Auburn - Butler Transmission Line Rebuild Project

    Indiana Michigan Power (I&M) will upgrade the 69-kilovolt (kV) transmission line that connects the Auburn Substation to the Butler Substation. The improvements in DeKalb County are essential to ensure continued reliable electric service is available for customers. The existing transmission infrastructure has reached an age where it is in need of rebuild and redesign to improve reliability for customers across the region.

    Proactively rebuilding approximately 5 miles of 69-kV transmission line to 138 kV, constructing approximately 4 miles of new transmission line and making enhancements to support industrial customers decrease outages and speed recovery of service when outages occur.
