Ohio solar permitting
Grade distribution
Overview
Every Ohio county is scored on the SitePath solar permitting index. A handful are graded A or B, meaning they present low to moderate permitting risk for utility-scale solar projects. About half sit in the C range — moderate risk with meaningful process uncertainty. About half are rated D or F — high to very high risk, often due to active moratoria, restrictive setback ordinances, or strong local opposition.
The most favorable jurisdictions in Ohio include Tuscarawas County (grade B), Vinton County (grade B), Hamilton County (grade B). The most challenging include Morrow County (grade F), Madison County (grade F), Clermont County (grade F).
Ohio's RPS framework (RPS 12%) has a mixed effect on local solar permitting: state incentives can accelerate projects, but county boards often act independently of state policy direction. Clermont County currently has an active utility-scale solar moratorium — a hard barrier for project development that typically requires a board vote to lift.

Every U.S. county is scored 0–100 on solar permitting risk (lower is friendlier to development). The grade is a weighted composite of compliance stringency, market saturation, regulatory trajectory, and data uncertainty. Every figure traces back to a primary government document.
