This part of the assessment analyses the nature of the gas made available. It is carried out throughout the year including summer, winter and peak days. The aim is to identify supply sources having a predominant role in the demand-sup- ply balance for each country. This dependence is measured through the following indicators: \\ From a physical perspective through the Cooperative and Uncooperative Supply Source Dependence \\ From a price perspective through the Supply Source Price Dependence This part of the assessment also measures the ability of each country to benefit from a reduction of the price of one or several import sources through the Supply Source Price Diversification indicator. The existence of a global LNG market with one reference price leads to the consid- eration of LNG as a single source once it has entered the European gas system. From a security of supply perspective it is also important to acknowledge the embedded diversification of LNG supply. For this reason ENTSOG has not identified any LNG disruption event that could have a European impact. Therefore no LNG disruption was considered. In addition, the report identified in particular the ability of countries to benefit from further diversification through LNG due to its embedded diversification.
