Stewart Road 345-kV Transmission Line Project

AEP Texas and Electric Transmission Texas, LLC (ETT) plan to address the need for a more robust and reliable transmission system in the Lower Rio Grande Valley by constructing additional electric transmission facilities to serve the area’s customers.

WHAT

Components of the Stewart Road Transmission Project include:

  • Construct approximately 5 to 9 miles of new 345-kV double-circuit transmission line
  • Expand the existing AEP Texas Stewart Road Substation

WHY

The Stewart Road 345-kV Transmission Line Project will strengthen the local electric grid and help to provide reliable electric service to the surrounding area while also addressing continued growth in the Lower Rio Grande Valley.


WHERE

The proposed transmission line route is comprised of highlighted route links shown on the project map. The final route will be determined by a regulatory process. On February 16, 2018, ETT submitted a Certificate of Convenience and Necessity (CCN) application tothe Public Utility Commission of Texas (PUCT) to seek approval to construct the transmission line. The route is expected to be approved by the PUCT in early 2019. Following regulatory approval, right-of-way agents will contact directly-involved landowners to discuss preliminary field activities and necessary 150 foot-wide easements. Construction of the line is expected to begin in 2019 and be completed in early 2020.


WHEN

On February 16, 2018, ETT submitted a Certificate of Convenience and Necessity (CCN) application to the Public Utility Commission of Texas (PUCT) to construct the transmission line. Once a route is approved by the PUCT in early 2019, right-of-way agents will be in contact with landowners to begin discussing preliminary field activities and necessary easements. Construction of the line is expected to begin in 2019 and be completed in early 2020.

Structures

Typical Structure Height: 140 to 155 feet
Typical Distance Between Structures: 800 to 850 feet
Typical Right-of-Way Width: 150 feet

*Exact structure type, height and right-of-way requirements may vary.
