Maine Governor Vetoes Data Center Moratorium

Governor Janet Mills vetoed LD 307 on April 24, 2026, blocking what would have been the first statewide pause on large-scale data centers in the United States.

The bill intended to halt approvals for facilities requiring over 20 megawatts of power until October 2027, allowing the state time to study their impact on the electrical grid and local water supplies.

The “Jay” Conflict

While Governor Mills expressed support for the concept of a temporary pause, she rejected the bill due to its lack of flexibility regarding a specific redevelopment in the Town of Jay.

Current Status and Outlook

The fate of the moratorium now rests with the Maine Legislature:

  1. Override Attempt: Lawmakers could attempt to override the veto, though this requires a two-thirds majority in both chambers.
  2. Revision: The legislature may draft a new version of the bill that includes a “carve-out” for the Jay project to satisfy the Governor’s requirements.

Why It Matters

Maine has recently seen a surge in “hyperscale” data center proposals. While these bring investment, they have also sparked significant community pushback regarding rising utility costs and the high water consumption required to cool massive server farms. This veto highlights the growing tension between state-level environmental goals and local economic recovery.
