Critical grid infrastructure to connect the West
![Transmission Line Map](_images/map-highlight-v2.jpg)
The dotted line indicates the approximate route of this transmission line project, from the Marketplace Hub in Nevada to south-central Wyoming, with a 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.
By the numbers
- 732 miles of high-voltage transmission infrastructure consisting of two systems: a 3,000 MW direct current (DC) segment with terminals near Sinclair, Wyo., and Delta, Utah; and a 1,500 MW alternating current (AC) segment from the Utah terminal to southern Nevada.
- $3 billion estimated cost
- Three planning regions in the WECC connected by this interregional system

In the news
"A robust transmission grid provides consumers with access to lower-cost electricity. On a severely constrained transmission grid… consumers are forced to rely on local power plants even though plants in other regions can produce power more efficiently and at lower cost."
