Italy Centre-North Solar

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

Region id: italy-cnord-solar
Country: ITA
Waste modality: Solar
Coordinates: 43.00° N, 12.00° 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

New zone (granularity survey 2026-06-10). Completes Italy's 7-zone partition (was 3 of 7 modelled). ENTSO-E A75 live-probed 2026-06-17 (both B16/B19 non-empty). ±50% T1b envelope pending Terna per-zone confirmation.

Known limitations

The calibration rate is a zone-share of the Terna national anchor, not a Terna per-zone published figure — hence T1b, not T1a. Terna's download center would upgrade this.
