AEP Valliant to Northwest 345kV Transmission Line

Type: Transmission
Scope:
43.5 miles of 345kV
Location:
New Boston, Texas
Client:
American Electric Power (AEP)

Irby Construction was awarded the contract for the construction of the Valliant to Northwest Texarkana Transmission Line project for AEP Southwestern Electric Power Company (SWEPCO) and AEP Oklahoma Transmission Company near New Boston, Texas.

The Valliant-Northwest Texarkana Transmission Line project consists of installing 43.5 miles of 345kV single steel pole transmission line on anchor-bolted foundations that have previously been installed under another contract. This is the Texas portion of a larger 78.7 mile project that also included 35.2 miles in Oklahoma constructed by another contractor. The project is new single circuit construction with poles that are double circuit capable with steel arms only installed on one side of the poles.

This project was identified and mandated as a priority project by Southwest Power Pool (SPP) to connect an existing Public Service Company of Oklahoma substation to an existing SWEPCO substation in Texas. The transmission line goes from Valliant in McCurtain County, Oklahoma to Northwest Texarkana in Bowie County, Texas.

Several subcontractors have played an important role in making the Texarkana project a success. Irby Construction used Erickson Air Crane to erect poles with a heavy-lift helicopter as well as Winco, Inc., a subsidiary of Quanta Services, Inc., to provide helicopter erection.
