Maine is on the verge of enacting legislation that would make it the first state in the United States to freeze new large-scale data center construction — a significant regulatory move driven by community backlash over energy consumption, water use, and local opposition that has already killed several proposed multi-billion-dollar facilities in the state. The bill, LD 307, would block state and local governments from issuing permits or approvals for data centers with electric loads of 20 megawatts or more until a newly created study council completes its assessment, with the moratorium running through at least late 2027.
The Wall Street Journal described Maine as "poised to freeze large data-center construction, which would make it the first state to enact such a measure as communities across the U.S." grapple with the industry's rapid expansion. The legislation, which advanced through Maine's legislature in early March 2026, reflects a broader national tension between AI infrastructure demand and local communities increasingly unwilling to absorb the costs.
What LD 307 Does
The bill was sponsored by state Representative Melanie Sachs, a Democrat from Freeport, Maine. During a work session of the legislature's Energy, Utilities and Technology Committee on February 12, 2026, Sachs proposed adding an amendment to establish a moratorium on data centers using 20 megawatts or more of power, according to The Maine Monitor.
Under the terms of LD 307 as advanced, state agencies, local governments, and quasi-governmental bodies would be prohibited from granting permits, approvals, or other authorizations for large data center facilities until 90 days after a newly formed data center coordination council submits its findings to the legislature. The Boston Globe reported the amendment would pause construction until July 1, 2028, while Maine Public Radio reported a separate tax provision: a companion measure would exclude data centers from Maine's Business Equipment Tax Exemption (BETE) program, which provides a 100% break on eligible property.
The legislation does not affect facilities already operating or those below the 20-megawatt threshold.
Why Maine, Why Now
Maine currently has no operating large-scale data centers and none under active construction — a fact that cuts both ways in the political debate. Proponents of the moratorium argue the state has a rare opportunity to pause and plan before being overwhelmed by an industry expanding too fast for communities to absorb. Opponents counter that the legislation would freeze a nascent economic opportunity before it materializes.
The backdrop is a string of high-profile proposed projects that collapsed under local resistance. A $5 billion facility proposed for Wiscasset and a $300 million center in Lewiston both stalled after pushback from residents caused local governments to withdraw from negotiations with developers, according to the Bangor Daily News. The pattern — developers proposing large facilities, communities balking, projects dying — convinced state legislators that a formal pause and study process was needed before the next wave of proposals arrived.
Data centers have become a target of growing community resistance across the United States, particularly in rural areas where the facilities' demands for water, power, and land often clash with local character and infrastructure capacity. Maine, with its relatively low-cost power, available land, and cool climate (which reduces cooling costs), has attracted developer interest despite having no existing large-scale facilities.
The Loring Case Study
The most concrete project affected by LD 307 is the Loring LiquidCool Data Center, planned for the site of the former Loring Air Force Base in Aroostook County. The facility, being developed by Minnesota-based LiquidCool Solutions, has a will-serve agreement with Versant Power for 24 megawatts — placing it above the moratorium threshold, according to the Bangor Daily News.
Herb Zien, vice chair of LiquidCool Solutions, told the Bangor Daily News that the company could live with capping at 20 megawatts for now, though the constraint complicates project financing. The facility is planned for a 115,000-square-foot warehouse at the former base and would use LiquidCool's immersion cooling technology, which the company says eliminates water usage — addressing one of the key concerns raised about data center development. Zien described the site as "almost move-in ready" when the project was announced in October 2025, and said it would be the first large-scale AI data center in Maine if completed.
Under the moratorium, the facility could not scale beyond 20 megawatts until the study council reports. Zien said in March that the company hoped to finalize financing within a month and become operational roughly six months after that, though he cautioned that nothing is guaranteed "until the money is in the bank."
The National Significance
If enacted, Maine's moratorium would be the first state-level restriction of its kind in the United States, setting a precedent other states could follow. The data center industry is in the midst of an unprecedented construction boom driven by artificial intelligence demand, with hyperscalers and cloud providers racing to add capacity. Industry analysts have projected that data centers will account for an increasing share of U.S. electricity consumption over the coming decade.
That growth has generated a backlash in communities from Virginia to Texas to Nevada, where residents have organized against proposed facilities over concerns about noise, power consumption, water use, and property impacts. Maine's legislation would be the first time a state government codified that community resistance into a statutory pause.
An opinion piece published by the Bangor Daily News on March 30 argued that the moratorium would "stop Jay mill redevelopment," referencing a proposed data center conversion at a former paper mill in Jay, Maine — illustrating the tension between economic development aspirations for struggling rural communities and the statewide regulatory push.
A Central Maine opinion piece published April 1, 2026 noted that "Maine currently has no large-scale data centers and none under construction, even as other states move ahead with dozens of sites. Yet we seem poised to become the first state to impose a blanket moratorium on an industry that hasn't even arrived yet." That framing captures the unusual nature of the legislation: a preemptive state-level pause on an industry that has barely taken root.
What Comes Next
The bill must still complete the legislative process and receive the signature of Governor Janet Mills before taking effect. As of early April 2026, the legislation had advanced through committee and the legislature but had not yet been reported as signed into law. Governor Mills has not made a public statement on the bill as of this writing.
The data center coordination council, once established, would be charged with studying the impacts of large data centers on Maine's power grid, water supply, tax base, land use, and communities, and recommending policies for the legislature. Its report would trigger the 90-day clock before the moratorium lifts.
For the broader data center industry, Maine's action is a warning sign: community and legislative resistance to unchecked expansion is no longer confined to local zoning fights. It is now reaching state legislatures in the form of statutory moratoriums — and if Maine succeeds, it will not be the last.
Maine may not have a single large data center yet. But it may be the place where the data center era's first regulatory reckoning takes hold.
