TransWest Express Project

Map of proposed transmission lines of TransWest Express Project

The TransWest Express Transmission Project is a proposed extra high voltage, direct current overhead transmission line that would run about 728 miles from south-central Wyoming, crossing Colorado and Utah, to the Marketplace Hub about 25 miles south of Las Vegas, Nevada. This Project would include two AC/DC converter stations, about 200 acres in size at each terminating point, a fiber optic network communications system, and two ground electrode facilities, each about 600 acres in size. When completed, this Project would have the capacity to transmit about 3,000 megawatts of electricity generated primarily from renewable resources at planned facilities in Wyoming.

TransWest Express, LLC is proposing to construct, operate, maintain and decommission the TransWest Express 600-kV Direct Current Transmission Project.  TransWest Express, LLC is a wholly owned subsidiary of the Anschutz Corporation.

Western is supporting TransWest in the development of the Project through its Transmission Infrastructure Program, or TIP. TIP is a program that leverages Western’s depth of transmission project development experience and provides access to federal financing to eligible transmission infrastructure projects. The development phase determines whether a project can feasibly be constructed and includes environmental reviews, permitting, regulatory approvals, and technical design work.

Environmental review process:

Western and the Bureau of Land Management's Wyoming State Office are co-lead agencies for the preparation of the environmental impact statement, also called the EIS. Western maintains a separate webpage for this process. However, for the most current updates about the EIS, visit BLM's TransWest Express Project website. Redirecting to a non-governmental site
