GDF SUEZ establishes two new subsidiaries dedicated to methane tankers and underground storage: Elengy and Storengy

Following the shareholders' vote at GDF SUEZ's General Meeting on 17 December 2008, subsidiaries Elengy, dedicated to methane tanker activities, and Storengy, dedicated to underground natural gas storage, were established on 31 December 2008.

Elengy encompasses all three of the Group's methane tankers in France (Fos Tonkin, Montoir-de-Bretagne and Fos-Cavaou). With over 400 employees, Elengy is responsible for all development, operation and maintenance activities on the methane tankers, as well as for marketing the goods and services directly or indirectly related with the facilities. Elengy also makes its LNG expertise available to the rest of the Group to develop international projects.

Thierry Trouvé, former Vice Managing Director of GRTgaz, was appointed Managing Director of Elengy, upon the vote.

Storengy is home to all of the Group's natural gas storage activities in France. Employing over 900 men and women, Storengy is in charge of all planning, development, operation and maintenance of natural gas storage infrastructures, as well as for marketing the goods and services directly or indirectly related to the facilities.

Jean-Marc Leroy, former Director of Storage Activities at GDF SUEZ, will take over as Managing Director of Storengy.

Both of the subsidiaries will be established as limited companies, fully-owned by GDF SUEZ. Elengy and Storengy will be consolidated on a global integration basis. Their creation has no impact on the Group's consolidated accounts.

Elengy and Storengy each have their own visual identity:

GDF SUEZ Group is currently the world leader in LNG and the 2nd-ranking underground natural gas storage provider in Europe.
