TransWest Express LLC is developing and constructing critical high-voltage interregional transmission infrastructure to make America’s power grid more reliable and more resilient. The 732-mile line will reliably and cost-effectively facilitate delivery of approximately 20,000 GWh/year of electric energy.

The TransWest Express Transmission Project is a combination high-voltage direct current (HVDC) and high-voltage alternating current (HVAC) interregional transmission system connecting four major balancing authorities in the Western Interconnection. The TWE Project’s use of an HVDC segment, in combination with the HVAC segment, is an efficient way to move power long distances while expanding the grid’s flexibility and efficiency.

The TWE Project represents a multibillion-dollar investment in America’s power grid and intersects private, state and federal land. Its success means new well-paying jobs across Wyoming, Colorado, Utah and Nevada; hundreds of millions of dollars in local and state tax revenues; and hundreds of millions in state and federal payments. The BLM right-of-way grant was issued in 2017, all other authorizations were received by 2022, and the BLM Notice to Proceed to Construction was signed April 10, 2023. Project construction began in fall 2023.
