The TransWest Express Transmission Project is an extra-high-voltage direct-current electric transmission system. The TWE Project will reliably deliver cost-effective renewable energy produced in Wyoming to the Desert Southwest region (Arizona, California, Nevada), ultimately helping contribute to a cleaner world, strengthen the electric grid, and provide much-needed electricity to millions of homes and businesses every year. The general route will begin in south-central Wyoming, extend through northwestern Colorado and central Utah, and end near Las Vegas. Under development since 2005, the transmission line is anticipated to begin construction in 2014.
