Project Update

TransWest Express Project, US [free access]

January 6, 2017

Developer: TransWest Express LLC, a wholly-owned affiliate of The Anschutz Corporation, a privately-held company based in Denver.

 

Project details and status: The project includes the construction of a 725-mile (1,167-km), ±600 kV high voltage direct current (HVDC) overhead double-circuit transmission line, which will deliver renewable energy from wind energy projects near Rawlins in Wyoming to Colorado, Utah and Nevada. The line, after being connected with a substation located south of Las Vegas, Nevada, will interconnect with the power network of California Independent System Operator (CAISO) to deliver power in California.

 

The TransWest Express (TWE) is part of a series of transmission lines that will move energy produced in Wyoming (including energy produced by Power Company of Wyoming’s Chokecherry/Sierra Madre wind farm) to market states in the Southwest US.

 

In May 2015, the Bureau of Land Management (BLM) and Western Area Power Administration (WAPA) issued the final environmental impact statement (EIS) for the project. BLM accepted public comments on the EIS till June 1, 2015.

 

In December 2016, BLM approved the project. The BLM’s record of decision granted right-of-way (RoW) to the power line transmission project on BLM land, which covers about 60 per cent of the proposed route. If completed, the transmission line will provide 3,000 MW of additional capacity.
