Viking Link - NESO's Net Transfer Capacity
Summary
NESO publishes the MW-per-hour restriction values it submits to Viking Link's interconnector capacity calculation, capping GB import/export flows on the 1.4 GW GB-Denmark link. Values appear only when NESO imposes a restriction; absence means no NESO-side cap. Final capacity also depends on the Danish TSO and the cable's own capability.
Why it matters
Transparency on when NESO constrains a merchant-risk interconnector is useful for traders modelling cross-border flows, but this is a reference feed, not a rule change. It exposes the hidden cost of GB-side restrictions that interconnector users bear without pricing them.
Key facts
- •Viking Link: 1.4 GW GB-Denmark HVDC interconnector
- •Values submitted in MW per hourly time period
- •Final capacity is the minimum of NESO value, Danish SO value, and cable capability
- •Empty values mean NESO has applied no restriction

Memo
These are the values submitted by NESO to the interconnector capacity calculation processes which restrict the maximum GB import and export interconnector flows. The values are submitted in MW per hourly time period. ><span style="color: rgb(176,74,42)">NOTE:</span> Final interconnector capacity is calculated using these NESO values, values from the connected SO and the interconnector capability. Therefore, the interconnector’s final capacity value may be lower than the NESO values shown here. The final values can be found on each interconnector’s trading facilitator’s website. Values will only be published where a restriction has been applied by NESO. If there are no values, NESO has not applied a restriction.
