Quanta Services (NYSE:PWR) on Nov. 1 said that it has been selected by Berkshire Hathaway Energy subsidiary PacifiCorp to provide engineering, procurement and construction solutions for the Aeolus-Jim Bridger Transmission Line Project, which consists of about 138 miles of single-circuit, 500-kV transmission line and about five miles of single-circuit, 345-kV transmission line.
The 500-kV line connects the new Aeolus substation near Medicine Bow, Wyo., to the new Anticline substation located near Point of Rocks, Wyo., while the 345-kV line connects the Anticline substation to a new line termination bay at the Jim Bridger Generating Station substation, the company said.
The project is a segment of the Gateway West Transmission Line Project, which is part of PacifiCorp’s $3.5bn Energy Vision 2020 plan that is expected to add more than 1,000 MW of wind generation and upgrade existing wind generation facilities in Wyoming, Quanta said.
Quanta noted that it will include the Aeolus-Jim Bridger project in its 4Q18 remaining performance obligations and backlog. The company said that it expects to begin engineering and procurement activities for the project by year-end, with construction starting in spring 2019. Quanta said that it expects to complete the project in late 2020.
As noted on the Gateway West Transmission Line Project’s website, Idaho Power and Rocky Mountain Power have jointly proposed the project to enhance reliability and deliver electricity from existing and new generating resources, including such renewable sources as wind.
The project would build and operate about 1,000 miles of new high-voltage transmission lines between the Windstar substation near Glenrock, Wyo., and the Hemingway substation near Melba, Idaho, the site noted. The project would include about 150 miles of 230-kV lines in Wyoming, as well as about 850 miles of 500-kV lines in Wyoming and Idaho.
