Oconee Nuclear Station
- Capacity: 2,538 megawatts
- Location: Oconee County, S.C.
- Commercial Date: 1973
Oconee Nuclear Station is located on Lake Keowee in Oconee County, S.C., eight miles north of Seneca, S.C. Unit 1 began commercial operation in 1973, followed by units 2 and 3 in 1974.
Since it began operating, Oconee has safely and reliably generated more than 500 million megawatt-hours of electricity — the first nuclear station in the United States to achieve this milestone. Oconee is one of the nation’s largest nuclear plants with a generating capacity of approximately 2.6 million kilowatts. This is enough electricity to power 1.9 million homes.
Oconee earned the further distinction of being the second nuclear station in the country to have its licenses renewed by the Nuclear Regulatory Commission (NRC) for an additional 20 years. All U.S. reactors are initially licensed by the NRC for 40 years.
Duke Energy nuclear power plants operate at a very high level of security every day. Oconee was designed and built with redundant safety systems and multiple barriers to protect the public, plant workers and the environment.
