This is a list of electricity-generating power stations in the U.S. state of Maine, sorted by type and name. In 2021, Maine had a total summer capacity of 5,026 MW through all of its power plants, and a net generation of 10,908 GWh.^[2] The electrical energy generation mix in 2022 was 31.6% natural gas, 23.5% wind, 19.5% hydroelectric, 16% biomass, 4.4% solar, 2.3% petroleum, 0.4% coal, and 2.4% other. Small-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 336 GWh of energy to the state's electrical grid. This was equivalent to about two thirds of the amount generated by Maine's utility-scale photovoltaic plants.^[1]

During 2021, renewable sources generated 74% of all electrical energy from Maine, making it one of the top-five U.S. states. Maine's share of wind generation is the largest among New England states, and its share of biomass generation from the wood industry and municipal waste sources is the largest in the United States. Maine's electricity generation has not met the in-state demand in recent years, and about one-quarter of its electricity consumption was imported from Canada.^[3]

Nuclear power stations

The Maine Yankee Nuclear Power Plant generated 860 MW of base load electricity during years 1972–1996. Decommissioning was completed in 2005.^[4][5] Maine had no utility-scale plants that used fissile material as a fuel in 2019.^[1]
