EPA exempts data center power plants from pollution limits seeking to prevent acid rain
The guidance could speed AI infrastructure development and reduce pressure on regional power grids, the EPA said.
- On Monday, the Environmental Protection Agency announced that power plants serving data centers unconnected to the electric grid fall outside the Clean Air Act's Acid Rain Program, as these "islanded" units neither sell electricity nor require Department of Energy reporting.
- This guidance supports President Donald Trump's Ratepayer Protection Pledge, which requires companies to "build, bring, or buy" all power generation resources, aiming to accelerate AI-related infrastructure development and ease strain on regional power grids.
- EPA Assistant Administrator Aaron Szabo clarified in a July 16 letter that 1990 Clean Air Act amendments apply only to plants selling electricity, stating the policy ensures the United States maintains artificial intelligence dominance while safeguarding communities from utility price hikes.
- Environmental groups, including the Environmental Defense Fund and Natural Resources Defense Council, have challenged EPA actions, citing concerns over public health and alleging that gas turbines were operated near Memphis in April before securing required local air permits.
- A 2026 report by Bloom Energy found that on-site power is increasingly part of future data center strategies due to grid constraints, with more than one-third of data centers expected to use 100 percent on-site power by 2030.

EPA: Off-grid data centers not subject to Acid Rain Program
(The Center Square) – The U.S. Environmental Protection Agency announced Monday it has determined that the power generation plants of data centers unconnected to the electric grid fall outside the scope of the Clean Air Act’s Acid Rain Program.
EPA Says Some Data Center Power Generators Not Subject to Program Under Clean Air Act
The Environmental Protection Agency (EPA) said in a press statement on Monday that certain off-grid, or “islanded,” electricity generators are not subject to the federal Acid Rain Program under the Clean Air Act. The statement outlines a clarification that the EPA earlier issued to regional administrators addressing generating units that produce electricity solely for on-site use and are not connected to the electric grid. “The EPA believes tha…

Times of IndiaUS agency says power for data centers can sidestep pollution laws
The U.S. Environmental Protection Agency (EPA) has said power plants built exclusively to supply electricity to data centers, and not connected to the public grid, may be exempt from key federal pollution rules. The move is aimed at accelerating AI infrastructure development, easing pressure on regional power grids, and supporting the rapid expansion of data centers across the United States.
