Tuco-Yoakum-Hobbs 345 kV Transmission Line

The proposed 345 kV transmission line project from substations near Tuco, Texas to Yoakum, Texas to Hobbs, New Mexico will consist of approximately 159 miles of new 345 kV transmission lines. The line will be constructed entirely on new right-of-way (ROW) with a proposed easement width of 150 feet, and will cost an estimated $242 million dollars to complete.  The project will be funded by the Southwestern Public Service (SPS) through internally-generated funds involving numerous other utility companies. This line will substantially increase bulk power capacity and system reliability in the region, and is expected to be in-service in 2020.

Before construction can begin, the Texas Public Utility Commission (PUC) must grant a Certificate of Convenience and Necessity (CCN) for both the section from TUCO to Yoakum and for the section from Yoakum to State Line, and the New Mexico Public Regulation Commission must grant a CCN for the portion from State Line to Hobbs. The CCN application process determines the need for the project, the projected impact, and the line route. The first CCN from Yoakum to Texas State Line was filed with the Texas PUC on June 25, 2015 and was approved in the PUC’s Final Order on March 22, 2016. Information and updates on this portion of the project can be found at the PUC interchange by searching for docket number 44726 at:


The Tuco to Yoakum CCN was filed on June 29, 2016, but has not been approved at this time. Updates can be found at the PUC interchange by searching for docket number 46042.
