Core CCR – Second amendment of the Day-Ahead Fallback Procedures (CACM Art. 44) - (incl. shadow allocation rules)

Closed 14 Feb 2022

Opened 14 Jan 2022

Results expected 25 Feb 2022

Feedback expected 25 Feb 2022


This consultation concerns the Core CCR Fallback Procedures in accordance with Article 44 of the Commission Regulation (EU) 2015/1222 of 24 July 2015 (CACM).

In cooperation with all other TSOs across Europe, Core TSOs plan to amend the Regional Shadow Allocation Rules for the Core CCR in order to support the planned SDAC Market Coupling daily process optimisation, including envisaged changes of operational timings of the single day-ahead coupling (SDAC) that inter alia result in a shift of the shadow auction results publication deadline from D-1 14h00 to D-1 14h20.

The risk of decoupling situation expected to be significantly decreased due to gained available time window for issue management for the particular daily Market Coupling process. The additional 20 minutes shall be realised from the harmonized NEMO processes (i.e. no time reservation for local second auction in case of a full decoupling as this process only affects some BZs in CCR Core/all CCRs).

For the avoidance of doubt, NEMOs may provide local solutions in case of a full decoupling within the new operational as most NEMOs already apply tailored local solutions without a dedicated pan European time window. Moreover, the deadline of cross-zonal nominations shall continue to be D-1 15h30 as it cannot be further delayed due to the relevant EU regulations. 

Why your views matter

We are seeking input and feedback from relevant stakeholders, market participants, NRAs and NEMOs on our proposal for the second amendment of the Core CCR Fallback Procedures (incl. shadow allocation rules). This consultation is run in accordance with Article 9(13) CACM.
