Indiana

Grade distribution

Overview

Indiana has 92 counties tracked in the SitePath solar permitting index. 20 (22%) are graded A or B, meaning they present low to moderate permitting risk for utility-scale solar projects. 41 counties sit in the C range — moderate risk with meaningful process uncertainty. 31 counties are rated D or F (34%) — high to very high risk, often due to active moratoria, restrictive setback ordinances, or strong local opposition.

The most favorable jurisdictions in Indiana include Ripley County (grade B), Washington County (grade B), Benton County (grade B). The most challenging include Boone County (grade F), Putnam County (grade F), Decatur County (grade F).

Indiana'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. 2 counties — Putnam County, Decatur 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.

About SitePath scoring

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.
