The Nuclear Regulatory Commission approved Duke Energy's Robinson nuclear power plant for a 20-year operating license extension on April 22, 2026, completing what the NRC described as the fastest subsequent license renewal review in agency history. Robinson is now licensed to operate until 2050, preserving 935 megawatts of clean baseload generation for the Carolinas and the broader southeastern grid.
Robinson, located in Hartsville, South Carolina, has operated since 1971. The subsequent license renewal process required comprehensive review of aging management programs, environmental impacts, and safety system upgrades. The NRC's record review time reflects process improvements implemented to handle a growing queue of renewal applications from utilities across the country.
The Southeast depends on nuclear power more than any other U.S. region. Nuclear plants in Georgia, South Carolina, North Carolina, and Tennessee collectively provide a substantial share of the regional grid's clean baseload capacity. Duke Energy's Carolinas nuclear fleet, Georgia Power's Plant Vogtle units, and TVA's nuclear plants in Tennessee form the backbone of southeastern electricity reliability as demand from AI data centers, electric vehicle charging, and industrial growth accelerates through the region.
Duke Energy said the Robinson renewal supports its clean energy commitments and grid reliability goals in a region where electricity demand is projected to grow substantially through 2030. Robinson joins St. Lucie Units 1 and 2 in Florida, which received subsequent license renewals from the NRC in May 2026, as part of a national wave of life extension approvals for the existing U.S. nuclear fleet.
