V C SUMMER, a 1,030 MW Nuclear power plant in Fairfield County, South Carolina. Operated by SOUTH CAROLINA ELECTRIC&GAS CO, commissioned 1984.
How V C SUMMER compares
With 1,030 MW of capacity, V C SUMMER ranks 7th among the 83 operating power plants Bywatts maps in South Carolina and 3rd of the 4 operating Nuclear plants in the state. It accounts for about 15% of South Carolina's operating Nuclear capacity and 4.4% of all operating capacity in the state. Nationally it is the 46th-largest of the 55 operating Nuclear plants in the database. Commissioned in 1984, it is older than 52% of the 82 operating South Carolina plants with a recorded commissioning year. Its operator, SOUTH CAROLINA ELECTRIC&GAS CO, runs 12 operating plants in South Carolina totaling 5,236 MW. It shares Fairfield County with 2 other operating plants, FAIRFIELD PUMPED STORAGE and PARR HYDRO.
EIA-860 lists 1 generator at the site with 1,030 MW of nameplate capacity, all nuclear technology. Net generation was 7,421 GWh in 2024 (an 82% capacity factor), down 14% from 2022.
Grid neighborhood
The closest transmission line found within 10 miles is a 230 kV line, under 0.1 miles away. Another 5 operating power plants totaling 1,032 MW sit within 25 miles; the largest is FAIRFIELD PUMPED STORAGE (511 MW, Hydro).

Weather peril exposure
V C SUMMER is a 1,030 MW nuclear power plant in Fairfield County, SC, operated by SOUTH CAROLINA ELECTRIC&GAS CO, commissioned in 1984. Fairfield County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.2 of 5 at the 30th national percentile. Ice storm is the leading peril, rated Relatively High by FEMA at the 85th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a nuclear plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
