Alaska Railbelt
Provenance, tier, and validation record for alaska-railbelt. No live curtailment figures on this page — those are on the globe.
- Region id
alaska-railbelt- Country
- USA
- Waste modality
- Mixed
- Coordinates
- 61.20° N, 149.90° W
- Tier
estimated· T3-modelledNo waste figure: no curtailment series is collected for this grid and none is modelled, so the globe shows it as a grid marker without a waste pillar. The T3 label only records that nothing here is measured.
- Uncertainty
- None
No waste figure, so there is no envelope to publish.
- Source provenance
modelled-fallback· No verified upstream linkThere is no verified upstream link, and no waste figure is served for this grid.
- Source
- Chugach/MEA/GVEA/HEA isolated Railbelt. No public hourly series. Grid present, ops unpublished.
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.

Source
- Region id:
alaska-railbelt - Country: USA
- Tier: estimated
- Kind: mixed
- Source: Chugach/MEA/GVEA/HEA isolated Railbelt. No public hourly series. Grid present, ops unpublished.
- Source URL: https://rca.alaska.gov/
- Loader: (see region source / TSO-grid completeness loaders)
- Structural gap: no
- Waste status: unpublished unless the operator publishes a curtailment/spill series. Missing ≠ zero. Live generation does not make waste T1a.

Discrepancy analysis
Grid-completeness row. Waste is unpublished unless a later loader adds a published series. Do not read a zero profile as a measured finding.
