WASHINGTON, D.C. — The U.S. Department of Energy has issued a regional grid emergency order across 13 Mid-Atlantic and Midwestern states, including Pennsylvania, to prevent power disruptions during an unexpected autumn surge in electricity demand.
The emergency declaration was requested by PJM Interconnection, the regional grid operator managing electricity transmission for Pennsylvania and neighboring states. Grid officials cited a combination of unusually warm October temperatures—driving up overnight air conditioning use—and pre-scheduled autumn maintenance shutdowns at power generation facilities as the primary triggers for tight supply conditions.
Under the order, which remains in effect through Friday, Oct. 16, power plants are authorized to operate backup generators and temporarily run at maximum capacity, even if doing so exceeds standard environmental emissions and exhaust limits. The directive also allows grid managers to request that large industrial customers and commercial facilities switch to localized backup power.
Department of Energy officials emphasized that rolling blackouts are not anticipated and that the order serves as a proactive measure to maintain grid stability. Similar temporary grid emergency declarations were issued earlier this year in other regions, including the Southwest, during severe heatwaves.
