ENTSOG Gas Regional Investment Plan South 2017 - Main Report
A similar behavior is observed in the Portuguese gas system: the level of LNG regasification noticeably increases with variations of VIP Iberico. An example of this can be seen in figure 7.3 below, where a significant increase of LNG regasification levels occurred during the month of October and December of 2016, enhanced by the decrease of VIP Iberico during the same period. Carriço underground storage in Portugal helps with daily modulation especially on higher demand days.

In France, there is higher modulation of the demand over the year linked to the heating for residential consumers (seasonal effect). From a general point of view, the regasification and pipeline entries are mainly stables over the time, and the variability of the demand is assured by the UGS which fully play their role. As shown in the graph, the higher period of demand in the beginning of 2017 as been managed through a higher solicitation of the UGS, the LNG stocks in the terminals being at a low level at that time.
