DOE Order 202-26-35 for PJM grid reliability: what to watch (July 14–21)

The U.S. Department of Energy has issued an emergency reliability order for the PJM Interconnection region ahead of a July heat peak—placing time-limited operational expectations on PJM to reduce blackout risk.

Under DOE Order No. 202-26-35, the order is effective July 14, 2026 at 11:59 PM EDT and expires July 21, 2026 at 11:59 PM EDT, as described by DOE. The order is issued under the Federal Power Act emergency framework when DOE determines an emergency exists because of sudden demand increases and/or shortages of generation or transmission capability.

What DOE ordered PJM to do

DOE’s order directs PJM to dispatch specified generating units and operate them to maintain reliability during the covered window. The intent is to increase the amount of available power to meet expected peak conditions in the PJM region during the hot-weather period.

What “backup generation” means here

A key part of DOE’s action is authority for PJM to use backup generation as a last resort. DOE describes this as usable before—or during—Energy Emergency Alert (EEA) Level 3 conditions, depending on how reliability conditions evolve.

It is important for residents to know that the order does not promise that backup generation (or any specific customer-facing action) will definitely be used. Instead, it sets operational authority and expectations for PJM during the July 14–21 period.

Where EEA Level 3 fits—and what residents can watch

In plain language, EEA Level 3 is the reliability escalation stage DOE/PJM reference as the point where actions can move toward more severe measures, including firm-load interruption risk later in the escalation path. DOE’s order ties the “last resort” backup-generation concept to the timing of EEA 3.

During the window, a concrete “watch next” signal described in DOE materials is whether PJM issues additional reliability alerts on the day DOE references for July planning—such as the Maximum Generation Alert and Load Management Alert (described as an EEA 1 in the order materials dated for July 15, 2026).

Demand response: part of the toolkit, not the same thing

PJM also uses demand response during reliability stress as a way to reduce electricity use when requested—typically through programs that compensate participating customers for reducing load when PJM calls for it.

That’s different from mandatory, emergency load shedding. DOE’s order references demand-side resources as part of the reliability toolkit as conditions worsen.

Bottom line

This is a time-limited DOE reliability intervention for the PJM region, running July 14–21, 2026. It requires PJM to dispatch specified units and provides authority for backup generation as a last resort tied to EEA Level 3. The most practical thing for residents to track during the week is whether PJM issues the reliability alerts referenced in DOE’s materials—especially any movement toward higher EEA levels.
