Mustang-Shell CO2 115 kV Transmission Line Project

The proposed Mustang-Shell CO2 115 kV transmission line project consists of approximately 9 miles of new transmission line between the existing Mustang Substation, located in Yoakum County, about five miles east of Denver City, Texas (half mile north of County Road 390) to the existing Shell Substation, located just over a quarter mile northeast of the intersection of FM 1939 and State Highway 214 in Yoakum County.

The Texas Public Utility Commission must grant a Certificate of Convenience and Necessity (CCN) for the project before construction. The CCN process determines the project need and impact as well as the line characteristics, such as substations and endpoints, and the line route. Xcel Energy (Southwestern Public Service Company (SPS)) filed a CCN application on September 27, 2017 (Docket Number 47585). The CCN documents are available to view on this page and on the Texas Public Utility Commission website.

The proposed Mustang-Shell CO2 transmission line will increase reliability and meet growing needs in the area.

Southwest Power Pool approved a Notice to Construct for the project on June 30, 2014.

The project is expected to be in-service by October 1, 2019.
