County zoning codes often treat these site types differently with respect to setbacks, buffer requirements, and decommissioning obligations. Contact Spark for a site-specific due diligence assessment.

What is the broader data center permitting environment in Illinois?

Illinois operates a retail electricity choice market through ComEd, Ameren Illinois, and MidAmerican Energy territories. The state's Adjustable Block Program provides declining block incentives for solar installations. ComEd offers full retail rate 1:1 net metering, while Ameren provides time-of-use based energy credits. The Climate and Equitable Jobs Act (CEJA) has strengthened the state's renewable energy commitments.
