Approved Projects

Marshall - Hallsville Improvements

AEP Southwestern Electric Power Company (SWEPCO) is planning to rebuild approximately 11 miles of existing transmission line to upgrade aging infrastructure and to ensure continued reliable power. The line originates at a SWEPCO substation located near Highway 390 and Highway 80 west of Marshall and travels southwest to SWEPCO’s Hallsville substation located on North Oak Street. Upgrades include removing the existing wood poles and replacing them with steel monopoles and replacing the existing electrical wire with new.

Powering Up: Evenside – NW Henderson

AEP Southwestern Electric Power Company is planning to rebuild about 6 miles of 69-kilovolt (kV) transmission line in the Henderson area. These upgrades will strengthen the local transmission system and help to ensure continued reliability and adequate supply of electric power for the area’s growth and economic development. The company expects to invest nearly $9 million on this project.

Tuleta - Coleto Creek Electric System Improvements

AEP Texas Central Company (TCC) will be constructing a new double-circuit 138-kilovolt (kV) transmission line in Bee and Goliad Counties with only one circuit installed initially. The line will extend from the AEP TCC Tuleta Substation currently under construction, located near Highway 181 approximately two miles south of Pettus, and continue to the new Euler Substation at the intersection of Wilson Land, West Air Base Road, and F.M. 883. From there, the line will continue to the existing AEP TCC Coleto Creek Substation located at the site of the Coleto Creek Power Station approximately two miles northeast of the community of Fannin in Goliad County. The final route path has been approved by the Public Utility Commission of Texas (PUCT).

Valliant - NW Texarkana

The Southwest Power Pool (SPP) has identified and mandated a Priority Project to construct approximately 76 miles of new 345 kilo-volt (kV) transmission line to connect a PSO substation in Valliant, OK to a SWEPCO substation in Northwest Texarkana, TX. The Texas portion of the Valliant to NW Texarkana 345 kV transmission line was approved by the Public Utility Commission of Texas on Aug. 30, 2013, and is currently under construction.
