EWE-H-GAS-ZONE

In the course of the L-H-gas market area/storage conversion, the UGS EWE L-gas caverns will be successively converted to H-gas caverns (EWE-H-GAS-ZONE) in the coming years.
Not only due to technical reasons, the technically available storage capacities may change from time to time. In particular, due to the market area conversion starting in summer 2021 and the corresponding successive storage conversion from L- to H-gas, certain data inconsistencies may occur for technical/operational reasons.
