Contrary to what many people now believe, Central Maine Power’s so-called “clean energy” corridor through an undeveloped region of western Maine is NOT a done deal. The Army Corps permit is under federal appeal because they did not conduct an Environmental Impact Statement as they had for similar hydropower projects in New Hampshire and Vermont. The Department of Energy permit has not yet been granted. CMP still has municipal permits to obtain and multiple Maine towns have ordinances that would not allow the project as proposed.
The Maine Department of Environmental Protection permit is under appeal. There is also a lawsuit challenging the legality of the public lands lease that CMP obtained without the two-thirds approval of the Maine Legislature required by the Maine Constitution.
And there is now a new petition that Maine voters can sign to block the corridor (not to be confused with the earlier 2019 No CMP Corridor petition that was challenged in court by CMP).
