About 60 per cent of the working gas is stored in storage reservoirs and some 40 per cent in storage caverns. At the end of 2010, there were more than 25 storage operators offering some 21 billion cubic metres (bcm) of working gas. For a number of years, underground gas storage in Germany has been showing a strong upward trend with existing facilities – especially caverns – being expanded and new facilities being built (Source: ERDÖL ERDGAS KOHLE 127, Vol. 2011, issue 11).

E.ON Gas Storage operates 16 underground gas storage facilities

E.ON Gas Storage has some 8.5 bcm of working gas capacity in 16 underground storage facilities at 14 locations in Germany and Austria. For Europe as a whole (i.e. including its subsidiaries in Hungary and the UK) the figure is over 12.5 bcm. E.ON Gas Storage operates the third largest storage reservoir in Germany, Bierwang, which is a former gas deposit located in sandstone strata at a depth of 1,500 metres. Its underground storage facility at Epe is by far the largest gas storage cavern in Europe. E.ON Gas Storage stores about 2.1 bcm of working gas in Epe.
