Like the Michigan roads, our electric infrastructure is aging and needs major upgrades. DTE Energy is making significant investments to build a more resilient, stronger and smarter electric grid.  

With an aggressive plan in place, we have already begun to make major upgrades in Wayne, Macomb, Washtenaw and Oakland counties.  

One of our initiatives is a massive multi-year electric vault underground project in downtown Pontiac.

The equipment which is housed in the vaults is corroding due to exposure to salt, debris and flooding, leading to power quality problems for customers. We are completely upgrading the underground electric system, and will replace all the vaults, cables and other electrical equipment with equipment designed to operate in this environment.  

Our crews replaced six of the 12 vaults and thousands of feet of cable. The plan for the rest of the year is to replace three more vaults and 10,000 feet – or nearly 2 miles – of cable.  

Customers in downtown Pontiac have experienced significant less outages since the work started in 2018.  The new equipment performed seamlessly through the past few storms and remained in service even through extensive flooding.   

Once the project is completed in the summer of 2020, the new improved equipment will result in fewer outages.  If an outage occurs, crews will be able to safely access the vaults to restore power more quickly.
