I&M plans to upgrade 69-kV line in Indiana, Michigan

American Electric Power’s (NYSE:AEP) Indiana Michigan Power (I&M) on Nov. 30 said that it plans to upgrade a 69-kV electric transmission line in LaPorte County, Ind., and Berrien County, Mich.

The New Buffalo Area Improvements Project would enhance the power grid to ensure a reliable flow of electricity to local customers, the company said.

According to a project fact sheet, the project includes rebuilding about seven miles of 69-kV transmission line, upgrading the Bosserman substation, and retiring the LaPorte Junction substation.

Most of the line would be rebuilt where it is currently located and may require supplemental right of way (ROW) easements, the company said, adding that alternative study segments are proposed in some areas and, if selected, would require new construction as well as acquiring new easements.

“The time has come to replace and upgrade the aging transmission infrastructure,” the fact sheet noted.

The existing wood poles would be replaced with steel monopole structures, which would range from about 75 feet to 90 feet in height and would be placed in a 60-foot-wide ROW corridor.

Of the project’s location, the fact sheet noted that currently, the line exits the LaPorte Junction substation. The project shifts to build the line out of the recently built Bosserman substation on Route 300 West in Michigan City, Ind., and crosses the state line to the New Buffalo substation on East Clay Street in New Buffalo, Mich., the fact sheet said.

According to the project schedule, transmission line construction would occur early 2019 to summer 2019; substation construction would occur summer 2019 to spring 2020; and the facilities would be placed in service in spring 2020.

According to the project’s webpage, a public informational open house on the project will be held on Dec. 14 at the New Buffalo High School & Middle School in New Buffalo, Mich.
