Question 2.1.18 Data field (21) and (22)

In case of an order inserted or a trade executed within the Single Intraday Coupling (SIDC, former XBID) according to the CACM (EU Regulation 1222/2015), should the Contract ID and Contract Name fields report a specific indication?

As SIDC is based on the implementation of a single EU cross-zonal intraday electricity market, both Contract ID and Contract Name reportable fields in the TRUM (data field 21 and 22 in Table 1 of the Annex to Commission Implementing Regulation (EU) No 1348/2014) should have a harmonized structure among different OMPs (NEMOs) that actively join such market.

In the Agency’s view, in case of continuous trading within SIDC both Field (21) and Field (22) should start with the string “SIDC_CO_”. In case of Data Field (21) Contract ID, the prefix “SIDC_CO_” shall be followed by the Contract ID code assigned at centralised level by SIDC.

Let’s consider the following example: NEMO 1 and NEMO 2 are both active members in SIDC, offering their market participants the possibility to join the continuous trading session.
