Anderson - ElwoodTransmission Line Rebuild Project

Indiana Michigan Power representatives plan power grid upgrades to improve electric reliability and efficiency for customers in Madison County. The Anderson-Elwood Transmission Line Rebuild Project involves:

  • Rebuilding about 15 miles 138-kilovolt (kV) power line between Pendleton Substation, off Dr Martin Luther King Jr Boulevard in Anderson, and Makahoy Substation off West Washington Street, just east of Elwood.
  • Upgrading equipment at Pendleton Substation.

The project strengthens the electric transmission system by replacing deteriorating wooden poles from the 1960s with modern steel poles. Most of the existing poles along the line have broken equipment. Upgrading the line with modern equipment improves the line's operational performance, reduces the likelihood of extended power outages and the need for frequent equipment repairs.

Crews plan to rebuild most sections of the power line in or near the existing right-of-way, which could require updating or supplementing current easements. Easements are defined land rights that property owners grant the utility to allow for the safe construction, operation and maintenance of the power line.

Company Officials expect construction to begin fall 2025 and conclude by early 2027.
