Project Cardinal Data Center Campus

Pioneer Development. Approved. 1800 MW.

Pioneer Development's Project Cardinal is a planned 14 building, 1,037 acre data center campus northwest of Illinois Route 47 and Galena Road in Yorkville, described locally as larger than Central Park. The Yorkville City Council approved annexation and rezoning in November 2025 and a development agreement on March 10, 2026, with roughly 51 million dollars in upfront payments. In April 2026 residents sued, alleging the rezoning skipped required environmental review and public notice, and in June 2026 the developer asked for an 18 month extension to finish buying all the needed parcels.

What it would mean nearby

The cooling design has not been reported. If it uses evaporative cooling, a 1800 MW facility would draw roughly 5.7 million to 20.5 million gallons of water a day, about what 65,600 households use.

This case does not change what a household pays today, but it is the main tool Illinois regulators are using to try to stop the cost of new grid equipment for data centers from landing on residential bills. ComEd annual reconciliation rate case (docket 25-0383) adds about $3.10 a month to a typical bill from January 2026. PJM capacity auction price spike hits ComEd supply charges adds about $10.50 a month to a typical bill from June 2025.
