The U.S. Nuclear Regulatory Commission has authorized Duke Energy to extend the operation of its Oconee nuclear plant in South Carolina by 20 years. This decision allows the facility’s three units to continue operating until 2053 and 2054.
The renewal of the license at the Oconee nuclear plant
The extension of Oconee’s lifespan ensures a reliable source of electricity for millions of customers. Furthermore, the nuclear plant represents a substantial portion of Duke Energy’s clean energy generation, and its continued operation addresses the need to maintain a diversified and resilient electricity grid.
The license renewal was preceded by a thorough technical analysis that demonstrated the plant’s ability to operate safely over the extended period. Duke Energy has invested in upgrades such as vessel covers , steam generators , turbines , and auxiliary systems , ensuring operational efficiency and safety.
In 2024, the plant increased its capacity by 45 megawatts through optimization projects at its three units. These efforts are aligned with the company’s strategy to strengthen energy infrastructure in the face of the transition to a low-carbon system.
The Oconee Nuclear Power Plant provides reliable energy, supports thousands of skilled jobs, and has a positive fiscal impact on the local economy. The federal nuclear production tax credit has strengthened the profitability of these operations, allowing for stable rates for consumers.
The governor of South Carolina and other state leaders have expressed their support, underscoring the essential role of nuclear energy in regional economic growth and long-term planning.
With this renovation, Oconee becomes the first Duke Energy plant to be authorized to operate for 80 years. The company plans to replicate this model at other facilities such as the Robinson plant , reaffirming its strategy of extending the lifecycle of its nuclear fleet as a cornerstone of its energy transition.
The approval of the Oconee Nuclear Power Plant license expansion is a significant milestone for Duke Energy and provides significant learnings to use in finalizing license applications for our other plants.
