Amazon backs a 7.65 GW gas plant for an off-grid Texas AI campus
The AI power arms race just crossed a new line: Amazon is behind what could become the largest fossil-fuel power plant ever built in the US, and it exists for one customer — Amazon's own AI data centers.
Amazon has confirmed it acquired GW Ranch, a site in Pecos County, West Texas, where it plans to build a 7.65-gigawatt natural gas plant to power its first off-grid AI data center campus — a project that state permits suggest could become the single largest source of emissions in the country. The plant, developed by Pacifico Energy, would run 35 gas turbines and, at least initially, sit entirely outside the Texas electricity grid. Cleanview, the market intelligence firm that broke the story Friday, connected the plant to three data center construction permits Amazon filed with the state this week; satellite imagery already shows land clearing underway.
The emissions math is the headline. The Texas permit would allow the plant to release roughly 33 million tons of carbon dioxide per year — more than the country's biggest coal plant, and enough to make GW Ranch the largest single pollution site in the US, according to Cleanview's analysis of the permits. That sits in direct tension with Amazon's Climate Pledge commitment to reach net-zero emissions by 2040, a target the company reiterated in response to the reporting while pointing to the 10 GW of carbon-free energy it says it has enabled across 40 Texas projects for its existing data center operations.
Amazon is not the first hyperscaler to go behind the meter — Microsoft, Google, Meta and xAI have all made off-grid gas moves this year, including Microsoft's Chevron-backed 2 GW campus about 30 miles west of GW Ranch. But the scale is the story. Cleanview counts nearly 60 behind-the-meter gas projects announced since the start of 2025, totaling roughly 90 GW of capacity that could emit more than 200 million tons of CO2 a year if fully built. Amazon's water plan — non-potable brackish groundwater that can't be used for irrigation or drinking — and Pacifico's proposed 750 MW of on-site solar and 1.8 GW of battery storage soften the edges without changing the core: the AI buildout is now financing its own fossil generation.
The deeper question is what this does to the climate accounting big tech has leaned on. Off-grid plants like GW Ranch sit outside the grid, which makes their emissions harder to attribute in the usual utility accounting — yet they are the most direct emissions the companies have ever signed up for. If this project is built as permitted, Amazon's net-zero pledge stops being a trajectory and becomes a contradiction measured in megatons.
What to watch: whether Texas regulators and local opposition slow the permits, and how Amazon squares GW Ranch with the climate accounting in its next sustainability report.
If off-grid AI power plants never show up on any grid's books, should they still count against Amazon's net-zero pledge? Tell us in the comments.
