​​​Cross-Tie transmission line 


(602) 250-2600

TransCanyon is in the beginning stages of a process to permit, site and develop the Cross-Tie Transmission Line. In 2016, entities charged with interregional transmission planning in the west—WestConnect, Northern Tier Transmission Group (NTTG) and the California Independent System Operator (CAISO)— began studying the benefits of the new line. Their work is expected to take two years. Simultaneously, TransCanyon is working with other regulatory and permitting agencies ​such as the Bureau of Land Management, the Nevada PUC, Utah PSC, local counties and other stakeholders to permit the line.

Target in-service date: Late 2024

Size: 500-kV

Length: 213 miles

Rating: 1,500 MW

Estimated Cost: $667 million

The Cross-Tie Transmission Line is a proposed 500-kilovolt (kV) line connecting PacifiCorp’s proposed Clover 500-kV substation in central Utah and NV Energy’s existing Robinson Summit 

500-kV substation in eastern Nevada. The 213-mile line would go into service in late 2024.​​

The line will increase transmission capacity, improve reliability, enhance flexibility and provide more access to a wider pool of renewable energy across the region. This project:
