Maine Passes First Moratorium on Large Data Centers
Maine lawmakers passed a bill halting new large data centers until November 2027 amid power grid concerns.
Why it matters: Legal and compliance teams in energy, real estate, and environmental sectors must track Maine's precedent-setting pause, which could signal similar actions elsewhere. The law directly affects regulatory timelines and project planning for major data center investments.
- Moratorium halts approvals for data centers consuming over 20 MW until November 1, 2027.
- Maine Data Center Coordination Council will study impacts and issue a final report by February 2027.
- Recent proposals target Sanford and Jay for possible large data center projects, though none exist yet.
- Governor Janet Mills has not stated if she will sign the bill.
Maine lawmakers voted on April 14, 2026, to impose a statewide moratorium on construction of new data centers consuming more than 20 megawatts, making it the first U.S. state to take such action. The pause is set to last until November 1, 2027, pending the outcome of a comprehensive state study. (Washington Post)
- The law mandates that the Department of Energy Resources convene the Maine Data Center Coordination Council to examine the effect of data centers on the state's power grid, environment, and economy. A final report is due by February 1, 2027. (Maine House Democrats)
- No large-scale data centers currently operate in the state, but recent proposals target towns like Sanford and Jay for development. (Maine House Democrats)
- The bill passed the Maine House by 79-62 and the Senate by 21-13, reflecting significant debate. (Washington Post)
Rep. Melanie Sachs (D-Freeport), a key proponent, argued, "This bill positions Maine to respond deliberately and responsibly to a rapidly evolving industry." She cautioned, "Even two or three data centers can really impact the state as a whole." However, concerns about missed economic opportunities have been raised by business advocates and industry groups.
Governor Janet Mills has not yet indicated whether she will sign the bill into law, leaving the final step pending. (Washington Post)
By the numbers:
- 20 megawatts — Minimum power consumption for facilities affected by the moratorium
- April 14, 2026–November 1, 2027 — Moratorium period
- 79-62 — House vote margin approving the bill
Yes, but: Governor Janet Mills' decision is pending, leaving the law's fate uncertain.
What's next: If signed, the state council must deliver its data center impact report by February 1, 2027.
