Research Around SDAC Fallback Concept

Research Around the Fallback Concept for the Single Day-Ahead Coupling (SDAC)

TSOs and NEMOs have been asked to assess an alternative fallback mechanism for SDAC in which intraday continuous trading (SIDC CT) would be used both for capacity allocation - replacing Shadow Auctions - and for determining the SDAC reference price in cases of full decoupling or partial decoupling of all NEMOs within a bidding zone (i.e., when calculating the SDAC price is not possible).

 

The details of this concept were presented at the most recent MCCG meeting and are available on the ENTSO-E and NEMO Committee websites. To gather feedback from market participants, TSOs and NEMOs have prepared a survey focusing on this topic, where participants will also find concrete information on the proposal itself.
