7.2 Assessment of the Gas

System in the South Region

UGS and LNG terminals use: the main role of these facilities

Analysing the behavior of LNG regasification terminals, IPs and UGS’s in the South Region, the different way of covering gas demand in the three countries can be observed. The Iberian Peninsula relies primarily on LNG and Algerian gas, due to its proximity to Algeria and higher LNG import capacity. France, being well intercon- nected, has broader access to different supply sources and higher UGS withdrawal/ injection capacity. Focusing on the Spanish gas system, LNG stock varies according to the level of regasification and LNG cargos arriving to Spanish LNG terminals. In addition, fluctuations in the IPs are covered with a higher LNG regasification. Variations of Algerian pipeline imports have impact on the level of LNG regasification and IPs with European countries, due to its higher capacity. Seasonal modulation of underground storages plays a secondary role in the Spanish gas system resulting from its lower capacity compared to LNG terminals or IPs and strategic stocks.
