Milan – 16 th November 2010 Cross Border capacity allocation in 2011: CASC Project

 All TSOs active in the ERGEG Electricity Regional Initiatives of CSE and CWE and Switzerland are committed to actively contribute to the further development and integration of the single European electricity market and to an increasing harmonisation of the cross-border capacity allocation management on borders  TSOs should facilitate the cross-border congestion management processes towards market actors, e. g. by creating a single point of contact, using same IT- tools and aiming for harmonized rules.  This should result in common coordinated congestion management methods and common procedure for the allocation of transmission capacity.  In order to further enhance regional and interregional coordination TSOs have signed a Memorandum of Understanding aiming at the creation of an interregional Joint Auction Office and in a later stage the harmonisation of long term Auction Rules Context

Italian Border Auction Rules for 2011 and associated consultations Due to the expected starting date the 1st April 2011 and to the usual issuing of Auction Rules (AR) per year, two sets of Rules developed:  A first one set of AR for Q1 with same features as for 2010 except for Market Coupling between Italy and Slovenia  A second set of AR starting from the 1st April 2011 with CASC Auction Operator

Auction Rules for 2011 and associated consultations Consultation on Italian Border Auction Rules for 2011 with CASC as Auction Operator is in course since Friday 5 th November 2010 and will finish Friday 19 th November 2010 included. Questions or comments from Participants in English are expected to be taken into account or to be answered before NRAs sending for final approval. All these questions and comments have to be sent to a unique address:

As TSOs intend to delegate to CASC the management of all rights (also already allocated yearly PTRs) from the launch date, consultation on the second set of Italian Border AR and approval by NRAs should be performed before the yearly auctions for 2011 to let Participants be aware of all features before bidding. Consequently, the expected time schedule is: End of public consultation of Italian Border AR on 19 November 2010 TSOs finalise Italian Border AR taking into account comments of Market Participants and send them to NRAs for approval Approval of Italian Border AR by NRAs expected before the yearly auctions for 2011 performed by TSOs On 1 March 2011 CASC starts operation as Joint Auction Office for Swiss Northern Borders On 1 April 2011 CASC starts operation as Joint Auction Office for Italian Borders Aiming at further interregional harmonisation of rules for explicit auctions TSO will work on common Auction Rules of explicit yearly and monthly auctions performed by CASC in 2012 Next steps

Focus on the Auction Rules organization Auction Rules with CASC will include in the border specific appendices some requirements concerning the relationship TSO/Nomination Agent for the scheduling process. Taking this situation into account, the Auction Rules set forth: requirements imposed on the Participant and on CASC related to the Allocation activities > declaration of Acceptance for the Allocation (DoAA) requirements imposed on the Participants and on TSO* related to the Nomination activities > Declaration of Acceptance for the Nomination (DoAN) Consequently, two types of liability are included on the AR: contractual liability of CASC for the performance of the allocation tasks, and contractual liability of some TSO* for the performance of the nomination tasks. * Excepted with RTE as requirements and liability for the Nomination are set in the Import/export Rules to be signed with RTE for the scheduling activities in France

Transfer to CASC of yearly PTRs management PTRs for Italian Borders with delivery dates within the first three months of 2011 will be allocated as today by:  APG, ELES, HTSO, Swissgrid and Terna acting as Auction Operators on behalf of both TSOs (for the direction in export from each respective border)  Terna as Auction Operator for the direction in import and export on the France- Italy border on behalf of both TSOs. Accordingly participants shall comply with the border specific risk management provisions. For PTR allocation with delivery date starting from 1st April 2011, Participants shall comply with CASC new risk management policy: Regarding the specific case of yearly PTRs, Participants owning these PTRs shall provide CASC with 2/12 of the total yearly amount before the monthly auctions for April 2011 (approximately before 18th March 2011).

Overlapping of risk management provisions As a consequence of the transfer to CASC during 2011, at least for yearly PTRs owners and for participants intending to obtain capacity in the monthly auctions for April, overlapping of risk management constraints will exist with on one hand current Auction Office and on the other hand, CASC. Example: –Participant A obtained in the direction France to Italy 100 MW for all 2011 at 11 €/MWh (per month, the amount to be paid is 803 k€) –For the first three months, Bank Guaranty (BG) with TERNA should be set at 803 k€ (+ monthly and daily debts) as minimum value and this BG should be kept by TERNA at least until May 2011 to cover daily PTR settlement –To be entitled with CASC, the Participant shall credit CASC bank account with 1,6 M€ not later than middle of March 2011

Forum with all Participants The present SG meeting mainly deals with main issues related to the CASC project during the consultation phase on the Italian Border Auction Rules An additional specific forum involving all interested market players will be organized beginning of 2011 in order to deal with all technical issues and facilitating the transition towards CASC. This forum will be occasion to discuss deeper: Process to be entitled with CASC IT requirements with CASC Financial provision with CASC … … and to collect expectations from Market players.

Analysis of impacts if we success to transfer yearly to CASC from 1st April 2011 The overlapping between Bank Guarantee provided to TSOs and the Bank Account given to CASC has not an huge impact on Users. The full payment of Yearly PTRs for Jan, Feb and Mar in January (payment in advance) CASC should invoice Yearly PTRS for April in May 2011 (payment ex-post) Users can riduce the Bank Guarantee with TSOs before deposit money on CASC Bank Account 1st April 2011 Go Live CASC expire of Bank Guarantee Live CASC
