Granger - Benton Harbor Transmission Line Rebuild Project

    Indiana Michigan Power (I&M) is investing $92 million in strengthening the transmission system in northern Indiana and southwestern Michigan. Approximately 46 miles of 138-kilovolt (kv) line will be upgraded to provide a more stable and reliable source of energy. Modernizing the infrastructure sets up the power grid for projected growth in the area and updating the equipment speeds recovery of service when outages occur.

    Summer 2018 Indiana & Michigan Power (I&M) announces the Granger-Benton Harbor Transmission Line Rebuild Project and launches an informational Virtual Open House. Right-of-way activities will begin along the line route immediately and continue through Summer 2020.
