DTE Energy is upgrading its Wixom substation — a facility that controls the flow of electricity to homes and businesses — this year. This project will improve reliability for more than 10,000 customers in Wixom, Novi and surrounding communities.
Why this project is needed
These communities keep growing, and more homes and businesses mean more demand for electricity. The upgrades are designed to handle that demand, reduce stress on the grid and keep the lights on more reliably. Construction at the substation is planned from April 2026 through the end of 2028 with improvements expected to support the area for the next 25 years.
What’s changing
The project includes expanding the substation facility, adding a third transformer to deliver more electricity, and installing new advanced technology that gives crews better control over the system. It also adds the ability to reroute power more quickly during an outage, which means faster restoration times when problems do occur.
What this means for you
Beyond improving day-to-day reliability, the Wixom Substation Expansion reduces the likelihood of widespread outages and will help protect customers during peak demand periods. These improvements are part of DTE’s ongoing commitment to reduce outages by 30% and cut outage times in half by 2029 — while also laying the groundwork for future development in the area. Increased capacity will help support new homes, businesses and technologies as the electric system evolves to meet customer needs.
This project is part of DTE’s broader commitment to building the grid of the future. Through investments like this one, we are modernizing infrastructure, reducing outages and delivering safe, dependable service to the communities we serve.
We appreciate our customers’ patience during construction and will continue to share updates as progress is made.
