This is a list of electricity-generating power stations in the U.S. state of Maine, sorted by type and name. In 2020, Maine had a total summer capacity of 4,875 MW through all of its power plants, and a net generation of 10,002 GWh. The corresponding electrical energy generation mix in 2021 was 27.1% hydroelectric, 24.7% natural gas, 23.3% wind, 19.9% biomass, 2.4% non-biogenic waste, 1.6% solar, 0.6% coal, and 0.4% petroleum. Small-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 136 GWh of energy to the state's electrical grid. This was about equal to the amount generated by Maine's utility-scale photovoltaic plants.
