State regulators approved a project planned by Tucson-based UniSource Energy Services and a Texas company to upgrade a high-voltage transmission line between Vail and Nogales, and related construction of a new power line from Nogales to Mexico.

The Arizona Corporation Commission voted unanimously Tuesday to approve both the Vail-Nogales project, which is backed by UES Electric, part of UNS Energy Corp. that serves Santa Cruz and Mohave counties, and the Nogales-Mexico line planned by Dallas-based Hunt Power.

The project was granted a required certificate of environmental compatibility by the Arizona Power Plant and Transmission Line Siting Committee in late September, after public-comment meetings in Nogales and Tucson.
