Spring Valley-N. Lake Geneva Project in design for lines, two substations, ATC says

American Transmission Company on April 20 told Wisconsin regulators that the Spring Valley-N. Lake Geneva Project is in design for the transmission lines and two of the four substations associated with the project.

As noted on the company’s website, the project – which is designed to keep pace with growing electricity demand in southern Walworth and western Kenosha counties in Wisconsin – involves construction of:

  • A new approximately 23-mile, 138-kV transmission line stretching from the existing North Lake Geneva substation in southern Walworth County to the existing Spring Valley substation in western Kenosha County
  • The new 138-kV and 69-kV Balsam substation on an ATC-owned parcel along Hwy. 50 in the Town of Wheatland
  • A new 69-kV transmission line to connect the new substation to the existing Twin Lakes substation in Twin Lakes

In its April 20 quarterly progress report for the period Jan. 1 through March 31 filed with the state Public Service Commission, the company said that construction on the Spring Valley and Bain substations will begin in June 2019.

Construction on the X104 North Lake Geneva substation to Balsam substation transmission line began in February (vegetation management), while construction on the Y102 Balsam substation to Katzenberg substation transmission line will begin in September.

ATC added that construction will begin in January 2019 on the X105 Balsam substation to Spring Valley substation transmission line, and in August 2019 on the 63141 Bain substation to Spring Valley substation.

The company said that it received the Army Corps of Engineers (ACOE) permit for Lines X104, Y102, and 63141 on Feb. 15, and that ATC is working with the ACOE, as well as with the State Historic Preservation Office, to address a historic home identified as eligible for listing on the National Register of Historic Places on Line X105.

The project’s anticipated in-service date is Dec. 31, 2019, ATC said.

The company also noted that gross project expenditures as of March 31, were about $17.2m, or 24.3%, of the authorized total of $70.6m.
