AEP Power Company (SWEPCO) is building a new 345,000-volt transmission line between Valliant, OK, and Texarkana, Texas. During the construction of the line near Texarkana, construction crews have used helicopters to perform work on the transmission line. Two aerial-service contractors, Erickson and Winco, performed the work to assemble and place transmission poles, transport workers, and pull wire between the structures. This method of construction is expected to help reduce impact to the land, and minimize damage to property. Construction of the 77-mile line began in Oklahoma in early 2014 and is expected to be complete in both Oklahoma and Texas in late 2016. The project was ordered by the Southwest Power Pool (SPP), the regional transmission organization responsible for overseeing the electric transmission grid in parts of Oklahoma and Texas to address regional reliability issues.
