Three Rivers Transmission Line Rebuild Project

    Indiana Michigan Power (I&M) is rebuilding 69-kilovolt transmission line that connects the Moorepark Substation to the new Ripple Substation in Three Rivers. The improvements in St. Joseph County are essential to ensure continued reliable power is available for customers. The existing transmission infrastructure has reached an age where it is in need of replacement to improve electric service reliability for customers across the region.

    Rebuilding approximately 6-miles of transmission line and constructing a new substation decreases the likelihood of outages and speeds recovery of service when outages occur. Aging wood poles will be replaced with steel monopoles.
