ATC to hold open houses on Bay Lake Project preliminary routes

American Transmission Co. (ATC) will hold open houses in early October to present preliminary routes for three of four Bay Lake Project study areas.

The Bay Lake Project includes new transmission lines and substations to be constructed in northeastern Wisconsin and the Upper Peninsula of Michigan to ensure electric reliability and stability.

At the open houses, ATC staff will be on hand to discuss the preliminary routes with landowners.

The project includes:

  • A 345-kV line and a 138-kV line between the new Green Bay-area substation and the Morgan substation near Oconto Falls, Wis.
  • A 345-kV line from Morgan to the Plains substation near Quinnesec, Mich.
  • A 138-kV line from the Holmes substation in Menominee County and the Chandler and Old Mead Road substations in Escanaba, Mich.

Plans for transmission line and substation work in a fourth project area in Dickinson and Marquette counties in Michigan’s Upper Peninsula are temporarily on hold.

The Midwest ISO (MISO) recently announced it would conduct a Northern Area Study to address a number of transmission proposals and issues in Manitoba, North Dakota, South Dakota, Minnesota, Wisconsin and Michigan. The Bay Lake Project components in this area are being included in the MISO study, and ATC is deferring additional work in this area pending study results.

Consequently, no open house will be held for the fourth project area in October; open houses will be scheduled when ATC resumes work in this project area.

Total preliminary cost for the revised project components are estimated to be between $286m and $430m for the 345-kV facilities and $149m and $222m for the 138-kV facilities.
