Illinois at a glance
The largest footprint in Illinois belongs to Digital Realty Trust, Inc., behind 6 tracked facilities. NTT Global Data Centers, Equinix, Inc., and Meta Platforms, Inc. round out the most active operators in the state. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.
Geographically, the buildout clusters: Cook County leads Illinois with 32 facilities and a composite risk score of 21/100. DuPage County and DeKalb County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.
Illinois is not done growing. 15 facilities are in the pipeline — proposed, permitted, or under construction — which is where residents still have a say at zoning hearings and in rate cases. Each pending project is a decision about land, water, electricity prices, and tax revenue that hasn't been finalized.
We also surface the accountability trail: 8 state bills mentioning data centers and 6 recent news items are tracked for Illinois below, pulled from LegiScan and GDELT and refreshed automatically. Legislation is linked to the counties and operators it names; news is classified by community sentiment.
2035 Buildout Outlook
Under the model's moderate-growth scenario (5%/yr annual load growth), PNNL's IM3 model sites about 16 standardized 36 MW campuses in Illinois by 2035 — roughly 576 MW of new electricity demand and ~557 M gal/yr of cooling water. Under the higher-growth scenario (15%/yr) that climbs to 92 campuses (3.3 GW). For scale, we currently track 82 real data centers in Illinois (8.4 GW of reported power).
- Low growth11396 MW · ~383 M gal/yr cooling water
- Moderate growth16576 MW · ~557 M gal/yr cooling water
- High growth451.6 GW · ~1.6 billion gal/yr cooling water
- Higher growth923.3 GW · ~3.2 billion gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Illinois (the rest to mechanical/air cooling), a split it derives from local water stress and wet-bulb temperature.
These are modeled candidate sites, not announced or permitted facilities. PNNL's IM3 model places identical 36 MW unit-campuses at feasible locations under each scenario — it shows where demand could concentrate, never a specific parcel. Figures use a market-gravity weight of 50. How the model works.
