Quanta Services has bagged a contract to provide engineering, procurement and construction (EPC) solutions for a subsegment of US electric utility PacifiCorp’s Gateway West Transmission Line Project in Wyoming.
The Texas-based Quanta Services’ contract is for the Aeolus – Jim Bridger subsegment of the Gateway West Transmission Line Project, under which nearly 1,609km of new high-voltage electric transmission lines are planned to be built across the US states of Wyoming and Idaho.
The Aeolus – Jim Bridger segment will comprise around 222km of single circuit 500-kilovolt (kV) transmission line that will link the new Aeolus substation near Medicine Bow, Wyoming, and the new Anticline substation near Point of Rocks, Wyoming.
The segment, known as Subsegment D.2, also includes about 8km of single circuit 345kV transmission line that will link the Anticline substation to a new line termination bay at the Jim Bridger Generating Station substation near Point of Rocks.
Overall, the Subsegment D.2 and the Gateway West Transmission Line Project come under PacifiCorp’s $3.1bn worth Energy Vision 2020 project, which aims to add up to 1.1GW of new wind by 2020, mainly in Wyoming.
Quanta Services said that it will include the contract for the Subsegment D.2 in its fourth quarter 2018 remaining performance obligations and backlog.
The company expects to commence engineering and procurement works on Gateway West Transmission Line Project by the year-end. Construction is slated to begin in the spring of 2019 with the Subsegment D.2 project targeted to be wrapped up in late 2020.
The Gateway West Transmission Line Project comprises two segments – D and E. Segment D will span nearly 785km from the Windstar substation near Glenrock, Wyoming, to the Populus substation near Downey, Idaho.
Segment D, which has been split into three subsegments D.1, D.2 and D.3, will include seven expanded or new substations. Eventually, Segment D will facilitate access to existing and new generating resources, including wind, and will transmit power from the sources to customers.
Segment E of the Gateway West Transmission Line Project, on the other hand, which is made up of two 500 kV single-circuit transmission lines, will span nearly 807.8km from the Populus substation to the Hemingway substation near Melba, Idaho.
