Within-day capacity priced as daily capacity
Currently ‘within-day’ capacity is sold as a daily or rest-of-the-day product, with
either a daily price or an hourly price. The TAR NC does not allow for ‘within-day
priced as daily’. Instead, within-day product pricing depends on the number of
remaining hours in the day, as per Article 14(b).
