The Energy Secretary issued an emergency order under the Federal Power Act requiring critical electricity generation facilities in the Mid-Atlantic region to remain available, citing concerns about grid stability, on Aug. 21.
Emergency orders of this type are rare and indicate that PJM Interconnection or a comparable regional grid operator flagged a capacity shortfall it could not resolve through normal market mechanisms. The order is one of the most serious tools available to the Energy Secretary to prevent power outages.
The identities of the specific generating facilities and the precise nature of the reliability threat were not disclosed in the announcement. The Mid-Atlantic region served by PJM includes parts of 13 states and the District of Columbia, covering approximately 65 million people.
The emergency action comes as U.S. electricity demand has been rising due to data center construction, electrification of transportation and manufacturing, and extreme weather events that strain both heating and cooling systems. Grid operators across the country have warned that the pace of power plant retirements has outstripped new generation construction in some regions.
For households and businesses in the affected area, the order is designed to prevent the kind of reliability emergencies that can lead to rolling blackouts or forced conservation measures. The fact that federal intervention was required suggests the market alone could not guarantee adequate power supply.
PJM Interconnection, the nation’s largest regional grid operator, has been managing increasingly tight capacity margins as coal and natural gas plants retire faster than replacement generation comes online. The organization has raised alarms in recent capacity auctions about the shrinking reserve margins available during peak demand periods.
The order will remain in effect until the Energy Secretary determines the reliability threat has passed. Federal Power Act emergency orders have been used sparingly in recent decades, underscoring the seriousness of the current situation.
State utility regulators in the Mid-Atlantic region are expected to monitor the situation closely as the fall demand period approaches.
