Dear Members, 

There have been 2 major incidents whereby partial decoupling has been triggered in MRC during the past two years, and as such a training session has been organised by the Single Day Ahead Coupling (SDAC) parties providing all market participants with the ability to observe a full decoupling scenario occur in a simulation environment. 

The objective of this session is to provide market participants with the opportunity to test that internal processes align with the actual MRC outputs when full decoupling may occur. 

This training session has been scheduled for 30th September, if you are interesting in partaking in this training session you must register your interest (to by 18th September. 

We are aware of the parallel trialling of ETS 3.4.6 and this decoupling scenario. These are separate trials and both are non-mandatory for participation. 

If you would like further information regarding the background to this session, please refer to the information document provided by SDAC or submit your query to SEMOpx at
