The U.S. Nuclear Regulatory Commission has renewed the operating license for Duke Energy's (NYSE: DUK) Robinson Nuclear Plant for an additional 20 years, extending operations until 2050.

The plant, located in Hartsville, South Carolina, generates 759 megawatts of electricity and powers approximately 570,000 homes. The facility supports nearly 500 jobs and contributes about $28 million annually in local taxes to the region.

Robinson's original 40-year operating license was granted in 1970. The facility received its first 20-year extension in 2010, allowing operations until 2030. This second renewal represents what the NRC calls a "subsequent license renewal."

"Extending the operating life of this proven asset helps us deliver low-cost, always-on electricity for customers while supporting jobs and energy security for the region," said Steven Capps, chief nuclear officer for Duke Energy.

Duke Energy has completed $1.7 billion in equipment upgrades at the facility. The company's nuclear fleet provides about 51% of customers' energy needs in North and South Carolina.

Robinson becomes the second Duke Energy nuclear facility to receive subsequent license renewal approval, following Oconee Nuclear Station in 2025. The company plans to seek similar renewals for all 11 operating units in its nuclear fleet.

The license renewal process requires comprehensive analysis and evaluation by the NRC to ensure safe operation during the extended period. Information for this article was based on a company press release.
