- Ballot initiatives signal growing local and bipartisan resistance
The Shift Away from Incentives
The turn of the decade saw state and local governments offering robust incentives for data center development. The current landscape is markedly different. This new landscape was evident at the outset of the year, when Governors’ across the nation emphasized affordability, cost protection, and solving energy demand issues in their state of the states addresses.
Amid growing public concern about the cost of electricity, lawmakers across the country are re-evaluating how large-load facilities are integrated into local economies. These approaches range from agreements with hyperscalers to ensure equitable cost allocation, “bring your own power” models, and partnerships between developers and communities to provide community benefits.
However, some lawmakers are going further. Instead of refining tariff and agreement structures, they are proposing outright bans, pauses, or stringent siting requirements on new data center construction.
In 2026 alone, fourteen states have introduced legislation to establish a pause or moratorium. Maine’s first-in-the-nation moratorium passed the legislature on April 14 before being vetoed by Governor Janet Mills on April 24.
Temporary Moratoria: A “Pause to Study”
Most legislative efforts to date have focused on temporary pauses designed to allow for comprehensive impact assessments.
In Maine, LD 307 establishes a temporary pause until 2027 for facilities exceeding 20 MW while a council evaluates long-term impacts on grid reliability and ratepayers. Governor Mills vetoed the legislation, noting that while she broadly supported the intent, the bill did not include an exemption for a planned data center in Jay. That project, set to replace a mill that closed in 2023, is expected to provide a significant economic boost to the region. Despite the veto, the governor indicated she will move forward with establishing a similar council.
Several other states are pursuing comparable approaches:
- Oklahoma (SB 1488): Moratorium until 2029 to study impacts on water supply and property values
- New York (S9144): Temporary halt on permits for facilities over 20 MW pending environmental review
- Michigan (HB 5594): Prohibits approval and operation of data centers until April 2027
- Kansas (SB 531): Targets water-constrained counties rather than implementing a statewide pause
From Pauses to Permanent Restrictions
Some states are moving beyond temporary measures and proposing stricter, long-term land-use controls.
In Missouri, HB 3390 would prohibit hyperscale data centers in areas designated for agricultural, residential, or conservation use. The measure also mandates 500-foot setbacks and restricts construction within ten miles of certain recreational lands and five miles of state waters.
Virginia took a similarly aggressive approach. HB 1515 would have prohibited localities from approving rezoning or site plans for new data centers until 2028 or until existing interconnection requests were fulfilled.
Although efforts in Virginia, Georgia (HB 1059), South Dakota (SB 232), and Wisconsin (SB 1061) failed to advance, the volume and scope of these proposals underscore how quickly the policy landscape is evolving.
Ballot Initiatives Signal Broader Public Pushback
This shift is not limited to state legislatures. It is increasingly appearing at the ballot box.
Statewide moratorium initiatives have been proposed in California and Ohio, though the Ohio measure is unlikely to secure enough signatures to appear on the November ballot. California’s goes broader and covers “essential projects” that include local approval for broader energy, public health, and transportation projects. These efforts reflect growing public skepticism across regions and political alignments.
At the local level, ballot measures are even more varied, ranging from outright bans to increased voter control over development decisions:
- Monterey Park, CA (Measure NDC): Would amend land use rules to prohibit data centers
- Port Washington, WI: Voters approved a measure requiring approval for Tax Incremental Districts exceeding $10 million
- Janesville, WI: Will vote on requiring approval for developments exceeding $450 million
- Eldorado Valley, NV (Question 1): Would require voter approval for data center development in designated areas
Together, these measures signal a growing desire for direct community input in large-scale infrastructure decisions.
What This Means Going Forward
Legislative and municipal actions point to a clear transition toward a more rigorous regulatory environment for data center development.
The era of broadly incentivized expansion is giving way to one centered on long-term resource management, grid reliability, and community benefits. Whether through state-mandated moratoria, environmental review requirements, or direct voter participation, the future of large-scale data infrastructure is increasingly shaped at the local level.
