Who provides Maine's plans
Every plan here comes from Central Maine Power Co — a limit of what has been indexed, not a claim that it is the only provider in Maine. How each of its plans is built, and what changing between them saves, is set out on Central Maine Power Co's own page.
What the Maine figures do not cover
Only one utility in Maine has been indexed so far, so the ranges above are not statewide. A household served by another provider will not find its plans here yet.
