State-level measures in Illinois
Every statewide moratorium, pause, siting restriction, or tax-incentive rollback in Illinois we can verify against a primary source. Strongest status first.
| Measure | Status | What it does | Source |
|---|---|---|---|
| Illinois (statewide)Illinois: Governor J.B. Pritzker announced a two-year suspension of state tax incentives for new data centers, effective July 1, 2026. | In force 2026-06 | Governor J.B. Pritzker announced a two-year suspension of state tax incentives for new data centers, effective July 1, 2026. The freeze applies to the state's data center tax exemption program. Still requires Illinois General Assembly approval to take effect. The announcement comes amid growing community opposition to data center developments across Illinois, including fights in Sangamon County, Mount Prospect, and DeKalb. On June 5, 2026, after the legislature failed to act on his February request, Gov. Pritzker directed the Dept. of Commerce & Economic Opportunity to pause processing new Data Center Investment Program tax-incentive agreements starting July 1, 2026 (existing agreements honored). He paired it with a consumer-protection framework: ban local-government NDAs, require energy/water reporting and public permit notices, and require community benefit agreements; he plans to press the issue in the November veto session. The DCEO's pause on new Data Center Investment Program tax-incentive agreements took effect 2026-07-01 (a 2-year suspension), after the POWER Act (data center cost-allocation, renewable-energy, and blackout-compliance reform) failed to pass before session end. Gov. Pritzker is pushing to revisit the issue in the November veto session. | |
| Executive directivePause on new data center tax incentives | Paused 2026-07 | Gov. Pritzker directed the Dept. of Commerce and Economic Opportunity to stop processing new data center tax-incentive deals from Jul 1 2026 after the legislature adjourned without reforms. | |
| SB 4016 / HB 5513Hyperscale self-generation and water transparency | Proposed 2026-02 | Would require hyperscale data centers of 50 MW or more to fund their own energy generation from renewables, mandate water usage transparency and efficiency standards, and require environmental impact assessments. Before the Senate Artificial Intelligence and Social Media Subcommittee. | |
| POWER ActProtecting Our Water, Energy, and Ratepayers Act | Proposed 2026-09 | Governor JB Pritzker urged Illinois lawmakers to pass the POWER Act in the next legislative session after the November 2026 election; the bill was worked on in the spring but not enacted, and Pritzker emphasized it would require data centers to bring their own power and water and adhere to environmental protections, without imposing a moratorium. | |
| SB 4004Illinois: In Illinois, SB 4004 would permanently ban data centers from using Mahomet Aquifer groundwater, The sole-source drinking water for ~1 million people | Failed / vetoed 2026-02 | In Illinois, SB 4004 would permanently ban data centers from using Mahomet Aquifer groundwater, The sole-source drinking water for ~1 million people across 14 counties. Also prohibits local governments from entering NDAs with data center companies and requires transparency in water usage. The outcome remains pending. The community's stated objective was to ban data center development NDAs in IL. SB 4004 (Mahomet Aquifer ban) was re-referred to Senate Assignments May 22, 2026 with no floor vote; dead for the session (ends May 31). |

What does bind large loads in Illinois
A moratorium is only one way a data center gets stopped. The grid operator decides whether it can connect at all, and on what terms. Illinois sits in 2 footprints.
PJMDominant
Large loads must bring new capacity or be curtailed first. Filed, pending at FERC.
MISO
Faster parallel studies and a co-located generation fast track, not a pause.
ComEd zone (northern IL/Chicago, ~70% of the state's population) is PJM; Ameren Illinois and MidAmerican downstate are MISO.
States next door
5 of the 5 states bordering Illinois have at least one data-center measure on record. Restrictions tend to travel between neighbors, so this is usually where the next one comes from.

How to read this page
In force = a moratorium, siting restriction, or tax-incentive rollback that is currently enacted, by statute or executive order. Paused = a temporary hold on new incentives or applications. Proposed = introduced and still pending. Failed / vetoed = died in committee, was voted down, or was vetoed.
This page is generated from the same primary-sourced dataset as the national U.S. Data Center Moratorium Tracker and is re-checked on the same weekly cycle, whether or not anything changed. Legislative status changes quickly; it is informational, not legal advice. Spot something out of date in Illinois? Tell us.

Why Illinois is pushing back
The objections repeat from state to state: strain on the electric grid, water drawn for cooling, and the sense that a facility takes local resources without giving much back. SAVRN builds AI factories designed around those three objections: on-site power that does not lean on the public grid, direct-to-chip cooling that does not consume municipal water, and a training institute that puts local people to work inside the building.
