On October 12, 2026, the U.S. government ordered emergency measures for the power grid in the eastern United States due to the threat of supply shortages. Energy Secretary Chris Wright took this action in response to unusually high electricity consumption, numerous power plant outages, and constraints within the transmission network. The risk of blackouts was particularly acute in the regions around Washington, D.C., Baltimore, and parts of Virginia. Consequently, grid operator PJM was granted special authority to bring additional power generation capacity online and to activate emergency power facilities. The order, in effect from October 13 to 16, was intended to prevent unplanned power outages. However, by October 14, PJM reported that the situation was easing for the days ahead.

Risk of Blackouts Due to Insufficient Power Plant Capacity and High Electricity Demand
The situation was particularly critical on October 14. According to the grid operator’s initial calculations, available reserves could have fallen to as little as 900 megawatts. At the same time, PJM anticipated power plant outages totaling 61,591 megawatts—though these were primarily due to scheduled maintenance rather than unforeseen technical failures. Due to unseasonably high autumn temperatures, electricity demand reached levels more typical of the summer season.
PJM supplies electricity—either in whole or in part—to 13 U.S. states and the capital, Washington, D.C. For October 14, the grid operator projected a peak load of approximately 113,300 megawatts. The situation was especially strained in the service territories of Baltimore Gas and Electric, Pepco, and Dominion Energy. Furthermore, bottlenecks on key high-voltage transmission lines hindered the movement of electricity between regions, preventing the full utilization of available generation capacity.
US Government Authorizes Power Plant Operation Beyond Standard Limits
Emergency Order No. 202-26-50 is issued under Section 202(c) of the Federal Power Act. This provision grants the Secretary of Energy the authority to take extraordinary measures to ensure the security of the power supply. Consequently, PJM is permitted to operate certain power plants beyond their standard operational limits when necessary—including temporary exemptions from environmental regulatory requirements. The grid operator had requested this special authorization on October 11.
Furthermore, PJM may mandate that large electricity consumers utilize their own backup power systems. This applies, in particular, to data centers, industrial facilities, and other major energy users. Available reserves include, among other things, diesel generators, battery storage systems, and other decentralized power sources. However, these are intended for use only as a last resort—immediately before or during an “Energy Emergency Alert 3” (EEA 3), the highest level of emergency. Transmission and distribution grid operators are required to support these measures if necessary. According to the Department of Energy, there are more than 35 gigawatts of currently untapped backup power capacity nationwide.
Grid operator activates load management and brings power plants back
The blackout threat prompted PJM to carry out additional interventions on October 13th and 14th. The grid operator extended its warnings about scarce generation reserves and activated programs to reduce consumption. Participating major customers therefore had to temporarily reduce their electricity consumption. At the same time, PJM recalled planned maintenance shutdowns and restricted certain electricity deliveries to neighboring grid regions. The afternoon and evening hours in particular required additional reserves because solar power production decreased as the sun went down.
However, on October 14th, the network operator’s assessment changed. PJM said the additional power plant capacity was expected to no longer be needed on October 15 and 16. The emergency order will still remain in effect until the scheduled expiry. The process also highlights the growing difficulties in balancing maintenance work and electricity demand. Added to this is the increasing consumption caused by new data centers and other large consumers. According to a current Reuters report, PJM is planning network investments of around $12.2 billion. The expansion is intended in particular to improve security of supply and reduce existing network bottlenecks.
