From Wikipedia, the free encyclopedia

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

  Wind (55.4%)
  Hydroelectric (21%)
  Natural Gas (13.9%)
  Coal (9.2%)
  Solar (0.3%)
  Biomass (0.1%)
  Petroleum (0.1%)

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

[edit]

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]
