Texas CREZ Transmission Projects

Electric Transmission Texas, LLC (ETT) is proposing to build approximately 400 miles of 345-kV transmission lines as part of an extensive effort to deliver renewable energy to electric customers in Texas. These projects are a portion of a new transmission network that will facilitate the development of wind generation in areas called Competitive Renewable Energy Zones, or CREZ.

Following a mandate from the Texas Legislature in 2005, the Public Utility Commission of Texas (PUC) directed the Electric Reliability Council of Texas (ERCOT) to identify areas in the state that are best suited for wind generation development. A total of five areas in West Texas and the Panhandle were designated by the PUC as CREZ.

Once the CREZ were defined, ERCOT developed several transmission plans to deliver the CREZ wind generation to customers. The PUC selected the plan that was determined to be the most beneficial and cost-effective to deliver this renewable energy to customers. The overall plan includes approximately 2,400 miles of new 345-kV transmission lines and delivers about 18,500 megawatts of wind energy.

The following are the projects assigned to ETT and an updated progress report on each

  • Tesla to Edith Clarke Double-Circuit 345-kV Line
  • Edith Clarke to Clear Crossing Double-Circuit 345-kV Line
  • Clear Crossing to West Shackelford Double-Circuit 345-kV Line
