Overview

Maryland has 24 counties tracked in the SitePath solar permitting index. 6 (25%) are graded A or B, meaning they present low to moderate permitting risk for utility-scale solar projects. 11 counties sit in the C range — moderate risk with meaningful process uncertainty. 7 counties are rated D or F (29%) — high to very high risk, often due to active moratoria, restrictive setback ordinances, or strong local opposition.

The most favorable jurisdictions in Maryland include Prince George's County (grade B), Montgomery County (grade B), Howard County (grade B). The most challenging include Calvert County (grade D), Garrett County (grade D), Harford County (grade F).

At the state level, Maryland's RPS 50% by 2030 commitment creates a supportive macro environment for solar development, though county-level boards retain significant discretion over individual project approvals. No Maryland 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.
