For using Intraday Capacity CH-IT, nominations at Swissgrid are not required

The BG-R will get an modified or imposed Time Series on his day ahead A:A relationship Nominations in an Intermediate Confirmation Report (ICNF) from Swissgrid after receiving the intraday CAS from Terna.

This modified or imposed Time Series has to be included in all further intraday schedule messages sending to Swissgrid for this specific day.

New Version of the “Technical Balance Group Regulations” will be placed on Swissgrid Website in April 2012

This new version of the “Technical Balance Group Regulations” will come into force on the 30th of Mai 2012 at the expected go-live date of this ID CH-IT project

APG and Terna are working together to change the matching process of the scheduling on their common border.

The new matching process is based on the SO-SO approach defined by the UCTE (now ENTSO-E) and already in use in the Central-East Europe region.

The intra-day mechanism on this border will start only after the implementation of the new matching process. The date of the go-live is expected by the end of 2012.

Further information about the new matching process and the intraday mechanism will be provided in due time before the go-live.

The SO-SO matching approach will be extended in a second step also on Slovenian-Italian border
