Atlantic Power Announces New Currency Hedges

BOSTON, MASSACHUSETTS -- (MARKET WIRE) -- 10/24/08 -- Atlantic Power Corporation (TSX: ATP.UN) ("Atlantic Power" or the "Company") announced today that it has extended through 2013 its forward purchases of Canadian dollars in amounts sufficient to make the current level of monthly distributions on its Income Participating Securities ("IPS").

"We are very pleased to have extended our strategy of mitigating currency risk for another two years through 2013," commented Barry Welch, Atlantic Power President and CEO. "As a result of the recent changes in currency exchange rates, we were able to lock in approximately $21 million of additional cash flow for the 2012-13 period when compared to the one-to-one exchange rates that existed only a few months ago."

The Company executed these forward Canadian dollar purchases for 2012 and 2013 at Cdn$1.14 and Cdn$1.23, respectively, per U.S. dollar. As a result of the new currency hedges, 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 through 2015 without including additional cash flows from the pending Auburndale acquisition or any future potential acquisitions. This represents an improvement from the Company's previous projections that had indicated the current level of cash distributions to IPS holders could be made through 2014.
