Xcel Energy (NYSE:XEL) on Jan. 31 filed with the Public Service Commission of Wisconsin a report on behalf of itself and co-permittees, Dairyland Power Cooperative and WPPI Energy, noting that the final actual costs of the CapX2020 Hampton-Rochester-La Crosse 345-kV Transmission Project were about $199.4m.
The company noted that construction of the Wisconsin segment of the line was completed, and the line was energized, in September 2015. Following energization of the line, BNSF Railroad experienced signaling interference where the new line parallels the railroad tracks. Xcel added that the project team has worked with BNSF to develop a mitigation plan to address the problem and that the enclosed final costs include costs for the second phase of signaling mitigation, which is scheduled to be completed in the spring.
The company noted that the project’s approved cost estimate – including AFUDC and escalation – was about $211.1m.
As noted on the CapX2020 website, the final section of the project was energized in September 2016. The transmission line will improve reliability for the Twin Cities, Rochester and La Crosse areas, including rural electric cooperative customers in Goodhue, Olmsted, and Wabasha counties in Minnesota, as well as Buffalo, Trempealeau, and La Crosse counties in Wisconsin, the site noted.
The project used single-pole structures typically between 140 and 170 feet tall, the site noted, adding that typically, a 150-foot right of way was used.
