PRAIRIEWINDS SD1, a 162 MW Wind power plant in Jerauld County, South Dakota. Operated by BASIN ELECTRIC POWER COOP, commissioned 2011.
How PRAIRIEWINDS SD1 compares
With 162 MW of capacity, PRAIRIEWINDS SD1 ranks 9th among the 28 operating power plants Bywatts maps in South Dakota and 2nd of the 8 operating Wind plants in the state. It accounts for about 21% of South Dakota's operating Wind capacity and 3.8% of all operating capacity in the state. Nationally it is the 99th-largest of the 708 operating Wind plants in the database. Commissioned in 2011, it is newer than 92% of the 26 operating South Dakota plants with a recorded commissioning year. Its operator, BASIN ELECTRIC POWER COOP, runs 4 operating plants in South Dakota totaling 810 MW. It shares Jerauld County with one other operating plant, WESSINGTON SPRINGS.
EIA-860 lists 3 generators at the site with 162 MW of nameplate capacity, all onshore wind turbine technology. Net generation was 379 GWh in 2024 (a 27% capacity factor), down 1% from 2022.

Weather peril exposure
PRAIRIEWINDS SD1 is a 162 MW wind power plant in Jerauld County, SD, operated by BASIN ELECTRIC POWER COOP, commissioned in 2011. Jerauld County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.4 of 5 at the 60th national percentile. Winter weather is the leading peril, rated Relatively Low by FEMA at the 88th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a wind plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
