Atlantic Power Corporation Announces Second Quarter 2006 Results

BOSTON, MASSACHUSETTS--(CCNMatthews - Aug. 10, 2006) - Atlantic Power Corporation (TSX:ATP.UN) (the "Company") today announced its results for the three and six months ended June 30, 2006. All amounts are in US dollars unless otherwise indicated.

Highlights:

- Increase in cash available for distribution of 83% from Q2 2005

- Aggregate power generation up 29% for the quarter and 20% for year-to-date

- Acquisition of California transmission line adds regulated 30-year cash flow

- Lower payout ratio: 49% for the second quarter and 65% for year-to-date

- $10 million revolver balance from Chambers acquisition repaid

"We continue to post strong cash flow in 2006 as we maintain our focus on maximizing returns on our assets while we achieve growth through solid acquisitions," commented Barry Welch, President and CEO.

For the three months ended June 30, 2006 Cash Flow Available for Distribution was $21.1 million (Cdn $0.54 per IPS) compared to $11.6 million (Cdn $0.38 per IPS) last year. Distributions declared in the quarter were $10.3 million (Cdn $0.26 per IPS), resulting in a payout ratio of 49%, versus 64% in last year's second quarter. The $10 million borrowing on the Company's revolver from the Chambers acquisition last year was repaid during the second quarter. The Company reported project income of $16.8 million in the second quarter of 2006. Net income for the three months ended June 30, 2006 was $4.7 million or $0.11 (Cdn $0.12) per IPS.

For the six months ended June 30, 2006, Cash Flow Available for Distribution was $31.4 million (Cdn $0.81 per IPS) compared to $18.9 million (Cdn $0.62 per IPS) last year. Distributions declared in the first six months of 2006 were $20.2 million (Cdn $0.52 per IPS), and the payout ratio improved to 65%, as compared to 79% last year. The Company generated project revenue of $113.1 million and project income of $29.0 million in the first six months of 2006. Net income for the six months ended June 30, 2006 was $8.0 million or $0.18 (Cdn $0.21) per IPS.

EBITDA at the Projects increased 28% in the second quarter of 2006 compared to the prior year period. For the six months ended June 30, 2006, EBITDA at the Projects was up 15% compared to the same period in 2005. The increases were driven by the contribution in 2006 from Chambers ownership, improved operating margin at the Lake Project, and a return to normal operations at the Orlando Project following completion of its turbine upgrades during the second quarter of 2005. These positive factors were partially offset by the absence of Masspower results following its sale in the fourth quarter of 2005 and lower results from Rumford as it transitioned from the previous power purchase agreement to a market-based interim agreement.

The calculation of Cash Flow Available for Distribution and a breakdown of unaudited EBITDA by individual project for the three and six-month periods ended June 30, 2006 is attached to this news release.

"We are very pleased with our project portfolio's performance this year. Aggregate generation for the quarter was up over 29% in the period, primarily due to the contribution from the Chambers Project, and plant availability increased 3.1%," Mr. Welch commented.

Path 15 Acquisition

On June 29, 2006 the Company announced that Atlantic Power Holdings, LLC ("Holdings") had agreed to indirectly acquire 100% of Trans-Elect NTD Path 15, LLC, which owns approximately 72% of the transmission system rights in the Path 15 transmission project (the "Project" or "Path 15") located in California. Path 15 is a critical 84-mile, 500-kilovolt transmission line with strong federal and state support. It generates highly stable 30-year regulated cash flows that are independent of power prices or line utilization. The Project has very low operating risk with proven technology and a solid operating history. It will be accretive to cash flow and further enhances the diversity of the Company's project portfolio

The equity purchase price for the Project will be approximately $85.5 million and will be financed with an acquisition credit facility. There are agreed upon price adjustments in the purchase agreement to keep the Company neutral to the outcome of the two final issues still pending in the project's initial rate case with the Federal Energy Regulatory Commission (FERC). Existing debt at the Project's operating and holding companies will be assumed in the transaction but will be non-recourse to both the Company and Holdings. The acquisition is subject to approval by the FERC, which is expected in the third quarter of 2006.

"We are very pleased to be acquiring this important asset," commented Barry Welch, President and CEO. "The Project strengthens our ability to generate stable, sustainable and predictable cash flows over the long term, while enhancing the diversity and reducing the risk of our project portfolio."

The Company's financial statements for the period and management's discussion and analysis for the six months ended June 30, 2006 are available on the Company's web site at www.atlanticpowercorporation.com or on SEDAR www.sedar.com.

Atlantic Power Corporation owns interests in a diversified portfolio of 15 power generation projects located primarily in major markets in the United States. The Company'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.
