More than half of the electricity generated in South Carolina came from nuclear power in 2021, the highest share among the Southeastern states that anchor the US nuclear fleet, according to data compiled by the Nuclear Energy Institute. South Carolina's 53.8 percent nuclear share reflects the state's multi unit nuclear fleet, including the Catawba, Oconee, Robinson and V.C. Summer stations.

Tennessee followed close behind at 43.4 percent, powered largely by the Tennessee Valley Authority's Sequoyah and Watts Bar plants. Alabama drew 32.2 percent of its in-state generation from nuclear power, and North Carolina drew 32.8 percent, both reflecting the Browns Ferry, Farley, Harris and McGuire units serving the region. Georgia, home to the four reactor Plant Vogtle and the two reactor Hatch plant, generated 26.8 percent of its in-state electricity from nuclear sources.

Farther west, Arkansas drew 22.5 percent of its electricity from nuclear power through Entergy's Arkansas Nuclear One plant, while Mississippi and Louisiana each drew roughly 17 percent from the Grand Gulf and River Bend stations. Texas, despite hosting two large nuclear stations at Comanche Peak and South Texas Project, drew a smaller 8.3 percent share of its far larger overall generation mix from nuclear power.

Across this nine state Southeast and South Central corridor, nuclear power consistently ranks among the top two or three generation sources, underscoring the region's reliance on the technology for steady, round the clock electricity supply as population and industrial demand continue to climb.
