Central Maine Power covers most of the cities we've sampled. Portland, Lewiston, South Portland, Auburn and Biddeford all run on it, in a deregulated market where you can shop for your own supplier. Bangor is the exception, served by Bangor Hydro instead. Your address decides both which utility delivers your power and whether shopping for a plan is on the table.

Central Maine Power delivered electricity at sampled addresses across Portland, Lewiston, South Portland, Auburn and Biddeford. The state's largest population centers, mostly clustered in southern Maine. Bangor, further north and east, runs on Bangor Hydro instead, a separate utility with its own territory.
Every city we've sampled except Bangor is flagged as a deregulated retail market. Central Maine Power owns the wires and keeps the lights on either way, but you're free to shop for a competing electricity supplier in those cities. Gas and water coverage isn't consistently confident yet in our sampling for these cities, so those accounts are worth confirming individually at the address level.
