Composite · JPAS tier readings
Power
Power reads 88 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 39 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 74 of 100, sourced evidence. Water measures drinking-water system health, basin stress, streamflow and groundwater conditions.
Real estate / site reads 68 of 100, sourced evidence. Real estate / site measures developable land share, convertible sites, substation hosting and permit velocity.
Environmental reads 51 of 100, sourced evidence. Environmental measures FEMA hazard risk across riverine, coastal, wind, wildfire and related perils.
Labor reads 53 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 95 of 100, sourced evidence. Network measures broadband availability, fiber and middle-mile programs, and exchange-point proximity.

Faraday's Read
Logan County currently sits in a Mixed posture tier with a composite score of 45, though the underlying dimensional breakdown is not populated, leaving the drivers of that score largely opaque. The attribute-evidence roll-up shows a Good quality band (78.88) against Medium completeness (60), with environmental, water, power, network, and labor categories each carrying multiple sourced attributes at 0.85 confidence, suggesting a reasonably solid evidentiary base in those areas. Incentives and regulatory attributes, by contrast, rest on a single estimated-confidence data point apiece, so any read on the county's incentive or regulatory climate should be treated as thin and provisional rather than established. Development density is unscored, no facilities are on record, and the forecast direction is listed as stable but with unscored confidence, meaning the trajectory carries little analytical weight at this time. Overall, Logan County appears to have decent groundwork in the environmental, water, power, network, and labor domains, but the incentive, regulatory, and density pictures remain largely unknown.
