One of the largest solar projects in the U.S. opened in Texas on Friday, backed by what Google said is the largest solar electricity purchase it has ever made.

Google executive Ben Sloss said at the ribbon cutting, about two hours south of Dallas, that the corporation has a responsibility to bring renewable, carbon-free electricity online at the same time it opens operations that will use that power. Google expects to spend $16 billion through 2040 globally to purchase clean energy, he said.

U.S. Energy Secretary Jennifer Granholm, who attended, said the solar project is a posterchild for the administration’s efforts to incentivize manufacturers and developers to locate energy projects in the U.S.

“Sometimes when you are in the middle of history, it’s hard to tell, because you are in the middle of it,” she said. “But I’m telling you right now that we are in the middle of history being made.”

SB Energy built three solar farms side by side, the “Orion Solar Belt,” in Buckholts, Texas. Combined, they will be able to provide 875 megawatts of clean energy. That is nearly the size of a typical nuclear facility. In total, Google has contracted with clean energy developers to bring more than 2,800 megawatts of new wind and solar projects to the state, which it says exceeds the amount of power required for its operations there.

Google, Amazon and Microsoft have all recently announced investments in nuclear energy to power data centers, too, as the tech giants seek new sources of carbon-free electricity to meet surging demand from data centers and artificial intelligence. Google has a commitment to get all of its electricity without contributing to climate change, regardless of time of day or whether the sun is up, but neither it nor other large companies are meeting those commitments with the rise of artificial intelligence.

The International Energy Agency forecasts that data centers’ total electricity consumption could reach more than 1,000 terawatt-hours in 2026, more than doubling from 2022. Estimates suggest one terawatt-hour can power 70,000 homes for a year.

The demand for power is also growing globally as buildings and vehicles electrify. People used more electricity than ever last year, placing strain on electric grids around the world.

In August, Google said it planned to invest more than $1 billion in Texas this year to support its cloud and data center infrastructure.

Google will use about 85% of the project’s solar power for data centers in Ellis County and for cloud computing in the Dallas region. In Ellis County, Google operates a data center campus in Midlothian and is building out a new campus in Red Oak. The rest of the solar power will go to the state’s electrical grid. Thousands of sheep graze in the area, maintaining the vegetation around the solar arrays.

“This project was a spreadsheet and a set of emails that I had been exchanging and a bunch of approvals and so on. And then you come over the rise over there and you see it laid out in front of you and it kind of takes your breath away, right? Because there’s this enormous field of solar arrays,” Sloss said during the ceremony. “And we actually collectively have done this. That is amazing.”

SB Energy said most of the solar farm components are made in the United States, and that’s only possible because the climate law formally known as the Inflation Reduction Act spurred clean energy manufacturing. The company expects the projects to be the first to qualify for an extra tax credit the law affords for using domestic content.
