Wind power generated in Maine is now producing nearly 500 megawatts, enough to supply the average needs of 175,000 households. However, it's still well short of the state's goal for wind generation by 2015.
But new projects that are in conceptual stages, under regulatory review or approved but facing challenges could catapult the state to half of its wind-power goal of 2,000 megawatts by 2015. The Legislature has set that goal for installed wind power capacity, along with 3,000 megawatts by 2020.
Maine's operating wind power plants have a capacity to produce 468 megawatts online now, according to figures from the state Department of Environmental Protection, which regulates grid-scale projects in Maine's Unorganized Territory.
