Stevens Point-Appleton Rebuild Project

Project Overview

  • ATC is proposing the Stevens Point-Appleton 345-kilovolt Rebuild Project in Portage, Waupaca, and Outagamie counties. 
  • The project includes rebuilding and upgrading an existing 345-kV power line between the Stevens Point and Appleton areas. ATC is currently evaluating alternative routes as part of the routing and siting process. 
  • The project is subject to review and approval by the Public Service Commission of Wisconsin.
  • The project was identified through the Midcontinent Independent System Operator’s long-range transmission planning process and is classified as a Multi-Value Project designed to support reliability and future energy needs throughout the region.

Project Need

The proposed project is needed to address aging infrastructure, improve reliability and support growing demand on the power grid. It will help address increasing demand on the transmission system and reduce system constraints to support current and future energy needs.

Project FAQ's

A:

The existing transmission system in the area is experiencing increasing demand and system constraints. 

The Stevens Point-Appleton 345-kV Rebuild Project is intended to improve transmission system performance, increase transmission capacity, and maintain reliable electric service in the region. The project will help address increasing demand on the transmission system and reduce system constraints to support current and future energy needs. 

A:

The PSCW is the regulatory agency with the authority to approve or deny major utility projects in Wisconsin. 

As part of the routing and siting process, ATC will develop and evaluate route alternatives for the project. If the project is approved, the PSCW will select the final route for construction.

A:

Yes. Public engagement opportunities will occur throughout the routing and siting process, including public open houses and opportunities to provide input on route alternatives. 

When ATC submits an application to the PSCW, the commission will establish a process for collecting public comments and receiving testimony during the regulatory review process.
