Mortenson Construction was recently selected by investor-owned utility, Oklahoma Gas and Electric Company (OG&E) to build the Woodward EHV Thistle Transmission line project. The project will start at the Woodward EHV District Substation, 12 miles south of Woodward, Oklahoma, and run to the Oklahoma-Kansas border about two miles southeast of Hardtner, Kansas.
“This transmission line is essential to delivering Oklahoma’s wind potential and improving regional electric system capacity and reliability,” says Phil Crissup, VP Utility Technical Support.
All aspects of construction are currently underway, including placement of concrete foundations, setting of transmission line structures, stringing and clipping the bundled 1590 ACSR “Lapwing” conductor and optical ground wire.
The Minneapolis-based construction firm will be responsible for the installation of 474 pier concrete foundations ranging from 7 to 12 ft. in diameter and 18 to 50 ft. deep; setting 474 steel structures, and stringing the conductor along the route. Upon completion Mortenson crews will have strung approximately 5.6 million linear feet of wire.
Construction is expected to complete in September 2014.
