Power Readiness Index
Can the load be delivered here, on time, and at scale? A preview of regional readiness signals for large-load growth: queue exposure, time-to-power risk, and infrastructure constraints across grid regions.

Definitions
- PRI
- Power Readiness Index (0–100). Composite of queue-to-energization conversion, transmission upgrade backlog, transformer & substation lead-time exposure, and large-load concentration. Assessed by EnersynQ from public sources (v0.1). Movements between snapshots follow a documented internal scoring protocol; the scoring formula is not yet published.
- Δ since prior snapshot
- Change in PRI since the prior recorded snapshot (Jul 8, 2026). Snapshots are not evenly spaced and no intermediate values are interpolated; sparklines plot the recorded snapshots by date.
- Est. time-to-power
- EnersynQ estimate (v0.1) of months from interconnection approval to energized load for a large load, not an observed median. The clock starts at approval and excludes time spent in the interconnection queue before approval. Saline Township is withheld (n/a) pending review; all other rows are carried forward from the July 8, 2026 snapshot.
- National PRI Composite
- Equal-weighted mean of the eight region rows; sub-zones are excluded. Composite methodology updated Oct. 1, 2026. Historical National PRI Composite values were restated as the equal-weighted mean of the eight regional PRI rows for consistency and reproducibility. Regional PRI scores were not restated.
- Median est. time-to-power
- Median of the estimates shown in the table; change is measured on the same set of rows.
