Electric Transmission Texas (ETT) and Sharyland Utilities (Sharyland) filed a joint application with the Public Utility Commission of Texas (PUCT) to amend their certificates of convenience and necessity to construct the Cross Valley Project, a proposed 345-kV transmission line in portions of Hidalgo and Cameron counties in the Lower Rio Grande Valley of Texas. The proposed line would begin at the AEP Texas North Edinburg Substation in Hidalgo County then head east to the Brownsville Public Utilities Board Loma Alta Substation in Cameron County. ETT will construct the western portion of the line, and Sharyland will construct the eastern portion. The estimated cost for the project ranges from $314 to $405 million. The project is targeted for completion by summer 2016.
