Breaking: No Blackouts as Federal Order Keeps PJM Grid Stable
Households saw normal service during the October emergency, with Demand Response programs managing load without mandatory conservation.
By Kevin Iyer ·
The U.S. Department of Energy declared a power grid emergency across 13 states and the District of Columbia on Sunday, October 12, 2026. Energy Secretary Chris Wright issued the order under section 202(c) of the Federal Power Act. The directive granted PJM Interconnection temporary emergency authority to keep the regional grid stable from October 13 through October 16, 2026. For households in the affected areas, the period passed without any blackouts. No mandatory conservation orders were issued. Daily electricity use remained normal, and no action was required from residential customers.
PJM coordinates wholesale electricity for all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia. The grid serves about 67 million people. The regional picture from Illinois to the Carolinas showed a system under stress but holding firm. The emergency order allowed PJM to call on generators to run in excess of their operating permits as needed. It also authorized the grid operator to direct data centers and other large electricity users onto their backup generation if necessary.
The strain on the grid resulted from unusually warm October weather colliding with the fall shoulder season. During this period, generator and transmission owners take equipment offline for maintenance and upgrades ahead of winter. Most scheduled outages are prohibited in summer, so the maintenance window concentrates in the fall. On Friday, October 9, PJM issued a Capacity Advisory for Monday, October 12, and Tuesday, October 13. This was the first ever use of that procedure, which PJM members endorsed in June 2026. The load forecast was about 102,000 megawatts of peak demand on Monday and about 104,000 megawatts on Tuesday.
Paul Dajewski, PJM's senior manager for dispatch, told stakeholders that this volume of outages is typical for the shoulder season. He noted that previously scheduled generation outages totaled about 70,000 megawatts, plus planned transmission outages. On Monday, October 12, PJM issued a Maximum Generation Alert and a Load Management Alert for October 13. The grid operator extended the Capacity Advisory through October 14 and issued a Maintenance Outage Recall for that date. These actions followed a forecast of demand reaching approximately 111,500 megawatts or higher.
On October 13, PJM called on Demand Response programs to help manage the load. These programs pay customers who sign up in advance to cut electricity use when the grid is stressed. PJM said the alerts required no action from customers. A Maximum Generation Alert tells transmission and generation owners that conditions will be tight so they can defer or cancel equipment maintenance and testing. It also informs neighboring grid operators that exports from PJM may be curtailed.
Scheduled transmission line outages limited how much electricity could move between zones. Generation was bottled in some areas because of transmission limits. This was particularly true for resources serving congested zones in Washington D.C., Maryland, and Virginia, which include the BGE, Pepco, and Dominion zones. The Department of Energy said PJM wanted to deploy auxiliary, standby, directly connected, battery storage, or other generation resources at data centers. This included hyperscaler facilities and other large industrial and commercial customer sites.
PJM states that the shoulder-season reprieve is not what it used to be. Most of the new, rapidly growing demand comes from data centers and other energy-intensive large-load customers. Their consumption does not fall with the weather; it is a 12-month, 24/7 phenomenon. That expanding demand is outpacing new transmission and electricity supply coming onto the system. Unseasonably hot or cold weather now arrives outside the traditional peak seasons. PJM had also used Department of Energy emergency orders during two unseasonably warm September periods, August 31 to September 4 and September 15 to 18, to let eligible resources keep operating beyond normal limits.
In its Winter Outlook released on November 5, 2026, PJM expects sufficient resources to reliably meet demand this winter under expected conditions. Reserve margins continue to tighten as demand outpaces new supply. PJM expects 182,426 megawatts of operational capacity to serve a forecast winter peak of approximately 147,500 megawatts. The grid will also handle about 3,200 megawatts of average exports to neighboring systems. That peak, driven by demand growth, would set a new winter record if reached. Michael Bryson, PJM's senior vice president of operations, said the goal is to coordinate operations with generation and transmission owners to proactively manage the system.
