50Hertz Solar

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

Region id: germany-50hertz-solar
Country: DEU
Waste modality: Solar
Coordinates: 52.00° N, 12.50° E

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 proxy (generation × national BNetzA/SMARD rate) to direct measured renewable redispatch curtailment from netztransparenz.de. See germany-50hertz-wind for full notes.

Known limitations

Wind/solar split is estimated (ENTSO-E fuel ratio) because the netztransparenz feed does not break down Erneuerbar further. Hence T1b, not T1a.
Single-month window with ~1–2 month settlement lag.
