Power
Power reads 69 of 100, sourced evidence. Power measures grid capacity, interconnection-queue depth, generation mix, retail price and substation density. Interconnection-queue depth is an estimated roll-up (EST); queue vintage PJM 2026-04-28, CAISO 2025-02-12.
Politics
Regulatory reads 100 of 100, sourced evidence. Regulatory measures air-quality designation under the Clean Air Act and commercial permitting activity. Regulatory is evidenced by air-quality designation and permitting activity; a county absent from EPA's nonattainment list reads as attainment. Attainment here is by absence of an EPA designation; EPA's county list is complete, so absence reads as attainment.
Community reads 61 of 100, sourced evidence. Community measures enacted moratoria, pending legislation and farmland share as signals of local consent.
Incentives reads 100 of 100, estimated evidence. Incentives measures state program baselines and disclosed awards for data-center and industrial projects.
Resources
Water reads 69 of 100, sourced evidence. Water measures drinking-water system health, basin stress, streamflow and groundwater conditions.
Real estate / site reads 51 of 100, sourced evidence. Real estate / site measures developable land share, convertible sites, substation hosting and permit velocity.
Environmental reads 81 of 100, sourced evidence. Environmental measures FEMA hazard risk across riverine, coastal, wind, wildfire and related perils.
Labor reads 54 of 100, sourced evidence. Labor measures electrician depth, wages, unemployment and prevailing-wage floors in the county labor market.
Connectivity
Connectivity is not yet activated as a brief section; the Network tier reading is shown.
Network reads 89 of 100, sourced evidence. Network measures broadband availability, fiber and middle-mile programs, and exchange-point proximity.

Faraday's Read
Brown County, Illinois currently sits in a Mixed posture tier with a composite score of 45, reflecting a moderate overall standing rather than a clear strength or weakness. The underlying evidence base is fairly substantial for a county-level record, with sourced attributes (0.85 confidence) covering environmental, labor, network, power, and water categories, giving reasonable grounding to those dimensions; incentive and regulatory attributes, by contrast, rest on only estimated data (0.3 confidence) and should be treated as thin and uncertain. Overall evidence quality is rated Good at 73.18, while completeness is Medium at 59, meaning the picture is reasonably reliable where it exists but still has gaps. There are no known data center facilities recorded in the jurisdiction, and the forecast direction is stable, though that forecast itself carries no confidence rating and should not be read as a strong signal. Development density (jds) is unscored, so the county's actual buildout activity relative to peers remains unknown.
