American Transmission Company (ATC) on Jan. 22 filed with the Public Service Commission of Wisconsin a quarterly progress report for the period Oct. 1, 2017, through Dec. 31, 2017, for the Spring Valley-N. Lake Geneva Project, noting that the project is in design for the transmission lines and all of the substations, except for the Balsam substation.
The Balsam substation fence and gate are getting installed, the company said.
As noted on the project’s website, the project 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
- 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
According to the Jan. 22 report, the schedule calls for construction to begin in:
- February on the North Lake Geneva substation, as well as on the X104 North Lake Geneva SS to Balsam SS transmission line
- September on the Y102 Balsam SS to Katzenberg SS transmission line
- January 2019 on the X105 Balsam SS to Spring Valley SS transmission line
- June 2019 on the Spring Valley and Bain substations
- August 2019 on the 63141 Bain SS to Spring Valley SS transmission line
ATC added that it received the Wisconsin Department of Natural Resources (WDNR) construction site stormwater runoff permit for the Line X104 segment in December. The ACOE received concurrence from the State Historic Preservation Office that the project will not affect archaeological resources, the company said, noting that that concurrence was forwarded on to the commission.
The anticipated in-service date for the project is Dec. 31, 2019, ATC said.
The company also noted that gross project expenditures as of Dec. 31, 2017, were about $13.1m, or 18.51%, of the authorized total of $70.6m.
