Composite · JPAS tier readings
Power
Power reads 24 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 81 of 100, sourced evidence. Community measures enacted moratoria, pending legislation and farmland share as signals of local consent.
Incentives reads 25 of 100, estimated evidence. Incentives measures state program baselines and disclosed awards for data-center and industrial projects.
Resources
Water reads 31 of 100, sourced evidence. Water measures drinking-water system health, basin stress, streamflow and groundwater conditions.
Real estate / site reads 84 of 100, sourced evidence. Real estate / site measures developable land share, convertible sites, substation hosting and permit velocity.
Environmental reads 78 of 100, sourced evidence. Environmental measures FEMA hazard risk across riverine, coastal, wind, wildfire and related perils.
Labor reads 45 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 76 of 100, sourced evidence. Network measures broadband availability, fiber and middle-mile programs, and exchange-point proximity.

Faraday's Read
Petroleum County, Montana carries a Favorable posture tier with a composite score of 70, though the underlying dimensional detail behind that score is not broken out in the data. The attribute evidence base is moderate in quality (58.4) and medium in completeness (53.33), with environmental, water, network, labor, and power categories each showing sourced-level confidence (0.85) across a reasonable spread of attributes, while incentive and regulatory categories rest on just one attribute apiece at only estimated confidence (0.3), leaving those areas thin. No data center development density score is available, and there are no known facilities, operational sites, or megawatts recorded in the jurisdiction. The posture forecast points to a stable direction over a six-month horizon, but this forecast itself is unscored for confidence, so it should be read as a placeholder rather than a firm signal. Overall, Petroleum County presents as a jurisdiction with reasonably well-sourced environmental and infrastructure attributes but a still-developing record on incentives, regulation, and actual project activity.
