U.S. govt says Musk's gas turbine generators for xAI aren’t exempt from permits — EPA ruling closes local loophole that allowed Musk to get power from temporary on-site power generators

The U.S. Environmental Protection Agency has issued a ruling that eliminates permitting exemptions for gas turbine generators, impacting Elon Musk's xAI startup and others using this technology. Musk's company exploited a local loophole to quickly set up AI data centers with portable generators, bypassing the need for permits. However, the new rule mandates air permits for all gas turbines, including temporary ones, under the federal Clean Air Act. This change will affect companies relying on temporary power solutions for AI data centers due to grid connection delays, increasing regulatory requirements and eliminating local ordinance loopholes.
