Feasibility Study of Italy-France Cross-Border Intraday Trading
A technical feasibility study conducted during the CSE SG Group meeting in Rome on May 15, 2012, explored the cross-border intraday trading between Italy and France. The study highlighted the current challenges, high-level requirements, IT needs, and clearing processes for implementing a continuous trading mechanism. Various aspects such as implicit auctions, capacity allocation, and congestion management were discussed to enhance the cross-border trading experience. The process involves transferring Italian bids into MI auctions and matching them in cross-border transactions.

Italy-France Cross-border Intraday: Technical feasibility study CSE SG Group meeting Rome, 15 May 2012
Agenda Background High level requirements IT requirements Clearing and Financial settlement
Background No intraday tool currently in place on the Italian-French border Interim solution: TSOs (TERNA-RTE) are going to activate an explicit intraday auction to allocate the XB transmission capacity remaining to previous auction sessions. Current Italian and French intraday markets Italian intraday market French intraday market Implicit auctions: 2 auctions in D-1 2 auctions in D Continuous trading Target model on cross-borders trading in respect of ACER s Framework Guidelines on Capacity Allocation and Congestion Management Preference for implicit continuous trading Embedding a criteria for the pricing of the XB ID allocated capacity EPEX Spot and GME carried a study to analyze possible solutions and features to connect France and Italy ID markets with a continuous trading mechanism
Agenda Background High level requirements IT requirements Clearing and Financial settlement
High level requirements Italian intraday market French intraday market 4 Implicit auctions: Mandatory for participants to be balanced in the Italian ID market Continuous trading Continuous cross-border trading, taking into account available cross border capacities Before gate closure of Italian IDM Auctions, Cross-border trades for corresponding hours are transferred into the Italian auction French-Italian cross-border order book is closed for hours which cannot be traded in a later Italian MI auction GME is counterpart for Italian bids; ECC (EPEX CCP) is counterpart for French bids; GME and ECC manage the settlement of the XB trades OTC cross-border implementation subject to a common position from both regulators
Continuous XB platform linked with Italian implicit auctions Intraday Cross Border trading system(SOB) Bids Bids EPEX members Bids GME information Capacity Italian Members registration Order Capacity information CMM TSO information Capacity TSO Italian intraday auction Order registration OTC ?
Process: Italian bids transfered into MI auctions Italian bids matched in the cross-border intraday market are transferred into the subsequent MI auction as bids and offers according to the following criteria: Purchasing bids in the cross border market are transferred into the MI auction as selling offers (and vice versa) Bids and offers are located in the virtual France zone of the Italian MI auction Price at which the matched order in the cross border market is transferred in the in the MI auction is either: freely set by the market participant set as market price (zero for selling offers and no indication of price for purchasing bids) set equal to the price of the matched order in the cross-border market In case the bids/offers transferred to the Italian MI auction is not matched (lack of liquidity or not competitive price) the Italian market participant is unbalanced in the Italian market As currently happens to Yearly, Monthly and Daily PTRs holders that nominate cross-border flow and are unable to sell/buy energy on the Italian day-ahead market Firmness of the cross border nomination is independent from the local nomination process and in any case ensured
Price limits Italian MI auction and in the French ID market have different price limits: 0 /MWh; 3.000 /MWh in the Italian MI market -9.999 /MWh; +9.999 /MWh in the French ID market Suggestions: 1. Restrictive: Adoption of different price limits for Italian and French market participants in the cross-border market without allowing cross-border matching, in case prices on French side exceed Italian price limits (Italian participants are prohibited to buy and sell at negative price and at prices over 3000 /MWh in the XB ID market) 2. Less restrictive: Italian participants can be allowed to buy and sell at negative price and at prices over 3000 /MWh in the XB ID market Price limits of Italian MI auctions would not be changed Impact on definition of price to which XB ID trades are transferred into Italian ID auction, as described in slide 7
Timeframe French-Italian Xborder continuous trading 15h D-1 French Intraday continuous Order submission and matching Xborder trading closed for H13-H16 7h30 - x 11h30 - x Italian-French Intraday Cross-border continuous Order submission and matching Italian Intraday 4 Mi auctions
Timeframe issues Under current EPEX SPOT and GME MI timing, only delivery hours from the 13th to the 24th would be tradable on a continuous cross border intra-day Overlap between delivery hours in MI auctions. For example, MI3 regards delivery hours from the 13th to the 24th hour, and MI4 regards delivery hours from the 17th to the 24th hour. To be decided whether FR-IT intraday trades sent to GME MI auctions are: all the recent trades on the continuous platform not sent yet in a previous MI auction, or only the trades regarding the hours for which trading is closed, e.g. delivery hours from the 13th to the 16th hours at the MI3 auction
Italian virtual zones France is a virtual zone of the Italian market France is directly connected to North zone with an infinite ATC Only PTRs holders are allowed to place their bids in the France zone France virtual zone is always cleared with the same zonal price as the North one and the ATC can never get congested France and North zones, in the Italian market, can be considered as a unique zone, from a market perspectives (prices, competition among market players) Connection with Southern zones with France: Italian importers locate their bids in the French virtual zone. These bids are matched with other Italian bids, located in all Italian zones, subject to the market splitting mechanism, respecting Italian internal congestion (ATC)
Agenda Background High level requirements IT requirements Clearing and Financial settlement
IT requirements Shared Order Books /Congestion Management Module System (SOB/CMM) in order to allow that, provided that there is available capacity: Order books have to be updated simultaneously according to the capacity values sent to the SOB/CMM Bids submitted to one local order book are simultaneously shown on the other order books provided they are compatible with the updated values of XB capacity There is a perfect synchronization of all order books Cross matching of bids submitted to different order books is supported Time stamp of the bids is similar (crucial to correctly manage priority of bids with same price) Both order books would be hosted in the same platform: Market A Market B Buy Buy Sell Sell ATC P:50MW@70 S:25MW@70 P:50MW@70 S:25MW@70 60 P:25MW@65 S:50MW@75 P:25MW@65 S:35MW@75 P:30MW@60 S:20MW@80 P:45MW@60 S:20MW@80 With 60 MW capacityfromA to B 60 MW cheapest sell orders in A are shown in B 60 MW most expensive buy orders in B are shown in A
