List of power stations in Montana

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. 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.

In recent years three-quarters of the coal mined in Montana has been exported, with over one-third going to Asia via western Canada.

Nuclear power stations
Montana had no utility-scale plants that used fissile material as a fuel in 2022.

Fossil-fuel power stations
Data from the U.S. Energy Information Administration serves as a general reference.

Coal
A useful map of coal generation plants is provided by the Sierra Club. The Hardin facility was mostly idle and is re-ramping to service cryptocurrency mining.
