Construction

Ground was broken at the site of UGS Katharina in Peissen, near Bernburg, Saxony-Anhalt; in 2011. Named after Russian empress Catherine the Great, the facility is to be expanded stage-by-stage until its completion in 2025.

Upon its completion, UGS Katharina’s 12 caverns will have a working gas capacity of more than 600 million cubic metres – enough to supply over 300,000 households with natural gas for a full year. As in the case of the nearby UGS Bernburg, UGS Katharina’s caverns are being constructed by drilling and leaching underground mineral salt deposits down to a depth of 500 to 700 metres.
