Duke Energy's Nuclear Fleet Achieves Unprecedented Reliability Record in 2025

Duke Energy's Nuclear Fleet Sets New Reliability Record



In a remarkable achievement, Duke Energy's nuclear fleet recorded an unprecedented reliability rate in 2025, confirming its critical role in providing stable energy for communities across the Carolinas. The latest figures reveal that the nuclear plants delivered power 96.9% of the time, a record-high capacity factor that underscores the operational excellence and dependability of these facilities.

This all-time record not only benefits local residents but also translates into substantial financial savings. The excellent performance of the plant enabled Duke Energy to secure around $600 million in federal nuclear production tax credits. These credits are channeled back to customers, helping to alleviate energy costs, thus directly impacting their utility bills.

Duke Energy operates a formidable fleet, consisting of 11 nuclear units spread across six different sites in the Carolinas. This fleet is pivotal for the company, as it forms the largest segment of its energy generation portfolio, catering to over eight million homes. The reliability of these plants is crucial as they contribute to stabilizing the power grid and managing system-wide costs, which is particularly vital given the increasing energy demands in the region.

Kelvin Henderson, Duke Energy's chief nuclear officer, emphasized the significance of this achievement, stating, "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."

With an eye on future expansion and sustainability, Duke Energy’s strategy includes extending the operational lifespan of its nuclear plants, implementing power uprates for increased capacity, and exploring advanced reactor technologies. These initiatives are central to the company's commitment to enhancing energy security while ensuring uninterrupted, low-cost power for its customers.
