Maine Governor Vetoes Statewide Data Center Moratorium

Apr 26, 2026

Maine Governor Janet Mills, a Democrat running for U.S. Senate, vetoed L.D. 307, which would have created the nation's first statewide data center moratorium lasting until November 1, 2027. The bill, sponsored by Democratic state representative Melanie Sachs, would have halted permits for new data centers and established a 13-person council to study their impacts. Mills stated she would have signed the legislation if it exempted a data center project in the Town of Jay that enjoys strong local support. Sachs warned the veto poses significant consequences for ratepayers, the electric grid, and Maine's energy future, while Mills acknowledged that pausing data centers would be appropriate given their environmental and electricity rate impacts in other states.
