Maine Governor Janet Mills vetoed LD 307 Friday, the bill that would have created the first statewide moratorium on large AI data centers in the United States. The legislation, which had passed both chambers of the state Legislature, would have blocked state and local permits for data centers drawing 20 megawatts or more until November 2027, creating space for a study of regional impacts. Mills's veto rested on a specific carveout that the bill did not include: a project at the former Androscoggin Mill in Jay, Maine. The mill closed in 2023, costing several hundred paper-industry jobs in a region with limited alternatives. The proposed data center on the site would generate more than 800 construction jobs, at least 100 high-paying permanent jobs, and substantial property tax revenue for the town. Mills said she would have signed the bill with that exemption included.
The political shape of the veto matters. Mills explicitly endorsed the policy direction, writing that "given the serious conversations about data centers here and around the country, I believe this work should commence without delay." She announced an executive order creating a study council to examine large-scale data center impacts in Maine. The veto was therefore not ideological opposition to moratoria; it was tactical preservation of a specific job-creation project in a region where data center capacity is materially competing with the loss of legacy industry. That is the realistic political dynamic for any data center siting moratorium proposal across the US: jurisdictions facing rural or post-industrial economic decline see data center investment as a viable replacement, and any clean ban without surgical carveouts will hit local opposition the moment a specific project gets attached to it.
The broader picture from yesterday's data-colonialism coverage by Honor the Earth and the Maine action together is that data center siting is now a live political question at multiple levels of US government. Tribal nations have moved first with moratoria on tribal lands. State-level moratoria are being introduced and, as Maine demonstrates, are not guaranteed to pass even when legislatures support them. Federal action is unlikely under the current administration but possible under a future one. The Tulsa nine-month moratorium and Seminole Nation moratorium I wrote about earlier remain in effect; Maine's would have been the first state-wide example. The fact that a Democratic governor vetoed it for a specific project tells you something about how narrow the political coalition for blanket moratoria is. The coalition for project-specific scrutiny is broader.
For builders and operators, the practical implication is that data center siting decisions are entering an extended period of jurisdictional uncertainty. If your business depends on inference capacity coming online over the next two to four years, the geography of where new builds are permitted is going to vary materially by state, county, and tribal sovereignty. Project-by-project political negotiation is the new norm. The Maine outcome suggests one workable pattern: governors will trade their veto for jobs commitments and tax revenue concessions, but they want the option to say no to projects without a clear local economic case. If you are siting a large data center in a state that has any kind of moratorium discussion underway, the differential between a project that brings construction and permanent jobs to a depressed region versus one that brings limited employment but heavy water and grid demand is going to be the decisive variable. The economics nobody is willing to talk about openly are that even with all the controversy, large-scale data centers offer one of the few credible economic-development plays available to rural and post-industrial communities. That tension is going to drive the next year of policy.
