56 05& | Chart 56 Shipper Training Session Capacity Products General There are yearly, quarterly, month-ahead and day-ahead products. Where possible capacity will be bundled. Firm and interruptible capacity will be auctioned Interruptible capacity can be converted to firm capacity Return/surrender of firm capacity is possible* * At the moment not relevant in the Italian market

57 05& | Chart 57 Shipper Training Session Capacity Products General All products are auctioned at predefined (different) points in time that can be found in the auction calendar. The publication of the specific products which will be auctioned takes place in due time before the auction starts (1 month for annual products, 1 week for quarterly and monthly products, no advance publication for day-ahead products). There are two different algorithms for actions: the ascending clock auction algorithm for yearly, quarterly, and month-ahead products and the uniform-price algorithm for day- ahead products. The ascending clock auction takes place in at least one bidding round (is the demand in the first bidding round higher than the capacity offered more bidding rounds will be used). The duration of an ascending clock bidding round is one hour (exception: duration of the first bidding round is three hours) The number of bidding rounds in an ascending clock auction that are needed until an allocation is possible depends on the course of the auction. Day-ahead capacity is auctioned in a single bidding round via the uniform price algorithm Interruptible capacity auctions are optional until NC CAM comes into force and are until then subject to national variations

58 05& | Chart 58 Shipper Training Session Capacity Products Auction types Monthly, Quarterly and Yearly products are auctioned by using an ascending- clock auctioning process Auctioning takes place in (multiple) bidding rounds. In each bidding round a bid for a certain quantity of capacity at a given price is submitted. The price steps are determined by the platform. Day-Ahead products are auctioned in a process using the uniform-price algorithm There is only one bidding round. A shipper can submit up to 10 bids per auction. The platform evaluates all bids in a descending-order according to their price. The lowest price of all awarded bids is considered the clearing price.

64 05& | Chart 64 Shipper Training Session Booking Process Options for booking capacity Two possibilities to book capacities on PRISMA primary: At Interconnection Points (Market area interconnection points and Cross-Border points) firm capacity is marketed via auctions. Interruptible capacity will, until NC CAM comes into force, only be offered by some TSOs via auctions. The German TSOs still offer to book capacities according to the first-come-first- served principle (FCFS) at points to end consumers, production and storage facilities (Grid Access Points). Furthermore, you can book interruptible capacities according to the FCFS principle at German Interconnection Points. Different possibilities to start one of the booking processes: Auction overview : From a list of all available auctions you can directly access the screen for submitting a bid for a certain auction (booking process I) Master data browser for interconnection points: see next slide
