Bay Lake Project – Michigan

Holmes-Old Mead Road

  • A single-circuit 138-kV line from the Holmes Substation in Menominee County to the Old Mead Road Substation in Escanaba.

When the Bay Lake Project was originally proposed, it included two new 138-kV lines between Menominee County and Escanaba. It was subsequently determined that a single transmission line will be adequate for the foreseeable future. This change allowed us to review opportunities to co-locate with existing transmission lines to minimize the amount of new right-of-way required. The proposed routes maximize the use of existing transmission line corridors and an abandoned railroad corridor.

ATC has a practice of engaging the public and other interested stakeholder in its proposed transmission line projects as a way to identify possible routes far in advance of filing a regulatory application. ATC began engaging the public through open houses in May 2012.
