Turkey (solar)

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

Region id: turkey-solar
Country: TUR
Waste modality: Solar
Coordinates: 37.50° N, 32.50° E

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

Pending: no backfill parquet yet for this region. Once HB.1 / HB.2 land the per-year totals for this region, this section will summarise the Δ vs TSO/Ember/IRENA and flag any year exceeding ±25%.

Known limitations

The public EPIAS dashboard endpoint carries the current day only (probed 2026-08-19: 13 hourly items). The date-ranged API returns HTTP 406 and needs registered TGT credentials the repo doesn't hold, so profile/totalTWh are computed over a partial day, not a 30-day window: totalTWh understates and any data refresh before Turkish sunrise emits an all-zero solar profile. That pre-sunrise zero is a true overnight reading, health-check allowlisted 2026-08-19; a schema break (renamed sun field) throws via the loader's midday silent-zero guard instead. An EPIAS account would unlock the ranged endpoint and a real 30-day window.
