The moratorium can extend to March 2027 if city officials determine that additional time is needed
Decision Focus
Troy, Illinois voted to cap data center electrical demand at 30 MW and ban hyperscale facilities outright — a direct response to a rejected 500 MW proposal. Illinois Senate Bill 2181, which would have preempted local ordinances for non-home rule municipalities, failed to pass. Governor Pritzker then issued an executive order rolling back all data center tax incentives in the state. For Global Heads of Data Center Energy, the operational signal is clear: municipal-level resistance is no longer a permitting friction — it is becoming a structural site-selection variable in Illinois, and peer municipalities are watching the same playbook.
90-Second Brief
In recent days, troy’s planning commission, meeting June 11, confirmed that the city’s moratorium, active since mid-March 2026 and expiring mid-September, has produced binding changes: a 30 MW facility cap, 1,000-foot setbacks from schools and residences, mandatory renewable energy sourcing, closed-loop cooling requirements, and a decommissioning bond set at 150% of original construction cost. The moratorium can extend to March 2027 if city officials determine that additional time is needed. At the state level, SB 2181’s failure removes any near-term prospect of preempting these local restrictions for non-home rule cities, while Pritzker’s executive order eliminates the financial incentive layer that once made Illinois a competitive data center destination.
What Is Really Happening?
Troy’s moratorium and its resulting ordinance framework did not emerge from bureaucratic inertia. They followed direct citizen pressure against a proposed 500 MW hyperscale campus — a project that would have drawn power equivalent to a mid-sized city substation onto a community of roughly 11,700 residents. The 30 MW cap is not an engineering standard; it is a political boundary drawn in response to scale anxiety.
What amplifies this beyond a single small-city story is the failed state preemption attempt. SB 2181 was specifically designed to create the Illinois Data Center Energy and Water Reporting Act and override local control for non-home rule municipalities — precisely the category Troy falls into. Its failure means there is no state-level safety valve for developers who assumed Springfield would eventually clear the path. Troy’s framework can now stand, and similar municipalities are watching. City officials confirmed they are already referencing Aurora, St. Louis, and Lake and LaPorte counties in Indiana as models, suggesting an active ordinance-sharing network among smaller Illinois jurisdictions.
Governor Pritzker’s executive order withdrawing data center tax incentives adds a third compounding factor. Illinois had used those incentives as a draw for large-scale investment. Their removal changes the cost calculus for any project underwriting its pro forma on incentive capture — particularly for facilities in the sub-100 MW range that cannot spread fixed Illinois development costs across a hyperscale asset base.
Why It Matters for Global Heads of Data Center Energy
The 30 MW cap is operationally disqualifying for any hyperscale or AI-compute campus. No colocation operator building for GPU-dense workloads, and no hyperscaler with multi-hundred-megawatt campus requirements, can work within that constraint. Troy is off the site map entirely for large-scale builds.
The broader consequence is more complex. Troy’s ordinance package — setbacks, renewable sourcing mandates, decommissioning bonding, noise limits, and closed-loop water systems — represents a template that other non-home rule Illinois municipalities can adopt. The three-step approval process Troy is drafting, which includes mandatory 14-to-30-day review intervals between city council hearings and an option to return projects to the planning commission for re-examination, structurally extends development timelines. For energy teams modeling interconnection and permitting sequences, that additional variability compounds the existing 3-to-7-year grid interconnection cycle.
Decommissioning bonds set at 150% of original construction value introduce a material capital structure consideration. On a large facility, that bond amount affects project financing and balance sheet planning, and the liability persists throughout the facility’s life.
The renewable energy requirement, added as a percentage mandate without a specified threshold in current draft form, creates procurement uncertainty. Until the percentage is codified, any site underwriting in Troy — or in peer municipalities watching this framework — cannot lock a clean energy procurement structure with confidence.
Forward View
Three fronts deserve monitoring. First, the Illinois fall veto session runs October 14 to October 30. Troy officials explicitly stated they will watch whether a revised data center ordinance resurfaces. If it passes in a form that restores state preemption, the local restriction landscape resets. If it does not, Troy’s model — and the models of the municipalities it is referencing — becomes more entrenched and more likely to spread.
Second, the moratorium itself expires mid-September. If Troy’s commission determines the ordinance framework is not complete, a six-month extension to March 2027 is available. A second moratorium would signal that the approval architecture is not converging quickly, lengthening the planning horizon further for any developer watching this market.
Third, watch whether Illinois’s withdrawn tax incentives prompt competing states to move aggressively on their own incentive packages. If neighboring Midwest states accelerate programs in response, site selection pressure in the region may shift quickly — requiring energy infrastructure teams to re-score interconnection readiness and utility relationship depth in those alternative markets.
What Is Still Uncertain
The renewable energy percentage requirement is unconfirmed. The ordinance remains in draft form and the specific mandate has not been set. Until it is, the procurement and PPA implications cannot be sized.
Whether the state legislature reconvenes on data center policy in the fall veto session is explicitly unknown — Troy officials acknowledged they have no visibility into that outcome. A preemption bill passing in October would materially change this analysis, restoring developer optionality in non-home rule jurisdictions.
It is also unclear how Troy’s framework will interact with utility interconnection timelines in that part of Illinois. The source does not address grid capacity, substation availability, or Ameren service territory dynamics. A 30 MW cap is theoretically more achievable from a grid standpoint than a 500 MW campus, but the utility impact requirements in Troy’s emerging ordinance remain unspecified.
One Question for Your Team
If a peer municipality adjacent to one of your active or planned Illinois sites adopts Troy’s ordinance template — including the 30 MW cap, decommissioning bond, and renewable mandate — does your current site underwriting model have a trigger point for flagging that risk before interconnection commitments are signed?
