Introduction Nuclear Power

Duke Energy operates seven nuclear units in the Carolinas — three at Oconee Nuclear Station in Oconee County, S.C., two at Catawba Nuclear Station in York County, S.C., and two at McGuire Nuclear Station in Mecklenburg County, N.C. Nuclear power provides about half of the electricity used by our customers in the Carolinas.

Safety and security are the highest priority in Duke Energy’s nuclear program. Our plants are designed, built and operated for safety, with multiple barriers and redundant and diverse safety systems to protect the public, plant workers and the environment.

The cost of generating electricity with nuclear power is stable and economical. Among coal, natural gas and oil, nuclear power plants have had the lowest electricity production costs since 2001.

In late 1967, Duke Energy began construction of Oconee Nuclear Station, its first commercial nuclear facility. Oconee began operation in 1973. At full capacity, Oconee’s three units produce more than 2,500 megawatts.

Duke Energy also operates the McGuire Nuclear Station and Catawba Nuclear Station. McGuire’s two units produce 2,200 megawatts and Catawba’s two units have a capacity of 2,258 megawatts.

Duke Energy has operated nuclear plants for more than 35 years, setting industry benchmarks for safety and efficiency. The McGuire and Oconee nuclear stations also feature an energy education center, which provide a hands-on learning experience and community events.
