Case study

Energy Gateway South Transmission Line

Owner

PacifiCorp

Location

Wyoming, Colorado, and Utah

The Energy Gateway South transmission line is a new 416-mile, high-voltage 500kV line connecting Medicine Bow, WY, to just outside of Provo, UT.

Winco completed 413 miles of conductor installation across remote and rugged terrain, logging 6,407 flight hours. Their fleet executed precise aerial stringing using specialized helicopters and advanced tension-stringing techniques, minimizing the need for extensive ground access and reducing environmental impact.

Winco’s precision in wire-stringing enhanced project efficiency while prioritizing safety, reducing the need for ground crews in hazardous terrain. By streamlining wire installation, Winco contributed to the project’s completion and demonstrated the effectiveness of helicopter-assisted powerline construction.
