Critical grid infrastructure to connect the West
By the numbers
- 732 miles of high-voltage transmission infrastructure consisting of two systems: a 500kV direct current (DC) system with terminals near Sinclair, Wyo., and Delta, Utah; and a 500kV alternating current (AC) system from the Utah terminal to southern Nevada.
- $3 billion estimated cost
- DC system terminals to be phased over time from 1,500 MW to 3,000 MW of transmission capacity
- June 7, 2021: Initial capacity allocation process begins for interregional TWE Project
- Feb. 26, 2021: FERC approves TransWest’s proposed process for allocating transmission capacity
BLM and WAPA are joint lead agencies that prepared an Environmental Impact Statement for the TWE Project. USFS was a cooperating agency. Each federal agency has an EIS-related site:
