William H. Zimmer Power Station

The William H. Zimmer Power Station, located near Moscow, Ohio, was a 1.35-gigawatt (1, 351 MW) coal power plant. Planned by Cincinnati Gas and Electric (CG&E) (a forerunner of Duke Energy), with Columbus & Southern Ohio Electric (a forerunner of American Electric Power (AEP)) and Dayton Power & Light (DP&L) as its partners, it was originally intended to be a nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. The plant began operations in 1991. Vistra Corp. acquired ownership in 2018 and operated the plant until its closure on May 31, 2022.
