(15 companies/associations have answered)
presented during a forum the 13th March in Rome
(100 participants coming from 60 companies)
Following the consultation, the XBID Auction Rules have been finalized and forwarded to the NRAs for approval. Additionally, a document gathering all remarks received during the consultation and the TSOs answers has been attached to.
CRE, ELCOM and AEEG have approved the XBID Auction Rules. Approval process from the Slovenian and Austrian regulators is still in progress.

3. Consultation – Remarks and answers synthesis
XB ID Interim solution on the North Italian Borders
Consultation – Remarks and answers synthesis
Fifteen (15) companies or associations answered to the consultation of the ID Rules.
The main comments raised were the following:
1) Pb with new Timing of daily nominations at 12:45 > interferences with CWE market coupling
TSOs propose to postpone the timing of the entire process of XBID1 for 10’ in order to facilitate the possibility for Market Participants to consider CWE MC results for defining their daily nominations.
2) Cross border traders restrictions > suppression of access to MI1 and no access to MI3
TSOs propose to allow the participation in MI1, MI2 and MI3 to all virtual units (UPV/UCV) related to cross border activities. However, the anticipation of the MI1 cannot be possible so as to have results of MI1 for adjusting daily nomination.

3) UIOLI Principle > ask for the introduction of UIOSI principle
The UIOLI mechanism has been chosen to facilitate the implementation of an intraday mechanism which is an interim mechanism. Furthermore it ensures that the capacity will be acquired by the participants that really need it for a physical delivery and not for financial optimization.
4) Timing of 1st XBID auction > ask for a postponement
The timing proposed is a compromise between the requirements of the TSOs and those of the Market Parties, being the only one feasible that allows the bidding on the MI2 that is the last session of the Italian market that covers the whole day
The complete list of comments, including the answers of TSOs, will be published on CASC website together with the XBID Auction Rules.
