Maine Becomes First U.S. State to Ban Data Centers: Sanders and AOC Push for Federal Replication
Maine is about to become the first American state to ban the construction of new large-scale data centers. The Maine House of Representatives has approved the bill LD 307, which imposes a moratorium on the construction, permits, and operation of any data center with an electric load equal to or exceeding 20 megawatts, a threshold corresponding to the energy needs of about 15,000 homes. The measure is now expected to pass in the Senate, where its approval is anticipated, before being signed by Democratic Governor Janet Mills. Once the process is complete, the moratorium will remain in effect until November 2027.
The Genesis of the Bill
The bill was introduced in January 2025 by state representative Melanie Sachs (D-Freeport), chair of the Energy, Utilities and Technology committee, but it had been left pending at the end of the previous legislative session. In February 2026, Sachs added the moratorium clause to the original text, which initially only proposed the creation of a state advisory body. During a hearing, the representative explained that the effects of data centers on the power grid and the environment prompted legislators to "adopt a proactive approach, different from any other state so far."
The law also establishes the Maine Data Center Coordination Council, an agency mandated to protect consumers from tariff fluctuations, ensure grid stability, reduce environmental impact, and promote responsible economic development. It is the operational arm through which the state intends to assess the risks and benefits of the sector during the pause period.
Maine's Energy Context
Electricity prices in the state have increased by nearly 60% between 2021 and 2026, a significant rise for households and businesses even before large energy-intensive facilities come into play. The main concern is that data centers ranging from tens to hundreds of megawatts will further worsen this pressure on the grid, a system already strained particularly during winter months.
The most explicit opposition within the state parliament comes from Republican Senator Matt Harrington (R-Sanford), who has pointed out that the moratorium would jeopardize about 100 long-term jobs in his district, where a company had already purchased land and started the permitting process for a facility of 100-300 MW. The committee vote occurred along party lines, with Democrats in favor and Republicans against.
A Signal for the Rest of the Country
"I believe that Maine is the canary in the coal mine," said Anirban Basu, chief economist of the Associated Builders and Contractors, as quoted by the Wall Street Journal. "Maine will be the first of many states to adopt similar moratoriums." This prediction is far from baseless: according to the WSJ, at least ten other states are considering similar measures, and New York, South Carolina, and Oklahoma have already introduced similar bills. In an earlier stage of 2026, six states were already identified as potentially leaning toward a ban.
On the federal level, Senator Bernie Sanders (I-VT) and Representative Alexandria Ocasio-Cortez (D-NY) introduced the AI Data Center Moratorium Act on March 25, which would impose an indefinite nationwide halt on new construction until federal regulation on artificial intelligence is approved. The measure is unlikely to pass in the Republican-majority Congress, but it signals how central the issue is becoming politically. More than 200 environmental groups have reached out to Congress asking for similar measures.
Midterm 2026 and Tech Lobbying
The data center and AI issue is shaping up to be one of the central points of contention in the 2026 midterm elections. "There is a very strong fear among voters regarding data centers and AI," said attorney Tony Buxton of the Preti Flaherty firm to the WSJ. On the other side, major tech companies are fueling lobbying groups with hundreds of millions of dollars to sway public opinion before the vote, as reported by the Financial Times. The battle is therefore being fought on two simultaneous fronts: the legislative state level, where Maine Democrats have already made the first move, and the communication front, where AI giants have vastly superior resources.
In the meantime, the mere prospect of restrictive regulations is already producing tangible effects on the industry. In the second half of 2025, several data center projects were canceled even before reaching an advanced permitting stage. Tracey Hyatt Bosman, a consultant specializing in site selection for digital infrastructure, noted that proposed local regulations are already serving as a deterrent for developers.
