Western MarionArea Improvements

Indiana Michigan Power (I&M) plans to strengthen the electric transmission system in Grant County, Northeastern Indiana.

Western Marion Area Improvements Project includes:

Rebuilding about 6 miles of 34 kV to 69 kV transmission line
Upgrading area substations including, West End, Marion Plant, Miller Avenue, Grant, South Side and Deer Creek Substations.

These improvements increase reliability, reduce power outages and speed recovery of service when outages occur.

Structures

I&M plans on using steel monopole structures averaging 75-feet in height. Structures will be placed within a 60-foot right-of-way.

Portions of the line will be built in or adjacent to the existing right-of-way, other areas will require construction in new areas and with new easements.

* Exact structure, height and right-of-way may vary
