Maine Data Center Moratorium 2026: The First State to Say No to the AI Boom — What It Means for Your Energy Bill

# Maine Data Center Moratorium 2026: The First State to Say No to the AI Boom — What It Means for Your Energy Bill

> **Quick answer:** Maine's legislature passed LD 307 on April 14, 2026 — an 18-month ban on new data centers consuming 20+ megawatts of power. It is the first statewide moratorium of its kind in the U.S., driven by electricity cost spikes and fears that AI's physical infrastructure is overloading New England's 30-gigawatt regional grid. Governor Janet Mills has 10 days to sign or veto. At least 10 other states are watching.

The Maine data center moratorium 2026 is the clearest sign yet that the AI boom has a physical ceiling. After years of tech giants racing to build AI infrastructure anywhere they could get permits and power, one state finally said: not here, not yet. And the reason is a bill you may be paying right now.

## What LD 307 Actually Does — The First State Ban on Data Centers

Maine's legislature made history in two stages. The House passed LD 307 on April 8, 2026, and the Senate followed on April 14. The bill does four concrete things:

**It halts large data centers through November 2027.** Any facility requiring more than 20 megawatts of power — roughly equivalent to the electricity needs of 16,000 average American homes — cannot break ground while the moratorium is active.
