New Hampshire solar permitting
Grade distribution
Overview
Every New Hampshire county is scored on the SitePath solar permitting index. Nearly every county are graded A or B, meaning they present low to moderate permitting risk for utility-scale solar projects.
The most favorable jurisdictions in New Hampshire include Hillsborough County (grade A), Grafton County (grade B), Rockingham County (grade B). The most challenging include Carroll County (grade B), Coos County (grade B), Belknap County (grade B).
New Hampshire's RPS framework (RPS 25% by 2025) has a mixed effect on local solar permitting: state incentives can accelerate projects, but county boards often act independently of state policy direction. No New Hampshire counties currently have an active utility-scale solar moratorium.

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.
