4. 3-4 November 2005GIE Annual Conference 2005, Athens4 2. Why storage? Balancing seasonal variations in consumption Securing gas supply in case of interferences in production, transport or supply Covering demand peaks Enhancing cost effectiveness of gas transport Traditional roles of storages as important guarantor of security of supply

10. 3-4 November 2005GIE Annual Conference 2005, Athens10 Future role for storage  Seasonal modulation and security of supply (technical availability) seconded by products to support the new market  Storage is and will be part of the flexibility market  Security of Supply remains the most important target

11. 3-4 November 2005GIE Annual Conference 2005, Athens11 Overview of flexibility instruments

12. 3-4 November 2005GIE Annual Conference 2005, Athens12 4. Preconditions to develop storage  Clear allocation of responsibilities of different market players  Clear, stable and incentivising investment climate for infrastructure development  Long term commitments between operators and suppliers  (Self)-regulation should foster entrepreneurship: stability, predictability, simplicity

13. 3-4 November 2005GIE Annual Conference 2005, Athens13 Increasing demand for storage in order to: -Balance declining production swing (e.g. need for strategic storage in UK) -Meet growing demand of natural gas (e.g. in East and Southern Europe) -Make use of market flexibilities (e.g. price arbitrage) -Overcome delivery bottlenecks through long distance transports (e.g. producers entry to European market like Gazprom)  Need for allowing storage activities to be in line with market expectations  Need for regulative stability and positive investment signals Conclusions

14. 3-4 November 2005GIE Annual Conference 2005, Athens14 Epilogue: Outcome Madrid X  Progress of Storage System Operators recognized  Overall compliance in the field of transparency and secondary market edentified as “construction sites”: -Publication of Operational Datas vs. Confidentiality Requirements -Bulletin boards not yet established with all SSOs -Limited secondary trade of unbundled services – solutions in sight  GSE Workshop on this issues : Nov. 16.
