Permian Basin - Culberson

Oncor continues to monitor West Texas load growth due to oil and natural gas production, mid-stream processing, and general population needs in the Permian Basin. As the state’s economy continues to grow, it is important to take steps to ensure that a reliable electric system is in place to support electric load growth. Specifically, Oncor proposes to construct an electric transmission line interconnecting the existing Permian Basin Switching Station, located in Ward County approximately 4 miles west of Monahans, Texas, with the existing Culberson Switching Station located in Culberson County approximately 17 miles south of the Texas/New Mexico state line and approximately 42 miles west of Mentone, Texas. Completion of the Oncor project will provide an effective solution that creates a transmission loop for serving the existing customers and future load growth anticipated in the Permian Basin and surrounding areas while adding valuable transmission capacity to the entire transmission system. This project will help ensure continued reliable electric service to the entire local region. 

•  Voltage and Structure Type - The project is proposed to be a double circuit 138 kV transmission line constructed on steel monopoles.
