American Transmission Company (ATC) and its corporate manager, ATC Management Inc., collectively ATC, on Oct. 20 filed with the Public Service Commission of Wisconsin a quarterly progress report for the period July 1 through Sept. 30, regarding the Spring Valley-N. Lake Geneva Project, noting that gross expenditures on the project as of Sept. 30 were about $10.7m, or 15.22%, of the authorized total of $70.6m.
The project is in design for the transmission lines and all substations, with the exception of the Balsam substation. ATC added Balsam substation site preparation and grading work started in July and finished in September. The Balsam substation layout was modified to add an additional 138-kV switch, which will support a planned future substation in the area, the company said.
ATC said that the start of construction for the remaining transmission lines and substation projects are:
- North Lake Geneva substation – February 2018
- X104 North Lake Geneva SS to Balsam SS transmission line – February 2018
- Bain substation and Spring Valley substation – June 2019
- Y102 Balsam SS to Katzenberg SS transmission line – September 2018
- X105 Balsam SS to Spring Valley SS transmission line – January 2019
- 63141 Bain SS to Spring Valley SS transmission line – August 2019
The company noted that it applied for the Army Corps of Engineers permit project in May 2016. The Army Corps requested archeological surveys in all permitted areas to complete the Section 106 review, the company said. ATC sent the archeological and architectural field survey reports to the Army Corps and the commission during the quarter, and the Army Corps sent the reports to the State Historic Preservation Office. ATC also noted that it submitted to the Wisconsin Department of Natural Resources (WDNR) the construction site stormwater runoff permit application for the Line X104 segment.
The company noted that the project’s anticipated in-service date is December 2019.
