Atlantic Power Corporation Announces Fourth Quarter and Year End 2008 Results

TORONTO, ONTARIO, Mar 30 (MARKET WIRE) --
Atlantic Power Corporation (TSX: ATP.UN)(TSX: ATP.DB) (the "Company")
today announced strong results for the three months and year ended
December 31, 2008. All amounts are in U.S. dollars unless otherwise
indicated.

2008 Highlights:

- Cash available for distribution up 29%, including one-time items

- Accretive acquisition in fourth quarter to generate positive
contribution

- Increased cash distributions by 3.2% to annualized Cdn$1.094 per IPS in
fourth quarter

- Extended currency hedge on cash distributions two years through
December 2013

- Management reiterates its previous guidance regarding sustainability of
distributions

"We continue to generate solid operating results, while the acquisition
of Auburndale in the fourth quarter will make significant contributions
to our cash flow going forward," commented Barry Welch, President and
CEO. "We were very pleased to have increased cash distributions again in
2008, the third increase in the last four years."

Operating Performance

Adjusted EBITDA at the Projects, including earnings from equity
investments, increased by $2.9 million or 7% for the quarter ended
December 31, 2008 compared to the same period last year. Adjusted EBITDA
in the fourth quarter was affected by a number of factors, including:

- The acquisition of the Auburndale project in November 2008.

- The receipt of a partial settlement of business interruption insurance
claims at Orlando related to the unplanned outage earlier in the year.

- The absence of revenue at Onondaga as the plant was shut down in the
second quarter of 2008.

- The delay in timing of distributions from Selkirk as a result of
restrictions required under the terms of the Project's non-recourse debt
due to a coverage test that was subsequently passed in December.

For the year ended December 31, 2008, Adjusted EBITDA increased
approximately $1.8 million or 1% compared to 2007. In addition to the
factors described above for the fourth quarter, Adjusted EBITDA was
affected by the following factors:

- The receipt of an $8.2 million distribution in the first quarter of
2008 from the Gregory Project resulting from a release of debt services
reserve.

- Increased Adjusted EBITDA at the Lake project in 2008 due to higher
power prices and higher plant efficiency as a result of the turbine
upgrades performed in the fourth quarter of 2007.

- Higher Adjusted EBITDA at Pasco due to the acquisition of the
additional interest in the Project in December 2007 and higher power
prices, partially offset by higher fuel costs as a result of market price
purchases following the expiration of its fuel supply agreement on June
30, 2008. Beginning January 1, 2009, a new ten-year PPA at the Pasco
Project requires the PPA counterparty to provide natural gas required to
operate the plant so the Project will no longer be exposed to changes in
market prices of natural gas.

Cash Flow Available for Distribution

For the three months ended December 31, 2008, Cash Flow Available for
Distribution declined to $37.2 million compared to $42.3 million for the
same period last year. The decrease is due primarily to a larger income
tax refund in the 2007 fourth quarter, partially offset by the release of
debt service reserves at Pasco in the fourth quarter of 2008 as a result
of the final payment of the Project's debt. In addition, the working
capital change in the fourth quarter of 2007 was positively impacted by a
timing difference in the receipt of revenues at the Lake and Orlando
Projects. Distributions declared in the fourth quarter of 2008 were $13.4
million, resulting in a payout ratio of 36% compared to a payout ratio of
39% in last year's fourth quarter.

For the year ended December 31, 2008, Cash Flow Available for
Distribution rose to $103.7 million compared to $80.1 million for the
same period last year. The increase is attributable to higher operating
cash flow in 2008, which reflects higher Project Adjusted EBITDA and the
positive impact of certain non-recurring cash flows in 2008. The most
significant of the non-recurring cash flow items in 2008 were the release
of debt service reserves at Pasco and the reduced working capital
investment at Onondaga associated with the shut-down of that facility.
See Recent Developments below for additional details about redevelopment
efforts at Onondaga. Distributions declared for 2008 were $61.3 million,
resulting in a payout ratio of 59% compared to 77% in the prior year.

Recent Developments

The Federal Energy Regulatory Commission (FERC) issued its initial order
regarding Path 15's 2008-2010 rates on February 19, 2008. That order
granted approval of the Company's proposed 13.5% return on equity and set
certain other matters for hearing. On March 23, 2009, Path 15, FERC
staff, and the intervenors in the Project's rate case filed an
uncontested settlement with the FERC. The terms of the settlement will
allow Path 15 to make distributions to the Company that are consistent
with management's expectations in 2009 and 2010. The Company expects the
FERC to approve the settlement in the next 2-3 months. Once it is
approved, Path 15 will be making a refund of approximately $1.3 million,
comprising the amount collected above the settlement rates since the
initial order in February, 2008. Independently, the final resolution of
pending landowner litigation over right-of-way issues was resolved
recently, which will result in approximately $6 million being released in
the second quarter to Path 15 from a construction reserve account.

During the fourth quarter, management reviewed the recoverability of its
investment in the Stockton project. The review was undertaken as a result
of the current and long-term market conditions for coal-fired generation
assets in California, including the price of natural gas which sets
marginal electricity prices. Based on this review, management determined
that the Stockton project was impaired and recorded a pre-tax impairment
of $18.4 million, which represents the entire carrying value of the
project's property, plant and equipment at December 31, 2008. The 50MW
project, in which the Company has a 50% interest, has contributed an
average of only about 2% of project distributions over the past few
years. The Company is considering a variety of options to recover some of
its investment in the Stockton project.

On November 21, 2008, the Company acquired Auburndale Power Partners,
Limited Partnership ("Auburndale"), which owns and operates a 155 MW
natural gas-fired combined cycle cogeneration facility located in Polk
County, Florida. The purchase price was approximately $140 million and
was funded by cash on hand, a borrowing under the Company's credit
facility and $35 million of non-recourse acquisition debt. Auburndale is
the last of the projects in which the Company was granted a right of
first offer by ArcLight Energy Partners Fund I, L.P. at the time of the
Company's initial public offering.

On July 25, 2008, the Toronto Stock Exchange ("TSX") approved a normal
course issuer bid to purchase up to four million IPSs, representing
approximately 8% of the Company's public float. As of December 31, 2008,
the Company had acquired and cancelled 558,620 IPSs at an average price
of Cdn$8.78 under the terms of the issuer bid.

As previously disclosed since the Company's IPO, the Onondaga Project was
formally taken offline on April 30, 2008, although payments continued
under the Project's swap and indexed hedge agreements through June. The
Project has sold gas turbines, spare parts and other equipment no longer
being used, with proceeds from the sales of $7.5 million received during
the year. The Company is continuing its efforts with an experienced
developer to redevelop the site into a 35-40 MW biomass plant and has
contributed certain remaining assets of the Onondaga Project to the new
joint venture.

Guidance

As of the date of this release, the Company reiterates its previous
guidance that based on management projections, the Company's cash on hand
and projected future cash flows from existing Projects are sufficient to
meet the current level of cash distributions to IPS holders into 2015
before considering any positive impact from potential acquisitions or
organic growth opportunities.

Based on year-to-date results and management projections for the
remainder of the year, the Company expects to receive distributions from
its Projects in the range of $90 million to $95 million for the full year
2009. This amount represents a decrease of approximately $30 million to
$35 million over distributions received from the Projects in 2008 and is
partially attributable to non-recurring positive cash flows in 2008 and
anticipated changes to contractual cash flows as more fully described in
the Company's management's discussion and analysis for the year ended
December 31, 2008. A decrease in 2009 Project distributions has
historically been included in management's long-term cash flow
projections and does not change the Company's ability to continue paying
distributions to shareholders at current levels.

The calculation of Cash Flow Available for Distribution and a summary of
Adjusted EBITDA by individual project for the three months and year ended
December 31, 2008 are attached to this news release.

The Company's financial statements for the period and management's
discussion and analysis for the three months and year ended December 31,
2008 are available on the Company's website at
www.atlanticpowercorporation.com and on SEDAR at www.sedar.com.

Atlantic Power Corporation owns interests in a diversified portfolio of
14 power generation projects and one transmission line located in major
markets in the United States. Atlantic Power's objectives are to sustain
and grow its cash distributions over the long term by enhancing the
performance of its existing assets and by making accretive acquisitions.
Certain statements in this news release may constitute "forward-looking
statements", which reflect the expectations of Atlantic Power Management,
LLC (the "Manager") regarding future growth, results of operations,
performance and business prospects and opportunities of Atlantic Power
Corporation (the "Company"), and the Projects (as defined below).
Examples of such statements include the expectation that the Company's
cash on hand and projected future cash flows will be adequate to meet the
current level of cash distributions to IPS holders into 2015 and the
amount of distributions expected to be received from the Projects for the
full year 2009. Such forward-looking statements reflect current
expectations regarding future events and operating performance and speak
only as of the date of this news release. Forward-looking statements
involve significant risks and uncertainties, should not be read as
guarantees of future performance or results, and will not necessarily be
accurate indications of whether or not or the times at or by which such
performance or results will be achieved. A number of factors could cause
actual results to differ materially from the results discussed in the
forward-looking statements, including, but not limited to, the factors
discussed under "Risk Factors" section in the Company's management's
discussion and analysis for the year ended December 31, 2008 and under
"Risk Factors" in the Company's annual information form dated March 30,
2009. Although the forward-looking statements contained in this news
release are based upon what are believed to be reasonable assumptions,
investors cannot be assured that actual results will be consistent with
these forward-looking statements, and the differences may be material.
These forward-looking statements are made as of the date of this news
release and, except as expressly required by applicable law, the Company
assumes no obligation to update or revise them to reflect new events or
circumstances.

Cash Flow Available for Distribution is not a measure recognized under
Canadian generally accepted accounting principles ("GAAP") and does not
have a standardized meaning prescribed by GAAP. Management believes Cash
Flow Available for Distributions is a relevant supplemental measure of
the Company's ability to earn and distribute cash returns to investors. A
reconciliation of Cash Flows from Operating Activities to Cash Flow
Available for Distributions is attached to this news release and is also
included in the Company's management's discussion and analysis for the
year ended December 31, 2008. Investors are cautioned that the Company
may calculate this measure in a manner that is different from other
companies.

Adjusted EBITDA, earnings before interest, taxes, depreciation and
amortization (including non-cash impairment charges), is not a measure
recognized under GAAP and is therefore unlikely to be comparable to
similar measures presented by other issuers and does not have a
standardized meaning prescribed by GAAP. Management uses Adjusted EBITDA
at the Project-level to provide comparative information about Project
performance. Investors are cautioned that the Company may calculate this
measure in a manner that is different from other issuers.

1 Amounts previously reported in 2007 have been revised to conform to the
calculation of Cash Available for Distribution adopted in 2008, which does
not include any adjustment for income taxes recoverable. Through the end
of 2007, the Company was required to pay tax instalments based on
estimates of taxable income without the benefit of the interest deduction
related to the Subordinated Notes and Debentures. This requirement
resulted in the payment of significant tax instalments to the IRS,
followed by a refund of most of the instalment payments when the actual
tax returns were filed in subsequent periods with the full benefit of the
interest deductions on the Subordinated Notes and Debentures. As of
January 1, 2008, the Company is permitted to calculate tax instalment
payments with the full benefit of these interest payments factored into
estimated taxable income. As a result, management expects significant
fluctuations in working capital related to tax instalments and subsequent
refunds to decrease and the adjustment to Cash Flow Available for
Distribution is no longer needed.

2 Cash Flow Available for Distribution 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 issuers. See "Non-GAAP Financial Measures".
