The authorisation falls under section 202(c) of the Federal Power Act and aligns with President Trump’s Executive Order on declaring a national energy emergency.
The order, enacted under section 202(c) of the Federal Power Act, allows specific generating units within Duke Energy Carolinas’ network to operate at maximum capacity. This measure responds to forecasts from the National Weather Service, which predict temperatures exceeding 100°F (38°C) across parts of the Carolinas, driving higher electricity use for air conditioning.
US Secretary of Energy Chris Wright stated: “As electricity demand reaches its peak, Americans should not be forced to wonder if their power grid can support their homes and businesses. Under President Trump’s leadership, the Department of Energy will use all tools available to maintain a reliable, affordable, and secure energy system for the American people. This order ensures Duke Energy Carolinas can supply its customers with consistent and reliable power throughout peak summer demand.”
Duke Energy, a major electricity provider for North and South Carolina, notified the DoE on June 23, 2025, of potential challenges in meeting demand, warning of possible power outages in some areas. The emergency order permits Duke Energy to exceed certain air pollution limits temporarily and implement measures to boost power generation, reducing the risk of blackouts in the region.
The increased demand coincides with extreme weather conditions across the southeastern US, with similar challenges reported elsewhere. On the same day, parts of New York City experienced blackouts, prompting local utilities to urge energy conservation. The DoE’s action reflects efforts by the Office of Cybersecurity, Energy Security, and Emergency Response to maintain energy reliability during critical periods.
In a related development, Duke Energy secured an agreement with GE Vernova in April 2025 to supply 11 US-manufactured natural gas turbines, enhancing its capacity to meet future energy needs. The emergency order and infrastructure investments highlight ongoing efforts to strengthen grid resilience in response to rising electricity consumption and extreme weather challenges in the Carolinas.
