One Nevada Transmission Line

Summary

One Nevada (ON Line) is a 235-mile (378 km), 500-kilovolt, 600-megawatt power line that runs from Southern to Northern Nevada. NV Energy owns 25% of the transmission line and operates and offers the line's capacity under the terms of NV Energy's Open Access Transmission Tariff. Great Basin Transmission South owns 75% of the line.[1][2] The line runs from the new Robinson Summit Substation in Ely to Apex, connecting with the existing NV Energy Harry Allen Generating Station,[2][3][4] and uses tubular guyed-V towers on a single point foundation.[5]

History edit

Construction on the $510-million (equivalent to $696 million in 2023[6]) line began in 2010. The line provides a way to connect renewable energy projects along the eastern edge of Nevada with the existing electrical grid.[7]

In February 2011, the U.S. Department of Energy issued a $343-million (equivalent to $458 million in 2023[6]) loan guarantee to finance the project. The project also includes the new Robinson Summit Substation, interconnection to the Harry Allen Substation, expansion of the Falcon-Gonder Substation, and new telecommunication facilities.[8] The line was expected to be energized in 2013.[9] The line was energized in January 2014.[3]

The line may be part of the larger Southwest Intertie Project Transmission Line (SWIP) project which would extend the line north to Jerome County, Idaho. The extension would create a 501-mile-long (806 km) line.[10]
