Atlantic Power owns and operates a diverse fleet of power generation assets in the United States and Canada. Atlantic Power’s power generation projects sell electricity to utilities and other large commercial customers largely under long-term power purchase agreements, which seek to minimize exposure to changes in commodity prices. Its power generation projects in operation have an aggregate gross electric generation capacity of approximately 2,945 MW in which its aggregate ownership interest is approximately 2,024 MW. These totals exclude the Company’s 40% interest in the Delta-Person generating station that the Company entered into an agreement to sell in December 2012. Its current portfolio consists of interests in twenty-eight operational power generation projects across eleven states in the United States and two provinces in Canada.
