On July 20, 2026, the Southwest Power Pool briefly declared its highest-level grid emergency – a situation reserved for when operating reserves have been depleted – only to face the same crisis again less than a week later. The second federal intervention in less than two weeks says something the spring reliability forecasts couldn’t quite capture: a grid that looks adequate on paper can buckle fast when the heat doesn’t let up.
The timing caught attention precisely because it wasn’t supposed to happen. The North American Electric Reliability Corporation released its 2026 Summer Reliability Assessment on May 19, finding that more than 58 gigawatts of new generation added across North America since summer 2025 had strengthened resource adequacy. The central U.S. wasn’t even on NERC’s watch list for elevated risk. Three regions carried elevated risk for the summer: New England, the Canadian province of Saskatchewan, and the Pacific Northwest. That was half the number flagged in the prior year’s assessment, when parts of the Midwest, Texas, and the central U.S. were all at elevated risk. And yet, by late July, it was the central U.S. that needed emergency federal intervention – twice.
The fine print in that May assessment offered a warning that deserved more attention. “The improved conditions we’re seeing shouldn’t be interpreted as saying that overall reliability risk is declining,” said John Moura, NERC’s director of reliability assessment and system analysis, during a webinar on the 2026 Summer Reliability Assessment. He was right.
A US Power Emergency Spanning 17 States
The U.S. Department of Energy issued an emergency order to keep Americans across 17 states powered during the region’s energy emergency brought on by hot weather conditions, directing Southwest Power Pool to dispatch specified generation units and to order their operation as needed to maintain reliability.
The order is effective on July 26, 2026, and shall expire at 11:59 PM CDT on August 3, 2026. The 17 states covered are Arizona, Arkansas, Colorado, Iowa, Kansas, Louisiana, Minnesota, Missouri, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, Utah, and Wyoming. The order also authorizes Southwest Power Pool to direct backup generation resources to operate as a last resort before declaring an Energy Emergency Alert Level 3, or during one. The order was issued pursuant to a request from SPP itself – meaning the grid operator determined conditions were serious enough that it needed federal authority to act before things got worse.
An Energy Emergency Alert Level 3 is the highest classification a grid operator can issue. It’s the threshold at which rolling blackouts – scheduled, rotating power cuts designed to prevent a complete grid collapse – can be ordered across a region. The DOE issued emergency Order No. 202-26-37, pursuant to Section 202(c) of the Federal Power Act, directing SPP to dispatch specified generation units and order their operation as needed to maintain reliability.
This Wasn’t the First Time in July
On July 20, 2026, the DOE had already issued an emergency order to mitigate blackout risks and keep Americans powered during the region’s energy emergency, directing Southwest Power Pool to dispatch specified units and maintain reliability, with the same authorization to use backup resources before or during an EEA Level 3. That order expired at 11:59 PM ET on July 21.
SPP remained under a Conservative Operations Advisory on July 20, with the emergency measures in force through July 21, 2026. Officials extended the advisory on July 22, July 23, and July 24, due to higher-than-normal loads, generation outages, seasonally hot temperatures, and lower-than-expected wind and solar output. A Conservative Operations Advisory doesn’t require the public to do anything – but it signals that grid operators are watching conditions closely and managing resources with very little margin for error.
Each intervention was issued under Section 202(c) of the Federal Power Act, a provision that allows the Secretary of Energy to mandate the operation of generating facilities during times of war or an emergency.
What Pushed the Grid to the Edge in This US Power Emergency
The conditions behind this emergency didn’t appear overnight. Several factors converged at once. Southwest Power Pool normally benefits from one of the nation’s largest concentrations of wind energy generation. But widespread extreme temperatures across much of the central United States sharply increased electricity demand in neighboring regions, limiting their ability to export power when it was needed most. According to the order, SPP reported concerns about increased electricity demand, potential reductions in wind and solar generation, possible generation outages, and continued hot weather conditions affecting the region.
The SPP emergency didn’t exist in isolation. The summer of 2026 has been a stress test for grids across the country. PJM, the nation’s largest grid operator serving parts of 13 states and Washington D.C., reached an all-time peak load estimated at 168,158 MW on July 2, according to preliminary figures. PJM’s previous peak record was 165,563 MW, set on August 2, 2006.
High temperatures across the U.S., particularly in the mid-Atlantic region, spurred the DOE to order PJM to maximize generation output during that early-July wave. Heat indices soared to 100 degrees in Chicago and Detroit, 110 in New York City, 112 in Philadelphia, 113 in Washington D.C., and 111 in Nashville. When air conditioning demand spikes simultaneously across dozens of cities, every megawatt of available generation counts.
Summer peak electricity demand grew by 11 gigawatts since 2025 – itself building on a 10-gigawatt increase the prior year. Data centers, manufacturing facilities, and large industrial operations are all connecting to the grid faster than planners can comfortably accommodate. Meanwhile, the grid is being asked to handle this with aging physical infrastructure while weather patterns grow increasingly unpredictable.
For context on what’s at stake financially: power outages cost the American people $44 billion per year, according to data from DOE’s National Laboratories. That figure covers lost productivity, spoiled food and medicines, emergency responses, and damage to equipment – costs that fall disproportionately on households and small businesses with no backup generation.
What the Emergency Order Actually Does
The order works by unlocking backup generation capacity that normally sits idle. DOE estimates more than 35 gigawatts of unused backup generation remain available nationwide. These are power plants that exist on the grid but don’t run under normal conditions – older natural gas units, emergency diesel generators attached to industrial facilities, and other reserve assets that require federal authorization to dispatch when doing so might otherwise create regulatory or contractual complications. Energy Secretary Chris Wright, in DOE’s order directed at PJM during the early-July heat wave, wrote that “additional dispatch of the Specified Resources is necessary to best meet the emergency and serve the public interest.”
The broader grid entered summer 2026 with more than 58 gigawatts of new generation added since summer 2025 – including 16.4 gigawatts of solar, 14.7 gigawatts of battery storage, 6.7 gigawatts of natural gas, and 1.6 gigawatts of wind. The problem is that solar and wind output can drop sharply during a heat dome – exactly the weather pattern that drives demand highest. Battery storage helps bridge short gaps, but prolonged periods of low wind and high overnight temperatures can exhaust storage reserves before morning demand kicks back up.
NERC‘s assessment identifies ongoing challenges that could strain the grid this summer. Accelerated demand, rapid growth of large loads, periods of low wind output, and the overlap of early summer heat with spring maintenance outages may challenge reliability. The SPP situation in July 2026 illustrated exactly this vulnerability: a grid with plenty of nameplate capacity on paper, but insufficient dispatchable power when the wind didn’t blow and demand stayed elevated through the night.

What to Do Now
The emergency order runs through August 3, 2026, but the conditions driving it – sustained heat, tighter grid margins, and reduced wind output – don’t disappear when the order expires. The SPP region covers a wide swath of the central U.S., and the same weather patterns affecting those 17 states are pushing eastern grids hard as well.
For anyone living in the affected region, the most practical step is reducing electricity demand during peak hours, typically 3 p.m. to 9 p.m. on hot days. Set thermostats to 78°F or higher when away, run dishwashers and laundry machines after 9 p.m., and avoid using ovens during peak afternoon heat. These aren’t just conservation gestures: every megawatt of voluntary demand reduction during a grid stress event directly lowers the probability of the broader system tipping into an EEA Level 3 declaration.
If you have medical equipment that depends on power – a home oxygen concentrator, a dialysis machine, a powered wheelchair – contact your utility now to register as a medically vulnerable customer. Most utilities in the SPP region maintain priority restoration lists for these households, but registration isn’t automatic. Waiting until a blackout is underway is too late. Keep a battery backup charged, know where your nearest public cooling center is located, and have at least 72 hours of water and non-perishable food ready. A grid emergency that tips into rolling blackouts during a heat wave stops being an inconvenience very quickly.
