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.
• Strengthens the transmission system between Utah and Nevada
• Relieves congestion on other key transmission line in the region
• Increases California, Nevada, Utah and Wyoming ability to import and export renewable energy
• Lowers energy costs because of access to additional energy resources
• Increases transmission capacity and access Energy Imbalance Market (EIM) and the California Independent System Operator members
• Grows tax revenue for local municipalities
• Creates construction jobs
Target in-service date: Late 2024
Length: 213 miles
Rating: 1,500 MW
Estimated Cost: $667 million
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.
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:
