Jackson Road - Marshall Transmission Line Rebuild Project

Indiana Michigan Power (I&M) is upgrading the 34.5-kilovolt (kV) transmission line that connects the Jackson Road Substation to the Marshall Substation. The improvements in St. Joseph and Marshall counties are essential to ensure continued reliable electricity 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. To upgrade the line aging wood poles will be replaced with steel monopoles. Rebuilding approximately 13-miles of 34.5 kV transmission line to 69 kV decreases outages and speeds recovery of service when outages occur.

Project Updates

Summer 2017: I&M announced the final line route for the Jackson Road - Marshall Transmission Line Rebuild. The announcement follows an open house held in April, which provided information about the project and provided property owners with the opportunity to ask questions and provide input. Details around the final line route can be viewed on the interactive map above.
