Chile Wind

Provenance, tier, and validation record for chile-wind. No live curtailment figures on this page — those are on the globe.

Region id: chile-wind
Country: CHL
Waste modality: Wind
Coordinates: 38.50° S, 72.50° W

Measured Data quality

Tier

live · T1a-live-tso

The transmission system operator publishes an hourly series, and the calibration rate comes from the same jurisdiction.

Live TSO feed, own-jurisdiction rate (±2σ from 5-yr backfill, fallback ±15%)

Uncertainty

±15% of peak GW

Regions with a five-year backfill archive use ±2σ of observed annual variance instead of this default fraction.

Published envelope for this tier. See the uncertainty model.

Source provenance

verified · Verified upstream link

The snapshot value comes from a verified upstream feed or anchor.

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 historical backfill parquet yet. The live snapshot now comes directly from CEN monthly wind-reduction workbooks rather than a typical wind profile.

Known limitations

CEN publishes the workbook after month close, so the feed is measured but not real-time. The loader parses the Resumen-DiarioHorario-Eolico wind sheet and sums PE- plant rows into hourly regional reductions. Daily PDF apportionment is currently implemented only for Atacama solar.
