Delivering Wyoming wind energy to the West
The TransWest Express Transmission Project is a high-voltage, direct current regional electric transmission system proposed by TransWest Express LLC. The TWE Project will reliably deliver cost-effective renewable energy produced in Wyoming to the Desert Southwest region (California, Nevada, Arizona), ultimately helping contribute to a cleaner world, strengthen the electric grid, and provide much-needed electricity to millions of homes and businesses every year. For example, Wyoming’s high-capacity wind energy resources complement California’s renewables, providing geographic diversity that helps Californians not only save money but also achieve GHG emissions reduction goals. Under development since 2005, the transmission line is anticipated to begin construction in 2015.
The dotted line indicates the approximate route of the proposed transmission line project, from the Marketplace Hub in Nevada to south-central Wyoming, with a potential future terminal near Delta, Utah. The TWE Project aligns with regional transmission development objectives set forth in an April 2005 Memorandum of Understanding signed by the governors of Wyoming, Utah, Nevada and California.

In the news
"Transmission is the biggest barrier to the development of Wyoming's considerable wind energy resources. But not only do we need to build the lines to carry this renewable energy to market, these lines must be 'right-sized' from the start. The key is to get the maximum number of electrons transferred with the least amount of environmental disturbance."
- Wyoming Governor Dave Freudenthal, 2009
