AEP Texas plans to upgrade the power grid in San Patricio County.
The project involves building about 18 miles of double-circuit, 345-kilvolt (kV) transmission line, with one line installed initially.
The Angstrom-Naismith Power Improvement Project is the result of new transmission service agreements signed with several large industrial customers and other additional new power load additions in the area.
AEP Texas representatives filed a Certificate of Convenience and Necessity (CCN) with the Public Utility Commission of Texas (PUC) in October 2021. The PUC determines the final line route based on information included in AEP Texas’ CCN application and landowner input, but the endpoints remain the same.
February 2021: AEP Texas invited landowners along the preliminary routing links to participate in two virtual town halls. These meetings provided landowners with an opportunity to learn about the project and ask questions of AEP Texas representatives.
October 2021: AEP Texas filed a Certificate of Convenience and Necessity (CCN) application with the Public Utility Commission of Texas (PUC).
May 2022: The PUC selected the final line route, based on information included in AEP Texas’s CCN application and landowner input
AEP Texas plans to use steel lattice structures.
Typical Distance Between Structures: 1250 feet*
Typical Structure Height: 130-160 feet*
Typical Right-of-Way Width: 150 feet*
*Exact structure height will vary based on topography and other constraints (for instance, crossing other transmission lines). Right-of-way requirements can vary, but will typically be 150 feet.
