North Edinburg-Loma Alta Transmission Project

On April 11, 2014, the Public Utility Commission of Texas (“PUCT”) approved a new 345-kilovolt (kV) transmission project from North Edinburg to near the Port of Brownsville. The project will be jointly constructed by ETT and Sharyland Utilities. ETT is a joint venture between the subsidiaries of American Electric Power (NYSE: AEP) and Berkshire Hathaway Energy Company.

The total transmission line project length is approximately 95 miles long. It begins at the AEP Texas Central Company’s (TCC) North Edinburg Substation in Hidalgo County and then continues to a location near the existing AEP TCC South McAllen Substation. From this point, the line would continue to its end point at the Brownsville Public Utilities Board (BPUB) Loma Alta Substation in Cameron County, located at the Brownsville Ship Channel.

The project is part of a larger effort known as the Cross Valley Project, which is needed in order to ensure reliable electric service for the Lower Rio Grande Valley, while also addressing continued growth in electrical load in the Brownsville area. The need for this project is the result of limited generation import capability and forecasted continued electrical demand growth in the region. ETT will be constructing the western portion of the line in Hidalgo County and Sharyland Utilities will be responsible for the east portion in Cameron County. The anticipated completion of the project is envisioned for 2016.

ETT acquires, constructs, owns and operates transmission facilities within the ERCOT, primarily in and around the AEP Texas Central Company and AEP Texas North Company service territories.
