Custer Mountain to Ponderosa 115 kV Transmission Line Project

The proposed Custer Mountain to Ponderosa 115 kV transmission line project consists of approximately 10.7 miles of new 115 kV transmission line stretching between a new Ponderosa substation located about eight miles west of Jal, New Mexico to a proposed Custer Mountain substation located nine miles northwest of Jal.

The project will provide new transmission capacity and electric service to the areas around the new Ponderosa substation and will improve service reliability in the area.

The Custer Mountain to Ponderosa 115 kV transmission line project went into service on May 25, 2017.

On April 29, 2014, the Southwest Power Pool approved the issuance of 44 Notices to Construct to Xcel Energy's Southwest Public Service Company for new transmission facilities in New Mexico needed between now and 2020 at a cost of $557 million. Xcel Energy plans to build all of the approved facilities including construction of 12 new substations and upgrades to nine existing substations, as well as 149 miles of new 115 kV and 245 miles of new 345 kV transmission lines.
