Maine bans construction of data centers over 20 MW
Maine's legislature has passed a law instituting a 1.5-year moratorium on constructing data centers with a power capacity of 20 megawatts or more. The ban prevents municipalities and state agencies from accepting or issuing permits for such facilities until November 1, 2027; Governor Janet Mills has ten days to sign or veto the bill. During the moratorium a specially created council will study environmental impacts, grid reliability and consumer protections related to large data centers and advise future policy. The Data Center Coalition criticized the move as harmful to investment and jobs. The article notes the growing energy demand from AI workloads, citing an OpenAI metric for ChatGPT energy per request.
State-level moratorium on large data centers can constrain regional data center and AI infrastructure expansion, may affect investment decisions and set a regulatory precedent that other states could follow.

Massachusetts mandates clean power for large data centers
Massachusetts Governor Maura Healey has signed an executive order requiring data centers larger than 25 megawatts to supply their own clean power, either by generating it onsite, funding nearby clean generation, or paying into a ratepayer protection fund. This makes Massachusetts the third state in recent months to impose restrictions on data center development, following similar actions in Texas and New York. The order also pauses applications for a data center sales tax exemption and directs communities to avoid non-disclosure agreements. These measures reflect a growing public opposition to data centers and their energy demands, driven by the rise of AI. The tech industry is pushing back, with a pro-AI super PAC funded by prominent tech investors planning ad campaigns to sway voters in battleground states.
New York Halts New Data Center Construction
New York Governor Kathy Hochul signed an executive order temporarily barring the state from approving new permits for data centers that draw 50 megawatts or more, halting any unapproved projects while agencies complete an environmental review expected to take about a year. The Department of Environmental Conservation will not issue permits not already finalized. The Public Service Department is studying requirements for centers to fund dedicated clean generation and battery storage, and Hochul is weighing a grid-support fund and curbing tax breaks for hyperscale facilities; a separate Responsible Data Center Development Act in the legislature would impose a one-year pause for projects above 20 MW. Hochul also announced a reported Micron commitment of $100 billion and said she has agreements with the New York Power Authority to expand nuclear capacity; the move prompted both environmental praise and industry criticism.
Public Pushback Grows Against AI Data Center Expansion
Public opposition to large-scale AI data center construction is accelerating across the United States, driving local and state-level policy responses. A New York bill co-authored by State Senator Liz Krueger and Assemblymember Anna Kelles would impose a three-year moratorium on new data center permits statewide while communities study environmental and economic impacts. Numerous local moratoriums and restrictions have already passed in cities such as New Orleans and Madison, and lawmakers from both parties — including Florida Gov. Ron DeSantis, Sen. Bernie Sanders, and Arizona Gov. Katie Hobbs — have signaled support for limits or tax changes. Major tech firms (Amazon, Google, Meta, Microsoft, OpenAI) continue aggressive data center investment, while polling shows growing local opposition. Key concerns include grid strain, energy costs, water and pollution impacts, and tax-incentive debates; industry lobbying and mitigation pledges have begun but face political headwinds.
