US Issues Emergency Order for PJM Interconnection As Heatwave Approaches

U.S. Department of Energy declared an emergency on Tuesday across the nation's largest grid. They cited soaring supply and demand risks as extreme heat gripped the region.

The energy secretary stated in an order under Section 202 (c) of Federal Power Act that a statutory crisis exists in the PJM Interconnection region 'due to a mixture of surging demand for electricity and?limited production capacity.

PJM sent a formal request to the Federal Energy Regulatory Commission on June '29, warning that an "imminent emergency in electricity reliability" was imminent due to forecasts of temperatures?of 95 degrees Fahrenheit and higher.

PJM projects "peak?loads" of approximately 159.563 megawatts(MW) on the 1st July 2026, and approximately 162,860 MW for July 2nd 2026. These levels increase the risk of grid instability due to supply shortages.

Grid operator also warned that certain generation units may be restricted by a state or environmental permit.

The DOE said the order was necessary to ensure a sufficient supply of electricity and protect public safety.

PJM Interconnection is responsible for a 'large swath of eastern United States. Officials warned that if extreme weather conditions were not addressed, they could cause a system stress severe enough to affect the ability to meet the electricity demand.
