Question 5

What should data center developers know about greenfield and brownfield site selection in Marshall County?

Accepted Answer

Site type significantly affects data center permitting in Marshall County.

Brownfield or previously developed sites can offer faster approvals and lower opposition risk, but may carry remediation requirements. 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.

Question 6

What is the broader data center permitting environment in Illinois?

Accepted Answer

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. See the full Illinois state guide for statewide incentives, net metering rules, and interconnection requirements.
