Plymouth Reliability Project

PROJECT STATUS: Complete

Project Description

Plymouth 5 Substation – Built by Plymouth Utilities as a separate project, this new substation serves area electric reliability and load needs.

ATC Power Line – A new, approximately 7-mile, double-circuit 138-kilovolt power line connects the Plymouth 5 Substation to an existing ATC 138-kV line.

Project Need

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

Additional information about the ATC power line can be found on the PSCW website, under docket number 137-CE-205. Additional information about the Plymouth 5 Substation can be found on the  PSCW website, under docket number 4740-CE-106.

Project FAQ's

A:

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

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

A:

The Public Service Commission of Wisconsin is the regulatory agency with the authority to approve or deny a project, as well as choose the final route, in the event of approval. In this case, ATC proposed two routes, the power line project was approved by the PSCW, and the PSCW selected the Ordered Route that is shown on the PDF map.
