Gas, in these cases, is stored underground taking advantage of old deposits, or it is injected in deep water stratum or in cavities generated in salt formations. Enagás manages three underground stores: Serrablo, located in Huesca, Gaviota, located in Bizkaia coast and Yela, located in Guadalajara. Maximum pressure at the underground storage facilities entrance is between 72 and 80 bars, depending on the design pressure of the pipeline to which they are connected. Minimum pressure is 45 bar for all of them. For further information about these underground storages, please consult Serrablo, Gaviota and Yela corporate brochures at the bottom.
