This is a list of electricity-generating power stations in the U.S. state of Montana, sorted by type and name. In 2022, Montana had a total summer capacity of 6,439 MW through all of its power plants, and a net generation of 27,088 GWh.[2] In 2023, the electrical energy generation mix was 44.8% coal, 29.7% hydroelectric, 17.7% wind, 3.9% natural gas, 1.9% petroleum, 0.9% solar, 0.1% biomass, and 0.9% other. Small-scale solar, including customer-owned photovoltaic panels, delivered and additional 76 GWh to the state's electrical grid in 2023.[1]
During 2019, Montana exported about one-half of the electricity generated by its power plants to other states. Montana has the largest recoverable deposits of coal in the nation, accounting for 30% of U.S. reserves. In recent years three-quarters of the coal mined in Montana has been exported, with over one-third going to Asia via western Canada.[3]
Nuclear power stations
editMontana had no utility-scale plants that used fissile material as a fuel in 2022.[1]
Fossil-fuel power stations
editData from the U.S. Energy Information Administration serves as a general reference.[4]
Coal
editA useful map[5] of coal generation plants is provided by the Sierra Club.
