PJM Pushes Toward All-Time Peak Record as DOE Emergency Orders Target Large Loads
PJM has a Maximum Generation Alert and Load Management Alert in effect for July 3, with a Hot Weather Alert covering the entire footprint through at least July 4.
The numbers are historic. PJM served a preliminary hourly integrated peak of 161,910 MW on July 1. The July 2 forecast of 166,241 MW would break PJM's all-time summer record of 165,563 MW — a mark that has stood since 2006. PJM activated Pre-Emergency Demand Response across the footprint on the afternoon of July 2 to shore up reserves for the evening peak.
Behind the alerts sit two DOE emergency orders under Federal Power Act Section 202(c). Order No. 202-26-33 authorizes transmission owners — as a last resort before voltage reduction or load shed — to curtail data centers and other large loads that have backup generation. Order No. 202-26-32 grants generating units temporary relief from environmental permit restrictions, effective July 1 through July 3, and PJM has asked DOE to extend it through July 6.
Why the Large-Load Curtailment Order Changes the Playbook
Every operator knows the standard emergency ladder: max gen, DR deployment, voltage reduction, then firm load shed. This week PJM inserted a new rung — directed curtailment of data centers and large loads with on-site backup generation — ahead of voltage reduction. If your footprint has large flexible loads, expect this concept to show up in your EOPs sooner than you think.
For control room staff, the compliance work is happening in real time. Every alert declaration, DR deployment, and 202(c) action generates documentation obligations under EOP-011 capacity and energy emergency procedures — and your logs from this week are your evidence later. Generator operators running under the environmental waiver need to track exactly which hours they leaned on Order 202-26-32, because that relief expires and the permit reporting doesn't.
Transmission planners and reliability coordinators should also note the signal DOE is sending: large loads with backup generation are now viewed as a dispatchable emergency resource. That assumption will shape interconnection terms, tariff design, and seasonal studies going forward.
EPG Solutions Can Help
Weeks like this one are won or lost on situational awareness — knowing where your system stands before the alert hits the wire. EPG Solutions works with control rooms on RTDMS and PGDA real-time situational awareness so operators see stress building across the interconnection, not just inside their own footprint.
