In February 2011, the Department of Energy issued a $343 million loan guarantee to help with the financing of the One Nevada Transmission Line Nevada (ON Line) project, a 235-mile, 500 kV AC transmission line capable of carrying 600 MW of power to the grid, running north-south between Ely, NV and just north of Las Vegas. 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. The project reached commercial operation in January 2014.
The project utilizes tubular guyed-V transmission towers, which have a much smaller footprint than most traditional transmission towers and, therefore, have less of an environmental impact. In addition, the three-piece design leads to easy and cost-effective construction.
The transmission line’s development produced approximately 400 construction jobs and provides approximately 15 permanent jobs.
ON Line is viewed as part of the transmission backbone that will bring wind and solar resources from Wyoming, Idaho, and Nevada to California and other major-load areas. ON Line also integrates northern and southern Nevada, which is critical to ensure the reliability and integrity of the western grid for decades to come. Approximately 90% of total project costs are sourced in the U.S. (including equipment and labor).
