American Transmission Co. (ATC) on Jan. 27 will hold its final public hearing on its proposed Spring Valley–North Lake Geneva Electric Reliability Project, which involves a new 25-mile, 138-kV line as well as a new 69-kV transmission line in Wisconsin.
The project is located in the south-central part of Wisconsin in Kenosha and Walworth counties, a company spokesperson told TransmissionHub on Jan. 13. The project begins at the Spring Valley substation in the town of Salem in Kenosha County, and ends at the North Lake Geneva substation in the City of Lake Geneva in Walworth County, the spokesperson said.
ATC plans to submit its application for the project to the Public Service Commission of Wisconsin in April, and if the project is approved, the PSC will select one route to be built, ATC said on Jan. 13.
If approved, construction of the estimated $72 million to $92 million would begin in 2017, and the project would be in service in 2019.
“The two proposed routes represent the options the project team members believe best meet state routing and siting criteria based on impacts, costs constructability, operation and maintenance,” Mary Carpenter, ATC senior local relations representative, said in the statement.
The project will provide system redundancy and allow for maintenance outages when repairs are needed, ATC said. The area where the project is planned is vulnerable to low voltages and power outages and can no longer adequately support the lower-voltage distribution system, ATC said.
According to the company’s project website, the project involves construction of a new 138-kV and 69-kV substation on an ATC-owned parcel along Hwy. 50 in the Town of Wheatland, or expansion of an existing substation site called Richmond Road in the Town of Randall.
According to the company’s project fact sheet, other components of the project include intermittent structure replacement between the Spring Valley substation and the Bain substation in Pleasant Prairie. As part of the project, the company will also rebuild the 69-kV line between the Katzenberg substation near Bloomfield, and the Twin Lakes substation.
The siting process began in early 2012, and initial corridors considered were evaluated and narrowed to include only the potential route options that were considered practical.
Depending on the route and substation site selected, other power line modifications may be needed, according to the ATC project website. Plans for the project were presented to the public in January 2013 and last March, according to the fact sheet.
