ATC: Gross project expenditures for Spring Valley-N. Lake Geneva Project as of June 30 were about $22.3m

Gross project expenditures for the Spring Valley-N. Lake Geneva Project as of June 30 were about $22.3m, or 31.5% of the authorized total of $70.6m, American Transmission Company (ATC) said on July 17.

As noted on the company’s website, the Public Service Commission of Wisconsin in March 2016 approved the project, which involves:

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

Studies indicate that the project will deliver benefits to the area by strengthening the electric system to meet the growing use of electricity, the company said, adding that the area electric transmission system is vulnerable to low voltages and power outages and will no longer adequately support the lower-voltage distribution system. The project will provide system redundancy and allow for maintenance outages when repairs are needed, the company said.

In its July 17 quarterly progress report for the period April 1 through June 30 filed with the commission, ATC said that the project is currently in design for the transmission lines and two of the four substations. The vegetation management for Line X104 is complete; the Balsam substation is in active construction; and construction is complete for the North Lake Geneva substation. ATC added that it has used appropriate landscaping and vegetation retention at the Balsam substation site to screen the new facilities from nearby residential development.

Construction on the Spring Valley and Bain substations is set to begin next June, the company said.

Regarding the transmission line construction start dates, the company said:

  • X104 North Lake Geneva Substation to Balsam Substation – February 2018 (vegetation management)
  • Y102 Balsam Substation to Katzenberg Substation – September 2018
  • X105 Balsam Substation to Spring Valley Substation – January 2019
  • 63141 Bain Substation to Spring Valley Substation – August 2019

Among other things, ATC said that the Wisconsin Department of Natural Resources issued two amendments to a permit that were in response to minor route adjustments submitted to the commission in March and April. ATC said that it continues to work with the Army Corps of Engineers and 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.
