Tuleta - Coleto Creek Electric System Improvements

    AEP Texas will upgrade the regional electric transmission grid to support the increasing oil and natural gas production associated with the Eagle Ford Shale development. The Electric Reliability Council of Texas (ERCOT) determined a need for improvements to the transmission line and facilities was necessary for the reliability of the transmission network and service of increasing electric load. This project will build approximately 50 miles of double-circuit (only one circuit will be constructed initially) 138-kilovolt (kV) transmission line and two new substations. Bolstering the transmission system serving the area will also support economic growth and development.

    Landowner input on route study links to determine the proposed line route was gathered during and following open house events held in Pettus (August 19, 2014) and Goliad (August 21 and October 23, 2014). AEP Texas filed a Certificate of Convenience and Necessity (CCN) with the Public Utilities Commission of Texas (PUCT) on July 1, 2015. The CCN was approved by the PUCT on July 7, 2016.

    Project Updates

    Crews began construction of the transmission line last year with right-of-way clearing, gate installation and placing structures along the rights-of-way.
