A plan to put 33 wind turbines on forested ridgelines in Coos County has won unanimous approval from the state Site Evaluation Committee. Granite Reliable Power's plan calls for turbines on peaks in Millsfield and Dixville and a substation in Dummer. The wind farm would connect to a transmission line known as the Coos County loop and produce 99 megawatts of electricity, making it the largest in the state. The $257 million project still needs approval from the federal Army Corps of Engineers, the Federal Aviation Administration and ISO New England.
