The Oconee Nuclear Station is a nuclear power station located on Lake Keowee near Seneca, South Carolina, and has a power output capacity of over 2,500 megawatts. It is the second nuclear power station in the United States to have its operating license extended for an additional twenty years by the Nuclear Regulatory Commission (NRC) (the application for the Calvert Cliffs Nuclear Power Plant in Maryland preceded it).
This plant has three Babcock & Wilcox pressurized water reactors, and is operated by Duke Energy.
In April 2025 all three units have received licenses to operate 80 years (1st until February 2053, 2nd until October 2053, 3rd until July 2054).
