Pattern Energy’s SunZia wind farm<\/strong> in central New Mexico entered commercial operations in June 2026, becoming the largest wind farm in the United States at 3,650 megawatts<\/strong> of net summer generating capacity.<\/p>\n

The wind facility and its 550-mile transmission line began delivering power to Arizona and California in June 2026, after nearly two decades of development.<\/p>\n

The project comprises 916 wind turbines spread across three counties in central New Mexico: San Miguel, Lincoln, and Torrance.<\/p>\n

That capacity is more than three times larger than the next two biggest wind farms in the country, Alta Wind in Southern California at 1,098 MW and Great Prairie in northern Texas at 1,027 MW.<\/p>\n

How the turbines and layout are organized<\/h2>\n

The project features a mix of turbines from GE Vernova<\/strong> and Vestas.<\/p>\n

GE Vernova supplied 674 turbines, roughly 2.4 GW of generating capacity, marking the largest single onshore wind turbine order in the company’s history.<\/p>\n

Vestas installed 242 V163-4.5 MW turbines, accounting for the remaining 1.1 GW of capacity.<\/p>\n

Pattern chose two suppliers to manage risk given the project’s scale.<\/p>\n

The complex also includes 10 collection substations, 115 miles of overhead collection lines, and 130 miles of 345 kV AC generation tie lines.<\/p>\n

That overhead electrical network links hundreds of individual turbines into a single coordinated generating system<\/strong> before power reaches the export line.<\/p>\n

The 550-mile transmission line that carries the power west<\/h2>\n

Getting the power to market required a companion project: the SunZia Transmission Project, a 550-mile high voltage direct current line running from central New Mexico to south-central Arizona.<\/p>\n

High voltage direct current, or HVDC, transmission loses less energy over long distances than conventional alternating current lines, making it the standard choice for moving large amounts of power across hundreds of miles.<\/p>\n

Of the line’s 3,021 MW of total capacity, 2,131 MW<\/strong> will be delivered to Southern California via the Palo Verde Substation.<\/p>\n

California Community Choice Aggregators have contracted approximately 1.85 GW of SunZia’s output, including Ava Community Energy, Central Coast Community Energy, Silicon Valley Clean Energy, and the San Francisco Public Utilities Commission.<\/p>\n

Pattern Energy has also announced a power agreement with Salt River Project, a not-for-profit public utility in Arizona.<\/p>\n

What the project’s scale means for the western grid<\/h2>\n

With SunZia operational, wind generating capacity in New Mexico jumps from roughly 4,000 MW to approximately 7,647 MW.<\/p>\n

Wind will represent 45 percent of the state’s total capacity mix, ahead of solar at 19 percent and natural gas at 19 percent.<\/p>\n

On May 15, 2026, the California Independent System Operator logged 7,122 MW of hourly wind generation, 20 percent above the prior annual record, with SunZia turbines contributing during a pre-commercial testing phase.<\/p>\n

At full capacity SunZia can deliver more power than the Hoover Dam, according to Pattern Energy.<\/p>\n

The power flows into markets where electricity demand has been climbing, driven partly by data center construction<\/strong> and industrial expansion across California and Arizona.<\/p>\n

The project is also designed to contribute an estimated $20.5 billion<\/strong> to the national economy.<\/p>\n

Construction timeline and what was built on the ground<\/h2>\n

The groundbreaking ceremony was held in September 2023 for the transmission line component of the project.<\/p>\n

The total project cost, including the transmission line, reached approximately $11 billion, according to Pattern Energy<\/a>.<\/p>\n

Turbine commissioning began in April 2026, with testing of the 916 units proceeding through spring before the transition to commercial operations.<\/p>\n

The project is expected to create over 2,000 jobs during peak construction and more than 100 permanent jobs upon operation.<\/p>\n

Each turbine typically requires around one acre of land after construction, allowing landowners to continue farming and ranching around them.<\/p>\n

That arrangement means the three county footprint in New Mexico continues to support livestock grazing and agricultural use alongside the turbine rows.<\/p>\n

Once turbines wear out, recycling what comes down is a growing concern for the industry.<\/p>\n

A turbine blade can run beyond 170 feet, and a Tennessee company now bakes worn blades down to recover the clean glass fiber the industry once paid to bury.<\/p>\n

Limits, uncertainties and what comes next<\/h2>\n

SunZia’s debut comes while the broader US wind sector faces a divided outlook.<\/p>\n

Land-based wind projects saw gains globally in 2025, with the onshore pipeline in the US remaining active.<\/p>\n

In the US, the onshore development pipeline continues to grow, per EIA data.<\/p>\n

Offshore wind faces more pressure, with forecasters citing the removal of federal tax credits and stricter permitting on federal land as headwinds for US renewable capacity growth.<\/p>\n

SunZia itself took almost two decades of permitting before a shovel entered the ground, a reminder that even approved projects carry long lead times.<\/p>\n

Pattern Energy has not announced a firm timeline for any expansion at the New Mexico site.<\/p>\n

The offtake contracts underpinning the project’s economics remain spread across multiple California and Arizona buyers rather than a single utility, which distributes revenue risk but adds commercial complexity.<\/p>\n
