Power
Power reads 73 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 57 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 68 of 100, sourced evidence. Water measures drinking-water system health, basin stress, streamflow and groundwater conditions.
Real estate / site reads 57 of 100, sourced evidence. Real estate / site measures developable land share, convertible sites, substation hosting and permit velocity.
Environmental reads 38 of 100, sourced evidence. Environmental measures FEMA hazard risk across riverine, coastal, wind, wildfire and related perils.
Labor reads 60 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 92 of 100, sourced evidence. Network measures broadband availability, fiber and middle-mile programs, and exchange-point proximity.

Faraday's Read
Marion County, Illinois currently carries a Mixed posture tier with a composite score of 45, though the underlying dimensional detail behind that score is not broken out in the record. Attribute evidence is moderate in quality and medium in completeness, with environmental, power, water, labor, and network categories each showing multiple sourced attributes at 0.85 confidence, suggesting a reasonably substantiated picture across those areas. By contrast, incentives and regulatory attributes rest on single estimated data points at 0.3 confidence, so any read on tax incentives or regulatory posture should be treated as tentative rather than established. There are no known data center facilities in the county and no operational capacity recorded, and the forecast direction is stable but unscored, meaning near-term trajectory carries little confidence behind it. Overall, Marion County's record is more developed on the physical/infrastructure side than on the policy and incentive side, leaving its investment posture only partially clarified.
