This is a list of electricity-generating power stations in Idaho , sorted by type and name. In 2022, Idaho had a total summer capacity of 5,355 MW through all of its power plants, and a net generation of 16,278 GWh. [2] The electrical energy generation mix in 2023 was 43.5% hydroelectric, 32.1% natural gas, 15% wind, 5.5% solar, 2.8% biomass, 0.6% geothermal, and 0.5% other. [1]
During 2021, Idaho was one of the top-five U.S. states in 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]

Since 1951, fifty-two reactors have been built on the grounds of the Atomic Energy Commission's National Reactor Testing Station, currently the location of the U.S. Department of Energy's Idaho National Laboratory (INL). BORAX-III was the first nuclear reactor to supply electrical power to the U.S. grid in 1955. Four reactors which do not generate electricity are in operation at the site as of year 2020. [88]

Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind, the sun or hydro-electric installations. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production.
