Two new high-voltage greenfield substations will soon be constructed in Wyoming, and a third existing substation will be upgraded to provide grid support for the addition of more than 1,000 mW of new generation capacity being added to the regional power network.
PacifiCorp selected Burns & McDonnell and Hitachi T&D Solutions, a wholly owned subsidiary of Hitachi, Ltd., to design and build the substations. Burns & McDonnell will provide engineer-procure-construct services while Hitachi will provide all large power transformers and gas circuit breakers for the projects.
The new 500/230 kV Aeolus will be located near Medicine Bow, Wyoming, and the 500/345 kV Anticline substation will be built near Point of Rocks, Wyoming. Upgrades to the existing Jim Bridger substation, also near Point of Rocks, will provide added grid stability.
Engineering design is expected to begin this month with construction commencing in April 2019. The project is expected to be completed by the end of 2020.
