DTE Energy customers across Michigan are experiencing power outages, with the utility’s outage map showing active service disruptions affecting thousands of customers. The outage comes as DTE continues to address reliability concerns that intensified following a major storm event earlier this summer.
In early July 2026, a fast-moving severe storm swept across Southeast Michigan, cutting power to nearly 450,000 DTE Energy customers during the July Fourth holiday weekend. The scale of that outage prompted state regulators to launch a formal investigation into DTE’s storm response and preparedness.
On July 16, 2026, the Michigan Public Service Commission (MPSC) directed DTE Energy, Consumers Energy, and Indiana Michigan Power to file comprehensive reports detailing their responses to the July 3 storms. The utilities were required to submit these reports by August 27, 2026, according to the MPSC announcement.
DTE’s response to the investigation revealed that the company restored 100 percent of customers within 48 hours in three separate 2026 storms that affected between 57,000 and 80,000 customers. However, the July storm proved far more severe than the utility’s initial forecasts anticipated.
Consumers Energy said its worst-case forecast for the July 3 event called for 600 outages affecting 33,000 customers, according to reports filed with the MPSC. The actual impact exceeded expectations by more than tenfold, highlighting how rapidly developing storms can overwhelm utility preparedness models.
Michigan’s power grid has faced persistent reliability challenges. According to a 2025 report, it took an average of about 12 hours to restore power following an outage in Michigan in 2023, over twice as long as in any neighboring state. Fallen trees or branches are responsible for roughly 40 percent of outages in the state, making weather events a consistent threat to service continuity.
DTE customers can check outage status and report power outages through the company’s Outage Center at outage.dteenergy.com or by calling 800-477-4747. The utility maintains an interactive outage map that displays real-time information about service disruptions and estimated restoration times.
