Maine's Janet Mills Vetoes Data Center Moratorium, Shifts Power

Governor Mills blocks a pause on new data centers in Maine.

Janet Mills’ Veto Keeps Maine in the Data Center Race

Mills blocked a first-in-the-nation pause on new data centers, shifting leverage back to developers as states battle over AI-era power demand.

Gov. Janet Mills has killed the bill that would have made Maine the first state to impose a moratorium on new data centers, cutting off a legislative attempt to pause development while the state wrote new rules. The proposal was driven by concerns over electricity demand, water use, wastewater, noise, local tax deals and whether rural permitting systems are built for hyperscale projects.

Who gains from the veto

Mills now holds the leverage. By vetoing the moratorium, she kept Maine open to investment and denied lawmakers the one tool that would have forced developers to wait.

The winners are straightforward: data-center developers, utilities and municipalities that want projects moving before a tighter statewide framework arrives. The losers are the lawmakers and local officials who wanted time. The bill, backed by Rep. Melanie Sachs, would have paused new projects above 20 megawatts until Nov. 1, 2027, created a Data Centre Co-ordination Council, and required a report by February 2027 before large-scale buildouts resumed.

The bigger political point is that Mills has broken with a rising anti-data-center current. CNN reported earlier this month that Maine’s bill had bipartisan support and sat within a wider wave of proposed moratoriums and local restrictions in states including New York, South Carolina, Oklahoma and Vermont. Data centers are spreading around the country. Now, data-center bans are, too

Why Maine matters nationally

This is less a land-use dispute than a fight over who captures the upside of the AI build-out and who carries the infrastructure risk.

That risk is growing fast. The U.S. Department of Energy estimates data-center electricity use has tripled over the past decade and could double or triple again by 2028, reaching about 12% of U.S. electricity demand. Meta's nuclear deal signals AI's growing energy needs

That is why this Maine veto matters beyond Augusta. In the wider US Politics and United States debate, states face a hard trade-off: block projects and lose tax base and construction spending, or approve them quickly and risk locking ratepayers into grid upgrades before demand forecasts are proven. AP has reported that regulators and lawmakers are already questioning utility load forecasts tied to data centers because some projects remain speculative or may be double-counted across service territories. Scrutiny rises of utilities' power projections for data centers

What to watch next

The next decision point is whether Maine lawmakers try to override the veto or come back with a narrower bill aimed at siting, water use, transmission costs or ratepayer protections rather than a blanket pause. Just as important: whether developers move quickly to file projects while statewide rules remain unsettled.

Mills won the timing fight. The real test now is whether Maine can write a framework before project momentum outruns state control.
