Duke Energy announced that its nuclear fleet achieved a new record for reliability in 2025, operating at a systemwide capacity factor of 96.9%. This means the company’s nuclear plants were generating power nearly all year, providing steady electricity to communities across North and South Carolina.
The high level of performance resulted in approximately $600 million in federal nuclear production tax credits, which are passed directly to customers to help lower their energy bills. Duke Energy operates 11 nuclear units at six sites in the Carolinas, making nuclear its largest source of electricity generation in the region. The fleet supplies consistent power to more than eight million homes.
Kelvin Henderson, chief nuclear officer for Duke Energy, said: “This new record shows the unmatched reliability our nuclear plants deliver every day. It demonstrates the value we’re committed to providing for our customers, and it reflects the skill and dedication of the teams who operate these facilities with excellence.”
Duke Energy’s ongoing strategy involves extending the operational lifespan of its existing plants, increasing capacity through infrastructure upgrades, and exploring advanced reactor technology. These steps are aimed at ensuring reliable and affordable energy as demand grows in the Carolinas.
The company’s six sites include Brunswick Nuclear Plant (1,870 MW) in Southport, Harris Nuclear Plant (964 MW) in New Hill, McGuire Nuclear Station (2,316 MW) in Huntersville, Catawba Nuclear Station (2,310 MW) in York, Oconee Nuclear Station (2,554 MW) in Seneca, and Robinson Nuclear Plant (759 MW) in Hartsville.
Duke Energy serves about 8.6 million electric customers across several states including North Carolina and South Carolina. The company is also investing in grid upgrades and cleaner energy sources as part of its broader transition strategy.
