Regional energy interests are making a move to break up an electricity logjam that has stalled wind power development in Maine.
Over the last decade, Maine wind developers have built new turbines at a rapid clip, bringing overall capacity to more than 900 megawatts by last December. Maine now produces some 60 percent of the wind energy in New England — enough to power more than 150,000 homes, and developers want to build more turbines in northern and western Maine.
But in 2017, ISO New England, which administers New England’s power grid, hasn’t permitted any new wind proposal in Maine. Al McBride, the group’s transmission planning director, says the trunk power lines in Maine were built mainly to serve local loads — and they have reached their capacity.
