Bluffton - Van Buren Transmission Line Rebuild Project

    Indiana Michigan Power (I&M) will replace the 69-kilovolt (kV) transmission line that connects the Bluffton Substation - passing through the Liberty Center Substation - to the Van Buren Substation. The improvements in Grant, Huntington, and Wells counties are essential to ensure continued reliable electric 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 the approximately 20-mile transmission line will decrease outages and speed recovery of service when outages occur. The approximately $30 million investment includes removing the existing transmission facilities and replacing them with sturdier facilities of the same voltage. Aging wood poles will be replaced with steel monopoles designed to expand the distance between poles to reduce impacts to landowners.

    Project Updates

    Early 2019: Construction and restoration on the Bluffton-Liberty Center Transmission Line was completed in Summer 2018. Construction on the Liberty Center-Van Buren Transmission Line is still being constructed, and is expected to be completed by Late 2019. Restoration is expected to be completed by Spring 2020. 

    Spring 2017: I&M announced the final line route for the Liberty Center - Van Buren portion of the project. The announcement follows an open house held in June, which provided detailed information about the project and provided property owners with the opportunity to ask questions and provide input. The final line route for the Bluffton - Liberty Center portion was announced last fall. Details around the final line route can be viewed on the interactive map above.
