Olive - Reynolds 345 kVTransmission Line Rebuild

Indiana Michigan Power (I&M) representatives plan to upgrade the transmission system for customers across western Indiana through the Olive-Reynolds 345 kV Transmission Line Rebuild.

The project involves:

• Rebuilding approximately 68 miles of 345-kilovolt (kV) transmission line between Olive Substation off US Route 20 in New Carlisle and Reynolds Substation off N 25 E in Reynolds.
• Relocating approximately 2 miles of transmission line between State Road 16 and E Monon Road, east of Monon.
• Upgrading equipment at Olive Substation.

The proposed project improves operational performance of the power line by replacing aging infrastructure. The existing towers were built in the 1950s and no longer meet engineering and operational standards. Upgrading to modern steel structures will ensure reliable energy delivery to the community.

Fall 2025: Company representatives announced the Olive-Reynolds 345 kV Transmission Line Rebuild in October 2025. If you would like to learn more about the project and our process, please visit the Virtual Open House.

O.R. Colan (ORC) serves as I&M’s right-of-way representative on this project. Landowners can expect to hear from a right-of-way agent to discuss field activities, construction and restoration.
