Haidach gas storage facility – ten years of supply security

Straßwalchen/Kassel. With a working gas volume of over 2.6 billion cubic meters, the Haidach gas storage facility is today one of the largest in Europe. Developed over ten years from 1997 to 2007 the whole storage capacity was commissioned ten years ago, in June 2007. Constructed in two phases in a joint venture with Gazprom, WINGAS and RAG, Haidach is an example of successful international cooperation for the reason of supply security.

By using the former natural gas reservoir at Haidach as a gas storage facility, the three partner companies have chosen the most efficient, environmentally friendly and reliable way of storing energy. The reservoir rock in Haidach is unusually thick, over 100 meters thick in some areas, and extends over 17.5 square kilometers. Thanks to the high permeability of the rock, about a million cubic meters of natural gas can be injected and withdrawn from the facility per hour.

The Haidach natural gas reservoir was discovered in 1997 as a pore reservoir at a depth of over 1,600 meters by RAG and was one of Austria’s largest discoveries, with a volume of 4.3 billion cubic meters. The gas storage facility there now has a working gas volume of over 2.6 billion cubic meters.

Natural gas storage facilities are an important instrument in ensuring a secure energy supply – they are what make it possible to guarantee the stable availability of natural gas, an environmentally friendly form of energy, in the volume required. They enable us to balance out the steady gas deliveries with fluctuating gas consumption on the one hand, and seasonal and daily consumption fluctuations on the other. 

Natural gas is produced continuously the whole year in approximately the same quantities and transported over large distances. But the energy consumption of industry, power stations and households varies depending on the season and the time of day. Consumption is much higher in winter and during the day than in summer and at night time.
