OverviewApex – Phoenix Transmission Line Project overview image.jpg

A growing technology sector, excellent schools, and rich cultural and recreational opportunities ma​ke Ann Arbor a desirable place to live and work. This makes high-quality, reliable power increasingly important as homes and businesses are filled with sensitive electronics that can be affected by costly and inconvenient power outages.

To support electric reliability and increase capacity in the Ann Arbor area, ITC Michigan, through its ITCTransmissionsubsidiary, will construct approximately three miles of underground transmission line (PDF) to connect a new DTE Energy substation named Apex, located near the intersection of Huron Parkway and Hubbard Road, to an existing substation named Phoenix, located just north of Dhu Varren Road.

Why is this project necessary?

As in much of the United States, the electric infrastructure serving the Ann Arbor area was constructed decades ago and was not built to support modern-day demands. This can lead to inconvenient, and sometimes costly, power outages. The electric system improvements will enhance the reliability of electric service to Ann Arbor residents and businesses, and create additional capacity to support growth throughout the region.

Where will the project be located?

The Apex-Phoenix underground transmission line corridor will follow Dhu Varren Road east from the existing Phoenix substation, proceeding south along Nixon Road and Huron Parkway. It will connect to the new Apex substation near Huron Parkway and Hubbard Road.

When will this project start and how long will it take?
