St. Martins-Edgewood-Mukwonago Rebuild Project
Project overview
The St. Martins-Edgewood-Mukwonago Rebuild Project is a 14-mile transmission line replacement project. The existing 138,000 volt single-circuit transmission line will be replaced between the St. Martins substation in Franklin to the Edgewood substation in Big Bend to the Mukwonago substation in Mukwonago.
Proposed work
The work involves replacing the conductors and lattice tower structures, which are approximately 90-years-old. New, steel single-pole structures will replace the existing structures and will be placed within a few feet of the existing structures in the right-of-way.
The estimated cost of this project is $25 million and the project was approved in October 2015 by the Public Service Commission of Wisconsin. Additional details about the application are available for public viewing on the PSC’s website under Docket No. 137-CE-180.
