Energy Department Issues Emergency Orders for Mid-Atlantic Power Grid Amid Heat Wave
The order lets PJM tap backup power and extra generation to avert blackouts as demand is forecast to hit 166.3 gigawatts.
- On Thursday, PJM Interconnection, the nation's largest regional grid operator, is forecasting record summer electricity demand of 166.3 gigawatts for Thursday evening, surpassing the 2006 record of 165.6 gigawatts.
- Over 250 million Americans face extreme conditions as a heat wave stretches from the Midwest to the East Coast, with 'feels-like' temperatures expected to reach 100 to 115 degrees Fahrenheit across much of the region.
- Data centers currently consume roughly 4.5 percent of U.S. electricity, while high temperatures reduce coal plant efficiency, according to Nikhil Kumar, program director of Gridlab. "Some coal plants in particular have efficiency issues and capacity losses due to high temperatures," Kumar said.
- The United States Department of Energy triggered an emergency across PJM, while New York City Mayor Zohran Mamdani announced the deployment of more than a dozen "cool vans" and opened hundreds of cooling centers for residents.
- Expanding AI infrastructure creates long-term grid vulnerability, as Mishal Thadani, CEO of AI platform Rhizome, noted that data centers require significant energy precisely when grid supply is tightest, with facilities pulling as much power as 100,000 homes.
