Andrews-NEF 115 kV Transmission Line Project

The Andrews-NEF 115 kV transmission line project was placed in-service on April 22, 2016.

The Andrews-National Enrichment Facility (NEF) 115 kV transmission line project consists of approximately two miles of new 115 kV transmission line between the Andrews substation on the Texas border, approximately seven miles from Eunice, New Mexico, to the NEF substation located five miles southeast of Eunice, New Mexico. This project will also includes the installation of a 230/115kV transformer and associated equipment in the Andrews substation.

The project provides an additional source of power to the NEF substation as well as additional 115kV transmission capacity to the 115 kV system in the area. The estimated cost of the project is $14 million.

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.
