SunZia Transmission
New Mexico
Arizona
SunZia Transmission originates in east-central New Mexico. The new transmission line enables the development of the state’s high-quality wind resource for benefit across the western market. Torrance County is the eastern terminus of SunZia, which then traverses 353 miles southwest into Valencia, Socorro, Sierra, Grant, Luna, and Hidalgo counties before continuing its path through Arizona. The New Mexico portion of the line is being developed in partnership with the New Mexico Renewable Energy Transmission Authority (RETA), which facilitates the development of electric transmission and storage projects.
SunZia Transmission traverses over 199 miles in five Arizona counties, including Greenlee, Graham, Cochise, Pima, and Pinal before interconnecting with the Western Interconnection southeast of Phoenix. Access will enable development of new renewable resources to serve expanding renewable electricity demands.
