One Nevada Transmission Line

One Nevada (ON Line) is a 235-mile (378 km), 500-kilovolt, 600-megawatt (800,000 hp) power line that runs from Southern to Northern Nevada. 25% of the transmission line is owned by NV Energy which 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, Nevada to Apex, Nevada connecting with the existing NV Energy Harry Allen Substation,[2][3][4] and uses tubular guyed-V towers on a single point foundation.[5]

History

Construction on the $510 million 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.[6] The line was expected to be energized in 2013.[7] 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 (806 km) long line.[8]
