Key takeaway

Twelve Indiana county freezes share no kill-switch, putting the pause beyond the reach of a single veto or lawsuit.

Boone County's commissioners voted unanimously on 15 June for a one-year pause on new data centres in unincorporated areas, running through 15 June 2027 while the county writes zoning rules ¹. It is the 12th Indiana county to enact such a moratorium. No bill went through the statehouse and no governor signed anything, yet Indiana now carries functionally statewide coverage assembled one county at a time.

Maine tried the single statewide route, and Governor Janet Mills vetoed LD 307 before it took effect, with the House sustaining the veto 72 to 65 . A veto kills one bill. Twelve county ordinances are twelve separate instruments, each defensible on local zoning-authority grounds, with no common target for a single lawsuit or executive strike. The cost to an operator is no longer lobbying one capitol but contesting a dozen county boards, which is the legal asymmetry that has made the freeze hard to undo. The wider US moratorium wave gave Indiana the template, with twelve states filing bills in April and five cities voting within a single week in May .

There is a carve-out, and operators have found it. Meta's existing campus sits in Lebanon's LEAP (Limitless Exploration Advanced Pace) innovation district, inside city limits by annexation, which exempts it from the county pause entirely. The breadth of the freeze and the narrowness of its exits now point developers toward the few annexed municipal districts where building can still proceed, concentrating build-out rather than stopping it.

Deep Analysis

In plain English

A county in Indiana called Boone County voted to pause all new data-centre building on 15 June 2026. It is the 12th county in Indiana to do this. The pauses last for one year while each county writes new planning rules for data centres. What makes this unusual is that nobody passed a law telling all Indiana counties to do this at the same time. Each county voted on its own. But because so many counties have done it independently, the effect is similar to a statewide ban, without anyone being able to overrule it from the top. Meta, the company that owns Facebook and Instagram, has a big data-centre campus nearby in a place called Lebanon. That campus sits inside a special economic zone that the city of Lebanon controls, not the county. So Meta's campus is not affected by the moratorium. In other US states, like Maine, a single law was passed and then vetoed by the governor, killing the whole effort at once. Indiana's approach of doing it county by county avoids that single point of failure.

Deep Analysis

Root Causes

Indiana's planning law assigns zoning authority to county commissioners for unincorporated areas, with no state-level override mechanism for single-use industrial categories. Data centres arrived in Indiana's agricultural counties faster than planning codes could be written to accommodate or restrict them, leaving commissioners with only two instruments: approve under existing agricultural-industrial zoning, or pause and write new rules.

The municipal-annexation carve-out for Meta's Lebanon LEAP campus reflects a second structural condition: Indiana's economic-development legislation was written to attract exactly the campuses that agricultural counties are now rejecting, creating a two-speed system where municipalities with annexation authority can pull sites inside their boundaries while counties in the same economic corridor vote to exclude new entrants.

The absence of a state moratorium bill means Indiana has no single-bill vulnerability of the kind that killed Maine's LD 307, but it also means there is no state mechanism to coordinate a coherent data-centre policy across the 12 counties, leaving each moratorium subject to its own legal challenge without a shared defence fund.

What could happen next?

Precedent
Indiana's county-by-county accumulation model is now the most legally durable US moratorium pattern, because it has no single veto point. Other states where statewide bills have failed may replicate the Indiana approach.
Risk
A Fifth Amendment taking suit against the weakest Indiana county, one with the thinnest legal resources and most explicit property-rights nexus, could collapse multiple county moratoriums simultaneously if courts apply the Hill County rescission precedent.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Indiana's county-by-county moratorium pattern mirrors the tobacco-ordinance diffusion of the 1990s, when individual Indiana counties adopted smoke-free workplace rules without any state enabling act from 1995 onward. By 2003, enough counties had adopted local ordinances that the state legislature passed a preemption law setting a uniform minimum standard.

The structural parallel is exact: an absence of state-level action creates space for county-level accumulation until the aggregate coverage either prompts state legislation or triggers a preemption fight. The data-centre question in Indiana is at the same inflection point the tobacco ordinances reached around 2001.

Counter-parallel: Arizona's attempt to use county-by-county zoning restrictions to control solar farm siting in the early 2020s collapsed when Maricopa County's ordinance was struck under Arizona's Right to Farm preemption statute, which courts read broadly to cover large-scale energy infrastructure on agricultural land.

Indiana has no direct equivalent of Arizona's preemption statute for data centres, but its LEAP district legislation, which gave Lebanon municipal annexation authority specifically to attract data-centre investment, was designed by the legislature to encourage the campuses that counties are now voting to exclude, creating a structural legislative contradiction the moratorium wave has made visible.

Consensus view: The Piedmont Environmental Council's local-government tracking and Data Center Watch's project-block database both identify county-level moratoriums as the fastest-diffusing instrument in US data-centre governance, because they require only a majority commissioner vote with no state legislative process, no gubernatorial signature, and no FERC jurisdictional exposure.

A county moratorium is procedurally equivalent to a zoning change, which courts have consistently treated as a valid exercise of police power.

Counter-view: The RCM Hill v. Hill County litigation established a Fifth Amendment regulatory-taking threat: when RCM Hill sued for $100 million on 28 May 2026, Hill County rescinded its moratorium within seven days rather than defend it in court.

Indiana counties face the same exposure. A developer with a contracted site can argue taking from the moment a moratorium blocks construction, and 12 separate counties cannot coordinate a joint legal defence without state-level assistance Indiana's legislature has not offered.

Key tension: Whether the county-by-county diffusion pattern is structurally durable against Fifth Amendment litigation or whether a single successful taking suit, targeting the weakest county in the set, collapses the Indiana model as quickly as it assembled.

Different Perspectives

NVIDIA

NVIDIA told the Securities and Exchange Commission on 26 August it had signed memorandums aiming to mobilise over $500bn for buyers' equipment purchases, then said in the same filing the arrangements may not become definitive. It may also carry limited residual-value risk on the equipment itself.

IREN Limited

IREN signed $2.4bn of financing on 25 August that only releases cash once its Mackenzie GPU servers are accepted, and only through 31 December 2026. A shipping delay from here now creates a funding problem as well as a revenue one.

Energy Commission (Malaysia)

Malaysia's Energy Commission recorded data centres at 9.3% of national power in one hot week in August, against a 7% year-to-date average, and is projecting 31% of peninsular demand by 2035. It wants roughly 9 GW of new gas-fired capacity by 2032 to cover the gap.

Economic Development Board and Infocomm Media Development Authority

Singapore's EDB and IMDA rationed 200 MW across four operators on 21 August and followed with a tropical liquid-cooling standard six days later, fixing the terms before construction starts. The agencies will decide within 18 to 24 months whether to run a third call.

Legal Resources Centre

The Legal Resources Centre put the water and power draw of two approved Cape Town Equinix sites in public, at roughly 4.4 billion litres and 1.4 to 1.5 billion kWh a year, because the city and the operator would not. It wants a cumulative assessment before any more of the five approvals proceed.

Ministerio de Minas e Energia

Brazil's energy ministry published Redata's five conditions after the Senate passed PL 278/2026 on 1 September, betting a repeatable annual water test enforces cooling design better than a one-off approval. Redata now needs President Lula's signature before any of it takes effect.
