Jemgum storage facility
The main advantage of cavern storage: The cavities in the rock salt make it possible to inject or withdraw the entire storage volume within a very short space of time.
Up to 1 million m³ of natural gas can be extracted from the Jemgum storage facility in just one hour. This technical advantage allows for the most efficient and flexible use of salt caverns together with renewable energy sources.
A highly flexible cavern storage
Since 2008, one of the biggest cavern gas storages in Germany had been being built in the municipality of Jemgum in Lower Saxony, and celebrated commissioning in 2013.
WINGAS planned and coordinated the construction works of this state-of-the-art gas storage facility in alignment with VNG Gasspeicher. The storage has a working gas volume of about 900million cubic metres of natural gas. The storage is operated jointly by astora and VNG Gasspeicher. Five sixths of the total storage capacities are commercialised by astora.
The storage facility is connected to the GASCADE Gastransport GmbH pipeline network, which is part of the THE market area cooperation, as well as to the market area of Gasunie Transport Services B.V. (GTS), market area TTF (title transfer facility) in the Netherlands. This enables customers to tailor the Jemgum storage products to meet their needs in two market areas – flexibly and across borders.
Since the surrounding Rheiderland is an important conservation area, we began working intensively in line with statutory requirements on concepts to ensure environmental compatibility even before the first sod was turned. For example, construction work for connecting the storage facility to the gas transportation network took place outside the bird breeding seasons, and we selected lighting for our operation site that is adapted to the natural surroundings. Additional noise protection ensures that local residents and animals are not disturbed by the operation.
Last but not least, the region also benefits from new jobs and the commissioning of local companies to build and operate the facility.
