Iowa solar permitting
Grade distribution
Overview
Every Iowa county is scored on the SitePath solar permitting index. More than half are graded A or B, meaning they present low to moderate permitting risk for utility-scale solar projects. A sizeable minority sit in the C range — moderate risk with meaningful process uncertainty. A minority 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 Iowa include Polk County (grade A), Scott County (grade A), Wapello County (grade B). The most challenging include Linn County (grade D), Cerro Gordo County (grade F), Clarke County (grade F).
Iowa's RPS framework (RPS on file · no % target) has a mixed effect on local solar permitting: state incentives can accelerate projects, but county boards often act independently of state policy direction. Cerro Gordo County, Clarke County currently have active utility-scale solar moratoria. These represent hard barriers where project approvals are unlikely until the moratorium is lifted by county vote.

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.
