Barney Davis to Naval Base 138kV Transmission Line

In January 2013, the Electric Reliability Council of Texas ("ERCOT") endorsed this project to improve service reliability in Flour Bluff, Corpus Christi, and Port Aransas, Texas areas, including the critical Naval Air Station Corpus Christi ("NASCC"). The project required ETT to construct a new 138-kV transmission line from ETT's Barney Davis substation to AEP Texas' Naval Base substation in Nueces County, Texas.

On May 16, 2014, ETT filed an amendment to its Certificate of Convenience and Necessity ("CCN") with the Public Utility Commission of Texas ("PUCT") to construct this 138-kilovolt transmission line in Corpus Christi, Texas. On May 21, 2015, the PUCT approved a final order granting a CCN for this project, following an agreement ETT reached with some 50 intervenors on a final route for the line of approximately 7 miles. Due to the location of United States Navy airfields relative to the project and other routing constraints, approximately 2 miles of the transmission line were approved to be constructed underground, the need for which was driven by Federal Aviation Administration ("FAA") regulations, safety concerns and environmental and other issues. ETT worked in coordination with and support of the Department of the Navy, the NASCC, and the City of Corpus Christi regarding the routing for this line.

On September 11, 2017, this project was energized and placed in-service. The project provides support to the Corpus Christi area transmission network and reduces the possibility of loss of electric load during certain network conditions, such as the scheduled maintenance of transmission facilities
