TransWest Express Transmission Line Project TransWest Express, LLC, has filed an application for a right-of-way to construct and operate a 600kV overhead direct current transmission line to cross public and private lands for the TransWest Express 600kV Project. The extra high voltage line is designed to carry renewable power generated in Wyoming to the Desert Southwest.
The project begins in south central Wyoming, crosses northwestern Colorado, crosses Utah diagonally from northeast to southwest and ends south of Las Vegas at the Marketplace hub in the Eldorado Valley area (near Boulder City, Nevada).
Western Area Power Administration (Western) plans to partially fund the project under the American Recovery and Reinvestment Act of 2009, and will be joint lead agency for the National Environmental Policy Act (NEPA) process. The project plans to provide 3,000 megawatts of capacity by 2015.
