Hungary Wind

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

Region id: hungary-wind
Country: HUN
Waste modality: Wind
Coordinates: 47.70° N, 17.50° 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

Structurally tiny signal: Hungary's wind fleet is frozen at ~330 MW by the 2016 permitting ban, and the modelled proxy (A75 B19 × 1%) peaks ≤ 2.3 MW on the windiest hour (live probe 2026-08-19: 716/716 nonzero points, max 225 MW). The 30-day time-of-day profile flickers around the health check's 1 MW zero-peak floor, so the region is allowlisted there (2026-08-19) — the zero is a true reading of a live feed, not a breakage.
