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.
Summer 2017: I&M announced the final line route for the Auburn - Butler Transmission Line Rebuild in March. Details around the final line route can be viewed on the interactive map above. Right-of-way agents are continuing to contact affected landowners to discuss the project and easement acquisition, where needed.
I&M will replace aging wood poles with steel monopole structures ranging between 85 and 125 feet in height. The structures will be placed in the center of a 100-foot-wide right-of-way corridor.
I&M is committed to meeting the energy needs of customers while protecting the environment and natural beauty of the region.
