Catawba

Catawba Nuclear Station is located on Lake Wylie in York County, South Carolina, on the southwestern portion of the lake, which is the oldest lake on the Catawba River and supplies cooling water to the plant. The station began operations with two pressurized water reactors—Unit 1 in 1985 and Unit 2 in 1986.
The plant is jointly owned by North Carolina Municipal Power Agency No. 1, North Carolina Electric Membership Corporation, Piedmont Municipal Power Agency, and Duke Energy, which operates the site. It has a total generating capacity of 2,310 megawatts, enough to power approximately 1 to 1.7 million homes, making it one of the largest nuclear plants in Duke Energy’s fleet.
Originally licensed for 40 years, Catawba received a 20-year license extension from the Nuclear Regulatory Commission. South Carolina is the third largest generator of nuclear electricity. The pair of light water reactors at the Catawba plant are the largest in the State (although, with three reactors, the Oconee plant has the most nuclear capacity in the southeastern United States). Catawba is located on a 391-acre peninsula.
