Barney Davis to Laguna 138-kV Transmission Line Project

In November 2009 the Electric Reliability Council of Texas (ERCOT) approved a project to improve electric transmission service reliability in the Flour Bluff area specifically and the Corpus Christi region in general.

The project requires Electric Transmission Texas (ETT) to construct a new 138-kV transmission line to connect the Barney Davis Substation located at the Barney Davis Plant site and the Laguna Substation located northeast of the intersection of Hustlin Hornet Drive and Waldron Road.

The new line will improve transmission reliability by providing the Flour Bluff area with a direct transmission source from Barney Davis Plant and will complete a 138-kV transmission loop to supply electrical redundancy and to reduce the possibility of electrical transmission problems, particularly during scheduled maintenance outages of autotransformers at Airline Substation west of Oso Bay. At Laguna Substation, ETT is also required to construct a new 138-kV busbar and install a new 138 kV / 69 kV-autotransformer.

Once completed, this work is expected to improve electric service reliability for residents of the Flour Bluff peninsula and surrounding areas.

ETT is a new transmission utility co-owned by subsidiaries of American Electric Power (AEP) and Berkshire Hathaway Energy Company. AEP is the parent company of AEP Texas Central Company (TCC).
