About the TransWest Express Transmission Project

The TWE Project is a new high-voltage interregional transmission system primarily designed to deliver renewable wind energy from Wyoming to the Desert Southwest region (California, Nevada and Arizona). The Project’s benefits include enhancing the stability of the existing transmission system, providing greater access to location-constrained generation resources, and assisting western states in meeting their renewable portfolio standards. The TWE Project is expected to be in service by late 2025.

The TWE Project includes a 3,000 MW high-voltage direct current (HVDC) system that will extend from Carbon County, Wyoming, to the existing Intermountain Power Project (IPP) 345kV switchyard near Delta, Utah, and a 1,500 MW high-voltage alternating current (HVAC) system that will extend from the TWE Project’s HVDC terminal in Utah to southern Nevada.

More detailed information is available in the Open Solicitation Information Memorandum, and on the TWE Project website.
