Pattern Energy Group LP (“Pattern Development”) announced it has acquired from SunEdison the development rights to the proposed 600 megawatt (MW) King Pine Wind power project. “We are excited about the opportunity to expand our previous activities in Maine by taking over development of the state’s largest wind power project,” said Mike Garland, President and CEO of Pattern Development. “Maine is an extraordinary place and we have been working for years to find a great project that can be developed in a manner that is respectful of the local community and the environment. The King Pine project would establish a strong new source of revenue for the local community and the state, create new jobs and provide clean energy.” King Pine Wind is a 600 MW wind power project currently under development in northeastern Maine, located in Aroostook and Penobscot Counties. The project will utilize 174 turbines and will interconnect to the ISO New England at Emera Maine’s proposed 345 kV Hammond substation. King Pine Wind is expected to begin full construction in 2018 and reach commercial operation in 2020. Pattern Energy Group Inc. (NASDAQ: PEGI) (TSX: PEG) holds a right of first offer with respect to any power project that Pattern Development decides to sell, including the King Pine Wind project.
