Why are communities fighting AI data centers, and what is a moratorium?

Residents mainly object to higher power bills, water use, noise, air pollution and secrecy, while supporters point to tax revenue, construction work and national competition in AI. A moratorium is a temporary legal pause on approvals, and in 2026 New York became the first US state to impose one, for sites of 50 megawatts or more.

Why are communities fighting AI data centers, and what is a…

Data centers used to be quiet background infrastructure. In 2026 they became an election issue. A Heatmap poll reported by CNBC found that seven in 10 Americans would oppose a data center near them, up from four in 10 in August of the previous year. In Lysander, a town near Syracuse, New York, more than 350 residents came to the monthly town board meeting in May, and the board unanimously approved a six-month pause.

The shift has real causes, and supporters of these projects have real arguments too. Here is what each side says, and what the law has done so far.

What people object to, and what supporters answer

Concern	The objection	The reply
Power bills	New demand raises costs for everyone; PJM's market monitor attributes 40% of one auction's cost to data centers	Companies say they will pay their full costs; Entergy projects savings for its customers from Meta's deal
Water	Cooling can draw on local supplies	Many new designs use closed loops, at a cost in electricity
Air and noise	On-site gas turbines and cooling fans affect neighbors	Regulators have approved some of this equipment, such as Mississippi's permit for 41 turbines at xAI's site
Jobs and money	Few permanent jobs for the size of the site	Meta counts 7,500 construction jobs at peak and 1,000 permanent roles in Louisiana, and over $1.6 billion in contracts with state businesses
Secrecy	Deals negotiated behind closed doors	New York's bill would have required public hearings and disclosure of projected energy use
Strategy	Why should one town bear the burden?	Supporters, including President Trump, frame the sites as engines of jobs and growth

The last row of the table is the hardest to settle. The costs are local, while many of the benefits are national or global. That is why these fights tend to appear at town council level.

What a moratorium does, and does not do

A moratorium is a temporary pause on approvals, normally while a government studies a question or writes rules. It does not ban data centers forever, and it usually does not shut down what is already operating.

The size threshold decides how much it covers. A Rockefeller Institute review found that 14 states had considered a state moratorium by June 2026, with thresholds as low as 1 megawatt in a Virginia bill and as high as 100 in several others. Most of those bills had only been introduced.

The two state cases to know

Maine. The legislature passed the first state moratorium, covering data centers above 20 megawatts until November 2027. Governor Janet Mills vetoed it on April 24, 2026. She said she supported a pause but wanted an exemption for a project at a former mill in the town of Jay.

New York. On June 4, 2026, the legislature passed a one-year pause for sites of 20 megawatts or more. Rather than act on that bill, Governor Kathy Hochul signed Executive Order 62 on July 14. The two differ in important ways:

	Legislature's bill	Executive Order 62
Threshold	20 MW	50 MW
Status	Governor has until year end to sign or veto	In force
End point	One year	When a state environmental study is finished
Local permits	State permits only	Does not cover local approvals

The order excludes facilities used mainly for manufacturing, research, education or medical care, which leaves room for projects such as the Empire AI university consortium. It cites nearly 12 gigawatts of data center requests in the state's grid queue. President Trump criticized it, while a Siena poll in August found voters in favor by two to one. The Tech:NYC trade group said it prefers her approach to the legislature's stricter bill.

Towns act first

Local governments can often move faster than states. The Rockefeller review lists moratoriums or bans in places such as Groton, Connecticut; Peculiar, Missouri; and Bangor, Maine. In New York, Oneonta passed a one-year pause in May in response to a proposal to rezone farmland.

Project maps can also change. Epoch AI, a research group that tracks AI sites, mentions a ban on future data centers in Lordstown, Ohio, and local opposition to the Stargate site in Michigan.

Canada takes a different route

Canadian provinces own or closely regulate much of their electricity, so the main tool is who gets power, at what price. There is no New York-style pause, and Hydro-Québec told its regulator that its proposed data center rate is "clearly not a moratorium" (our translation).

The result can still limit growth. Québec requires ministerial authorization to supply a data center of 5 megawatts or more, and BC Hydro can only award 300 megawatts for AI in its first two-year window, weighing criteria such as data sovereignty and First Nations benefits. See our article on power grids for details.

Try it: Search your municipality's or MRC's recent council minutes for "data center" or "centre de données". Note the size of the project, the zoning change requested and the date of the next public meeting.

What can residents actually do when a data center is proposed nearby?

Get the specifics in writing. Useful questions to ask at a public meeting are shown here, and an assistant can help you turn a long filing into a list of them:

Prompt

Here is a planning document for a proposed data center. Using only this document, list:
1. Its peak electricity demand in megawatts, and who supplies it.
2. Its cooling method and expected water use, including peak days.
3. Any on-site generators or turbines, and the permits they need.
4. Noise limits and where they are measured.
5. Jobs promised, tax arrangements and who enforces them.
Quote the page for each answer and write "not stated" when the document does not say.

Then use the formal steps: comment during public consultations, ask for permit documents through access-to-information requests, and check which government has the actual authority, because a town, a province or state and a utility regulator may each decide a different part. In New York, for example, the state order leaves local approvals untouched. Going to the right body early usually matters more than a large turnout at the final vote.
