lake, which underwent forced maintenance outages during the comparable 2014 period, and increased availability at North Island, which underwent scheduled maintenance during the comparable 2014 period.

Generation and availability statistics exclude the Wind Projects, which have been designated as held for sale and are a component of discontinued operations. For the three months ended March 31, 2015 and 2014, total generation and availability was 390.6 MWh and 97.9%, and 437.6 MWh and 93.2%, respectively. The 47.0 MWh decrease in generation is attributable to unfavorable winds at the Meadow Creek and Rockland projects as compared to the 2014 period.

Supplementary Non-GAAP Financial Information

A key measure we use to evaluate the results of our business is Free Cash Flow. Free Cash Flow is not a measure recognized under GAAP, does not have a standardized meaning prescribed by GAAP and therefore may not be comparable to similar measures presented by other issuers. We believe Free Cash Flow is a relevant supplemental measure of our ability to pay for additional debt reduction, fund internal or external growth, pay any dividends to our shareholders, or many other allocations of any available cash. A reconciliation of Free Cash Flow to cash flows from operating activities, the most directly comparable GAAP measure, is set out below under "Free Cash Flow." Free Cash Flow is comparable to Cash Available for Distribution, the non-GAAP measure we previously used to evaluate the results of our business. Investors are cautioned that we may calculate this measure in a manner that is different from other companies.

The primary factor influencing Free Cash Flow is cash distributions received from projects. These distributions are generally funded from Project Adjusted EBITDA generated by the projects, reduced

Table of Contents

by project-level debt service, capital expenditures, dividends paid on preferred shares of a subsidiary company, distributions to noncontrolling interests and adjusted for changes in project-level working capital and cash reserves. Project Adjusted EBITDA is defined as project income (loss) plus interest, taxes, depreciation and amortization (including non-cash impairment charges) and changes in fair value of derivative instruments. Project Adjusted EBITDA is not a measure recognized under GAAP and does not have a standardized meaning prescribed by GAAP and is therefore unlikely to be comparable to similar measures presented by other companies. We use Project Adjusted EBITDA to provide comparative information about project performance without considering how projects are capitalized or whether they contain derivative contracts that are required to be recorded at fair value. A reconciliation of Project Adjusted EBITDA to project income (loss) is provided under "Project Adjusted EBITDA" below and a reconciliation of Project Adjusted EBITDA by segment to project income (loss) by segment is provided in Note 13 to the consolidated financial statements of this Quarterly Report on Form 10-Q. Project Adjusted EBITDA for our equity investments in unconsolidated affiliates is presented on a proportionately consolidated basis in the table below. Investors are cautioned that we may calculate this measure in a manner that is different from other companies.

Three months ended March 31, 2015 compared with three months ended March 31, 2014

Project Adjusted EBITDA for the three months ended March 31, 2015 decreased $2.4 million or 5% from the comparable 2014 period primarily due to decreases in Project Adjusted EBITDA of:

•: $4.9 million at Tunis due to the expiration of the project's PPA on December 31, 2014; and
•: $4.7 million at Selkirk due to lower revenue from decreased generation from operating as a merchant facility since the expiration of its PPA in August 2014.

These decreases were partially offset by increases in Project Adjusted EBITDA of:

•: $4.0 million at Orlando primarily attributable to lower fuel expenses than the comparable 2014 period;
•: $2.2 million at Piedmont due primarily to legal expenses incurred in the comparable 2014 period related to the settlement of a noise complaint; and
•: $1.1 million at Morris due to lower fuel expenses than in the comparable 2014 period as a result of the reduction in the price of gas.

Project Adjusted EBITDA for the three months ended March 31, 2015 increased $5.9 million or 52% from the comparable 2014 period primarily due to increases in Project Adjusted EBITDA of:

•: $2.6 million at North Island which underwent a scheduled turbine maintenance outage in the comparable 2014 period;
•: $2.0 million at Mamquam due to $1.0 million in higher revenues resulting from increased water flows as well as a $1.0 million decrease in maintenance expense compared to the 2014 period, during which the project underwent turbine maintenance; and
•: $1.1 million at Williams Lake due to higher energy revenues resulting from increased generation and lower maintenance costs due to a forced outage in the comparable 2014 period.

Discontinued operations

Project Adjusted EBITDA excludes the Wind Projects which are designated as held for sale and are a component of discontinued operations for the three months ended March 31, 2015 and 2014. Project Adjusted EBITDA for the Wind Projects was $13.3 million and $17.8 million for the three months ended March 31, 2015 and 2014, respectively. The $4.5 million decrease is primarily attributable to a $2.9 million and $0.8 million decrease in Project Adjusted EBITDA at Meadow Creek and Rockland, respectively, resulting from unfavorable winds as compared to the 2014 period.

Project Adjusted EBITDA also excludes the Greeley project, which was sold in March 2014 and is accounted for as a component of discontinued operations for the three months ended March 31, 2014. Project Adjusted EBITDA for Greeley was ($0.1) million for the three months ended March 31, 2014.

Project Adjusted EBITDA for the three months ended March 31, 2015 decreased $1.3 million from the comparable 2014 period primarily due to increased development and administrative costs at Ridgeline.

Free Cash Flow

Free Cash Flow was $5.0 million and ($46.3) million for the three months ended March 31, 2015 and 2014, respectively, an increase of $51.3 million. The increase was due primarily to a $63.8 million increase in cash flows from operations and a $7.4 million decrease in project-level debt payments. This was partially offset by $21.3 million of payments on the Atlantic Power Limited Partnership's (the "Partnership") term loan facility. The net increase of $63.8 million in cash flows from operations is discussed in "Consolidated Cash Flows" below.

The table below presents our calculation of Free Cash Flow for the three months ended March 31, 2015 and 2014, and the reconciliation to cash flows from operating activities, the most directly comparable GAAP measure:

⁽⁴⁾: Free Cash Flow is not a recognized measure under GAAP and does not have any standardized meaning prescribed by GAAP. Therefore, this measure may not be comparable to similar measures presented by other companies. See "Supplementary Non-GAAP Financial Information" above. This table should be read together with the below table under "Consolidated Cash Flows" that sets forth Net cash provided by investing activities and Net cash used in financing activities for the three months ended March 31, 2015 and 2014.

Consolidated Cash Flows

The following table reflects the changes in cash flows for the periods indicated:

	Three months ended March 31,

Net cash provided by investing activities		7.6			71.6			(64.0	)
Net cash used in financing activities		(46.4	)		(21.5	)		(24.9	)

Operating Activities

Cash flow from our projects may vary from period to period based on working capital requirements and the operating performance of the projects, as well as changes in prices under the PPAs, fuel supply and transportation agreements, steam sales agreements and other project contracts, and the transition to merchant or re-contracted pricing following the expiration of PPAs. Project cash flows may have some seasonality and the pattern and frequency of distributions to us from the projects during the year can also vary, although such seasonal variances do not typically have a material impact on our business.

Cash flow from operating activities increased by $63.8 million for the three months ended March 31, 2015 from the comparable period in 2014. The increase in cash flows from operating activities is primarily due to $46.8 million of interest expense related to make-whole, accrued interest and premium payments made in connection with the redemption of the Series A and Series B Notes and the Curtis Palmer Notes in the comparable 2014 period and the repurchase of $140.1 million aggregate principal amount of the 9.0% Notes, also in the comparable 2014 period, and an $18.9 million increase in cash inflows for working capital due primarily to a $22.0 million increase in accruals and other liabilities related to the timing of payables and accruals.

Cash flow from operating activities includes the Wind Projects which are designated as held for sale and are a component of discontinued operations for the three months ended March 31, 2015 and 2014. Cash flow from operating activities for the Wind Projects was $10.8 million and $8.8 million for the three months ended March 31, 2015 and 2014, respectively.

Investing Activities

Cash flow from investing activities includes changes in restricted cash. Restricted cash fluctuates from period to period in part because non-recourse project-level financing arrangements typically require all operating cash flow from the project to be deposited in restricted accounts and then released at the time that principal payments are made and project-level debt service coverage ratios are met. As a result, the timing of principal payments on project-level debt causes significant fluctuations in restricted cash balances, which typically benefits investing cash flow in the second and fourth quarters of the year and decreases investing cash flow in the first and third quarters of the year.

Cash flows provided by investing activities for the three months ended March 31, 2015 were $7.6 million compared to cash flows provided by investing activities of $71.6 million for the three

Table of Contents

months ended March 31, 2014. The change is due to a $63.9 decrease in restricted cash primarily due to the release of the $75.0 million restricted cash requirement under the prior credit facility in the first quarter of 2014.

Cash flow from investing activities includes the Wind Projects which are designated as held for sale and are a component of discontinued operations for the three months ended March 31, 2015 and 2014. Cash flow from investing activities for the Wind Projects was $1.4 million and $1.2 million for the three months ended March 31, 2015 and 2014, respectively.

Financing Activities

Cash used in financing activities for the three months ended March 31, 2015 resulted in a net outflow of $46.4 million compared to a net outflow of $21.5 million for the comparable 2014 period. In the comparable 2014 period there were $35.0 million of net proceeds on corporate and project-level debt attributable to the proceeds from the Senior Secured Credit Facilities offset by repayments of the Series A and Series B Unsecured Notes, Senior Unsecured Notes of Curtis Palmer and partial repurchase of the 9.0% Notes as compared to $32.0 million of corporate and project-level debt repayments in the three months ended March 31, 2015. These increases were partially offset by a $38.3 million decrease in deferred financing costs primarily due to the issuance of the Senior Secured Credit Facility in the first quarter of 2014 and a $7.3 million decrease in dividends paid to common shareholders.

Total liquidity	$	216.1	$	232.8

Overview

Our primary source of liquidity is distributions from our projects and availability under our revolving credit facility. Our liquidity depends in part on our ability to successfully enter into new PPAs at projects when PPAs expire or terminate. PPAs in our portfolio have expiration dates ranging from December 31, 2017 (at our North Bay and Kapuskasing projects) to December 2037. We are currently in negotiations with counterparties regarding the renewal or entry into new power purchase agreements or may elect to operate certain facilities in the merchant market upon expiration of their PPAs. When a PPA expires or is terminated, it may be difficult for us to secure a new PPA, if at all, or the price received by the project for power under subsequent arrangements may be reduced significantly. As a result, this may reduce the cash received from project distributions and the cash available for further debt reduction, identification of and investment in accretive growth opportunities (both internal and external), to the extent available, and other allocation of available cash. See "Risk Factors—Risks Related to Our Structure—We may not generate sufficient cash flow to pay dividends, if and when declared by our board of directors, service our debt obligations or finance internal or external growth opportunities or fund our operations" in our Annual Report on Form 10-K for the year ended December 31, 2014.

We expect to reinvest approximately $11.5 million in 2015 (of which $1.3 million was reinvested in the three months ended March 31, 2015) in our portfolio in the form of project capital expenditures

Table of Contents

and incur $44.0 million of maintenance expenses (of which $5.2 million was incurred in the three months ended March 31, 2015). Such investments are generally paid at the project level. See "—Capital and Major Maintenance Expenditures" in our Annual Report on Form 10-K for the year ended December 31, 2014. We do not expect any other material or unusual requirements for cash outflows for 2015 for capital expenditures or other required investments. We believe that we will be able to generate sufficient amounts of cash and cash equivalents to maintain our operations and meet obligations as they become due for at least the next 12 months.

Impact of the New Senior Secured Credit Facilities

As previously disclosed with respect to the impact of the Senior Secured Credit Facilities in our Annual Report on Form 10-K for the year ended December 31, 2014 and 2013, due to the aggregate impact of the up-front costs resulting from the prepayments on our indebtedness further described in our Annual Report on Form 10-K for the year ended December 31, 2014, including the premium payment and charges for unamortized debt discount and fee expenses and premiums as part of the overall purchase price in respect of the repurchases of the 9.0% Notes in March 2014, which were reflected as interest expense in our 2014 first quarter results, through March 31, 2015 we did not satisfy the fixed charge coverage ratio test included in the restricted payments covenant of the indenture governing the 9.0% Notes. The fixed charge coverage ratio must be at least 1.75 to 1.00 and is measured on a rolling four quarter basis, including after giving effect to certain pro forma adjustments.

As of March 31, 2015, we are again in compliance with the fixed charge ratio test. During the period we were not in compliance, March 31, 2014 through March 31, 2015, dividend payments, in the aggregate, could not exceed the covenant's "basket" provision of the greater of $50 million and 2% of consolidated net assets (approximately $46.7 million at March 31, 2015) until we satisfied the fixed charge coverage ratio test. Through March 31, 2015, we declared cumulative dividends totaling approximately $35.4 million that were subject to the basket provision. As long as we remain in compliance with the ratio test, we are not subject to the basket provision. However, the basket does not reset if were to fall out of compliance at any point in the future. Dividends to shareholders are paid, if and when declared by, and subject to the discretion of, the board of directors.

⁽¹⁾: In addition to the annual principal payments described herein, the Credit Agreement requires payment of 50% of the excess cash flow of the Partnership and its subsidiaries. On May 5, 2014, we entered into interest rate swap agreements to mitigate the exposure to changes in LIBOR for $199.0 million notional amount ($172.4 million at March 31, 2015) of the $600.0 million ($520.2 million at March 31, 2015) outstanding aggregate borrowings. See Note 8, Accounting for derivative instruments and hedging activities for further details.

Project-Level Debt

Table of Contents

revenue-generating contracts of the projects. All project-level debt is non-recourse to us and substantially the entire principal is amortized over the life of the projects' PPAs. The following table summarizes the maturities of project-level debt. The amounts represent our share of the non-recourse project-level debt balances at March 31, 2015. Certain of the projects have more than one tranche of debt outstanding with different maturities, different interest rates and/or debt containing variable interest rates. Project-level debt agreements contain covenants that restrict the amount of cash distributed by the project if certain debt service coverage ratios are not attained. At May 5, 2015, all of our projects, except for Piedmont, were in compliance with the covenants contained in project-level debt. During the first quarter of 2014, Piedmont underwent forced maintenance outages that resulted in the project not meeting its debt service coverage ratio covenant as of March 31, 2015. We do not expect Piedmont to meet its debt service coverage ratio covenant or make distributions before 2017 at the earliest, due to continued operational issues that have resulted in higher forecasted maintenance and fuel expenses than initially expected. See Note 5, Long-term debt—Non-Recourse Debt .

The range of interest rates presented represents the rates in effect at March 31, 2015. The amounts listed below are in millions of U.S. dollars, except as otherwise stated.

⁽¹⁾: The projects listed do not include the Wind Projects which have been classified as held for sale and are a component of discontinued operations for the three months ended March 31, 2015 and 2014.
⁽²⁾: In June 2014, Chambers refinanced its project debt and issued (i) Series A (tax exempt) Bonds due December 2023, of which our proportionate share is $41.3 million and (ii) Series B (taxable) Bonds due December 2019, of which our proportionate share is $1.6 million. The above table does not include our $4.2 million proportionate share of issuance premiums.

Uses of Liquidity

Our requirements for liquidity and capital resources, other than operating our projects, consist primarily of principal and interest on our outstanding convertible debentures, senior notes and other corporate and project level debt, funding the repurchase of shares of our common stock (to the extent we choose to pursue any such repurchase), collateral and capital expenditures, including major maintenance and business development costs and dividend payments, if and when declared by our board of directors, to our common shareholders and preferred shareholders of a subsidiary company. We may fund future acquisitions with a combination of cash on hand, the issuance of additional corporate debt or equity securities and the incurrence of privately placed bank or institutional non-recourse operating level debt, although we can provide no assurances regarding the availability of public or private financing on acceptable terms or at all.

Capital and Maintenance Expenditures

Capital expenditures and maintenance expenses for the projects are generally paid at the project level using project cash flows and project reserves. Therefore, the distributions that we receive from the projects are made net of capital expenditures needed at the projects. The operating projects which we own consist of large capital assets that have established commercial operations. On-going capital expenditures for assets of this nature are generally not significant because most expenditures relate to planned repairs and maintenance and are expensed when incurred.

Table of Contents

We expect to reinvest approximately $11.5 million in 2015 (of which $1.3 million was reinvested in the three months ended March 31, 2015) in our portfolio in the form of project capital expenditures and incur $44.0 million of maintenance expenses (of which $5.2 million was incurred in the three months ended March 31, 2015). As explained above, these investments are generally paid at the project level. We believe one of the benefits of our diverse fleet is that plant overhauls and other expenditures do not occur in the same year for each facility. Recognized industry guidelines and original equipment manufacturer recommendations provide a source of data to assess maintenance needs. In addition, we utilize predictive and risk based analysis to refine our expectations, prioritize our spending and balance the funding requirements necessary for these expenditures over time. Future capital expenditures and maintenance expenses may exceed the projected level in 2015 as a result of the timing of more infrequent events such as steam turbine overhauls and/or gas turbine and hydroelectric turbine upgrades.

Scheduled maintenance outages during the three months ended March 31, 2015 occurred at such times that did not materially impact the facilities' availability requirements under their respective PPAs.

Recently Adopted and Recently Issued Accounting Guidance

Off-Balance Sheet Arrangements

As of March 31, 2015, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.

Table of Contents

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to financial market risk results primarily from fluctuations in interest and currency rates and fuel and electricity prices. There have been no material changes to our market risks as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

Table of Contents

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer have evaluated our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this report, and they have concluded that these controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There have been no changes in internal control over financial reporting during the three months ended March 31, 2015, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations of Disclosure Controls and Internal Control over Financial Reporting

Because of their inherent limitations, our disclosure controls and procedures and our internal control over financial reporting may not prevent material errors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to risks, including that the control may become inadequate because of changes in conditions or that the degree of compliance with our policies or procedures may deteriorate.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are party to legal proceedings, including securities class actions, from time to time. In particular, we and/or certain of our current and former officers have been named as defendants in various class action lawsuits. Due to the nature of these proceedings, the lack of precise damage claims and the type of claims we are subject to, we are unable to determine the ultimate or maximum amount of monetary liability or financial impact, if any, to us in these legal matters, which unless otherwise specified, seek damages from the defendants of material or indeterminate amounts.

Shareholder class action lawsuits

Massachusetts District Court Actions

Table of Contents

On June 6, 2014, Lead Plaintiff filed the amended complaint (the "Amended Complaint"). The Amended Complaint names as defendants Barry E. Welch and Terrence Ronan (the "Individual Defendants") and Atlantic Power (together with the Individual Defendants, the "Defendants") and alleges a class period of June 20, 2011 to March 4, 2013 (the "Class Period"). The Amended Complaint makes allegations that are substantially similar to those asserted in the five initial complaints. Specifically, the Amended Complaint alleges, among other things, that in Atlantic Power's press releases, quarterly and year- end filings and conference calls with analysts and investors, Defendants made materially false and misleading statements and omissions regarding the sustainability of Atlantic Power's common share dividend, which artificially inflated the price of Atlantic Power's common shares during the class period. The Amended Complaint continues to assert claims under Section 10(b) and, against the Individual Defendants, under Section 20(a) of the Securities Exchange Act of 1934, as amended. It also asserts a claim for unjust enrichment against the Individual Defendants. In accordance with the schedule referenced above, Defendants filed their motion to dismiss the consolidated (the "Motion to Dismiss") U.S. Action on August 5, 2014.

Table of Contents

Pursuant to that order, the Motion to Dismiss and Extension Motion were fully briefed on November 24, 2014. On January 22, 2015, the Court held oral argument on the Motion to Dismiss and Extension Motion.

Canadian Actions

On April 17, May 22, and June 7, 2013, statements of claim relating to the notices of action were filed with the Ontario Superior Court of Justice in the Province of Ontario.

The Defendants and Plaintiffs subsequently exchanged responding and reply materials in respect of the leave and certification motions. These motions will be heard on May 20-21, 2015.

The proposed class action in Quebec is stayed until June 18, 2015.

Table of Contents

unable to reasonably estimate the possible loss or range of losses, if any, arising from this litigation. Atlantic Power intends to defend vigorously against each of the actions.

Other than as described above, there were no material changes to legal proceedings disclosed in "Item 3. Legal Proceedings" of our Annual Report on Form 10-K for the year ended December 31, 2014.

ITEM 1A. RISK FACTORS

Other than as described below, there were no material changes to the risk factors disclosed in "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2014 (except to the extent additional factual information disclosed elsewhere in this Quarterly Report on Form 10-Q relates to such risk factors (including, without limitation, the matters discussed in "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations"). To the extent any risk factors in our Annual Report on Form 10-K for the year ended December 31, 2014 relate to the factual information disclosed elsewhere in this Quarterly Report on Form 10-Q, including with respect to our business plan and any updated to our business strategy, such risk factors should be read in light of such information.

There are risks and uncertainties associated with the pending sale of the Wind Projects.

There are a number of risks and uncertainties associated with our pending sale of the Wind Projects, including, among other things, the potential for an occurrence of an event, change or other circumstances which gives rise to the termination of the Purchase Agreement. There can be no assurance that the sale of the Wind Projects will be consummated in the timeframe or manner currently anticipated, or at all, that the conditions to closing of the sale of the Wind Projects will be satisfied or waived, that the termination rights of either party under the Purchase Agreement will not be triggered or that other events, including events outside of our control, will not intervene to delay or result in the termination of the sale. Any delay in closing or failure to close could subject us to a number of risks, including: (i) to the extent that the current market price of our common stock reflects an assumption that the sale of the Wind Projects will be consummated in the timeframe and manner currently anticipated, such market price may decline, (ii) that our relationships with customers, suppliers and employees may be damaged and our business harmed, (iii) that we may not be able to find another party interested in and able to purchase the Wind Projects and (iv) that even if an alternate purchaser is identified, it may not pay an equivalent price to what is proposed in the Purchase Agreement. In addition, pending the closing of the sale of the Wind Projects, the Purchase Agreement restricts APT and its affiliates from engaging in certain actions, including related to the solicitation of other purchasers, which could prevent us from pursuing opportunities that may arise prior to the closing of the sale of the Wind Projects.

MEMBERSHIP INTEREST PURCHASE AGREEMENT

This MEMBERSHIP INTEREST PURCHASE AGREEMENT (this “ Agreement ”), dated as of March 31, 2015, is made and entered into by and between ATLANTIC POWER TRANSMISSION, INC., a Delaware corporation (the “ Seller ”), and TERRAFORM AP ACQUISITION HOLDINGS, LLC, a Delaware limited liability company (the “ Buyer ”).

RECITALS

WHEREAS, as of the date hereof, the Seller is the record and beneficial owner of 100% of the authorized, issued and outstanding membership interests in TerraForm AP Holdings, LLC, a Delaware limited liability company (the “ Target ”), and the direct or indirect record and beneficial owner of the authorized, issued and outstanding membership interests identified in Section 4.8(b) of the Seller Disclosure Schedule with respect to the APT Entities and Minority-Interest Entities (collectively, the “ Membership Interests ”); and

WHEREAS, the Seller desires to sell to the Buyer, and the Buyer desires to purchase from the Seller, all of the Membership Interests on the terms and subject to the conditions set forth herein.

AGREEMENT

NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties intending to be legally bound hereby agree as follows:

ARTICLE I.
DEFINITIONS

1.1 Definitions . Capitalized terms used in this Agreement have the meanings ascribed to them by definition in this Agreement or in Annex A hereto.

1.2 Construction . All article, section, subsection, other subdivision, annex, schedule (including the Seller Disclosure Schedule and the Buyer Disclosure Schedule, as applicable), and exhibit references used in this Agreement are to articles, sections, subsections, other subdivisions, annexes, schedules (including the Seller Disclosure Schedule and the Buyer Disclosure Schedule, as applicable) and exhibits to this Agreement unless otherwise specified. The Seller Disclosure Schedule and the Buyer Disclosure Schedule attached to this Agreement constitute a part of this Agreement and are incorporated herein for all purposes. If a term is defined as one part of speech (such as a noun), it shall have a corresponding meaning when used as another part of speech (such as a verb). Unless the context of this Agreement clearly requires otherwise, (a) the singular shall include the plural and the plural shall include the singular wherever and as often as may be appropriate, (b) the use of any gender herein shall be deemed to include the other genders, (c) the words “include”, “includes” or “including” shall be deemed to be followed by the phrase “without limitation,” (d) the words “hereof,” “hereby,” “herein,” “hereunder” and similar terms in this Agreement shall refer to this Agreement as a whole and not

any particular section or article in which such words appear, and (e) any reference to any Law (or any section or other provision of any Law) means such Law (or such section or provision) as amended, modified, codified, replaced or reenacted, in whole or in part, and in effect from time to time. Currency amounts referenced herein, unless otherwise specified, are in United States Dollars. Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless Business Days are specified. All accounting terms used herein and not expressly defined herein shall have the respective meanings given to them under GAAP.

ARTICLE II.
PURCHASE AND SALE OF MEMBERSHIP INTERESTS

2.1 Purchase and Sale of the Membership Interests . Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, the Seller shall sell, transfer, convey, assign and deliver to the Buyer the Membership Interests free and clear of all Liens (other than Liens arising under applicable securities Laws), and the Buyer shall purchase and accept from the Seller, the Membership Interests.

2.2 Purchase Price .

(a) The aggregate consideration to be paid by the Buyer to the Seller for the Membership Interests (“ Purchase Price ”) shall be an amount in cash equal to the sum of Three Hundred Fifty Million Dollars ($350,000,000), plus the net result of (i) either adding the Lock-Box Adjustment if it is a positive number or subtracting the absolute value of the Lock-Box Adjustment if it is a negative number and (ii) adding either the Working Capital Overage, if any, or the Working Capital Underage, if any, as determined for the Closing Date. Notwithstanding anything to the contrary contained herein, the receipt by the APT Entities and Minority-Interest Entities of all revenues received in the Ordinary Course of Business will not be included in the calculation of Lock-Box Contributions.

(b) The Buyer shall pay to the Seller the Purchase Price on the Closing Date by wire transfer in immediately available funds to such account as the Seller designates in writing to the Buyer at least three (3) Business Days prior to the Closing Date.

2.3 Determination of Purchase Price .

(a) At least ten (10) Business Days prior to the Closing Date, the Seller shall deliver to the Buyer a certificate setting forth an estimate of the Purchase Price, which shall include the Seller’s calculation of the Lock-Box Adjustment, if any, along with any supporting work papers and documentation evidencing any transactions during the Lock-Box Period deemed to constitute a Lock-Box Contribution or Lock-Box Distribution, and the Seller’s calculation of any Working Capital Overage or Working Capital Underage, as applicable, (the “ Working Capital Estimate ” and, collectively with the Lock-Box Adjustment, the “ Adjustment Amount Estimate ”). Such certificate shall be prepared by the Seller in good faith and be accompanied by reasonably detailed supporting documentation. Within five (5) Business Days after the delivery of the Adjustment Amount Estimate by the Seller to the Buyer, the Buyer may object in good faith to the Adjustment Amount Estimate in writing. If the Buyer objects to the Adjustment Amount Estimate within such five (5) Business Day period, the Parties shall attempt

to resolve their differences by negotiation. If the Parties are unable to do so prior to the Closing Date (or if the Buyer does not object to the Adjustment Amount Estimate), the Purchase Price shall be adjusted at Closing by the amount of the Adjustment Amount Estimate not in dispute. The disputed portion shall be resolved in accordance with the provisions of Section 2.3(c) and paid as part of any Final Statement.

(b) The “ Adjustment Amount ” equals the sum of (i) Working Capital Overage or Working Capital Underage, as the case may be, and (ii) the difference between the Lock-Box Adjustment paid at the Closing and any adjustment thereto pursuant to this Section 2.3 . Within sixty (60) days after the Closing Date, the Buyer shall deliver to the Seller (i) a statement setting forth a consolidated balance sheet of the Target as of the Economic Interests Closing Date prepared in accordance with GAAP and the Seller’s historic practices applied on the same basis as applied in the preparation of the Working Capital Estimate and (ii) a statement showing in reasonable detail its calculation of Working Capital as of the Economic Interests Closing Date, its calculation of all Lock-Box Contributions and Lock-Box Distributions (if different from the Seller’s), and its calculation of any Adjustment Amount, together with supporting work papers (the “ Adjustment Statement ”) as of such Economic Interests Closing Date. The Adjustment Statement shall be prepared in accordance with GAAP and the Seller’s historic practices applied on the same basis as applied in the preparation of the Working Capital Estimate.

(c) During the forty-five (45) day period following the Seller’s receipt of the Adjustment Statement, the Seller and its advisors (including accountants) shall be provided access to the relevant books, records and employees of the APT Entities and the Minority-Interest Entities (to the extent in the Buyer’s possession or control) to the extent required in connection with their review of and any dispute with respect to the Adjustment Statement and the Buyer shall furnish the Seller with any other information that might be relevant to the calculation of the Adjustment Amount; provided that the Seller and its advisors (including accountants) shall have executed all release letters reasonably requested by the Buyer’s accountants in connection therewith. The Adjustment Statement shall become final and binding upon the Parties on the expiration of such forty-five (45) day period, unless the Seller gives written notice of its specific disagreement with respect to such Adjustment Statement (a “ Notice of Disagreement ”) to the Buyer prior to such date (the “ Review Period ”). Any Notice of Disagreement shall specify in reasonable detail the nature of any disagreement so asserted, along with a calculation and amount of the disputed item. Any items on the Adjustment Statement as to which the Seller has not given notice of objection will be deemed to have been agreed upon by the Parties. If a Notice of Disagreement is delivered to the Buyer within the Review Period with respect to the Adjustment Statement, then such Adjustment Statement (as revised in accordance with this sentence) shall become final and binding upon the Parties on the earlier of (A) the Buyer and the Seller resolving in writing any differences they have with respect to the matters specified in the applicable Notice of Disagreement and (B) the date any disputed matters are finally resolved in writing by the Accountant in accordance with this Section 2.3 . During the fifteen (15) day period following the delivery of the Notice of Disagreement, the Buyer and the Seller shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Notice of Disagreement and any resolution of the Parties during such time will be final and binding. If any items remain in dispute at the end of such fifteen (15) day period, the Parties shall, within fifteen (15) days, submit to the Accountant for

arbitration, in accordance with this Section 2.3(c) , only matters that remain in dispute and were properly included in the Notice of Disagreement in accordance with this Section 2.3(c) , in the form of a written brief. In the event that either Party fails to submit its brief regarding items in dispute within such time period, then the Accountant shall render a decision based solely on the evidence timely submitted by the other Party. The Accountant shall be a nationally recognized independent public accounting firm as shall be reasonably agreed upon by the Buyer and the Seller in writing. The Buyer or the Seller shall use commercially reasonable efforts to cause the Accountant to render a written decision resolving the matters submitted to the Accountant within fourteen (14) days of the receipt of such submission. The scope of the disputes to be resolved by the Accountant shall be limited to determining only those items in dispute. The Accountant’s decision shall be based solely on written submissions by the Buyer and the Seller and their respective Representative s and not by independent review. The Accountant shall not hold any hearings, hear any oral testimony or otherwise seek or require any other evidence. The Accountant may not assign a value greater than the greatest value for such item claimed by any Party or smaller than the smallest value for such item claimed by a Party. The resolution of disputed items by the Accountant shall constitute an arbitral award that is final, binding and non-appealable and upon which a judgment may be entered by a court having jurisdiction thereover. The Accountant shall also determine, as part of such dispute resolution, the respective liability of the Buyer and the Seller as to payment of the costs and expenses of such Accountant, based on the following formula: the Buyer and the Seller shall each pay the percentage of the costs and expenses of the Accountant in settling the disputed matters set forth in the Notice of Disagreement equal to (i) the aggregate amount of such disputed matters (as determined by reference to the potential impact of such disputed matters on the Purchase Price) submitted to the Accountant that are unsuccessfully disputed by such Party (as finally determined by the Accountant) divided by (ii) the aggregate amount of all such disputed matters (as determined by reference to the potential impact of such disputed matters on the Purchase Price) submitted to the Accountant. The Parties shall cooperate with each other and the Accountant regarding the resolution of any disagreement with respect to the Adjustment Statement, such cooperation to include reasonable access to books, records, facilities and personnel. This provision shall constitute the exclusive remedy of the Parties with respect to determination of the Final Statement. A “ Final Statement ” shall be, with respect to the Adjustment Statement: (i) such Adjustment Statement if no Notice of Disagreement is delivered to the Buyer during the Review Period or (ii) such Adjustment Statement as adjusted by (A) the written agreement of the Buyer and the Seller or (B) the Accountant in accordance with this Section 2.3 .

(d) If the Adjustment Amount as set forth on the Final Statement is greater than the Adjustment Amount Estimate applicable to such Final Statement, the Buyer shall, within ten (10) Business Days after such Final Statement becomes final and binding on the Parties, make payment of such difference to the Seller by wire transfer of immediately available funds as the Seller may direct together with interest of the amount of such difference at the Default Interest Rate accruing from the Closing Date to the date of payment. If the Adjustment Amount as set forth on a Final Statement is less than the Adjustment Amount Estimate applicable to such Final Statement, then the Seller shall, within ten (10) Business Days after such Final Statement becomes final and binding on the Parties, make payment to the Buyer by wire transfer of immediately available funds of the amount of such difference, together with interest of the amount of such difference at the Default Interest Rate accruing from the Closing Date to the date of payment.

(e) Following the Closing through the date the Adjustment Statement or Final Statement becomes final and binding on the Parties, the Buyer shall not take any action with respect to the accounting books and records of the Target, or the items reflected thereon, on which such Adjustment Statement is to be based, that is inconsistent with Seller’s past practices. During the period of time from and after the Closing Date through the date the Adjustment Statement becomes final and binding on the Parties, the Buyer shall afford, and shall cause the Target to afford, the Seller and any of their accountants, counsel or financial advisors retained in connection with the determination of the applicable Adjustment Amount in accordance with this Section 2.3 , upon reasonable notice and at reasonable times and in such manner as will not unreasonably interfere with the conduct of the business of the Target or any of the APT Entities or Minority-Interest Entities, direct access during normal business hours to all the books, contracts, personnel, Representative s (including the Target’s accountants) and records of the Target and such Representative s (including the work papers of the Target’s accountants) relevant to the preparation of the Adjustment Statement, and the determination of the Adjustment Amount in accordance with this Section 2.3 as Seller reasonably requests; provided that (i) the Seller and its advisors (including accountants) shall have executed all release letters reasonably requested by the Buyer’s accountants in connection therewith, (ii) the Buyer shall have the right to have a Representative present for any such access; and (iii) the Buyer shall not be required to provide access to any information that is (A) subject to attorney-client or other applicable privilege to the extent doing so would reasonably be expected to cause such privilege to be waived, or (B) prohibited by applicable Law. The Seller shall treat all information obtained from or on behalf of the Buyer as Confidential Information in accordance with the terms hereof.

2.4 Closing . The Closing will take place at the offices of Morgan, Lewis & Bockius LLP, One Federal Street, Boston, MA 02110, or at such other place as the Buyer and the Seller mutually agree, at 10:00 A.M. local time, on the Closing Date.

The representations and warranties of the Seller and the Buyer contained in Articles III , IV and V, as applicable, or in any certificate delivered pursuant to Section 2.5(d) and Section 2.6(c) shall survive the Closing for a period of until 5:00 p.m. EST on the date that is eighteen (18) months following the Closing Date (the “ Survival Period ”), except that the Fundamental Representations of the Seller and the Fundamental Representations of the Buyer shall survive until sixty (60) days after the expiration of the applicable statute of limitations period with respect to the matters covered thereby. The covenants which by their terms do not contemplate performance after the Closing shall terminate as of the Closing. The covenants which by their terms contemplate performance after the Closing shall survive the Closing in accordance with their respective terms.

9.2 Indemnification.

(a) Indemnification of the Seller . After the Closing, the Buyer shall indemnify and hold harmless the Seller (and its directors, managers, officers, employees, agents, Affiliates, successors, and assigns) from and against any and all Losses based upon, arising out of or incurred with respect to (i) the breach of any of the Buyer’s representations and warranties contained in Article V or failure of any certificate delivered at the Closing to be true and correct

in all respects as of the Closing Date, or (ii) any breach or nonperformance of any covenant or obligation to be performed by the Buyer hereunder or under any agreement executed in connection herewith.

(b) Indemnification of the Buyer . After the Closing, the Seller shall indemnify and hold harmless the Buyer (and its respective directors, officers, employees, agents, Affiliates, successors, and assigns including the Target) (the “ Buyer Indemnitees ”) from and against any and all Losses based upon, arising out of or incurred with respect to:

(i) the breach of the Seller’s representations and warranties in Article III or Article IV of this Agreement or failure of any certificate delivered by the Seller at the Closing to be true and correct in all respects as of the Closing Date, and

(ii) any breach or nonperformance of any covenant or obligation to be performed by the Seller hereunder or under any agreement executed in connection herewith.

(c) Limitations on Indemnification Obligations . The rights of the Buyer Indemnitees to indemnification pursuant to the provisions of Section 9.2(b) are subject to the following limitations:

(i) the amount of any Loss subject to indemnification by the Seller hereunder or of any Claim therefor shall be reduced by any and all amounts actually recovered by the Buyer Indemnitee from the following collateral sources (collectively, the “ Collateral Sources ”): (i) any insurance proceeds actually received by the Buyer Indemnitees on account of such Loss, net of expenses paid to third parties in procuring any such recovery, and (ii) any Tax benefit actually realized by the Buyer Indemnitees as a result of the event or circumstances giving rise to such Loss. In the event that the Buyer Indemnitees obtain any recovery from one or more Collateral Sources or any other Person alleged to be responsible for any Losses, subsequent to an indemnification payment made hereunder, then such Buyer Indemnitee shall promptly reimburse the Seller for any payment made or expense incurred by Seller in connection with providing such indemnification up to the amount received by the Buyer Indemnitee, (net of direct collection expenses and Taxes), or, if a Loss has not yet been determined or paid by the Seller, the Seller’s indemnification obligations in respect of such Loss shall be reduced by the aggregate amount of the recovery from any Collateral Sources or any other Person alleged to be responsible for any Losses (net of direct collection expenses and Taxes);

(ii) the Buyer Indemnitees will not be entitled to recover Losses pursuant to Section 9.2(b)(i) unless and until the aggregate Losses incurred by the Buyer Indemnitees pursuant to Section 9.2(b)(i) exceed one and one-half percent (1.5%) of the Purchase Price in the aggregate (the “ Deductible ”) (after which the R&W Insurance Policy, or the Seller, as applicable, will be obligated to indemnify the Buyer Indemnitees, subject to the limitations set forth herein, from and against all Losses in excess of the Deductible);

(iii) the Buyer Indemnitees shall be responsible for any and all Losses up to the amount of the Retention (as such term is defined in the R&W Insurance Policy) under the R&W Insurance Policy. The sole source of funds to recover for any Losses arising from a breach of the Seller’s representations in Section 4.14(d) shall be the R&W Insurance Policy.

Recourse for Losses that were specifically excluded from coverage under the R&W Insurance Policy as set forth in Section 4 of the R&W Insurance Policy on the day coverage under the R&W Insurance Policy became effective (the “ Excluded Matters ”) shall be to the Seller Parent Guaranty. With respect to Other R&W Insured Losses (as defined below), Buyer shall notify Seller if it intends to seek recourse under the Seller Parent Guaranty before initiating a claim under the R&W Insurance Policy. If the Buyer elects not to seek recourse to the Seller Parent Guaranty then the Buyer’s sole recourse for Other R&W Insured Losses shall be the R&W Insurance Policy. If, and only if, Buyer notifies Seller that it intends to seek recourse to the Seller Parent Guaranty, shall the procedures provided by Sections 9.2(c)(iv) and (v) apply;

(iv) Upon the Insurer (as such term is defined in the R&W Insurance Policy) acknowledging that the Retention has been fully satisfied, the R&W Insurance Policy shall be the initial source of funds to recover for any other Losses for which the Buyer Indemnitees are entitled to indemnification in respect of Section 9.2(b) (the “ Other R&W Insured Losses ”). With respect to the Other R&W Insured Losses, in the event that (A) the remaining available Limit of Liability (as such term is defined in the R&W Insurance Policy) under the R&W Insurance Policy is insufficient to fully indemnify the Buyer Indemnitees for such Other R&W Insured Losses as a consequence of such Limit of Liability being wholly or partially exhausted (the “ Excess Other R&W Insured Losses ”), the Buyer shall, subject to the other terms, conditions and limitations set forth herein, have recourse to the Seller Parent Guaranty for such Excess Other R&W Insured Losses; and/or (B) the first dispositive order or determination of a court with jurisdiction over the matter determines that the Insurer is not obligated to pay the full amount of such Losses claimed in good faith by the Buyer Indemnitees (the “ Disputed Other R&W Insured Losses ”), the Buyer shall, subject to the other terms, conditions and limitations set forth herein, have recourse to the Seller Parent Guaranty for such Disputed Other R&W Insured Losses, subject to and only in the event that the Buyer Indemnitees fully comply with the conditions set forth in Section 9.2(d)(v) ;

(v) With respect to any Claim for indemnification for which Buyer notified Seller of its intent to seek recourse against the Seller Parent Guaranty, the Buyer Indemnitees shall have no right to recover under the Seller Parent Guaranty unless:

(A) the Buyer Indemnitees seek and obtain the Seller’s consent and approval of the form of such Claim Notice seeking coverage for any Other R&W Insured Losses prior to submitting such Claim Notice under the R&W Insurance Policy;

(B) the Buyer Indemnitees seek and obtain the Seller’s consent and approval of any coverage counsel retained by the Buyer Indemnitees to prosecute such claim for coverage for any Other R&W Insured Losses (“ Retained Counsel ”);

(C) the Buyer Indemnitees seek and obtain the Seller’s consent and prior approval with respect any and all material correspondence to the Insurer from the Buyer Indemnitees regarding the Buyer Indemnitees’ claims for coverage for such Other R&W Insured Losses;

(D) the Buyer Indemnitees seek and obtain the Seller’s consent and approval prior to the commencement of any litigation or other dispute resolution procedure

against the Insurer in connection with such Other Insured R&W Losses, including as to the forum and venue of such litigation dispute resolution procedure;

(E) the Seller is provided draft copies of all pleadings, briefs, discovery requests, other court papers or correspondence which relate or pertain to the Buyer Indemnitees’ claims for coverage for the Other R&W Insured Losses;

(F) the Buyer Indemnitees seek and obtain the Seller’s consent and prior approval with respect to all material positions in such pleadings, briefs, discovery requests, other court papers or correspondence regarding the Buyer Indemnitees’ claims for coverage for such Other R&W Insured Losses;

(G) at the Seller’s request, Retained Counsel resists the production of all documents or things or the providing of any information which the Seller asserts would not properly be discoverable, and uses its best efforts to ensure that the Seller’s documents and witnesses need only be produced in compliance with the subpoena power or governing rules of court or arbitration wherein such action is pending, and shall produce documents and other information in compliance with such rules and/or the orders such court or arbitration panel may issue pertaining thereto; and

(H) the Buyer Indemnitees’ seek and obtain the consent and approval of the Seller in pursuing or entering into any settlement with respect to any Other R&W Insured Losses, and to the extent such settlement results in payment by the Insurer of an amount less than the full amount of such Other R&W Insured Losses claimed by the Buyer Indemnitees in good faith, the Buyer Indemnitees expressly waive any right to seek recovery from the Seller Parent Guaranty for such deficiency.

In implementing subsections (A) through (H) above: (1) the Seller shall be solely responsible for the costs and expenses of its actions, (2) the Seller shall take no actions, or fail to take any action, that prejudices the claim of the Buyer; and (3) the Seller shall not have the right to determine whether to file a claim for coverage under the R&W Insurance Policy; provided that the Buyer agrees that the Seller shall be entitled to associate in the prosecution, negotiation and settlement of a claim for coverage filed by the Buyer Indemnitees’ for Other R&W Insured Losses under the R&W Insurance Policy;

(vi) except with respect to Losses related to breaches of the Fundamental Representations of the Seller, the aggregate indemnification obligation of the Seller pursuant to Section 9.2(b)(i) shall in no event exceed fifteen percent (15%) of the Purchase Price (it being understood that, except with respect to Losses related to breaches of the Fundamental Representations of the Seller, any amounts received by the Buyer Indemnitees pursuant to the R&W Insurance Policy shall be allocated in satisfaction of such capped limit of liability);

(vii) notwithstanding anything to the contrary set forth herein, (x) the cumulative indemnification obligations of the Seller under this Agreement for a breach of Seller’s representation in Section 4.13(d) , shall be no greater than the Buyer’s portion of the “Maximum Recapture Equity Contribution Commitment” as defined in the Recapture Guaranty Replacement Documentation; and (y) the cumulative indemnification obligations of the Seller

under this Agreement shall in no event exceed the Purchase Price (as adjusted pursuant to Section 2.3 ); provided , that for the avoidance of doubt, Seller shall have no liability under this Agreement for a breach of its representation in Section 4.13(d) , to the extent of any payment made by Seller or any of Seller’s Affiliates under the Recapture Guaranty Replacement Documentation; and

(viii) notwithstanding anything to the contrary set forth herein, (x) the cumulative indemnification obligations of the Buyer under this Agreement for a breach of Buyer’s representation in Section 5.9 , shall be no greater than the Seller’s portion of the “Maximum Recapture Equity Contribution Commitment” as defined in the Recapture ECA AP Guarantees and the Recapture ECA Veolia Guarantees; and (y) the cumulative indemnification obligations of the Buyer under this Agreement with respect to all other matters shall in no event exceed the Purchase Price (as adjusted pursuant to Section 2.3 ); provided that for the avoidance of doubt, Buyer shall have no liability under this Agreement for a breach of its representation in Section 5.9 , to the extent of any payment made by Buyer or any of Buyer’s Affiliates under the Recapture Guaranty Replacement Documentation.

(d) Additional Indemnity Provisions . The indemnification obligations of the Buyer and the Seller hereunder shall be subject to the following terms and conditions:

(i) From and after the Closing, the sole recourse and exclusive remedy of the Buyer and the Seller against each other arising out of this Agreement or any certificate delivered in connection with this Agreement, or otherwise arising from the Buyer’s acquisition of the Membership Interests, shall be to assert a Claim for indemnification under the indemnification provisions of this Article IX .

(ii) Notwithstanding Section 9.2(d)(i) , nothing in this Agreement shall operate to (i) relieve a Party of any liability for willful misconduct or (ii) limit the rights of the Parties with respect to intentional or willful misrepresentation of material facts regarding the representations and warranties made in Article III , Article IV or Article V , as applicable, of this Agreement (in each case, as qualified by the Seller Disclosure Schedule or the Buyer Disclosure Schedule, as applicable) or in any certificate delivered pursuant hereto which constitute common law fraud under applicable Laws.

(iii) For the purposes of determining whether there has been a breach or an inaccuracy in respect of any representation or warranty for the purpose of indemnification under this Section 9.2 , all Claims for Losses arising out of the same facts, events or circumstances resulting in such inaccuracy or breach shall be treated as a single Claim.

(iv) To the extent that an Indemnifying Party has discharged any Claim for indemnification hereunder, the Indemnifying Party shall be subrogated to all rights of the Indemnified Party against any Person to the extent of the Losses that relate to such Claim. Any Indemnified Party shall, upon written request by the Indemnifying Party following the discharge of such Claim, execute an instrument reasonably necessary to evidence such subrogation rights.

(v) In the event that any Party to this Agreement proposes to make any Claim for indemnification pursuant to this Section 9.2 , or would have the right to make a Claim

for indemnification but for the minimum or maximum limitations on indemnification contained in Section 9.2(b) , the Party making the Claim (or with such right) (the “ Indemnified Party ”) shall promptly deliver on or prior to the date upon which the applicable representations and warranties or covenants expire pursuant to the terms of this Agreement and within a reasonable time of discovery of the breach of or nonperformance of any covenant or obligation to be performed under this Agreement, a certificate signed by the party making the Claim or an officer of the party making the Claim (the “ Claim Certificate ”) to the Seller or the Buyer, whichever is applicable (such party from whom indemnification is sought the “ Indemnifying Party ”), which Claim Certificate shall (A) state the occurrence giving rise to the Claim; (B) specify the section of this Agreement under which such Claim is made; and (C) specify in reasonable detail each individual item of Loss or other Claim, including the section of this Agreement under which such Claim is made, the amount thereof if reasonably ascertainable, the date such Loss or liability was incurred, properly accrued or is anticipated, the basis for any anticipated Loss or liability and the nature of the misrepresentation, breach of warranty or the Claim to which such Loss or liability is related. The Indemnified Party making the Claim shall state only what is required in subsections (A)-(C) above and shall not admit or deny the validity of the facts or circumstances out of which such Claim arose.

(vi) Any indemnity payment made under this Agreement following the Closing shall be treated by the Parties hereto as an adjustment to the Purchase Price for the Membership Interests for Tax purposes, and the Parties agree to report such payments consistent therewith to the extent permitted under applicable Law.

(vii) The obligations to indemnify and hold harmless pursuant to Section 9.2(a) and Section 9.2(b) shall survive the Closing for the periods set forth in Section 9.1 , except for Claims for indemnification pursuant to such sections asserted prior to the end of such periods, which Claims shall survive with the final resolution thereof.

(viii) Each Party shall use its commercially reasonable efforts to mitigate its Losses (including by using such efforts to recover any insurance as may be available with respect to such Loss) upon and after becoming aware of any event which would reasonably be expected to give rise to any Losses; provided , however , that the foregoing shall not be deemed to impose any obligation or duty to initiate legal proceedings to seek such recovery.

(ix) NOTWITHSTANDING ANYTHING TO THE CONTRARY ELSEWHERE IN THIS AGREEMENT, NO PARTY HERETO SHALL, UNDER ANY CIRCUMSTANCE, HAVE ANY LIABILITY TO ANY OTHER PARTY FOR ANY INCIDENTAL DAMAGES, SPECIAL DAMAGES, EXEMPLARY DAMAGES, CONSEQUENTIAL DAMAGES, INCLUDING CONSEQUENTIAL DAMAGES CONSISTING OF BUSINESS INTERRUPTION, DIMINUTION IN VALUE, LOST PROFITS OR LOST ASSETS, OR PUNITIVE DAMAGES, EXCEPT WITH RESPECT TO THIRD-PARTY CLAIMS IF SUCH DAMAGES ARE INCLUDED AS PART OF SUCH CLAIM.

(e) Defense of Third Party Claims and Extension of Statute of Limitations.

(i) With respect to the Excluded Matters and/or any Other R&W Insured Losses, the Indemnified Party shall promptly give written notice (which such written

notice shall state in reasonable detail the nature of any such claim for indemnification and the provisions of this Agreement upon which such claim for indemnification is made) hereunder to the Indemnifying Party after obtaining notice of any claim as to which recovery may be sought against the Indemnifying Party because of the indemnity in this Article IX , and, if such indemnity obligation shall arise from the claim of a third party, shall permit the Indemnifying Party to assume the defense of any such claim and any litigation resulting from such claim; provided , however , that the Indemnifying Party shall not have the right to assume control of the defense of any claim (i) to the extent that the object of such claim for indemnification is to obtain an injunction, restraining order, declaratory relief or other non-monetary relief against the Indemnified Party which, if successful, would materially adversely affect the business, operations, assets, or financial condition of the Indemnified Party (ii) if the named parties to any such action or proceeding (including any impleaded parties) include both the Indemnified Parties and the Indemnifying Parties and the former shall have been advised in writing by counsel (with a copy to the Indemnifying Parties) that there are one or more legal or equitable defenses available to them that are different from or additional to those available to Indemnifying Parties (in which event each shall have the right to utilize counsel of their own choosing), or (iii) if such action or proceeding involves, or could reasonably be expected to involve liability that would constitute a material adverse effect on the Indemnified Parties. Failure by the Indemnifying Party to notify an Indemnified Party of its election to defend any such claim or action by a third party within thirty (30) days after notice thereof shall have been given to the Indemnifying Party shall be deemed a waiver by the Indemnifying Party of its right to defend such claim and the Indemnifying Party shall pay the reasonably incurred out-of-pocket cost and expense of the Indemnified Party to defend such claim. The Indemnified Party shall (unless the Indemnifying Party assumes the defense thereof) keep the Indemnifying Party reasonably apprised of any significant developments relating to any such claim.

(ii) If the Indemnifying Party shall assume the defense of any such claim by a third party or litigation resulting therefrom after receipt of notice from such Indemnified Party, (i) the Indemnifying Party shall not, in the defense of such claim or any litigation resulting therefrom, consent to entry of any judgment (other than a judgment of dismissal on the merits without costs) or agree to any settlement thereof except with the written consent of the Indemnified Party (such consent not to be unreasonably withheld, conditioned or delayed) and (ii) anything in this Section 9.2(e) to the contrary notwithstanding, the Indemnified Party may, with counsel of its choice and at its expense, participate in the defense of any such claim or litigation.

(iii) If the Indemnifying Party shall not assume the defense of any such claim by a third party or litigation resulting therefrom after receipt of notice from such Indemnified Party, the Indemnified Party may defend against such claim or litigation in such manner as it deems appropriate; provided that the Indemnified Party may not settle such claim or litigation without the prior written consent of the Indemnifying Party (such consent not to be unreasonably withheld, conditioned or delayed).

Each arbitrator shall be a retired judge or a practicing attorney with no less than 15 years of experience as such and shall be experienced in arbitration and with disputes relating to the subject matter to be arbitrated. For the avoidance of doubt, the arbitral tribunal shall maintain all proceedings in confidence, shall resolve all disputes in accordance with the Laws of the State of New York and shall not assume the powers of an amiable compositeur or decide ex aequo et bono. Except in accordance with any express exception contained in this Agreement, each party hereby irrevocably waives and foregoes any right to recover punitive, exemplary or special damages with respect to any Dispute as set forth in Section 9.2(d)(ix) , and the Parties hereby agree that the arbitrators are not empowered to award damages except in accordance with the express limitations contained in this Agreement (including Section 9.2(d)(ix) ).
