Maine is poised to become the first state in the U.S. To implement a statewide ban on large data centers. On Tuesday, April 14, 2026, lawmakers in both chambers of the Maine legislature passed a bill that establishes an 18-month moratorium on the development of new, high-power data facilities passed by the Maine legislature.
The legislation specifically targets “power-hungry” facilities that harness more than 20 megawatts of power—an amount of electricity sufficient to power more than 16,000 homes. The primary goal of the moratorium is to provide a designated task force with the necessary time to study the risks and benefits of these facilities, particularly regarding their impact on the state’s electrical grid Maine Lawmakers Pass the First Statewide Ban on Large Data Centers.
The bill now moves to Governor Janet Mills for her signature or veto. However, the governor has expressed significant reservations about the legislation in its current form, insisting on a specific “carveout” for the town of Jay. Mills has argued that the local community needs the jobs associated with a proposed data center project to recover from the economic blow of the Pixelle paper mill closure Mills pushes for Jay exemption in data center bill.
The Drive Toward a Data Center Moratorium
The push for this legislation is led by state Representative Melanie Sachs (D-Freeport), who sponsored the bill. Sachs has described the measure as a “thoughtful, proactive step” to ensure that Maine has a proper regulatory framework in place before allowing the proliferation of massive computing hubs. According to Sachs, several other states that previously incentivized data center development are now rethinking their strategies as the full scale of the grid and environmental impacts becomes clearer Mills pushes for Jay exemption in data center bill.
The rise of artificial intelligence (AI) software has driven an unprecedented demand for computing power, leading to a surge in data center construction across the United States. These facilities—essentially massive buildings housing thousands of computer systems—require immense amounts of electricity and water for cooling. This has sparked a growing backlash from local communities concerned about rising electricity prices and the overall environmental footprint of the industry Maine Legislature passes first in the nation ban on data centers.
The scale of the challenge is highlighted by data from the Lawrence Berkeley National Laboratory, which found that data centers accounted for approximately 4.4% of total U.S. Electricity consumption in 2023. The report suggests this figure could double or even triple by 2028, placing significant strain on energy infrastructure nationwide Mills pushes for Jay exemption in data center bill.
The Conflict Over the Jay Exemption
Although the legislature has passed the bill, a political standoff remains between the lawmakers and Governor Janet Mills. The governor is championing a proposed $550 million project located at the former Androscoggin paper mill in the town of Jay Maine Legislature passes first in the nation ban on data centers.
Governor Mills has stated that the people of Jay need the jobs this project would bring, provided You’ll see “appropriate guardrails” to protect water resources, electricity resources, and local generation. On March 23, the Jay Board of Selectpersons contacted the governor, urging her to veto the bill unless an exemption for their town was included, citing the “profound and lasting negative impact” caused by the closure of the Pixelle paper mill Mills pushes for Jay exemption in data center bill.
Despite the governor’s public appeals and the requests from Jay town officials, the Maine legislature ultimately rejected amendments that would have created exceptions for projects like the one in Jay Maine Lawmakers Pass the First Statewide Ban on Large Data Centers. This puts the governor in a position where she must decide whether to sign a bill that blocks a project she believes is vital for a local economy or veto the first-in-the-nation ban on large-scale data centers.
What Happens During the 18-Month Window?
If the bill is signed into law, the 18-month moratorium will serve as a cooling-off period. During this time, a coordinating council consisting of government officials, industry experts, and other stakeholders will be tasked with studying the risks and benefits of these facilities Maine Legislature passes first in the nation ban on data centers.
The council’s primary objectives will be to:
- Analyze the impact of high-power data centers on the state’s electrical grid.
- Evaluate the water consumption requirements and environmental consequences of these facilities.
- Develop policy recommendations and guidelines to limit negative impacts on future developments.
- Establish a regulatory framework that balances economic growth with resource conservation.
This approach reflects a growing trend of “regulatory caution” as states grapple with the rapid expansion of AI infrastructure. By pausing new developments over 20 megawatts, Maine aims to avoid the pitfalls experienced by other states that offered aggressive incentives without first understanding the long-term utility and environmental costs Mills pushes for Jay exemption in data center bill.
Key Takeaways: Maine’s Data Center Ban
- Scope: 18-month moratorium on new data centers using more than 20 megawatts of power.
- Purpose: To allow a task force to study electrical grid risks and environmental impacts.
- Current Status: Passed by both legislative chambers. awaiting Governor Janet Mills’ signature or veto.
- Primary Conflict: Governor Mills seeks an exemption for a $550 million project in Jay to provide local jobs.
- National Context: First statewide ban of its kind in the U.S., driven by the energy demands of AI.
The next critical checkpoint is the decision by Governor Janet Mills. The governor’s office has not yet officially confirmed whether she will sign the bill or exercise her veto power in response to the legislature’s refusal to include the Jay carveout Maine Legislature passes first in the nation ban on data centers.
