South Carolina

Grade distribution

Overview

South Carolina has 46 counties tracked in the SitePath solar permitting index. 16 (35%) are graded A or B, meaning they present low to moderate permitting risk for utility-scale solar projects. 20 counties sit in the C range — moderate risk with meaningful process uncertainty. 10 counties are rated D or F (22%) — high to very high risk, often due to active moratoria, restrictive setback ordinances, or strong local opposition.

The most favorable jurisdictions in South Carolina include Marion County (grade B), Union County (grade B), Edgefield County (grade B). The most challenging include Sumter County (grade D), Beaufort County (grade D), Spartanburg County (grade F).

The state's policy environment — No binding RPS — presents headwinds for renewable development, making county-level permitting conditions especially important to evaluate project by project. No South Carolina counties currently have an active utility-scale solar moratorium.

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.
