6.1.4 Keyconclusions

Key conclusions obtained in theResilience Assessment for the SouthRegion are: \\ According to theTYNDP, thegas system in theSouthRegionwill have sufficient capacity to achieve a full supply-demand balancewith the FIDprojects. \\ No impact in theSouthRegionhasbeendetected in the supplydisruptions an- alysed in the TYNDP, due to the flexibility in the network to rerouting supply of the interrupted sources through alternative routes, and by additional gas from UGS and LNG Terminals. \\ UGS and LNG Terminals play a significant role in the South Region providing short term flexibility and security of demand. The LNG stored in the LNG tanks enables the increment of Send-Out from LNG Terminals, as well as the with- drawal from the UGS when adequate Working Gas Volume is available, responding to highdemand events. \\ The lack of resilience to low LNG deliverability detected for the Iberian Peninsula is not de facto a risk of security of supply for Spain due to the high level of LNGdiversification by country origin. \\ The lack of resilience to low LNG deliverability in Portugal could be improved promoting the LNG diversification.

6.2 SupplySourceDependence

Supply Source Dependence assessment aims at the identification of Zones whose balance depends strongly on a single supply source. This analysis has beendoneunder averagedemand conditions to capture the year- ly character of the analysis.

DEMAND

SUPPLY

“Full Minimisation” of source S – – Source S is reduced down to theminimum required to balance all zone – – Rest of the sources increase up to each technical capacity

1-day Average Situation

Supply Source Dependence to source S is identifiedwhen a Zone requires at least a 20% supply share of the supply source S
