PacifiCorp announced Nov. 19 it had energized a 140-mile section of high voltage transmission line that will help connect Wyoming's renewable energy resources with the West Coast.

The section of line stretches from the newly built Aeolus substation near Medicine Bow, Wyo., to the new Anticline substation and existing Jim Bridger substation near Rock Springs, Wyo.

The line is part of the utility's $3.1 billion Energy Vision 2020 project, which includes developing 1,150 MW of new wind energy in Wyoming. It also involves repowering 900 MW of existing wind turbines in Wyoming and Washington to boost output by 25 percent and extend the life of the turbines.

The transmission project employs advanced technologies to improve voltage control and overall reliability of the system serving customers across the West under high renewable energy concentration, PacifiCorp said in a news release. These key segments are part of the company's ambitious multistate Energy Gateway transmission expansion project that began in 2007.

"This $700 million transmission project was completed on schedule and on budget, overcoming challenges resulting from the impacts of COVID-19 and before the onset of Wyoming's winter weather," Stefan Bird, president and CEO of PacifiCorp unit Pacific Power, said in a news release.
