Duke Energy announced that its nuclear fleet achieved a record capacity factor of 96.9% in 2025, marking the highest systemwide reliability level for the company’s nuclear plants. This performance contributed to about $600 million in federal nuclear production tax credits, which are being passed on to customers to help reduce their energy costs.
The company operates 11 nuclear units at six locations across North and South Carolina, making nuclear power its largest generation source in the region. Duke Energy’s nuclear plants provide electricity to more than 8 million homes with consistent, around-the-clock service.
Kelvin Henderson, chief nuclear officer for Duke Energy, stated: “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.”
Looking ahead, Duke Energy plans to extend the operational lifespan of its reactors, conduct power uprates to increase output from existing infrastructure, and pursue advanced reactor development. The company says these strategies will help maintain dependable and low-cost power while meeting rising energy demands in the Carolinas.
Duke Energy is one of America’s largest energy holding companies. Headquartered in Charlotte, North Carolina, it serves 8.6 million electric customers across six states and owns over 55,000 megawatts of energy capacity.
