Maine at a glance
Maine combines high winter heating demand with constrained regional transmission, a costly pairing. Retail supplier choice is available, so contracted rates vary. Heat pump adoption here is among the highest in the country, which is shifting the winter load profile: households that once burned oil now draw electricity through the coldest months, when New England generation costs peak.
