Incident 1677: xAI Reportedly Operated Unpermitted Gas Turbines in Southaven, Mississippi, to Power Colossus 2 AI Data Center, Producing Air Pollution and Noise

Responded

Description: Beginning August 1, 2025, xAI reportedly began installing and later operating gas turbines in Southaven, Mississippi, to power its Colossus 2 AI data center in Memphis. 57 turbines were later reportedly identified at the site, while residents described persistent noise in nearby neighborhoods. Civil-rights groups allege the turbines required Clean Air Act permits and added harmful pollution near predominantly Black communities; Mississippi regulators maintain the temporary turbines did not require air permits.

Variants

A "variant" is an AI incident similar to a known case—it has the same causes, harms, and AI system. Instead of listing it separately, we group it under the first reported incident. Unlike other incidents, variants do not need to have been reported outside the AIID. Learn more from the research paper.
