The U.S. Department of Energy issued an emergency order on July 26 authorizing the grid operator serving 17 states to deploy idle power sources as extreme heat threatens rolling blackouts across a territory stretching from North Dakota to Louisiana. The order directed Southwest Power Pool to dispatch backup generation resources before declaring the most severe emergency alert level, a last-resort measure intended to prevent rotating outages that could affect the 20 million people in SPP’s service area.
The emergency order, known as DOE Order No. 202-26-37, represents an expansion of federal intervention in grid management as summer heat continues to strain power supplies nationwide. Under the order, SPP can now direct backup generation to operate as a last resort before triggering an Energy Emergency Alert Level 3, which can precede rotating blackouts.
The order came shortly after SPP warned that emergency conditions are likely to persist during peak-demand periods in its territory. On Friday, a sudden loss of imported electricity left SPP with razor-thin reserves for possible power plant outages and falling renewable generation. SPP avoided outages that day through voluntary conservation appeals but expects the western territory’s highest demand of the week as temperatures rise above 90 degrees Fahrenheit.
SPP’s West region will remain under a conservative operations advisory until August 1, raising awareness of potential threats to grid reliability. According to SPP, the region is “likely to continue to experience advisories and energy emergency alert conditions, particularly during periods of high customer demand.” The grid operator typically functions as a net exporter of electricity because of its massive wind generation base, but last week’s heat meant neighboring grids could not provide additional power because they faced the same weather-driven high demand.
The emergency order is part of a broader pattern of federal grid interventions. The Department of Energy has issued multiple Section 202(c) emergency orders since June 2026, targeting regional grid operators including PJM Interconnection in the Mid-Atlantic, Duke Energy in the Carolinas, and various power plants across the country. These orders authorize utilities to operate power plants at maximum capacity, waive pollution limits, and deploy backup generation—measures considered last resorts before voltage reductions or rolling blackouts become necessary.
Energy Secretary Chris Wright said the order taps “an abundant supply of unused backup generation to maintain affordable, reliable and secure power for hardworking American families and businesses.” The DOE estimates more than 35 gigawatts of unused backup generation remains available nationwide, a reserve capacity that grid operators are now being directed to mobilize.
