65 ILCS 5/11-42-15

For electric generating wind devices other than those with a nameplate generating capacity of less than 100 kilowatts that are used primarily by an end user, a municipality may prohibit any electric generating wind device from locating within its corporate limits, provided that the regulation is not inconsistent with another municipality's zoning regulation. This Section shall apply only to electric generating wind devices permitted after the effective date of this amendatory Act of the 98th General Assembly.
