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

Region id: iran
Country: IRN
Waste modality: Solar
Coordinates: 33.00° N, 52.00° E

Estimated Data quality

Tier

estimated · T3-modelled

No 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

modelled-fallback · No verified upstream link

There is no verified upstream link. The snapshot is a typical-shape profile scaled to an anchor, or otherwise estimated.

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 public hourly archive. The TAVANIR (tavanir.org.ir) public site is reachable but opaque — it does not expose hourly solar curtailment, and sanctions-era data restrictions further limit upstream access. The loader emits a typical solar shape (peak UTC 7) scaled to a ~0.3 TWh/yr anchor for Yazd / Kerman large-PV curtailment in southern Iran. T3-modelled, ±40% envelope. There is no specific Iran item in docs/known-limitations.md — Item 14 enumerates the other Middle East coverage-first fallbacks (Jordan, Saudi solar, UAE, Oman, Israel) but Iran sits outside that group as a sanctions-data-opacity case rather than a private-grid case. Anchor revision welcome if a public TSO source emerges.
