GOVERNOR MILLS SHUTS DOWN LEGISLATIVE ATTEMPT AT MORATORIUM
Maine Governor Janet Mills on April 23, 2026, vetoed legislation that would have imposed the nation's first statewide moratorium on new large-scale data centers. The bill, which had cleared both houses of the state legislature, aimed to pause construction of facilities consuming 20 megawatts or more of power.
The veto arrived shortly after lawmakers rejected an amendment seeking an exemption for a proposed data center project in Jay, Maine. Mills, according to statements, signaled a preference for a measured approach over an outright ban, indicating she would instead pursue an 'executive order to create a council to examine the impact of data centers'.
LEGISLATIVE DEBATE AND EXECUTIVE ACTION
The proposed moratorium emerged as a response to escalating community concerns over the rapid proliferation of data centers, driven by the current fervor surrounding artificial intelligence development. While at least a dozen states have seen similar legislative proposals, Maine's bill had advanced further than others.

Mills stated, "Given the serious conversations about data centers here and around the country, I believe this work should commence without delay.”
The governor’s office framed the veto as a move to allow for a more thorough assessment of data center impacts, including their benefits and risks to the state. This council, as envisioned by Mills, would provide "strategic input, facilitate coordinated state planning considerations and evaluate policy tools."
Concurrently, Mills signed another bill, LD 713, which bars data centers from benefiting from Maine’s business development tax incentive programs. This action suggests a bifurcated approach, curbing financial incentives while rejecting a complete construction freeze.
OPPOSITION AND CRITICISM
The governor's decision has drawn criticism from various quarters, including environmental groups and some lawmakers who had supported the moratorium. Opponents argue that the veto undermines efforts to proactively manage the growth of the data center industry and its potential strain on local resources, particularly energy consumption and infrastructure.

Data center developers, chambers of commerce, technology firms, and electric utilities have historically voiced opposition to such moratoriums, often advocating for less restrictive regulatory frameworks.
NATIONAL CONTEXT
Maine's legislative push and subsequent veto occur against a backdrop of widespread debate across the United States regarding data center expansion. The swift rise of artificial intelligence has intensified the demand for these facilities, prompting a wave of proposals for bans or temporary halts in numerous states. None of these proposals, apart from Maine's, had previously advanced beyond a legislative chamber.
