DTE officials monitoring electric amid extreme heat
July 1, 2026, 4:08 p.m. ET
DTE Energy officials say the vast majority of the company’s electrical infrastructure remains operational, but the extreme heat in southeast Michigan has caused scattered power outages across its coverage map.
DTE Director of Electric Distribution Jerry Tullio said on a Wednesday, July 1 media call that near-record temperatures did lead to equipment overheating at a substation powering parts of Warren.
“Overall, the grid is handling the heat so far,” Tullio said.
Tullio said the company’s first tactic to address heat-related outages is to reroute power to the affected area. If the outage persists, crews will be sent out for repairs. Equipment overheats due to overuse in the extreme temperatures, he added.
DTE’s outage map showed around 900 customers without power as of 3:30 p.m. Wednesday, including 126 in the area between 12 Mile and 13 Mile along Ryan Road in Warren. According to the company, 99.96% of customers had power at the time.
Officials will continue to monitor the grid amid the heat, Tullio said.
DTE provides electric service to around 2.2 million customers, mainly in southeast Michigan.
Safety tips for high temperatures
The National Weather Service in White Lake said the heat and humidity will present hazardous conditions for those participating in outdoor activities and for those who don’t have access to air conditioning.
They suggest residents:
- Reduce outdoor activity.
- Drink plenty of water.
- Wear lightweight and light-colored clothing.
