Sister Lakes Upgrades Project

The Sister Lakes Upgrades Project will strengthen the current electric transmission system in Western Michigan. Indiana Michigan Power (I&M) will build new power lines and substations, as well as update existing facilities to provide a reliable flow of electricity to its customers. The $45 million investment is critical for improved reliability and to accommodate for the region’s future growth.

Project components include:

  • Building two new substations (Keelette and Rothadew)
  • Constructing 7 miles of new 69 kV transmission line
  • Rebuilding 10 miles of 34.5 kV line to 69 kV
  • Constructing one new 1 mile 69 kV lines to the existing Sister Lakes Substation

Proposed Structures

I&M will build new steel, monopole structures ranging between 70 to 90 feet in height. The structures will be placed in the center of a 60-100 foot wide right-of-way corridor (depending on line voltage).

I&M is committed to meeting the energy needs of customers while protecting the environment and natural beauty of the region.
