Illinois statutes provide that a municipality or county may regulate wind farms within its zoning jurisdiction and within the 1.5 mile radius surrounding its zoning jurisdiction. A county or municipality may not require a wind tower or other renewable energy system that is used exclusively by an end-user to be setback more than 1.1 times the height of the system from the end-user's property line. A setback requirement imposed by a municipality on a system may not be more restrictive.

There must be at least one public hearing not more than 30 days prior to a siting decision by the county board. Notice of the hearing must be published in a newspaper of general circulation in the county.
