The gas industry has to be able to match the supply of natural gas to the demand. Storage facilities are indispensable.
Traditionally, gas was stored during the summer period and the entire volume was withdrawn in winter for both peak
demand and as a partial substitute for long-haul pipeline capacity. But times are changing, also for gas storage.
