MYR Group Inc. (MYR Group) subsidiary Sturgeon Electric Company, Inc. (Sturgeon Electric) has successfully finished construction of the 500kV One Nevada Transmission Line (ON-Line), an eagerly anticipated energy milestone that links Nevada Energy’s northern and southern power grids for the first time. The 235-mile high-capacity line became operational in January, 2014.
Sturgeon Electric’s skillful performance on the high-profile assignment set a new benchmark for the century-old company, said Mindie McIff, Sturgeon Electric’s Vice President, Utah T&D.
“We’ve never before constructed a 500kV line of this magnitude,” said McIff. “We completed it on time to the revised schedule, on budget, and it was a successful project that will help Sturgeon Electric move forward. There are a lot of large transmission lines anticipated in the west over the next 15 years, and the majority will be 500kVor higher.”
The $552 million ON-Line is the first phase of the Southwest Intertie Project (SWIP), a venture planned by Great Basin Transmission to build 510 miles of transmission line between Idaho and southern Nevada, where a shortage of transmission capacity has impeded development of renewable power resources. Senate Majority Leader Harry Reid of Nevada helped Great Basin Transmission obtain a $343 million federal loan guarantee to partially finance SWIP and provide greater access to renewable energy.
Over the course of the project, Sturgeon Electric crews installed over 11 million feet of three-phase triple-bundle conductor through 844 steel tower structures, working through all kinds of weather.
