U.S. regional grid operator PJM activated demand-response customers to reduce electricity consumption amid high Mid-Atlantic and Midwest loads.

PJM activated demand-response customers to conserve electricity amid high loads in the U.S. Mid-Atlantic and Midwest, according to Financial_Express. The report describes an operational demand-reduction action, rather than merely a request to prepare for possible activation.

A subsequent message reports that the DOE issued an order addressing outage risks during hot weather. The order covered September 17–18 and authorized PJM to dispatch backup generation resources to support Mid-Atlantic grid operations.

The available messages do not quantify the electricity demand reduced or backup generation dispatched. They also do not identify participating data centers or report a specific data-center outage, so neither customer-level curtailments nor computing disruptions can be inferred.
