List of power stations in South Dakota

Sources of South Dakota utility-scale electricity generation,
full-year 2023: ^[1]

1. Wind (55.4%)
2. Hydroelectric (21%)
3. Natural gas (13.9%)
4. Coal (9.2%)
5. Solar (0.3%)
6. Biomass (0.1%)
7. Petroleum (0.1%)
8. 0.00%

This is a list of electricity-generating power stations in the U.S. state of South Dakota . In 2022, South Dakota had a total summer capacity of 6,324 MW through all of its power plants, and a net generation of 17,900 GWh. ^[2] In 2023, the electrical energy generation mix was 55.4% wind, 21% hydroelectric, 13.9% natural gas, 9.2% coal, 0.3% solar, 0.1% biomass, and 0.1% petroleum. ^[1]

During 2021, South Dakota was among the top U.S. states in its share of renewable electricity generation. It was also among the top states in per-capita consumption. In recent years, more electricity was consumed than was produced and wind generation has been expanding rapidly in the state. ^[3]

Nuclear power stations

The Pathfinder Nuclear Generating Station was an early commercial and demonstration plant near Sioux Falls that generated up to 59 MW of grid-connected electricity for brief periods during years 1966–1967. ^[4] The single BWR reactor was decommissioned in 1967, the facility converted to use oil and gas in 1968, and ultimately retired in the early 2000s. The reactor and other nuclear components were removed in 1990. ^[5] South Dakota had no utility-scale plants that used fissile material as a fuel in 2019. ^[1]
