Where it stands

The US Department of Energy has issued emergency orders for the mid-Atlantic power grid to manage record electricity demand during a heat wave. To prioritize air conditioning, the Energy Department directed data centers to utilize backup generators. In New York City, 17,000 customers have lost power, and iconic Times Square billboards were dimmed to reduce grid strain.

Coverage from Reuters, Bloomberg, and CNN emphasizes that demand hit a record high on Thursday. Reports from Politico and The Hill highlight a collision between the data center boom and extreme weather. Regional impacts are noted in DC, which broke heat records, and Chicago, where alerts were issued for western suburbs.

Attention is now on PJM's hot weather operations as the grid braces for further record demand. Additionally, the Freedom Caucus has pointed to state failures regarding the PJM request.
