Maine Governor Janet Mills vetoed L.D. 307 on Tuesday, killing what would have been the first statewide moratorium on new data center construction in the United States. The bill would have frozen all new data center permits until November 1, 2027, a nearly three-year halt targeting the industry's rapid expansion across the state.
The veto matters beyond Maine's borders. Other states are watching. Data center moratorium legislation is appearing in statehouses nationwide, driven by concerns over power grid strain, water consumption, and local zoning displacement. Maine's bill was the test case. It failed at the executive level, not the legislative one, which tells you where the pressure points are.
The full article is worth reading for the legislative record: how far L.D. 307 got, which constituencies pushed it, and what Mills cited in her veto reasoning. The policy fight is not over. It just lost its first clean shot at becoming law.
