50Hertz Wind

Provenance, tier, and validation record for germany-50hertz-wind. No live curtailment figures on this page — those are on the globe.

Measured Data quality

Tier

live-domestic-anchored · T1b-live-domestic-anchored

The operator publishes an hourly series, but the calibration rate comes from a domestic statistical agency or a modelled share-split of a national anchor.

Live feed, domestic stat-agency rate (±50% empirical)

Uncertainty

±50% of peak GW

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

Source upgraded 2026-06-25 from ENTSO-E A75 generation × national BNetzA/SMARD rate proxy to direct netztransparenz.de measured renewable redispatch curtailment. Magnitude changed from proxy to measured; the wind/solar split remains estimated via ENTSO-E fuel ratio. Amprion and TransnetBW correctly show near-zero measured curtailment in the May 2026 window — consistent with operational reality (wind/solar curtailment in Germany is concentrated in the 50Hertz and TenneT DE zones).

Known limitations

Wind/solar split is estimated (ENTSO-E fuel ratio) because the netztransparenz feed does not break down Erneuerbar further into wind vs solar. Hence T1b, not T1a.
Single-month window (latest complete calendar month, ~1–2 month settlement lag). Seasonal variation applies.
On API outage, loader falls back to last-good snapshot via withFallback.
