ENTSOG Gas Regional Investment Plan South 2017 - Main Report

7.2.2 N-1 INFRASTRUCTURE ASSESSMENT (FROM TYNDP 2017 ESW-CBA)

ENTSOG includes the N-1 indicator in the TYNDP assessment: this indicator derives from Regulation (EC) 994/2010. It aims at identifying which countries are not able to satisfy/meet its peak demand (1 in 20) without the larger infrastructure of the country. N-1 (ESW-CBA) indicator shows security of supply needs for countries with values below 100%. Portugal is the only country in the South Region not fulfilling for all scenarios the N-1 requirements. The PCI 3 rd Interconnection point PT-ES would mitigate the results for N-1 indicator in Portugal for all demand scenarios as it can be seen in the figure below from 2025 for Green Revolution scenario.
