IN FRANCE
In addition to the development of its existing sites in France, a new site will enter into service in a few years in Hauterives, in the region of Rhône-Alpes (affiliated to the storage site of Tersanne).
Geographic location
The underground storage will be located in Hauterives in the northern part of the Department of Drôme, at about 20 km from Romans-sur-Isère.
Project objectives
The geological characteristics of the Hauterives site are analogous to those of the Tersanne site, which is located about 7 kilometres away. They are favourable to the creation of a Salt cavern storage.
GDF SUEZ is associated with Perstorp through an industrial partnership agreement about the creation of Salt caverns for natural gas storage. Thus Chloralp, a subsidiary of Perstorp, injects water and removes the brine (mix of water and salt obtained when leaching the caverns) via its facilities at the Saline de Hauterives. Later, Perstorp transforms the brine into different products in Pont-de-Claix (Department of Isère), enabling its Customers to produce foams, paint and industrial coating.
The first phase includes the creation of two caverns. The construction works should be completed in 2012. Later, up to 5 caverns could be developed.
The volume of natural gas stored in one of these caverns will correspond to about 80% of the annual consumption of the city of Valence.
Project characteristics
The project includes:
- the creation of salt caverns,
- the construction of surface facilities (connection to the natural gas transport network, metering station, regulation, dehydration of withdrawn gas, ...).
In order to limit the land use of the facilities to be installed in Hauterives, the compression equipment required for the injection of natural gas into the caverns will be located at the Tersanne gas plant.

Abroad
In order to meet the new requirements of the gas market, Storengy has undertaken an ambitious storage site development programme in Europe and abroad.
Today Storengy, through its subsidiaries and participations, operates or develops underground natural gas Storage Facilities in Germany, the United Kingdom and Canada.
In Germany
Storengy Deutschland currently develops the storage capacities of the salt cavern storage of Peckensen (Saxony-Anhalt), which is in operation since 2002. The first expansion phase of the Peckensen salt cavern storage was completed with the commissioning of caverns 2 and 3 in 2010. The second expansion phase has already begun with the leaching operations of caverns 4 and 5.
These new caverns will enter into service in 2013/14. Their working gas volume will amount to about 160 Mcm. The capacities have already been marketed over the long term.
On August 31st 2011, Storengy concluded the purchasing agreement of 5 natural gas underground storage facilities in Germany as well as a 19.7% stake in an additional one. The transaction that was first announced 31 January 2011 comprises the storage facilities held by BEB Speicher GmbH and by ExxonMobil Gasspeicher Deutschland GmbH. This transaction includes underground gas storages in
- Uelsen (next to the Dutch border)
- Harsefeld (between the cities of Hamburg and Bremen)
- Lesum (next to Bremen)
- Reitbrook (next to Hamburg)
- Schmidhausen (next to Munich)
- as well as 19.7% stake in Breitbrunn-Eggstädt (next to Munich)
These facilities include 4 Depleted fields ans 2 salt caverns with a total working gas volume of about 1.5 Gcm.
Together with the storage facilities of Peckensen and Fronhofen which had previously been part of the portfolio of Storengy Deutschland GmbH, the company currently operates 7 storage facilities within Germany as well as a 19.7% stake in an additional one.
In the course of this transaction, Storengy re-arranged its business model in Germany.
Storengy is the first provider to offer asset management as well as the technical operatorship of its storage facilities – the latter one being run by the newly established Storengy Deutschland Betrieb company, headquartered in Hanover.
Furthermore, Gasag, another subsidiary of the GDF SUEZ Group, operates the Grunewald Aquifer storage in Berlin.
