On November 7, 2025 NV Energy reported: In October, two large transformers were transported to the Walker River substation – the largest substation project in NV Energy history – as part of the Greenlink Nevada project.

Greenlink Nevada is a major transmission project that will create a triangle of transmission in the state – modernizing the grid, improving reliability for customers and ensuring we can meet Nevada’s energy needs.

Greenlink Nevada Updates – October 2025

Transporting Transformers

This month, two large transformers were successfully transported to the Walker River substation as part of the Greenlink Nevada project. Bringing the transformers to site required careful, complex collaboration, as each transformer measures 37 feet long,12.5 feet wide, and almost 14 feet high. They weigh approximately 343,000 pounds each.

The transformers were transported over railroad tracks as far as Yerington, Nevada, and were then hauled to the substation, just outside of Fort Churchill, Nevada, (PSTime’s Editor Note: should read “Fort Churchill Substation in North Mason Valley”) where they were offloaded and set on concrete foundations. Nevada State Police assisted with transporting the transformers, because they are so wide.

The Walker River Substation, located adjacent to NV Energy’s existing Fort Churchill Substation – which is also being expanded as part of the project – represents the largest substation project NV Energy has ever taken on and sits at the center point where Greenlink West and Greenlink North will meet.

Greenlink Nevada is a major transmission project and is made up of two parts. Greenlink West will be a 525 kV line that spans approximately 350 miles from Las Vegas, NV, to Yerington, NV. Greenlink West is expected to be in service by May 2027. Greenlink North will be a 525 KV line that spans approximately 235 miles from Ely, NV, to Yerington, NV. Greenlink North is expected to be in service by December 2028.

Transmission projects are often referred to as “energy highways” because they enable the transfer of electricity across long distances. These systems operate at various voltage levels to meet different regional and operational needs. In this case, the transformers will facilitate the connection between two transmission networks—one operating at 345 kV and the other at 230 kV—ensuring seamless energy flow between them.

Teams continue to work at the substation and along the Greenlink project. The completion of Greenlink West and Greenlink North – along with the existing One Nevada Line – creates a triangle of transmission in the state, ensuring we can meet the needs of our customers. Greenlink Nevada results in modernization of the grid, improves reliability for customers and positions NV Energy to meet Nevada’s energy needs.
