Summary
Pattern Energy said SunZia has reached commercial operation on schedule and within budget, completing an 18-year effort to bring 3,650 megawatts of New Mexico wind onto the western U.S. grid.
The project pairs that wind capacity with a 550-mile HVDC transmission line, designed to move power long distances with lower losses and ease a major bottleneck in getting new electricity supplies to market.
At full capacity, SunZia is expected to supply about 1 million homes a year as western power demand rises from population growth, industrial expansion, electrification and data-center buildouts.
More than 2,000 workers were employed at peak construction, and Pattern estimates over $20 billion in regional investment plus about $1.3 billion in payments to local governments, schools, counties and landowners over 30 years.
SunZia joins a broader wave of U.S. transmission buildouts aimed at linking renewable-rich regions with demand centers, highlighting grid expansion as central to long-term energy growth.

SunZia Wind and Transmission: Launching 3.5 GW of Clean Power and 550 Miles of HVDC—Economic, Legal, and Environmental Impacts of the Largest U.S. Renewable Project
Overview
The SunZia Wind and Transmission project, launched in mid-2026, marks a major milestone as the largest clean energy infrastructure project in U.S. history. With an investment of over $16 billion, SunZia combines more than 3,500 megawatts of new wind capacity and a 550-mile transmission line, delivering a significant boost to electricity supplies across the Western U.S. This integration of large-scale wind generation and extensive transmission infrastructure not only strengthens the grid but also brings substantial economic benefits, with expected impacts reaching $20.5 billion, and positions New Mexico as a leader in renewable energy capacity.
