GSE storage levels in Europe Update on AGSI

GSE storage levels in Europe • • • Update on AGSI Recent & Historical Storage Development Overview Winter 2009/2010 Storage Characteristics & different roles Complexity GCG – 15 th Dec. 2010, Brussels Siegfried KISS 1

GSE storage levels in Europe – Update on AGSI • Data quality management has been enhanced • Historical Data available starting 2007 and up to date • Graphs showing storage level development and trends are on the way • Adopted Aggregation and further Contributors • AGSI on its way to become a well known Tool (eg. : SOS-Monitoring) 2

GSE storage levels in Europe – The role of Storage Balancing seasonal variations in consumption Security of supply Covering demand peaks Eg. : balancing renewables The role of storage Enhancing effectiveness of gas transport Increasingly for arbitrage / Trading opportunities Different roles of storage request different injection and withdrawal rates and volumes !!! 10

GSE storage levels in Europe – Complexity • Each storage is unique • Different roles of storage request different injection and withdrawal rates and volumes • SSO´s and clients have to live with technical & geological constraints • Coherence between volume and rates needs to be taken into account (UIOLI, Bundle) SSO´s are always ready to develop and improve storage-products for the market needs 11

GCG - 13 th January 2011 Next GSE-Presentation • Gas Storage: „what does it mean? “ • Characteristics of gas storages in detail • How to manage this complexity for a secure and flexible gas supply 12
