The Department of Energy (DOE) issued an emergency order authorizing Southwest Power Pool Inc. to use certain energy resources to reduce the risk of potential blackouts, according to a July 21 statement from the department.
The order, issued on July 20 and signed by Secretary of Energy Chris Wright, stated that Southwest Power Pool (SPP) had asked the DOE to temporarily permit certain resources to operate beyond their normal limits to help ensure grid reliability.
SPP, the regional grid operator serving 17 states in the central United States, also sought authorization to access and deploy backup generation resources at data centers and other large industrial and commercial customer sites.
On July 20, SPP issued multiple warnings about the possibility of rolling blackouts across its service area as high temperatures drove electricity demand to record levels. One alert said SPP had been forced to rely on some or all of its operating reserves after several power plants unexpectedly went offline.
According to the order, Wright determined that additional power dispatch was necessary and that backup generation resources might be needed to address the energy emergency created by the expected strain on the grid.
The determination was based on several factors, including an anticipated electricity shortage and the potential loss of power to homes and local businesses, which could threaten public health and safety.
Wright authorized SPP to use the necessary resources to meet electricity demand. He also permitted the grid operator to deploy backup generation resources as a last resort before issuing an Energy Emergency Alert.
In its statement, the DOE said that the order took effect on July 20 and expired on July 21. The department said the measure helped reduce the risk of power outages across the regions served by SPP.
"The Trump Administration is tapping into an abundant supply of unused backup generation to maintain affordable, reliable, and secure power for hardworking American families and businesses," Wright said in the statement.
The DOE estimates that more than 35 gigawatts of backup generation capacity remains unused nationwide.
Wright said the previous administration's policies weakened the U.S. power grid, leaving Americans vulnerable during emergency events.
"Thanks to President Trump's leadership, we are reversing those failures and using every available tool to ensure Americans have continued access to affordable, reliable, and secure energy to power and cool their homes," Wright said.
As the Epoch Times notes further, On July 15, PJM Interconnection, the nation's largest electric grid operator that serves 13 states, announced a hot weather alert for its service region through at least July 17.
Such an alert is issued ahead of expected hot weather or high humidity to prepare power generation facilities and personnel to meet a surge in electricity demand.
The Midcontinent Independent System Operator, which serves 15 states, also issued an alert on July 15, citing above-normal temperatures, higher-than-forecasted loads, and power generation outages. The alert ended the same day.
The emergency alerts issued by power grid operators came amid intense heat in parts of the United States.
According to a July 22 forecast by the National Weather Service's Weather Prediction Center, "hazardous heat" is expected to continue this week over the southern United States before expanding through the Great Basin and across the Northern and Central Plains.
"Forecast highs range in the mid-90s to mid-100s with heat indices exceeding 105-115 degrees for some locations," the center said.
"Widespread major to locally extreme HeatRisk (levels 3 and 4/4) is expected, which indicates a level of heat dangerous to anyone without adequate cooling or hydration."
Amid the high heat, more emergency alerts may be issued by various power grid operators, and the DOE may issue additional emergency orders to address the situation.
Elevated temperatures for the current summer season are a continuation of last year's trend. In a Jan. 13 post, nonprofit organization Climate Central said that 2025 was the fourth-hottest year on record for the contiguous United States. The nine warmest years in the country have all been recorded since 2012.
According to data from Injury Facts, an online resource run by nonprofit safety advocacy organization National Safety Council, high heat was responsible for 253 deaths in the United States last year.
