Newton, Massachusetts-based First Wind, announced the start of commercial operations for its Stetson Wind project in Washington County, Maine.
The 57-megawatt (MW) project is the largest wind farm in New England and will have the capacity to power about 23,500 homes.
The wind farm consists of 38 General Electric (NYSE: GE) 1.5-MW wind turbines, and will have the capacity to generate approximately 167 million kilowatt-hours (kWh) of electricity every year.
Construction on the project began in January 2008, and First Wind spent about $50 million with Maine-based businesses developing the project.
First Wind said it plans to build additional projects in Maine, including a proposed 25.5 MW expansion at Stetson Wind, as well as the 60 MW Rollins Wind project near the town of Lincoln. First Wind has submitted permit applications with state agencies for both projects.
