DOE allows PJM to curtail data center power to prevent blackouts
The Department of Energy approved PJM Interconnection's request to curtail power to data centers and other large energy consumers in the Northeast and mid-Atlantic. This emergency measure was taken to prevent blackouts during an unexpected heat wave that caused tight power reserves. The action specifically aimed to alleviate stress on the grid in Maryland and Virginia by allowing data centers to use their backup generation.
The U.S. Department of Energy has granted an emergency order allowing PJM Interconnection, the largest wholesale power market in the nation, to curtail electricity usage by data centers and other major industrial consumers. This decision came in response to an urgent request from PJM, citing critically tight power reserves amidst a severe heat wave sweeping across the Northeast and mid-Atlantic regions. PJM, which services approximately 67 million people across 13 states and Washington D.C., issued an emergency warning due to the strain on the grid.
Specifically, PJM's request to the Federal Energy Regulatory Commission (FERC) on Sunday highlighted "stress conditions" and projected "peak demands and extreme heat for several straight days" in Maryland and Virginia. The grid operator emphasized that directing data center customers with backup generation facilities to switch to their own power sources would be crucial in averting potential rolling blackouts.
This emergency directive, granted by the DOE, is set to remain in effect through Wednesday, underscoring the immediate need to manage energy consumption during periods of high demand and environmental stress. The measure aims to stabilize the regional power grid and ensure continued service for millions of residents.
