Your action kit
Sourced arguments and ready-to-send letters — every figure links to a primary record. Edit to add your own story.
20 MW of new demand — roughly a city of 16,000 homes.
Large new loads can raise transmission and capacity costs that land on every ratepayer. Residential power in IL is 23.9¢/kWh, up 28.4% year-over-year. (MW→homes is a rough ~800/MW planning figure.)
SourceDemand a full, public review — not a rubber stamp.
Ask for an independent noise study, a water-and-power impact assessment, enforceable conditions (setbacks, hours, cooling type), and that the record stays open for written comment. Procedural shortcuts have voided approvals elsewhere.

Grid & water — why here
source: HIFLD · EPAThe closest existing grid infrastructure and the municipal water system this location sits in — the same constraints the buildout model screens on (it won't site a campus more than ~2 km from a substation or ~5 km from municipal water). Distances are straight-line to public HIFLD/EPA features, not a metered connection.

Tax breaks & subsidies
source: Good Jobs First / GASB 77No per-deal tax break is linked to this site yet. No state discloses the recipient of a data-center abatement at the facility level, so per-site deals are rare in the public record. If you have a development agreement or board resolution for this site, send it to us.
Illinois reported $983.2M in Data Center Investment Program — state & local sales/use tax exemption (20 ILCS 605/605-1025; administered by DCEO) (2019-2024 (27 certified data centers; cumulative estimated exemption value)) (Illinois Department of Commerce and Economic Opportunity (DCEO)). Program-wide, not attributable to this site.
Water use
