PSC approves ATC’s Monroe County-Council Creek Project

Plan includes new substation, rebuilding existing transmission line between Sparta and Tomah areas

MADISON, Wis. – American Transmission Co. on Tuesday received approval from the Public Service Commission of Wisconsin to build the new Timberwolf Substation in the Town of Tomah and upgrade an approximately 17-mile, 161- and 69-kilovolt electric transmission line from the Monroe County Substation in the Town of Sparta to the Council Creek Substation in the City of Tomah.  

 “The current transmission system that serves the area is aging and susceptible to overloads and severe low voltages,” said ATC Project Manager Andy Schaeve. “Rebuilding the 69-kV line and adding a new 161-kV line will help strengthen electric reliability for the area. The new line also will provide economic savings by reducing line losses and increasing access to lower cost power.”

The project involves replacing the structures and wires of the existing 69-kV transmission line and adding a 161-kV circuit to the new steel structures. Transmission line work will generally be completed within the existing right-of-way area. To allow for flexibility on the 69-kV system, ATC also will build the new Timberwolf Substation approximately 1/2 mile south of Interstate 90 along Highway 131.

ATC in July 2010 filed an application with the PSC to construct the project. The estimated project cost is $48 million. The line is expected to be in-service in late 2014.
