The 3 GW TransWest Express transmission project reaches new milestone (US)

10 Jun 2021

The 3 GW TransWest Express power transmission project, which offers 1.5 GW of power transmission services between Wyoming and Utah and 1.5 GW between Wyoming and Nevada (United States), has launched its initial capacity allocation process. The US$3bn project, which would run from Carbon County, Wyoming, to Clark County, Nevada, with an interconnection into the Intermountain Power system in Millard County, Utah, has already secured key permits and acquired nearly all rights-of-way. The 500 kV electricity transmission line would use both HVDC and HVAC technology. Construction would start after the BLM Notice to Proceed is issued and should take about 3 years. The project is expected to help Western electricity markets gain access to high-capacity wind power supplies from Wyoming.
