This is a list of electricity-generating power stations in Idaho, sorted by type and name. In 2023, Idaho had a total summer capacity of 5,353 MW through all of its power plants, and a net generation of 17,842 GWh.[2] The electrical energy generation mix in 2024 was 44.7% hydroelectric, 31.5% natural gas, 15.4% wind, 5.5% solar, 2.2% biomass, 0.4% geothermal, and 0.4% other.[1]
During 2021, Idaho was one of the top five U.S. states with its share of renewable electricity generation. It has a rapidly growing population and many undeveloped resources. Idahoans have consumed about 50% more electricity during recent years than is generated within the state.[3]
