NuclearSouth CarolinaUnited States of America

V C Summer is a 1,006 MW nuclear power station in South Carolina, United States of America. It is operated by Dominion Energy South Carolina Inc. Based on reported annual generation of 8,248 GWh, it can supply roughly 2.4 million homes. It ranks #597 of 10,884 United States of America power plants by installed capacity. Commissioned in 1984, it is around 42 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 17.4% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

In context: how this plant compares

At 1,006 MW, V C Summer is below the median nuclear plant in United States of America (1,350 MW). Nuclear plants split uranium to raise steam with no direct CO₂; they run as steady baseload with very high capacity factors and the longest operating lifetimes of any thermal plant.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 34.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 41% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 33/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
