Critical grid infrastructure to connect the West
By the numbers
- 730 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 Boulder City, Nev.
- $3 billion estimated cost
- DC system terminals to be phased over time from 1,500 MW to 3,000 MW of transmission capacity

In the news
"A number of peer-reviewed studies have documented that the aggregate output of wind and solar plants spread over a large geographic area is much less variable than the output of plants clustered into a small area. Thus, a more robust grid can significantly reduce the cost of integrating wind and solar power with the grid by allowing larger power flows between regions as well as making it possible to access renewable resources from a greater diversity of areas."
