Solar Mandates and Diminished Discretion: Reviewing Equity Solar v. Grundy County

In this episode of ISACo's Counties Count! Podcast we break down the landmark appellate decision in Equity Solar Illinois v. County of Grundy, which clarifies the limited role of non-home-rule counties in siting commercial solar facilities. The court affirmed that under the 2023 "Solar Amendments," a county must approve a special use permit if the applicant meets all technical state standards, effectively rendering the board’s role ministerial rather than discretionary. This ruling signals that traditional zoning considerations, such as community compatibility or future municipal expansion plans, are no longer valid grounds for denial if state requirements are met. We explore how the "shall be approved" statutory language strips local boards of their traditional legislative authority to block compliant renewable energy projects. Join us as we discuss the significant implications this loss of local control has for county officials navigating Illinois’ aggressive clean energy mandates.
