BOSTON, MASSACHUSETTS--(CCNMatthews - March 31, 2006) -

2005 Highlights:

- Sold MASSPOWER asset and contracts for significant contribution to cash flow

- Increased ownership at Gregory project

- Executed accretive new Power Purchase Agreements at two existing projects

- Enhanced operating performance and cash flow at existing facilities

Atlantic Power Corporation (TSX:ATP.UN) (the "Company") today announced its results for the three months and year ended December 31, 2005. All amounts are in US dollars unless otherwise indicated.

"We were very pleased with our operating and financial results in 2005 as we delivered on all of our stated growth strategies and objectives," commented Barry Welch, President and CEO. "With this strong performance, we implemented our first increase in monthly cash distributions during the year."

Chambers Acquisition

In September the Company completed the acquisition of a 40% interest in a 262 MW coal-fired cogeneration facility located at E.I. DuPont de Nemours & Company's Chambers Works complex in southwestern New Jersey. The cash purchase price of approximately $65.0 million was funded by cash on hand and a draw on the revolving credit facility. The acquisition diversified the portfolio's fuel mix, increased its off taker diversity, lengthened the weighted average term of its power purchase portfolio and increased the Company's aggregate net interests of power generating capacity. The acquisition was also immediately accretive to the Company's cash flow.

With the completion of the Chambers acquisition, the Company increased annualized cash distributions by Cdn $0.03 per Income Participating Security ("IPS") to Cdn $1.03 per year effective with the September 2005 payment.

Masspower Disposition

On December 28, 2005 the Company sold its 17.5% interest in the 267 MW Masspower project following the buyout of three of the project's four power purchase agreements ("PPAs") and subsequent disposition of its fuel contracts during 2005. The Company's share of the total distributions generated from operations, PPA restructuring, fuel contract disposals and sale of the facility in 2005 totaled approximately $62,2 million. The disposition proceeds of approximately $59.4 million exceeded the net present value of future cash flows projected at the time of the IPO by over $20 million, and were successfully redeployed to complete the accretive Chambers acquisition.

Improved Operating Margins and PPA Extensions

During 2005, the Company generated improved operating margins at a number of facilities, and increased its indirect ownership interest at the Gregory project to 17.1% from 9.4%.

During 2005 new power purchase agreements (PPAs) were executed at the Gregory and Rumford projects. Earlier projections had anticipated no distributions in 2006 and beyond for the Rumford project, the Company now expects approximately $4 to 6 million in 2006 and is working with the project's other partners to lock in profits over a longer period. At the Gregory facility a new PPA with a better credit quality customer was negotiated through 2008 to replace a contract that expired in 2005. As a result, the previously anticipated economics of the project through 2008 will be significantly improved.

"These transactions are excellent examples of how we are proactively managing our PPA expirations and adding incremental cash flow by leveraging our solid asset base and significant experience in the industry for the benefit of our investors," Mr. Welch added.

Strong Performance in 2005

Cash Flow Available for Distribution for the year ended December 31, 2005 was $46.7 million or Cdn $1.46 per IPS. Distributions declared for the year were $32.5 million or Cdn $1.01 per IPS. The payout ratio was 66.7% in 2005.

The Company generated project revenue of $184.7 million and project income of $48.3 million for the year. The net loss for the twelve months ended December 31, 2005 was $0.5 million or $0.01 (Cdn $0.01) per IPS.

Earnings before interest, taxes, depreciation and amortization ("EBITDA") at the Company's power producing projects increased 20% in 2005 compared to the prior year, excluding MASSPOWER and the deferred revenue adjustment at Mid-Georgia. The increase in EBITDA is primarily due to favorable impacts from improved operating margins at the Lake, Orlando, and Pasco projects, increased ownership in the Gregory project combined with it's new PPA that benefits from high gas costs, and almost four months of ownership in Chambers, offset by higher fuel costs at Selkirk slightly above the amount that can be passed through to the customer, and as expected, lower-scheduled swap settlement payments received at Onondaga.

Solid Fourth Quarter Results

For the three months ended December 31, 2005, Cash Flow Available for Distribution was $20.6 million (Cdn $0.54 per IPS). Distributions declared in the quarter were $9.8 million (Cdn $0.26 per IPS), resulting in a payout ratio of 47.3%. The Company generated project revenue of $58.0 million and project income of $7.7 million in the fourth quarter of 2005. The net loss for the three months ended December 31, 2005 was $2.7 million or $0.06 (Cdn $0.07) per IPS.

The fourth quarter calculation of cash flow available for distribution benefited from adding back the $5,519 finalized estimate of tax payable on the MASSPOWER disposal, which was not added back in the calculation for prior interim periods of 2005.

EBITDA at the Projects increased 24% in the quarter compared to the year earlier period, excluding MASSPOWER and the deferred revenue adjustment at Mid-Georgia. The increase is primarily due to improved operating margins at the Lake, Orlando and Pasco projects, the increased ownership in the Gregory project combined with its new PPA, and a full quarter of ownership in the Chambers project, partially offset by lower scheduled swap settlements at Onondaga and the effect of fuel cost pass through limitations at Selkirk as discussed above. "We were pleased with our results in 2005, and anticipate continuing solid and stable performance going forward," Mr. Welch concluded.

Mark Byskov, Atlantic's CFO, has informed the Company that for personal reasons he will be leaving his CFO position. The Company has hired an executive recruiting firm to retain a CFO. Mr. Byskov has committed to remain in the position through June 30, 2006 to help affect an orderly transition. "Mark has done a tremendous job of building our financial reporting infrastructure and I respect his decision to rejoin his family in Toronto", said Mr. Welch

1) In previous quarters, MASSPOWER's distributions in respect of
   disposal proceeds were included in Cash flows from operating
   activities and separately netted out of Cash flow available for
   distribution. Those proceeds now appear as a disposal in the
   financing activities section of the statement of cash flows.

2) Represents the portion of income tax withholding installments paid
   during the quarter related to operating activities which are
   anticipated to be recoverable by the Company.

3) In the second and third quarters estimated tax payments of $5,281
   on MASSPOWER disposals were not added back in the calculation of
   cash flow available for distribution. This fourth quarter
   calculation benefits from adding back the entire $5,519 finalized
   estimate of tax payable on the MASSPOWER disposal.
