Data Centers Are Driving an Alarming Gas Power Expansion in the US

Data Centers Are Driving an Alarming Gas Power Expansion in the US">

The amount of gas-fired power in development for data centers in the US has nearly doubled in less than a year, new research released Tuesday shows. The findings illustrate just how heavily tech companies are relying on building private fossil fuel plants to power data centers—and how fast artificial intelligence’s energy demand has grown.

Global Energy Monitor, a research firm, has been tracking gas-powered projects that have been announced, are in development, or are under construction in the US. In January, the group found that there were 97 gigawatts of gas projects in development exclusively for data centers at the end of 2025, a massive increase from just 4 gigawatts tracked in early 2024. Now, in an update to the research released Tuesday, the group says that as of mid-2026, that demand pipeline has jumped to more than 189 gigawatts. (A gigawatt can power roughly a million homes.)

“Increasingly, the US gas power buildout is getting tied directly to the data center buildout—you can’t talk about one without the other,” says Jenny Martos, a research analyst at Global Energy Monitor who worked on the report.

Over the past two years, data center builders have increasingly turned to private power facilities , known as behind-the-meter plants, to bypass lengthy grid connection times. This approach can also potentially help avoid saddling ratepayers with higher bills, an issue that’s become a flashpoint as data center opposition mounts around the country. The Trump administration has encouraged tech companies to bring their own power, introducing a voluntary pledge that’s been signed by the likes of Microsoft, Meta, Google, and OpenAI , as well as several Republican governors and some of the country’s biggest utilities.

Adding that much natural gas power comes with a hefty climate cost, particularly because many of the facilities are being built with inefficient turbines , which can increase emissions. As WIRED has reported , some of these gas plants are permitted to emit more greenhouse gases each year than many small- and medium-sized countries.

Global Energy Monitor also tracks energy projects in countries around the world, including China, the world’s largest importer of natural gas. Much of that gas is used for producing products like fertilizer and plastic.

But the country does have a modest fleet of natural gas plants, and it’s seen a surge in gas-fired facilities under development in recent years. In the early 2020s, it even outpaced the US in gas plant construction. The data center boom means that the US has again surpassed China as the country with the most gas projects in the pipeline, according to Global Energy Monitor.
