NemoLink - NESO's Net Transfer Capacity
Summary
NESO publishes the Net Transfer Capacity values it submits for NemoLink interconnector capacity calculations, showing GB import and export limits in MW per hour. These values restrict maximum flows but final capacity may be lower after combining with French TSO values and physical interconnector capability. Values are only published when NESO applies restrictions.
Why it matters
This data transparency allows market participants to understand when GB transmission constraints limit interconnector trading capacity, as distinct from French network limits or cable capability. The publication reveals when internal GB bottlenecks reduce cross-border arbitrage opportunities.
Key facts
- •Data shows MW capacity restrictions applied by NESO per hourly period
- •Final capacity calculated using NESO values, connected SO values, and interconnector capability
- •Values only published where NESO restriction applied
- •NemoLink connects GB to France

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. >\*\*NOTE:\*\* 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.
