How the biggest renewable energy project in US history finally got built

The SunZia wind farm is a marvel. Why did it take 20 years to build?

When the sun goes down, the wind picks up in central New Mexico, whipping through arid canyons with a ghostly howl that for centuries, locals have likened to the wails of the folkloric ghost La Llorona.

A few hours east of Albuquerque, this June, those gusts began powering the largest wind farm this continent has ever seen, twirling over 900 colossal steel turbines. Each is as tall as the Statue of Liberty, scattered across a patch of desert roughly the size of Chicago. They plug into a 550-mile transmission line stitched across the Southwest and are now powering over one million homes — as far away as California.

The SunZia Wind and Transmission project is a rare 21st-century triumph of American infrastructure, an engineering marvel that generates more electricity than the Hoover Dam. When the turbines came online this spring, they immediately broke records for wind-generated power in California’s energy supply, where solar power may rule the day, but the winds of New Mexico increasingly fuel the night.

SunZia, the largest clean energy megaproject in US history, finally came online this June, sending New Mexico wind power to customers in Arizona and California.

For over a decade and a half, the project was delayed by permitting issues, lawsuits, and above all, an energy market that wasn’t ready for the power it had to offer.

With the nation’s electricity demand skyrocketing, SunZia’s collaboration with conservationists may offer a blueprint for getting more megaprojects built.

After years of stagnant power growth, the US is absolutely starving for more electricity, with demand projected to rise by 25 percent by the end of this decade, and a staggering 78 percent by 2050. Enormous as this challenge might seem, it may ultimately be the catalyst the country needs to dramatically dial up its renewable energy infrastructure, so that the years to come are powered not by gas or coal, but by clean energy sources like the sun and the wind. By next summer, the project will have prevented about 9 million metric tons of carbon dioxide from entering the atmosphere, according to Pattern Energy, the project’s developer.

For decades, however, it seemed the project would remain little more than a spectral dream.

“It works!” This was the call Hunter Armistead, Pattern’s CEO, remembers getting from his head engineer when the turbines came online for the very first time. “We were creating power, and it was showing up 550 miles away in Phoenix, almost as if it was magic.” During the ribbon-cutting for the wind farm, some construction workers showed off massive new turbine tattoos. “It’s their pride that for the rest of their lives, they can drive by and tell their kid, ‘I did this,’” Armistead said.

But SunZia almost didn’t get built at all. It is not just the project’s scale that makes it remarkable, but the utter morass its developers slogged through to bring it online. The project spanned five presidential administrations, an ownership change, a major reroute, and a standoff with a US military base.
