Analysis

(a)

identify the relevant risk factors for the Member State, including their likelihood and impact;

(b)

describe the criteria used to determine whether a system is exposed to high/unacceptable risks;

(c)

set a list of relevant risk scenarios in accordance with the risk factors and their likelihood and describe how the selection was made.

4. Risk analysis and assessment

Analyse the set of relevant risk scenarios identified under point 3. In the simulation of risk scenarios include the existing security of gas supply measures, such as the infrastructure standard calculated using the N – 1 formula as set out in point 2 of Annex II, and the gas supply standard. Per risk scenario:
