Atlantic Power owns and operates a diverse fleet of power generation and infrastructure assets in the United States and Canada. The Company’s power generation projects sell electricity to utilities and other large commercial customers largely under long-term PPAs, 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 3,366 MW in which our aggregate ownership interest is approximately 2,117 MW. These totals exclude projects designated as held for sale at December 31, 2012 and our 40% interest in Delta-Person for which the Company entered into an agreement to sell in December 2012. On January 30, 2013, the Company and certain of its subsidiaries entered into an agreement to sell our interests in the Auburndale, Lake and Pasco projects. The Company expects to enter into a purchase and sale agreement in the remaining part of the first quarter to sell its 100% interest in its Path 15 project. Its current portfolio of continuing operations consists of interests in twenty-nine operational power generation projects across eleven states in the United States and two provinces in Canada. In addition, the Company has one 53 MW biomass project under construction in Georgia. Recently the Company acquired a wind and solar development company, Ridgeline, located in Seattle, Washington, which will enhance its ability to develop, construct, and operate wind and solar energy projects across the United States and Canada. The Company also owns a majority interest in Rollcast Energy, a biomass power plant developer in North Carolina.
