Hawaii (Big Island)
Provenance, tier, and validation record for hawaii-island. No live curtailment figures on this page — those are on the globe.

- Coordinates
- 19.60° N, 155.50° W
- Tier
estimated· T3-modelledNo live feed and no published total for this region. A typical-shape profile is scaled to a capacity-based or literature anchor.
Modelled profile, scaled to annual (±40%)
- Uncertainty
- ±40% of peak GW
Published envelope for this tier. See the uncertainty model.
- Source provenance
official-lead· Official source identified, live path not producingAn authoritative source exists and the loader is wired or scaffolded, but the live path is not producing usable data — geoblocked, auth-gated, or parser pending. The emitted snapshot falls back to modelled or last-good values.
- Source
- Hawaiian Electric historical curtailment XLSX 2026-05-09: Hawaii Island 2024 = 1.9 GWh curtailed from curtailable renewables. Annual file only — no daily/monthly programmatic feed. T1 not achievable.
Tier, provenance, and source are read at build time from src/lib/regions.ts — the same table the globe draws from. The validation record below is generated separately and gated against it by npm run ci:docs-drift.

Discrepancy analysis
No backfill and no TSO anchor. Region relies solely on the live snapshot; nothing to triangulate against.
Known limitations
No region-specific limitations recorded. See docs/methodology/historical-backfill.md §"Known limitations" for cross-cutting notes.
