Plymouth Reliability Project

The new power line will connect to the proposed Plymouth 5 Substation that is needed to ensure electric reliability and address current and future energy needs in your community and the surrounding area. The substation and power line will relieve constraints on the current electric delivery system, improve reliability and support local energy demand.

The southwestern portion of the Plymouth Utilities service territory has reached near capacity in recent years. A new substation is necessary to improve service reliability for local utility customers.

The Public Service Commission of Wisconsin (PSCW) is the regulatory agency with the authority to approve or deny a project. In this case, ATC will propose two routes and, if the power line project is approved, the PSCW will select the final route.

The Preferred Route (blue line on the interactive map) interconnects with an existing 138-kV power line located near the village of Waldo and follows a path west primarily along town and county roads as well as an existing natural gas pipeline. The Alternate Route (pink line on the interactive map) interconnects with the same existing 138-kV power line at a point further to the north and largely parallels roads and power lines to the west. Both routes would end at the proposed Plymouth 5 Substation location near the intersection of County Roads A and V in the town of Mitchell. Only one of these routes would be selected if the PSCW approves the power line project.

Of the two routes studied, ATC identified a Preferred Route (blue line on the interactive map) that will cost less to build, have better electric power flow and fewer impacts on special or unique areas (e.g., waterways, important bird or wildlife areas, areas of historic or cultural significance, etc.).

Once ATC submits the application for the power line project, you can provide comments to the PSCW, either electronically or written, under docket number 137-CE-205. You may attend a public hearing and make your statements for the PSCW record.

Plymouth Utilities submitted an application for the proposed Plymouth 5 Substation in fall 2023. You can provide comments to the PSCW, either electronically or written, under docket number 4740-CE–106.
