  • 21 underground gas storage sites in Europe
  • 12.2 Gm3 of gas storage capacity


  1. Balancing supply and demand
    Natural gas consumption varies significantly according to seasons, days and time of day. Underground gas storage provides reliable and continuous gas supply all year long. For example, it makes a vital contribution to covering peaks of consumption in winter or at certain times of day.
  2. Securing supply
    Located close to consumption sites, underground gas storage facilities provide a local and short-term source of physically available gas. As a result they guarantee security of supply and avoid load shedding and the waiting time caused by the transport of natural gas by pipeline or LNG tanker. 
    Gas storage provides a response to exceptional demand or temporary disruption of a source of supply (due to technical, economic or political factors, for example). Thus, storage can help reduce the economic and social impact of a supply outage.
  3. Greater flexibility
    The opening and growth of the natural gas market have significantly changed the needs of the players involved. By providing a rapid response to peaks in demand, storage has become vital to ensuring flexibility, offering market operators a responsive sourcing option. 
  4. Optimising gas infrastructure
    Storage facilities, key links in the gas supply chain in various locations across the country, help to optimise gas infrastructure and ensure a more efficient use of transport systems.
