List of power stations in South Dakota

This is a list of electricity-generating power stations in the U.S. state of South Dakota. In 2019, South Dakota had a total summer capacity of 4,169 MW through all of its power plants, and a net generation of 12,616 GWh.[2] The corresponding electrical energy generation was 18.0% coal, 8.2% natural gas (including petroleum), 54.6% hydroelectric and 19.2% wind. Other renewable and recovery sources contributed just 3 GWh of generation, primarily from utility- and small-scale solar photovoltaic facilities.[1]

Sources of South Dakota electricity generation:
full-year 2019 [1]

  Coal (18.0%)
  Natural Gas (8.2%)
  Hydroelectric (54.6%)
  Wind (19.2%)

During 2019, 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 in-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 & gas in 1968, and ultimately retired in the early 2000's. 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]
