La Palma - KingfisherTransmission Improvements Project


AEP Texas and Sharyland Utilities representatives plan to improve the transmission network in the San Benito region. Following Texas' winter storms in February 2021, the Electric Reliability Council of Texas (ERCOT) determined the need for transmission improvements. The proposed line strengthens the electric system by providing a second source of power, decreasing the likelihood and duration of wide, community-sustained outages.

The project:

  • Provides an additional transmission line and substation, adding resiliency against severe weather events
  • Establishes a second power line to ensure customers continue to receive power if the other area transmission line experiences an extended outage

Project Updates

AEP Texas and Sharyland Utilities officials hosted public open houses in March and April 2022 at the San Benito Cultural Heritage Museum. Landowners were invited to view detailed maps and talk with project team members about the proposed study segments.

Company representatives filed a Certificate of Convenience and Necessity (CCN) with the Public Utility Commission of Texas (PUC) following a review of public input on route link development and additional route analysis on June 29, 2022.

The PUC approved the CCN in January 2023.
