Underground Storage Facilities
In order to adjust offer to demand and face consumption peaks brought on by seasonal variations, interruptions in supply, etc., it is necessary to store large quantities of gas.
The Serrablo gas field is located between the towns of Jaca and Sabiñánigo (Huesca). Gaviota is an “off-shore” gas field and is located near Bermeo (Vizcaya). The last one, Yela, located in Brihuega (Guadalajara), was put into operation in the last Quarter of 2012.
Maximum pressure at underground storage facilities varies 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.
