Provider notes
Energy. Served by a ComEd substation off Eldamain Road; full power allocation still pending ComEd approval. The annexation agreement prohibits on-site nuclear generation. No confirmed on-site generation.
Water. Air-cooled closed-loop system uses ~42,500 gallons/day (Shaw Local, 2026-03-12), revised down from an original 350,000 gpd proposal; "no municipal water will be used for cooling."
Community. Two active lawsuits as of July 2026. (1) John Bryan (filed Oct 28, 2025): a conditional settlement was before the June 23, 2026 City Council — terms limited to a phasing-order revision (NE-SE-W instead of NE-W-SE), no monetary payment to Bryan. (2) Preserve Our Yorkville & Community LLC (filed April 2026): broader suit alleging inadequate annexation/rezoning notice and deviation from the 2016 Comprehensive Plan; still ongoing as of June 30, 2026. Pioneer Development also sought an 18-month extension (to Dec 31, 2027) to close on all parcels — failure voids the annexation agreement. …
