xAI Allegedly Operates Unpermitted Methane Turbines in Memphis to Power Supercomputer Colossus to Train Grok

Open on the AI Incident Database 9 news reports Snapshot 7 Sep 2026

What happened

The xAI "Colossus" supercomputer facility in South Memphis allegedly runs 33 methane-powered turbines, despite a permit for only 15. The turbines reportedly power AI training for Grok. The facility's massive energy use and alleged unpermitted turbines reportedly produce extreme nitrogen oxide and formaldehyde emissions, adding toxic smog to a predominantly Black neighborhood already burdened by pollution and health risks.
