Duke Energy announced that its nuclear fleet achieved a new record for reliability in 2025, reaching a systemwide capacity factor of 96.9%. This means the company’s nuclear plants were generating power nearly all the time throughout the year. The consistent performance of these facilities supported electricity needs across North and South Carolina, serving more than 8 million homes.
The strong output from Duke Energy’s nuclear units resulted in approximately $600 million in federal nuclear production tax credits. These savings are passed directly to customers, helping to reduce their energy costs.
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 operates 11 nuclear units at six sites across the Carolinas. The plants include Brunswick Nuclear Plant in Southport, Harris Nuclear Plant in New Hill, McGuire Nuclear Station in Huntersville, Catawba Nuclear Station in York, Oconee Nuclear Station in Seneca, and Robinson Nuclear Plant in Hartsville.
Looking ahead, Duke Energy plans to extend the operational lifespan of its existing reactors, pursue power uprates to increase capacity from current infrastructure, and explore advanced reactor development. These efforts aim to ensure reliable and affordable power as energy demands grow in the region.
Duke Energy is based in Charlotte, North Carolina. The company serves electric customers across six states and owns over 55,000 megawatts of energy capacity. Its natural gas utilities serve 1.7 million customers across five states.
