Maine data – Maine Governor Janet Mills vetoed a bill that would have paused large data centers through fall 2027, while hinting at a revised approach via an executive order and tighter tax incentive rules.
Maine’s push to slow down large data center growth just hit a major roadblock. Governor Janet Mills vetoed a bill that would have halted new construction for roughly three years.
The measure had cleared both chambers of the Maine Legislature on April 14, but Mills rejected the approach as written.. Her stated direction was clear: she’s open to a temporary moratorium. yet she wanted an exemption for a specific project already in progress in Jay. Maine—an effort to avoid disrupting work that had moved beyond the early planning stage.
At the center of the bill was energy use.. It targeted proposals that consume 20 megawatts of power or more. instructing state agencies and other entities not to issue permits unless the proposal stays below that threshold.. That design reflects a growing reality for states: data centers don’t just require land and permits. they require reliable electricity—often at a scale that can strain existing planning timelines for grid upgrades and transmission.
The veto also left the fate of a proposed governance structure in limbo.. The bill would have required the creation of a “Maine Data Center Coordination Council. ” tasked with providing strategic input. coordinating state planning considerations. and evaluating policy tools related to data center opportunities and potential benefits and risks.
Rather than abandon the idea entirely, Mills signaled a path forward through executive action.. She said she would support an executive order that creates a council similar to the one proposed in the vetoed legislation.. That matters because coordination is often where policy either becomes practical—or stays theoretical.. Without a dedicated body, decisions about permitting, energy planning, and community impact can end up scattered across agencies.
Mills also took an additional step that goes beyond permitting.. She signed LD 713, which prohibits data centers from participating in Maine’s business development tax incentive programs.. For operators. incentives can function like a lever that makes investment timelines easier to justify; for state budgeting and competition concerns. removing that lever is a form of control even when construction proceeds.
This veto lands in a larger wave of political pressure across the country.. At least 12 other states have explored comparable restrictions or moratoriums. including New York. where lawmakers have introduced a bill seeking to block new data center construction for at least three years.. The federal landscape adds another layer: a bill backed by Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez would aim for a broader pause. covering not only new facilities but also upgrades to existing ones.
The broader tension is difficult to reconcile: slowing the buildout of data center capacity can ease pressure on power infrastructure. but it can also slow the AI and cloud services that rely on that capacity.. Maine’s debate mirrors a national question about sequencing—whether states should demand grid-ready certainty before large-scale compute expansion accelerates.
Misryoum sees the economic and community stakes in the operational details.. Large facilities can bring jobs and investment. but they also raise concerns about long-term power demand. land use. and the speed at which local systems can adapt.. When permitting rules are tightened. developers may shift investment elsewhere; when incentives are removed. states may reduce competition for scarce public benefits.. In both cases, the outcome shapes who bears the cost of transition and who captures the rewards.
Mills’ decision to veto the bill as written. while still moving toward coordination and restricting tax incentives. suggests a strategy of “manage the pace” rather than “freeze the market.” If the executive order achieves the council’s intended role—especially around energy forecasting and permitting coordination—Maine may end up with clearer rules that are easier to follow than a strict megawatt cutoff alone.
At the same time, the political context remains fast-moving.. A desire to limit data center expansion can clash with national momentum for quicker AI development and the infrastructure that powers it.. Misryoum is tracking how quickly the balance could shift: if federal AI policy continues pushing for faster buildout. states advocating pauses may need to justify them in terms that connect directly to grid reliability. permitting clarity. and measurable risk reduction—rather than simply slowing progress.
