7.2.4 SUPPLY SOURCE DEPENDENCE

The supply source dependence is the minimum share of a given source that a country needs in order to cover its demand, and that cannot be covered by another supply source. The indicator from ENTSOG CBA methodology showing the depend- ence to a given supply source is the Cooperative Supply Source Dependence (CSSD). In this indicator, the dependence to each supply source is analysed independently, assuming cooperation between member States in order to share the level of dependence to a given supply source.
