4. 2. XBID project – Current Status  Joint TSO and power exchange project  15 TSOs across Northern, Western and Central Europe  12 countries from Finland to Portugal  European Power Exchanges (companies like APX, EPEX, Nord Pool Spot and OMIE)  Leading early implementation project for the EU intraday market

5. 5 Required by CACM Article 59, 16 months after CACM entry into force = 14 th Dec 2016 Proposal development facilitated by ENTSO-E, but all TSOs have contributed to the development. Intraday Cross Zonal gate opening and closure times As with other CACM deliverables, the proposal must include an implementation timeline. Public consultation ~ 18 April 2016 to 18 May 2016 3. Intraday Cross Zonal Gate Closure definition

6. - CACM requirements (1) 6 ‘intraday cross-zonal gate closure time’ means the point in time where cross-zonal capacity allocation is no longer permitted for a given market time unit;

7. - CACM requirements (2) 7 One intraday cross-zonal gate closure time shall be established for each market time unit for a given bidding zone border. It shall be at most one hour before the start of the relevant market time unit and shall take into account the relevant balancing processes in relation to operational security.

8. - CACM requirements (3) 8 Gate closure set so that it; -maximises market participants' opportunities for adjusting their balances by trading in the intraday market time- frame as close as possible to real time; and -provides TSOs and market participants with sufficient time for their scheduling and balancing processes in relation to network and operational security.

9. 4. Impact on GB arrangements (discussion) 9 Cross zonal intraday gate closure time defines the last point which orders can be submitted to the pan EU intraday market. It does not define the last point at which orders can be matched. This difference means that interconnector owners will not know the final physical position for those interconnector User BM Units which represent nominated electricity market operators (NEMO i.e. APX and NPS) at the GB gate closure.
