Maine Just Became the First State to Ban Data Center Construction

Last updated: April 2026

Maine became the first U.S. state to impose a moratorium on data center construction, passing a bill that blocks new facilities using more than 20 megawatts of power until November 2027 and creates a study council to assess impacts on energy prices, the grid, and local communities. The 18-month moratorium is the first law of its kind in the United States.

The bill passed with bipartisan support despite fierce opposition from the tech industry and business groups. Governor Janet Mills, who is currently running for U.S. Senate, has not yet signed it. She requested an exemption for several areas where construction could continue. The House rejected that amendment 115 to 29.

Why Maine, Why Now

Maine has some of the highest electricity rates in the country. The state has not attracted a major data center project, but smaller facilities are in early stages. Legislators saw what is happening in Virginia, Georgia, Texas, and Mississippi, where data center construction is driving up electricity costs for residential customers, straining the grid, and generating community opposition. In Memphis, the NAACP just sued xAI for running 27 unpermitted gas turbines to power its Colossus 2 data center — the exact kind of unchecked buildout that Maine legislators wanted to prevent. They decided to get ahead of it.

Seth Berry, executive director of Our Power (a Maine-based energy nonprofit), put the rationale plainly: if data centers are allowed to increase energy costs in a state where residents already pay top-dollar rates, lower and working-class populations get hurt first. Even when data center developers promise to build their own power supply, the net effect on electricity pricing is still negative for existing ratepayers.

The moratorium creates breathing room. The state gets 18 months to study how data centers affect energy markets, develop permitting standards, and figure out whether the economic benefits (jobs, tax revenue) actually offset the costs (grid strain, higher bills, environmental impact). That is a rational approach to a fast-moving industry that most states have been approving without analysis.

The Business Pushback

The tech industry’s objection is predictable and, to some degree, valid. Glenn Adams, business development director for Maine-based construction firm Sargent Corp., argued that any state putting a pause on data centers will fall behind. “Things are going so fast. There’s a race against other countries,” he said. “If Maine says ‘no,’ we’re saying no to all these companies.”

Patrick Woodcock, president and CEO of the Maine State Chamber of Commerce, argued that existing permitting processes are sufficient and that more companies paying for electricity would actually reduce costs for homeowners. His position is that a moratorium is overkill when regulatory review could accomplish the same goal.

These are reasonable arguments. They are also arguments that every extractive industry has made in every state, in every decade, when regulation was proposed. The data center industry is not entitled to build wherever it wants, on whatever timeline it prefers, using whatever amount of electricity it needs, without the host community having a say.

This Is About to Spread

Maine is first. It will not be last. Bills proposing data center moratoriums have been introduced in at least a dozen states, including Virginia and Georgia (two of the biggest data center markets in the country). Georgia’s legislature adjourned before acting on its bill. Virginia’s is still pending.

The dynamic is consistent across states: communities are realizing that data centers produce very few jobs relative to their size, consume enormous amounts of electricity and water, and often receive generous tax incentives that reduce their contributions to local budgets. The EU’s AI Act logging requirements are already forcing infrastructure transparency that makes these calculations harder to hide. The AI boom has accelerated all of these concerns because AI workloads require significantly more power per rack than traditional cloud computing. Meta alone plans to spend $115–135 billion on AI infrastructure in 2026 — that capital has to land somewhere physical, and communities are increasingly saying “not here.”

For the legal and business community, this creates a new category of regulatory risk. Data center developers can no longer assume that building permits will be available on their preferred timeline. Lease agreements, power purchase agreements, and construction contracts all need to account for the possibility that a moratorium could delay or block a project mid-development.

What to Do Now

If you are developing or financing data centers, add moratorium risk to your due diligence. Check whether the target state or municipality has pending legislation, ballot measures, or community opposition that could result in construction delays. Maine’s bill went from introduction to passage faster than most development timelines.

If you are advising municipalities on data center deals, push for independent analysis of energy impact, water usage, and actual job creation before approving tax incentives or zoning changes. The deals that look good on a press release often look different in a rate case two years later.

This is part of the broader AI regulatory patchwork — infrastructure regulation is now as fragmented and unpredictable as AI product regulation.

If you are a general counsel at a company that depends on data center capacity, diversify your infrastructure planning. Concentration risk now includes regulatory risk. A single-state data center strategy is more fragile than it was six months ago. The California Chamber’s anti-AI bills push signals that even business-friendly lobbies are losing patience with unchecked AI infrastructure expansion.

The broader question is whether the AI industry’s demand for compute will outrun the public’s willingness to host it. Maine’s answer, at least for the next 18 months, is clear: slow down, study the problem, and let the people who live here decide whether the tradeoffs are worth it. Other states are watching.
