DTE Energy is working to provide more than a dozen of communities on the eastside of Detroit with more reliable power by investing nearly $600 million to upgrade the electric grid along East Edsel Ford Freeway.

“We’re upgrading the voltage capacity of our older 4.8kV transmission lines and infrastructure to 13.2kV,” said Nick Lusk, project manager, Distribution Operations. “In addition to the increased capacity, the upgrades will improve the system’s overall reliability which means less service interruptions for homes and businesses in the area.”

The upgrades include:

  • Building two new substations. New substations reduce power outages and provides additional electric capacity to support new development and electrification.
  • Upgrading miles of overhead and underground infrastructure to the latest construction standards which will improve reliability for about thousands of customers.
  • Replacing wood crossarms with fiberglass crossarms on overhead power lines. Overhead power lines are prone to damage caused by strong winds, ice, heat and accidents.
  • Installing stronger utility poles.

These upgrades are all part of our strategic solution to make Detroit’s electric grid more modern, safer, and reliable.   

Customers in the area will receive periodic updates on the projects including road closure details if their home or business is impacted.
