Site description

Alliant Energy Corporation’s Prairie Creek Generating Station is located in Linn County, IA, along the banks of the Cedar River and the head of Prairie Creek. Opened in 1951, Prairie Creek Generating Station is capable of generating 245 MW from four coal-fired units. Since 2010, Alliant Energy Corporation has closed Unit 2 (23 MW), converted Unit 4 (149 MW) to natural gas, and plans to retire Units 1 and 3 (64.6 MW total) by 2025. Prairie Creek’s Ponds 3-7, Discharge Pond, and Beneficial Use Storage Area are regulated under the CCR rule. You can find the industry-reported data here.
