The proposal for the new National Intraday Market has been put in consultation at the beginning of September 2010. • The features of the ID Market, that are in line with the Italian market design, are as follows: • Implicit auction • Market splitting with a zonal structure • Hourly products • The ID market will be based* on 2 sessions in the day D – in each session the tradable hours correspond to 3/4 hours after the gate closure ‘till the end of the day * The timetable of the market is still under discussion
