5. CAM Progress & Next Steps  CAM Code undergoing internal review and change  Stakeholder feedback being considered by ENTSOG  Ongoing discussions with ACER as to potential changes  ACER requested revised Code to be sent back by 17 th Sept  To keep the Commission’s deadline for the start of Comitology beginning end of Dec 12  ACER plan a workshop on 19 th Sept to discuss opinion and revised CAM version  Madrid Forum 20 th Sept – CAM most likely to be an agenda item.  Further information please contact matthew.hatch@nationalgrid.commatthew.hatch@nationalgrid.com

6. Constraint Management Principles (CMP) Update  CMP approved by Member States at the Comitology meeting on 20 th April 2012  Now Issued in the Official European Union Journal dated 24 th Aug 12  GB has to be compliant by 1 st October 2013 (July 2016 for Firm Day Ahead UIOLI)  Compliance / Impact Assessment continues to be discussed with Ofgem  In principle National Grid CMP arrangements already broadly compliant  But continue to focus on areas where clarification required  Ofgem is also discussing compliance with other GB Interconnector Operators.  Further information please contact matthew.hatch@nationalgrid.commatthew.hatch@nationalgrid.com

9. Overview of consultation responses

10. BAL NC Refinement Workshop 26 July 2012  Event well attended - 83 stakeholders  ACER presented initial reaction to Draft Code  ENTSOG reported briefly on:  51 responses to the public consultation; and  Processes to identify key stakeholder issues contained within the replies to the 57 consultation questions  The stakeholder issues, rather than the questions were addressed:  Preliminary views provided on key issues at workshop  Further details to be provided in the “Analysis of Decision” (AoD) supporting document 10

11. NG View on refined Draft Code  NG initial impact assessment on Draft Code presented May 2012 to TX Workgroup. Draft Code is:  Generally consistent with ACER’s Framework Guidelines  Broadly consistent with the GB regime  However, there are some conflicts with the UNC:  Majority were initiated via the ACER framework Guidelines  Nominations at Interconnection Points  No further impacts identified as a result of the code refinements but NG have reservations about how one key issue has been addressed 11

12. Rejection of nomination due to a physical constraint  22 Respondents raised issues  Including BP Gas Marketing, Centrica and Energy UK  Rejection criteria related to when a physical constraint occurs is not precise enough  The TSO should not be able to reject nominations because of a physical constraint unless an emergency or Force Majeure are in place  Rationale for arguments:  T his clause will undermine the concept of firm capacity  TSO can manage problems in balancing the system using market products or using balancing services  TSOs can offer interruptible capacity - it’s a capacity issue  Workshop 26 July – E.ON raised concerns again

13. ENTSOG revised proposal*  Amendments are proposed to allow a rejection or amendment of a nomination under two main circumstances:  the gas quantity to be transported is likely to endanger the system integrity of the transmission network; or  the TSO has already taken actions for that Gas Day to manage the availability of capacity at that Interconnection Point including but not limited to:  curtailment of interruptible capacity rights;  capacity buy-back in accordance with the Regulation;  any other arrangement defined under the national rules.  The use of this rule is supported by a provision that the TSO must maintain a record of these circumstances and agree a rule to report them to their NRA *Note: at time of the development of these slides

14. AoD Justification*  Capacity management rules are not part of the network code  “It has become apparent to ENTSOG in the development of the code that there is no capacity management rule set for dealing with issues in regard to a network user’s inability to use capacity rights.  These issues while clearly important are nevertheless outside of the scope of the balancing network code and may need to be addressed in a subsequent code” *Note: at time of the development of these slides

15. NG Reservations  Given the Nominations at IPs strong link to flows, this proposal raises issues with the GB constraint management process, where such a “free option” [to reduce gas flows] is not currently included  NG have raised concerns about the potential conflict with Reg 715/CAM introduced by the ENTSOG proposal  ‘…firm capacity means gas transmission capacity contractually guaranteed as uninterruptible…’  ‘interruptible capacity’ means gas transmission capacity that may be interrupted by the transmission system operator ….’  Reasons for interruption are specified in CAM 15

16. Stakeholder Support Process  14 th September to 28 September  ENTSOG will publish:  Refined Draft code  AoD  This is not a formal consultation  Stakeholders will be able to indicate support (yes or no) by chapter and the code overall

17. Next Steps  Stakeholder support process - 14 th Sept to 28 Sept  Another iteration of the code will be submitted for ENTSOG Board approval in October  ENTSOG will submit the final Draft Code and AoD document to ACER on 5 November 2012  Commission will complete the impact assessment and have encouraged ACER, ENTSOG and individual stakeholders to contribute data to inform the Commission’s IA  With this in mind a questionnaire has been issued to TSOs and NRAs – to be completed by 28 September 17

19. 19 Current Position  ACER published Draft Framework Guidelines on 16 th March 2012  Responses were submitted by 16 th May 2012  ACER published final Framework Guidelines and its Evaluation of Responses on 26 th July 2012  This presentation summarises:  the main changes to the FGs  ENTSOG’s indicative timetable for this Code

20. 20 Topic Areas  Interconnection Agreements  Harmonisation of Units  Gas Quality  Odourisation  Data Exchange  Capacity Calculation

21. Draft v Final Framework Guideline  Largely ‘tweaks’ rather than fundamental change  Implementation period has been reduced from 18 months post comitology to 12  New section on dispute resolution  Removal of requirement to develop a ‘standard’ Interconnection Agreement  Potential for use of common units to be extended to other measurements in addition to energy, volume pressure and CV  Suppliers to be considered in addition to shippers and end- consumers to receive gas quality information  Text on odourisation has been softened  Removal of ‘Cross-border Cooperation’ section
