There are a number of wind power projects in the state of Maine, totalling more than 900 MW in capacity. The largest single wind farm is the Oakfield with an installed capacity of 148 MW.
As of the end of 2016, 901 megawatts of wind generation capacity had been installed in Maine. In 2016 wind power generated nearly 14% of the state's total electricity. Former Governor John Baldacci set a goal for the state of 2,000 megawatts of wind power installed by 2015 and 3,000 MW by 2020. While the 2015 goal was not met, wind power still provides Maine with over 10 percent of its generation.
Mars Hill (46°31.26′N 67°48.82′W / 46.52100°N 67.81367°W), in the town of Mars Hill, Maine, underwent an $85 million wind turbine project in the fall of 2006, installing more than 28 GE 1.5 MW Wind Turbines along the top and northern section of the mountain, which overlooks Canada. The wind turbines are assembled in four parts. The towers, made of three support sections stacked on top of one another, and each weighing 20,000 pounds, are 262 ft (80 m) tall. The blades attached to the hub of the turbine are about 115 ft (35 m) long – giving a rotor span exceeding the wingspan of a Boeing 747 jet-liner. This is small, though, compared to the wind turbines available in 2017.
