This is a list of electricity-generating power stations in the U.S. state of South Dakota. In 2021, South Dakota had a total summer capacity of 4,169 MW through all of its power plants, and a net generation of 18,827 GWh.^[2] The corresponding electrical energy generation in 2022 was 54.8% wind, 29.2% hydroelectric, 10% coal and 5.7% natural gas.^[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]

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 & 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]
