About McGuire

McGuire Nuclear Station is located on Lake Norman in Mecklenburg County, North Carolina. Lake Norman—the state’s largest man-made lake—was built by Duke Energy in 1963 by damming the Catawba River with Cowans Ford Hydroelectric Station. The lake provides cooling water for both McGuire and Marshall Steam Station.

McGuire was the second of three nuclear stations designed and built by Duke Energy. Unit 1 began commercial operation in 1981, followed by unit 2 in 1984. Today, Duke Energy’s nuclear fleet provides electricity to approximately half of its customers in the Carolinas.
