PacifiCorp has selected a joint venture between Burns & McDonnell and Hitachi T&D Solutions – a wholly owned subsidiary of Hitachi Ltd. – to build three large-scale substations in Wyoming in support of new wind projects.
The joint venture will design and build two new high-voltage greenfield substations and upgrade a third existing substation at the Jim Bridger Generating Station. Burns & McDonnell will provide engineering, procurement and construction services, while Hitachi will provide all large power transformers and gas circuit breakers for the projects.
The new 500/230 kV Aeolus and 500/345 kV Anticline substations are being added to provide grid support for the addition of more than 1 GW of new wind generation capacity being added to the regional power network (under PacifiCorp’s Energy Vision 2020 initiative).
The Aeolus substation will be located near Medicine Bow, and the Anticline substation will be located near Point of Rocks. 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 complete by the end of 2020.
