Congressional moratorium on AI data centers
Sen. Bernie Sanders and Rep. Alexandria Ocasio‑Cortez introduced a bill proposing a moratorium on new AI data centers until national safeguards on water, climate impact, and community disruption are in place. The proposal elevates regulatory risk for rapid capacity expansion and means infrastructure planning will need to factor in potential near‑term permitting constraints.

The measure is formally titled the “Artificial Intelligence Data Center Moratorium Act” and the Senate filing and companion materials were released on March 25, 2026 (sanders.senate.gov). (sanders.senate.gov) The bill text and section‑by‑section memo define an “AI data center” as facilities used for large‑scale model development or that have a total peak power load in excess of 20 megawatts and that employ high‑performance server racks or liquid‑cooling systems (sanders.senate.gov). (sanders.senate.gov) The statutory moratorium language would halt approval and construction of covered facilities “until legislation is enacted” that requires government pre‑release safety reviews of AI systems, protections against mass job displacement, and limits on utility‑price impacts tied to data‑center growth (thehill.com). (thehill.com) The sponsors’ press release also includes a ban on exporting U.S. AI computing infrastructure to countries that lack comparable safeguards, and it notes that “more than 100” local moratoriums and proposals in “12 states” have already been pursued at the municipal and state level (sanders.senate.gov). (sanders.senate.gov) The bill lands as hyperscale cloud providers and tech giants continue to commit multi‑billion‑dollar data‑center buildouts to support AI workloads, a dynamic Bloomberg Government and others say is accelerating regional projects and transmission upgrades (bloomberg.com). (news.bgov.com) Legal and political analysts warn the proposal faces long odds in the current Congress, with multiple outlets reporting the measure is unlikely to advance quickly even as state proposals such as New York’s S.9144 (a proposed statewide moratorium on ≥20 MW facilities) gain traction (apnews.com; dlapiper.com).
