Atacama

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

Country: CHL
Waste modality: Solar
Coordinates: 24.50° S, 69.20° 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 backfill and no TSO anchor. Region relies solely on the live snapshot; nothing to triangulate against.

Known limitations

Cloudflare-gated; live feed via Playwright-Chrome bypass (see src/data/atacama-chile.json.ts). Backfill not yet attempted — would require Playwright-driven archive scrape.
