Record‑breaking autumn heat has pushed electricity demand in the PJM region to historic levels, prompting the nation’s largest grid operator to act swiftly. On Oct. 13, PJM Interconnection issued a Capacity Advisory, a Maximum Generation Alert, and a Load Management Alert, and the Department of Energy (DOE) granted a combined emergency order that will remain in effect through Oct. 16.
Why the emergency measures were needed
September 2026 was the warmest month since records began in 1895, averaging 69.4°F—about 1.5°F hotter than the previous year. The unusually high temperatures have driven a 2.2% rise in average peak consumption for the first seven months of 2026 compared with the same period in 2025. PJM’s statement warned that baseload demand is outpacing new capacity and that unpredictable weather leaves fewer days for essential maintenance on generation and transmission assets.
What the alerts and order do
The newly‑created Capacity Advisory, approved by PJM members in June 2026, gives early notice when projected demand threatens to exceed available generation. It also triggers a recall of scheduled maintenance outages, ensuring that plants remain online during the critical period.
The DOE’s emergency order, known as a 202c order, provides temporary relief from certain environmental permitting restrictions for generating units. It also authorizes PJM to request that large‑load customers—such as data centers—activate backup generation, and it makes up to 35 gigawatts of unused backup capacity nationwide available as a last‑resort measure before a Level 3 Energy Emergency Alert would be declared.
Impact on families and businesses
U.S. Secretary of Energy Chris Wright emphasized that the order is intended to keep “millions of American families and businesses across the mid‑Atlantic” supplied with affordable, reliable electricity. Nonetheless, the Energy Information Administration projects wholesale electricity prices in the PJM footprint could rise 41% in 2026 compared with 2025, and households in the District of Columbia have already seen a 7% increase in utility bills as of July.
Utility companies are responding with relief programs. Exelon, which operates several regional utilities—including Atlantic City Electric, Baltimore Gas and Electric, and PECO—has launched the “Exelon Promise,” directing $60 million in assistance to low‑income families and exploring battery‑storage projects to capture excess power for use during peak periods.
Looking ahead
PJM acknowledges that the traditional “fall shoulder” period—when temperatures normally ease and maintenance can be performed safely—has become riskier as climate change drives hotter, longer seasons. The operator is working with state and federal policymakers to accelerate new generation connections and to remove permitting barriers that lie outside its jurisdiction.
While the emergency alerts are a necessary safeguard, they also underscore the need for long‑term solutions that expand reliable supply, protect consumers from soaring rates, and preserve the stability of the nation’s power grid.
