CMP shares northern Maine transmission route with legislators

BANGOR DAILY NEWS • October 10, 2026

The Maine Republican Caucus got the first look this week at a proposed transmission line route designed to move electricity from Aroostook County to the New England grid. The Central Maine Power/Avangrid 1,200-megawatt transmission line, connecting northern Maine to the regional grid through substations in Haynesville and Pittsfield, is part of the planned Northern Maine Renewable Energy Development Program. The 108-mile route already has some Mainers concerned about how it will affect their homes, farms, and northern Maine’s abundant wildlife and wilderness. The discussion with legislators was one of many that will take place over the coming weeks and months as engineering, environmental review, permitting and other planning activities move forward, CMP officials said.
