WAUWATOSA (WITI) — The Public Service Commission of Wisconsin approved on Friday, March 1st, the joint application of Wisconsin Electric Power Company and the American Transmission Company for authority to construct two 138 kV electric transmission lines and an associated substation in Wauwatosa.

The goal of the project is to increase reliability for the Milwaukee Regional Medical Center and growing electric loads in the western portion of Milwaukee County.

The Commission’s routing decisions favored above-ground transmission options when possible in an effort to protect ratepayers from undue costs of undergrounding. The Commissioners agreed that undergrounding is appropriate in very limited situations, generally to address technical or engineering concerns.

The total project cost as sited, including all transmission, substation, and certification costs, will be approximately $34 million.

The Commission-approved routes for the project are as follows:

  • East-West Section: The route begins at a proposed interconnection point located near 120th Street and West Diane Drive in the Underwood Parkway.  Route B(1) lies north of and parallel to Underwood Creek and the CP railroad until it crosses to the south side of the creek at 115th Street.  The route continues, following Underwood Creek, crossing the UP railroad, Watertown Plank Road, and STH 100.  The route then turns and continues east, crossing the USH 45 freeway, and then parallels the east side of the freeway south to Watertown Plank Road.  Turning east, the route follows the north side of the street until it reaches a point just south of the proposed MC Substation site.
  • North-South Section: The route begins at the 96th Street Substation and follows the east edge of the USH 45 freeway ROW behind the Parkside Pool Apartments, the Montessori School, and St. Therese Church properties north to Watertown Plank Road, crossing Bluemound Road and Wisconsin Avenue.  While the Commission will return to decide where undergrounding will begin at this section, the route will eventually reach a point just south of the proposed substation site.  The route then turns to proceed north into the substation.
