PJM, America's largest?power grid operator said that it had ordered generators?to run at maximum output? and brought idle?power _plants?online immediately on Thursday night, due to the escalating heat dome.

PJM’s orders, as detailed on its website for emergency procedures, were aimed to preserve reliability, as it?sought?to maintain power on a network serving 67,000,000 people?across Mid-Atlantic, South, and Washington, D.C., and the world’s largest concentraion of data centers.

Even before the heatwave this week, PJM was 'trying to overhaul a shaky system that had been pushed to?the?edge by soaring?energy consumption from data centers and electric cars.

PJM’s “transmission security” action included preparing resources for demand-response to reduce electricity consumption if needed. Grid operators were also instructed to inform management, government agencies, and consider public conservation appeals.

The report did not order voltage reductions, or tell electric utilities to reduce power to their customers.

PJM didn't respond to a?request? for additional comments immediately.

All available resources are deployed to reduce the risk of a customer outage if transmission conditions worsen or if supply becomes tighter.

Practically, the move was made to avoid rolling blackouts and?other measures of last resort in a region including densely-populated Baltimore-Washington. (Reporting by Tim McLaughlin, Editing by Chris Reese & Jamie Freed).
