Dear Members, 

In recent days there have been issues experienced with the running of the Single Day-Ahead Coupling (SDAC) and a number of operational delay messages issued from the trading systems as a result.

These issue have not related to the operation of the local SEM Day-Ahead Market (DAM) but are as a result of issues in other EU jurisdictions.

Given the SEM is now a local DAM, these issues in other European jurisdictions have not had any impact on SEM auction prices or trading except to create some slight delays to the publication of the SEM final DAM auction results.

The issues in the other EU jurisdictions are being investigated.

If you have any further question on this please contact
