Duke Energy has asked the U.S. Department of Energy for an emergency order under Section 202(c) of the Federal Power Act, citing concerns that extreme heat across the Carolinas could push electricity demand beyond available generation capacity and threaten grid reliability. The request, submitted June 11, seeks authorization for certain power plants to operate at maximum output levels through June 12, even if doing so temporarily exceeds air emissions or other environmental permit restrictions.
The utility said a prolonged heat wave is expected to bring temperatures into the mid-to-upper 90s across its service territory, with heat index values reaching as high as 106 degrees. Duke forecasts peak electrical demand of approximately 21,285 megawatts in its Duke Energy Carolinas territory and 13,345 megawatts in Duke Energy Progress territory. Company officials warned that some generating units may be unable to provide needed power because of environmental permit constraints, raising the possibility of customer load curtailments if additional generation cannot be brought online.
Duke Energy said it has already activated emergency operating plans and implemented conservation measures, including public appeals to reduce electricity use, demand response programs, voltage reductions, large customer curtailments, and purchases of additional power supplies. The company estimates these actions could reduce demand by hundreds of megawatts, yet it remains concerned that available resources may still fall short under the most extreme conditions.
For insurance claims professionals, the request highlights a growing operational challenge tied to extreme weather and energy infrastructure resilience. Prolonged heat events are increasingly creating conditions that stress electrical grids, raising the risk of service interruptions that can affect homes, businesses, healthcare facilities, manufacturing operations, and critical infrastructure. Any widespread outages during periods of excessive heat could lead to property losses, business interruption claims, spoilage losses, equipment damage allegations, and potential liability questions related to utility operations and emergency preparedness.
The filing also underscores the balancing act between environmental compliance and grid reliability during weather-driven emergencies. Duke is seeking authority for specified generating units to operate beyond emissions, fuel, and operational limits if necessary to prevent outages. The utility argues that the health and safety risks associated with potential power failures during extreme temperatures outweigh the temporary environmental impacts that could result from emergency operations.
For catastrophe and property insurers, the situation serves as another example of how climate-related weather extremes can create cascading infrastructure risks. While hurricanes and winter storms often dominate discussions about grid failures, heat-driven demand surges are becoming an increasingly important exposure factor, particularly in rapidly growing regions of the Southeast. The outcome of Duke Energy’s request may also draw attention from regulators, utilities, and risk managers evaluating future grid resilience strategies as electricity demand continues to rise.
