Reminder of reasons FB IDCC was put on hold

Dear Market Participants,

Following a request for clarifications, CWE TSOs hereby re-explain the reasons that led to the putting on hold of the Flow-based Intraday Capacity Calculation (FB IDCC) project in CWE, as presented to Market Participants during the CWE Consultative Group meeting on 17/04/2019.

CWE TSOs started to work on new Intraday capacity calculation methodologies in Q2 2014, and towards the development of FB IDCC in Q2 2015. Since the beginning, CWE FB IDCC was designed to use the new CGMES standards format defined by ENTSO-E. Despite some mitigation measures, the CWE FB IDCC project could not continue as initially planned due to high risks and uncertainties, and the unavailability of a pan-European CGM creation process in CGMES.

CWE TSOs and NRAs extensively discussed the way forward with FB IDCC, considering the delay in implementation of the CGMES standards, and agreed to put on hold FB IDCC activities within CWE until the CGMES transition is nearly completed, as the implementation of CGMES standards in TSOs’ exchanges is a prerequisite for an optimal FB IDCC solution.

As the CGMES project had a delay of 2 years, CWE TSOs and NRAs concluded that the optimal way forward in matters of costs and time is to wait until the CGMES transition is nearly completed. Once the CGMES transition is near to final, a decision can be reached on whether FB IDCC developments should be continued in CWE or in the CCR Core.

Best regards,
The CWE TSOs
