More About This Project:

The SunZia Wind and Transmission project integrates large-scale wind generation with long-distance transmission infrastructure to deliver renewable power across the Southwest. The project includes 916 turbines across two wind facilities in New Mexico — SunZia Wind North and SunZia Wind South — totalling 3,515 MW of installed capacity. Supporting infrastructure includes hundreds of miles of collection systems, access roads, gen-tie lines, and substations, along with massive material requirements including over 450,000 tons of steel and more than 530,000 cubic yards of concrete.

Power generated by the wind facilities is transmitted through a 551-mile, 525 kV HVDC transmission system connecting New Mexico to Arizona. The system includes major east and west converter stations, approximately 2,162 transmission structures, and more than 30 million linear feet of conductor — equivalent to over 5,700 miles of overhead transmission cable. Once operational, the system will provide 3,000 MW of active transmission capacity, delivering renewable power to growing energy markets across Arizona, California, and the broader Southwest.

Executing a project of this scale requires an enormous workforce and careful environmental stewardship. At peak construction, the project employs more than 2,500 workers and involves the relocation of approximately 15,000 saguaro cacti to protect sensitive desert ecosystems. Through its scale, engineering complexity, and integrated generation-to-transmission design, SunZia is setting a new standard for renewable infrastructure while strengthening the clean energy backbone of the American Southwest.

Supported by InEight:

Pattern Energy used the InEight platform to manage document and project controls across the SunZia Wind and Transmission project. Through InEight Document, the team centralised project records including drawings, RFIs, transmittals, and technical submissions across multiple project scopes. Over the course of the project, 146 users managed more than 200,000 documents, helping standardise naming conventions, metadata, and document workflows to improve transparency and coordination. Following the success of SunZia, Pattern has expanded its use of the InEight platform across its portfolio of complex renewable energy projects.
