Sweden North

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

Region id: sweden-north
Country: SWE
Waste modality: Wind
Coordinates: 63.50° N, 18.50° 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.

Discrepancy analysis

A direct quantitative discrepancy analysis against published TSO annual curtailment totals is not possible for sweden-north, as no such figures are available in the provided sources. The backfill annual totals are derived using an ungrounded, acknowledged placeholder wind curtailment rate of 1.0%, as detailed in the ENTSO-E Rate Audit (2026-04-24). This placeholder rate is used in the absence of a citable 2023/2024 annual curtailed-energy total for the region. Therefore, a year-over-year reconciliation against external references cannot be performed for this region.

Known limitations

The curtailment rate (1.0% for wind) applied for sweden-north is an acknowledged placeholder. The ENTSO-E Rate Audit (2026-04-24) identified no citable 2023/2024 annual curtailed-energy total from official sources, and thus this rate should be considered an illustrative floor value.
The absence of public TSO annual curtailment figures prevents external validation of the backfill annual totals for this region.
