On June 5, 2026, Governor Pritzker directed the Illinois Department of Commerce and Economic Opportunity to stop processing new agreements under the Data Centers Investment Program beginning July 1. Existing agreements — those entered into with DCEO before July 1, 2026 — are being honored.
The coverage generally described this as Illinois turning against data centers. That is not what happened, and the difference matters if you own ground under option, sit on a village board, or have a project part-way through.
What the program was
The Data Centers Investment Program, created in 2019, was one of the more generous state incentives on the books. A qualifying facility received exemptions from state and local sales and use taxes — running as long as twenty years through renewable certificates — on the equipment and materials that go into a data center.
The qualifying thresholds were real:
- $250 million in capital investment over a 60-month period;
- at least 20 full-time or full-time-equivalent jobs, paying at least 120 percent of the median wage for the county where the facility sits; and
- carbon neutrality or certification under an approved green building standard.
The state has approved the large majority of applications it received. The Department's own reporting has put the state and local tax revenue foregone in the neighborhood of $983 million across an initial five-year window — which is the number that drove the politics.
What the pause does, and what it does not do
Three distinctions are worth keeping straight.
It pauses the incentive, not the industry. Nothing about the Governor's directive prevents anyone from building a data center in Illinois. Whether a project gets built is decided by county or municipal zoning and by whether a utility can actually serve it. Neither is affected by whether the developer gets a sales tax exemption.
It is administrative, not statutory. The program was not repealed. DCEO was directed to stop processing new agreements. The Governor first signaled a two-year suspension in the February 2026 budget address and has called on the legislature to build a durable framework during veto session. What comes out of Springfield could look very different from a pause.
Grandfathering is where the lawyering is. “Agreements entered into before July 1, 2026” is a clean sentence covering a messy reality. An applicant with a fully executed memorandum of understanding is in a different position from one that filed an application and was still in review, which is different again from a project that was assembling land and had not applied. If you are anywhere in that middle band, the answer depends on your documents and your dates, not on the press release.
Why it happened
The pause followed a failed legislative session. The POWER Act — the Protecting Our Water, Energy, and Ratepayers Act, filed as HB 5513 and SB 4016 — would have imposed transparency requirements, water reporting, community impact assessments, and a requirement that data centers carry their own energy and infrastructure costs. It did not advance in the spring 2026 session. Two narrower bills aimed at local control also went nowhere: one that would have let municipalities set concentration and proximity standards and required public hearings, and another that would have put data center proposals to local referendum.
When the legislation stalled, the executive branch used the lever it had. Alongside the pause, the Governor laid out a framework he wants the General Assembly to enact, and it is worth reading as a preview of the next bill:
- Dedicated rate classes for data centers, so they bear the grid and water costs they cause;
- A pause on incentives while the state evaluates what they are actually buying;
- Curtailment obligations — data centers reducing consumption when the grid is strained;
- A requirement that facilities generate or fund their own clean power rather than drawing down existing supply;
- Comprehensive water permitting and statewide monitoring;
- Emissions standards for backup generation, with attention to environmental justice communities; and
- Mandatory public notice and reporting, community benefits agreements, and a ban on nondisclosure agreements between developers and local governments.
That last item deserves a moment. NDAs between developers and local officials have been standard practice in site selection. A statutory ban would change how these deals get negotiated in every county board in the state.
What is still moving while the incentives sit still
The regulatory side did not pause at all.
In March 2026, the Illinois Commerce Commission approved a revised ComEd tariff (Docket P2025-0677) increasing the security deposits large-load customers must post — starting at $1 million for projects requesting 50 to 200 megawatts and rising by $500,000 for each additional 100 megawatts. The purpose is to keep the cost of building out to serve a data center from landing on everybody else if the project shrinks, moves, or never materializes. In the same order the Commission directed its staff to open a broader investigation into protecting residential and small business customers from data center-driven distribution costs, to be completed within roughly eight months.
One caveat that matters here: that order is ComEd's, and ComEd does not serve this part of the state. McLean, DeWitt and Logan counties are Ameren Illinois territory. The Commission's reasoning will shape what happens downstate, but the specific tariff does not apply here — do not assume a central Illinois project is subject to it.
What it means depending on where you sit
If you own ground under option. The economics of the project on your land may have just changed, and your option agreement probably did not anticipate it. Look at whether the developer can extend on the same terms while it waits for Springfield, whether there is a termination right tied to incentives or approvals, and whether the option payments still make sense for a timeline that just got longer. If the developer wants an amendment, that is a negotiation, not a formality.
If you are a local government. The state subsidy is off the table for new entrants, which means the value proposition presented to your board is now more dependent on property tax and local agreements than it was six months ago. It also means the incentive question and the zoning question have separated cleanly — a developer that cannot get a state exemption can still ask you for a special use, and you should evaluate that request on its own terms. If a proposed community benefits agreement or an NDA comes with it, read both carefully.
If you are a business or a landlord near one of these sites. The rate question is the one to watch, not the incentive question. Whether large new loads end up paying their own way is being decided in Commission dockets, not in the incentive program, and it will show up on your bill either way.
The practical read
Illinois has not decided what it wants. It has bought itself time and moved the argument to veto session. For anyone with money or land committed to one of these projects, that means a stretch of genuine uncertainty — and the people who come through it well will be the ones whose agreements anticipated a delay rather than assumed a schedule.
If you have a project, an option, or a board decision caught in the middle of this, the documents and the dates decide it. Bring them in.
