Davis–Besse Nuclear Power Station Davis–Besse Nuclear Power Station Davis–Besse Nuclear Power Station is a nuclear power plant northeast of Oak Harbor in Ottawa County, Ohio, United States, approximately 25 miles east of the city of Toledo. It has a single pressurized water reactor. As of 2011, it is operated by the FirstEnergy Nuclear Operating Company subsidiary of FirstEnergy Corp.
