South Cass CountyTransmission Line Project

Indiana Michigan Power representatives plan power grid upgrades to improve electric reliability for customers in southern Cass County.

The project involves:

  • Building approximately 3 miles of 138-kilovolt electric transmission line connecting Surges Substation in Milton Township to an existing transmission line.
  • Expanding the existing Surges Road Substation near its current location.

The project strengthens the electric transmission system by providing an additional power source to the area and supports the growing demand for electricity.

Company officials expect construction to begin early 2023 and conclude summer 2024.
