Severe thunderstorms hammered Southeast Michigan on September 3, knocking out power to more than 260,000 DTE Energy customers and damaging homes across the region. Wind gusts hit 70 mph in some areas, downing trees and power lines. DTE deployed 400 linemen from out of state with 800 more arriving Thursday afternoon to restore service. The utility said 80 percent of affected customers would regain power by day’s end Thursday.
Scope of the outage
As of 11:30 p.m. Thursday, over 260,000 DTE customers lacked power, with the highest concentration in Oakland and Wayne counties. DTE’s outage map showed 265,000 interruptions at 11 p.m. The July 3 severe weather event had caused 168,000 outages for comparison. Wind gusts of 70 mph were recorded in Howell, while Detroit City Airport reported 51 mph gusts. The I-96 corridor saw the most significant damage to DTE infrastructure.
Damage across Southeast Michigan
Detroit’s east side sustained heavy damage, prompting the National Weather Service to plan a survey to determine if a tornado touched down. A tree fell on a home on Detroit’s west side, completely demolishing it with a family inside; one male was injured. Traffic lights went out at 80 intersections citywide. Downed trees, flooding, and stranded vehicles were reported across the region. Some roads in Livingston County’s Brighton Township remained closed Thursday evening.
DTE’s response and restoration timeline
DTE Director of Operations Jerry Tullio said 80 percent of customers impacted by the first wave would see service restored by end of day Thursday. The utility had monitored forecasts for days and pre-positioned crews before storms arrived. As of Thursday morning, over 2,600 DTE Storm Response Team members were assigned to handle restoration. Additional storms threatened late Thursday evening, and DTE prepared for a second wave of damage.
Safety warnings for residents
Detroit Fire Chief David Nelson urged residents to stay at least 25 feet away from downed power lines and assume all lines are energized. He stressed that if a line touches anything, residents should maintain distance and keep children away. If a power line has fallen on a home, residents must evacuate immediately and call 911. Downed lines can whip around, spark, or arc as they search for ground.
Final Thoughts
The outage underscores DTE’s vulnerability to severe weather despite advance preparation. With Meyka grading DTE a B+ and forecasting the stock at $151.15 by year-end, investors should monitor how quickly the utility restores service and whether storm damage claims affect earnings.
