US approves $3B HVDC transmission project

USA: The U.S. Department of the Interior and the Bureau of Land Management have approved the proposed $3 billion TransWest Express Transmission (TWE) Project after eight years of comprehensive federal environmental review.

The TWE Project is a high-voltage direct current (HVDC) electric transmission system designed to add 3,000 MW of “backbone” transmission capacity between the Desert Southwest and Rocky Mountain regions, reports EBR.

Designed to directly access diverse renewable energy supplies, the 1,175-km HVDC transmission line is expected to strengthen the resiliency and reliability of the western US electric grid.

During the estimated three-year construction period, the project TWE Project will extend from south-central Wyoming, to the site of a potential interconnection near Delta, Utah, and then to the Marketplace Hub near Hoover Dam in southern Nevada, which provides interconnections to the California, Nevada and Arizona grids.
