- Status
- Vetoed
- Applies to

- Enforced by
- N/A (vetoed)
Maine's legislature became the first in the nation to pass a statewide data center moratorium — a pause on data centers over 20 megawatts until November 2027 — but Gov. Janet Mills vetoed it on April 24, 2026. She said she supports a temporary moratorium but wanted an exemption for development already underway at the former Androscoggin Mill site in the town of Jay. So there is no statewide Maine data center moratorium; local moratoriums (e.g., Bangor) still apply.
Who is protected: (Would have protected) Maine ratepayers and communities near large data centers — not in effect
Legal detail
LD 307 (HP 207, 132nd Legislature), 'An Act to Establish the Maine Data Center Coordination Council and Place a Temporary Limitation on Certain Data Centers' (sponsor Rep. Gattine), would have created a 13-member council to study data center siting (report due Feb. 1, 2027) and placed a moratorium on municipal and state permitting of data centers with a load of 20 MW or more until Nov. 1, 2027. Vetoed by Gov. Mills April 24, 2026 (citing the lack of an exemption for the former Androscoggin Mill site in Jay); veto sustained April 29, 2026 — not law.
