Mount Pleasant Tech Interconnection Project (MPTIP)

Mount Pleasant Tech Interconnection Project Information

Project Summary


  • Construct the new Mount Pleasant Substation south of Braun Road along the east side of County Trunk Highway H to provide electrical service for the Foxconn campus.


  • Electrically connect the existing 345-kilovolt transmission lines near the development site and construct two sets of double-circuit transmission lines (four circuits) along a 1.2-mile corridor to connect to the new substation.


  • Add a second 345-kV transmission circuit to an existing transmission line between Racine and Pleasant Prairie.


  • Perform modifications at the Racine and Elm Road substations, and at the Pleasant Prairie switchyard.


  • Applicant's Stated Need: Due to Foxconn’s forecast for electricity usage at its new Mount Pleasant, WI campus, ATC is developing a project to construct a set of new electric transmission lines and a substation to serve Foxconn, in addition to modifications of existing transmission lines, structures and substations. The existing electric transmission and distribution systems in the area cannot accommodate the additional loads expected from the Foxconn development and other associated development.

  • Project Cost: The estimated Project cost is approximately $130 million.


  • Proposed Project Schedule:


    ATC anticipates filing an application on February 1, 2018

    PSC Review Spring and Summer 2018

    Commission decision expected August 2018.

  • Project Location (see map): The Project is located primarily in Racine and Kenosha Counties.
