Montana solar permitting

Most counties at low to moderate risk A handful at high risk No active solar moratorium
State policy: RPS 15% by 2015

Grade distribution

ABCD

Overview

Every Montana county is scored on the SitePath solar permitting index. Most counties are graded A or B, meaning they present low to moderate permitting risk for utility-scale solar projects. A handful sit in the C range — moderate risk with meaningful process uncertainty. A handful 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 Montana include Jefferson County (grade A), Broadwater County (grade A), Garfield County (grade A). The most challenging include Gallatin County (grade D), Lewis and Clark County (grade D), Missoula County (grade D).

Montana's RPS framework (RPS 15% by 2015) has a mixed effect on local solar permitting: state incentives can accelerate projects, but county boards often act independently of state policy direction. No Montana 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.
