Summary
County legislative staff warned an energy omnibus will give the Illinois Commerce Commission increased authority over local siting disputes and that the bill includes battery‑storage incentives and tighter diesel backup limits. Committee members spent substantial time debating data centers’ energy and water demands and asked staff to study closed‑loop cooling, local infrastructure limits, and economic tradeoffs.
James Sherwood told the legislative committee that the energy omnibus passed late in veto session and is expected to be signed by Governor Pritzker. He said the bill shifts some authority to the Illinois Commerce Commission (ICC) through an integrated resource planning process and creates state support for battery storage and expanded energy‑efficiency goals.
"The thought is that the Illinois Commerce Commission...can react quickly," Sherwood said, describing the bill's move of certain planning authority to the ICC. He also warned the committee that the ICC's adjudicatory role may favor projects that add generation, noting that the bill limits how far local governments can use zoning or other measures to block renewable projects and that disputes between developers and local units of government may now be resolved by the ICC.
Committee members raised concerns that those provisions would erode local control. One member said the county must "speak with one voice when it comes to matters dealing with the legislature," and several urged clearer messaging through the county's lobbyists.
Members then turned to the growing number of proposals for hyperscale data centers. The committee discussed the centers' large electricity demands and water‑use implications. Sherwood said a spring proposal that would have required very large new loads (including data centers) to install on‑site renewables was removed from the final package; a remaining provision would require cleaner technology for backup diesel generators.
Committee members asked staff to collect data on local interest in unincorporated areas, to invite experts on closed‑loop cooling and water reuse, and to analyze local infrastructure constraints. Members also debated economic tradeoffs: one county official noted that while data centers bring property and utility tax revenue, they often produce relatively few long‑term local jobs compared with the amount of electricity and water they consume. The committee agreed to schedule a deeper, staff‑led discussion on data‑center siting, infrastructure and mitigation strategies in a future meeting.
