The Battle Axe-Roadrunner 115 kV transmission line project consists of approximately 19 miles of new 115 kV transmission line between the Roadrunner substation located about 45 miles southeast of Carlsbad to the new Battle Axe substation located about 38 miles southeast of Carlsbad. The project includes the construction of the Battle Axe substation.
The project will provide new transmission capacity and electric service around the Battle Axe substation and will improve service reliability in the area.
The Battle Axe-Roadrunner 115 kV transmission line and substation was energized November 12, 2015. 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.
