A proprietary energy industry newsletter shared with Baconโs Rebellion reports that the PJM Interconnection regional electricity grid probably set a summer record for demand on Thursday, July 2.ย The old peak of 165,563 megawatts in the 13-state region was seen in 2006.
The system maintained its service by activating demand reduction programs forcing big users to shed about 6,000 megawatts of load but never issued an order for the large data centers to turn on their backup generators.ย With the demand reduction efforts, Thursdayโs (and the weekendโs) peak was about 162,700 but if you add the shed load back in the old peak was passed.ย
A โdeploy all resourcesโ order was issued to Dominion and two other Mid Atlantic load serving entities for the first time since that was added to the emergency toolbox a decade ago.
This new peak claim is one observerโs conclusion and not an official PJM pronouncement. That will come later. Dominion Energy may have set a new summer peak.ย But the numbers cited match observations I made during the five-day hot spell, constantly opening the PJM Markets and Operations website to watch for a new peak.ย PJM was posting emergency directives not seen since last winterโs bitter cold spell.
