Partnership (&ldquo;APLP Holdings&rdquo;), a wholly-owned subsidiary of Atlantic Power Corporation (the &ldquo;Company&rdquo;),
entered into the Sixth Amendment (the &ldquo;Sixth Amendment&rdquo;) to the Credit and Guaranty Agreement, dated as of April 13,
2016 (as amended prior to the Sixth Amendment, the &ldquo;Credit Agreement&rdquo;), among APLP Holdings, the Company and certain
subsidiaries of APLP Holdings, as guarantors, Goldman Sachs Lending Partners LLC, as administrative agent and collateral agent,
and the other lenders and L/C issuers party thereto.</P>

<P STYLE="text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">The Sixth Amendment (i) provides for an
extension of the Revolving Commitment (as defined in the Credit Agreement) to be co-terminus with the term loan with a maturity
date of April 21, 2025; (ii) reduces the Revolving Commitment (as defined in the Credit Agreement) from $200 million to $180 million;
and (iii) provides an accordion feature permitting expansion of the Revolving Commitment (as defined in the Credit Agreement) without
requiring any subsequent consent or approval of the lenders, subject to approval of the two letter of credit issuer banks and increased
commitments by existing or new lenders, up to an aggregate principal amount of $210 million on the same terms and conditions as
the existing commitments. At February 29, 2020, the Company had no borrowings under the Revolver but was utilizing $78.2 million
for letters of credit.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">DEDHAM, MASSACHUSETTS &#8211; March 18,
2020 &#8211; Atlantic Power Corporation (NYSE: AT) (TSX: ATP) (&#8220;Atlantic Power&#8221; or the &#8220;Company&#8221;) announced
that on March 18, 2020, it executed an amendment to its senior secured revolving credit facility (&#8220;Revolver&#8221;). The
amendment provides for an extension of the Revolver maturity date to April 2025, to coincide with the maturity date of the senior
secured term loan (&#8220;Term Loan&#8221;). Both the Revolver and the Term Loan are at the Company&#8217;s APLP Holdings Limited
Partnership (&#8220;APLP Holdings&#8221;) subsidiary. At February 29, 2020, the Company had no borrowings under the Revolver but
was utilizing $78.2 million for letters of credit.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">In conjunction with the extension, the
Revolver capacity was reduced to $180 million from $200 million previously. The amendment allows an upsizing of the Revolver capacity
by up to $30 million, to a maximum aggregate amount of $210 million, subject to approval of the two letter of credit issuer banks
and increased commitments by existing or new lenders. Such an upsizing would not require a further amendment. There were no other
significant changes to the terms of the Revolver.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As previously disclosed in the Company&#8217;s
February 3, 2020 press release, the pricing of the Term Loan and Revolver was reduced to 250 basis points over LIBOR effective
January 31, 2020.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&#8220;We are pleased to have extended
our Revolver maturity by three years to coincide with the recent extension of our Term Loan maturity date. The Revolver extension,
together with our cash position, provides us with strong liquidity through April 2025,&#8221; said Terrence Ronan, Executive Vice
President and Chief Financial Officer of Atlantic Power. &#8220;To date the primary use of the Revolver has been to support letters
of credit, the need for which will be reduced following the sale of our Manchief plant in 2022. The balance of the Revolver is
available for other purposes such as asset acquisitions.&#8221;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&#8220;Today job one is to ensure the safety
and health of our employees while continuing to generate electric power for our customers. Our people and our plants are performing
terrifically in these tough times,&#8221; said James J. Moore, Jr., President and Chief Executive Officer of Atlantic Power. &#8220;On
the financial front, the actions that we have taken over the past several years to reduce costs and repay debt enable Atlantic
Power to withstand difficult environments, in the power markets or more broadly. The extension of our Revolver to match the recent
extension of our Term Loan maturity is a good outcome for us.&#8221;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Mr. Moore continued, &#8220;We have highly
contracted EBITDA and operating cash flow. More than 95% of our cumulative EBITDA and operating cash flow through 2024 is generated
under Power Purchase Agreements (PPAs) with an average remaining term of approximately six years. These PPAs are predominantly
with investment grade counterparties. We plan to continue allocating the majority of this strong cash flow to debt repayment, and
expect to amortize the balance of our Term Loan by the April 2025 maturity. During this five-year period we expect to generate
significant discretionary cash flow after debt repayment, as we noted on our fourth quarter 2019 conference call.&#8221;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&#8220;After years of rebuilding our financial
strength, we are now well positioned for periods of market turmoil. We invested $45 million in the acquisition of biomass and hydro
projects (and project interests) in 2018 and 2019. These acquisitions are producing strong returns in line with our expectations.
We stand ready to do more acquisitions if and when values are compelling. We also have repurchased $6.7 million of common shares
and Cdn$8.4 million (approximately US$6.0 million equivalent) of preferred shares under our normal course issuer bid this year
to date.&#8221;</P>

with the extension of the Revolver as an expense in the first quarter of 2020.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Atlantic Power is an independent
power producer that owns power generation assets in eleven states in the United States and two provinces in Canada. The
Company&#8217;s generation projects sell electricity and steam to investment-grade utilities and other creditworthy large
customers predominantly under long&#45;term PPAs that have expiration dates ranging from 2020 to 2043. The Company seeks to
minimize its exposure to commodity prices through provisions in the contracts, fuel supply agreements and hedging
arrangements. The projects are diversified by geography, fuel type, technology, dispatch profile and offtaker (customer).
Approximately 75% of the projects in operation are 100% owned and directly operated and maintained by the Company. The
Company has expertise in operating most fuel types, including gas, hydro, and biomass, and it owns a 40% interest in one coal
project.</P>
