Who owns Maine's electric companies

Electric utilities in Maine by ownership type

Investor-owned utility2722,30196.8%
Municipal utility313,0771.8%
Electric cooperative110,8081.4%

Each type is run differently. An investor-owned company answers to shareholders and a state commission. A municipal utility answers to a city. A cooperative answers to its members. That is why the same state can have very different prices and service from one address to the next.

Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data). Customer-weighted average of the prices utilities report for bundled residential service. It leaves out delivery-only customers and retail providers.

Outside the investor-owned companies, the largest municipal utility is Kennebunk Light and Power District (6,723 homes), and the largest electric cooperative is Eastern Maine Electric Cooperative (10,808 homes).

Price differences between types come from costs, customer density and the way each type is financed, so a lower average does not decide which is better for your home.
