EIA averages, data through 06/2026. All-in means supply and delivery together; supplier contract quotes cover the supply portion only, so the two are not directly comparable.

Maine commercial electricity at a glance

The average Maine commercial account paid 22.24¢ per kWh all-in, supply and delivery together, versus 14.19¢ nationally (EIA, 06/2026), and used about 2,998 kWh a month (EIA, through 2026). That average mixes corner stores with hospitals, so it is market context rather than a quote for any one business, and supplier contract quotes cover the supply portion only, so the two figures are not directly comparable. Among the 14 states with retail electricity choice, Maine has the 10th lowest all-in commercial average. The regulator is the Maine Public Utilities Commission.

How retail electricity choice works in Maine

Maine's retail choice covers the territories of Central Maine Power and Versant Power, which keep delivering the electricity whichever supplier a business chooses. A business can buy supply from a competitive electricity provider approved by the Maine PUC, or take the standard offer service the PUC arranges for each utility through a periodic bid. Brokers and aggregators are approved by the Maine PUC under the same chapter as suppliers before they may operate.
