Please be informed that, following the approval of the relevant NRAs, the amended version of the Nemo Link Access Rules has been published on our website.
The relevant sections on our website have also been updated with the Access Rules’ subset parts accordingly:
The amended allocation rules include the following changes:
- Market Time Unit (MTU):
Introducing MTU-based approach for Day-Ahead (DA) and Intraday (ID) rules to allow future flexibility (e.g. moving from hourly to 30-minute MTUs). A copy of the Market Time Unit (MTU) Application can be found here.
- Firmness After Day-Ahead Firmness Deadline (DAFD):
Removing “emergency situation” as a curtailment scenario after the DAFD in Long-Term (LT) and Day-Ahead (DA) rules, strengthening physical firmness for capacity holders. Intraday rules remain unchanged.
- Loss-Adjusted Day Ahead Market Spread (LADAMS) Calculation:
In the event of capacity curtailment before the Day-Ahead Firmness Deadline (DAFD), the compensation issued by Nemo Link to Market Participants would be Loss-Adjusted Day Ahead Market Spread (LADAMS). Nemo Link have adjusted the LADAMS calculation to reflect 15-minute MTU prices under Single Day-Ahead Coupling (SDAC).
- Fallback auction:
Removing fallback auction based on default bids in the DA rules.
- General Clarifications & Housekeeping:
Updating NESO’s legal name, improving grammar, Introducing “contestation period” definition for clarity
- Harmonised Allocation Rules (HAR) Alignment:
Ensuring consistency with the HAR 2024 and HAR 2026 version.
The amendments will come into effect for capacity delivered from 1st of September 2026.
We remain at your disposal in case of any question.
