I&M to rebuild existing Colfax substation as part of Central South Bend Reliability Project

Indiana Michigan Power (I&M), an operating unit of American Electric Power (NYSE:AEP), on April 14 said that it plans to rebuild and upgrade the existing Colfax substation on Colfax Avenue in Indiana as part of its Central South Bend Reliability Project in Indiana.

All of the equipment at the existing substation will be removed, and an entirely new substation will be built at the same location, the company said.

I&M said that the new construction will allow it to place lines entering and exiting the station underground, reducing the number of poles and overhead wires at the location.

By rebuilding the Colfax substation, a new substation along Niles Avenue will no longer be necessary, the company said, adding that it does not intend to pursue plans to build there.

The decision was reached following a comprehensive siting study, thorough evaluation of alternative sites, public input received during and after a public open house in February, as well as evaluation of additional information from city and community representatives, I&M said.

As TransmissionHub reported, I&M on Feb. 13 said that it is launching the approximately $20m Central South Bend Reliability Project, which is the fourth of six projects that are part of the $170m Powering Up Greater South Bend Program.

That program involves upgrading, replacing, and modernizing aging facilities to better serve customers and support economic development, the company said at that time.

The Central South Bend Reliability Project’s website now notes that that the project includes building about two miles of new transmission line, built to 69-kV standards, that will connect a new Muessel substation and the existing Colfax substation. The project will allow for the retirement of the Drewry substation, according to the site.

The website also noted that most of the line will be built underground and operated at 34.5 kV. According to a project fact sheet, most of the line will be east of the St. Joseph River and located under the roadway and the East Bank Trail. The fact sheet further noted that transmission line and substation construction would begin in 2018, and the facilities would be energized in 2019.
