PrairieWinds, SD1, Incorporated, a subsidiary of Basin Electric, proposes to construct, own, operate, and maintain the South Dakota PrairieWinds Project, a 150-MW wind-powered generation facility, including 101 wind-turbine generators, electrical collector lines, collector substation(s), transmission line, communications system, and service access roads to access wind- turbine sites.
There are two possible locations for the proposed Project. One site is located on about 37,000 acres about 15 miles north of White Lake, South Dakota, within Brule, Aurora, and Jerauld counties, South Dakota. For this alternative, the requested interconnection is with Western’s electric transmission system at Wessington Springs Substation, located in Jerauld County, South Dakota. The other site is located on about 83,000 acres about 8 miles south of Winner, South Dakota, entirely within Tripp County, South Dakota. If this alternative is selected, the interconnection request will be with Western’s electric transmission system at Winner Substation, located in Tripp County.
Final Environmental Impact Statement available
Western and the USDA Rural Utilities Service have jointly issued a final environmental impact statement for the proposed South Dakota PrairieWinds Project and Wind Partners' proposed development.
