Project Description

The proposed SunZia Southwest Transmission Project (Project) is composed of two planned 500-kilovolt transmission lines located across approximately 520 miles of Federal, state, and private lands between central New Mexico and central Arizona. The purpose of the Project is to transport up to 4,500 megawatts of primarily renewable energy from New Mexico to markets in Arizona and California. The permitted route originates at a planned substation in Torrance County, New Mexico, and terminates at the existing Pinal Central Substation in Pinal County, Arizona. The Project traverses Lincoln, Socorro, Sierra, Luna, Grant, Hidalgo, Valencia, and Torrance counties in New Mexico and Graham, Greenlee, Cochise, Pinal, and Pima counties in Arizona.
