2026 State Solar Permitting Rankings

Every state ranked by the median risk score across its counties. Lower is better — a lower median means more of the state's counties lean toward permissive conditions for utility-scale solar. The ranking covers all 50 states; D.C. is excluded (single-county jurisdiction). State RPS policy tier is shown for context but is not a component of the score.

The Texas finding: Texas has a hostile state RPS policy and the best median county permitting score in the country — 28.8, with 95% of its 254 counties graded A or B. Local county economics (property tax revenue, landowner lease income, limited organized opposition) are driving permitting outcomes that state policy would not predict. This is the clearest example in the dataset of why state-level policy tier is context, not signal.

How to read this ranking

The median score is the midpoint across all a state's counties — half score above, half below. It's a better summary statistic than the mean here because a small number of very high-risk counties (moratoria, outright bans) would otherwise skew the average upward.

The grade distribution bar shows the share of counties in each grade band — green left, red right. A bar that's mostly green indicates a state where most counties are low-to-moderate risk. A bar with significant orange or red on the right indicates meaningful pockets of resistance, even if the median score looks acceptable.

The A/B percentage is the most practical number for site selection: it tells you what fraction of the state's counties are working with, not against, a solar developer at the ordinance level.

Notable patterns in the data

The Midwest bifurcation. The Midwest has the highest rate of A/B counties among major regions (84%) but also the most active moratoria (21 of the national total of 26). It's the most polarized region: large portions of Iowa, Indiana, and Kansas are permissive — until they aren't. The farmland-versus-solar conflict is playing out in concentrated patches rather than across a broad front.

West Virginia at the bottom. West Virginia has only 15% of its 55 counties in the A/B range — the worst ratio among the contiguous 48 states. The state's coal and gas heritage and the absence of a meaningful RPS framework have produced a county-level environment that is broadly resistant, not just patchily so.

New England is more permissive than it looks. Vermont, New Hampshire, Connecticut, Massachusetts, and Rhode Island all rank in the top 10 nationally. Small county count limits statistical noise, but these states have taken an ordinance path (limited municipal solar restrictions, strong state preemption) that reduces local friction even where community opposition exists.

State policy tier reflects the state's Renewable Portfolio Standard framework: Favorable = strong RPS target; Hostile = no RPS or active anti-renewable legislation; Neutral = weak or partial RPS. Policy tier is not a scoring input — it is context only.

Methodology note

Scores are computed using SitePath's V2.3 formula: 33% Compliance Stringency + 23% Market Saturation + 24% Regulatory Trajectory + 20% Data Uncertainty. Counties with active utility-scale solar moratoria are capped at score 100 (grade F). State rankings use the median of county scores within the state. Full methodology →
