Regulation (EU) 2017/1938 of the European Parliament and of the Council of 25 October 2017 concerning measures to safeguard the security of gas supply and repealing Regulation (EU) No 994/2010 (Text with EEA relevance) (c. 1938)

ANNEX V Template for the national risk assessment

2. Infrastructure standard (Article 5)

Describe how the infrastructure standard is complied with, including the main values used for the N – 1 formula and alternative options for its compliance (with directly connected Member States, demand-side measures) and the existing bidirectional capacities, as follows:

(a)

N – 1 formula

(i)

the identification of the single largest gas infrastructure;

(ii)

the calculation of the N – 1 formula at national level;

(iii)

a description of the values used for all elements in the N – 1 formula, including intermediate values used for their calculation (e.g. for EP_m indicate the capacity of all entry points considered under this parameter);

(iv)

an indication of the methodologies used, if any, for the calculation of parameters in the N – 1 formula (e.g. D_max) (use annexes for detailed explanations);

(v)

an explanation of the results of the calculation of the N – 1 formula considering the level of storages at 30 % and 100 % of the maximum working volume;

(vi)

an explanation of the main results of the simulation of the N – 1 formula using a hydraulic model;

(vii)

if so decided by the Member State, a calculation of the N – 1 formula using demand-side measures:

• calculation of the N – 1 formula in accordance with point 2 of Annex II,

• description of the values used for all elements in the N – 1 formula, including intermediate figures used for the calculation (if different to the figures described under point 2(a)(iii)),

• indicate the methodologies used, if any, for the calculation of parameters in the N – 1 formula (e.g. D_max) (use annexes for detailed explanations),

• explain the market-based demand-side measures adopted/to be adopted to compensate a disruption of gas supply and its expected impact (D_eff);

(viii)

if so agreed with the competent authorities of the relevant risk group(s) or with directly connected Member States, joint calculation(s) of the N – 1 formula:

• calculation of the N – 1 formula in accordance with point 5 of Annex II,

• description of the values used for all elements in the N – 1 formula, including intermediate values used for their calculation (if different to the figures described under point 2(a)(iii)),

• indicate the methodologies and assumptions used, if any, for the calculation of parameters in the N – 1 formula (e.g. D_max) (use annexes for detailed explanations),

• explain the agreed arrangements to ensure compliance with the N – 1 formula;

(b)

bi-directional capacity

(i)

indicate the interconnection points equipped with bidirectional capacity and the maximal capacity of bi-directional flows;

(ii)

indicate the arrangements governing the use of the reverse flow capacity (e.g. interruptible capacity);

(iii)

indicate interconnection points where an exemption has been granted in accordance with Article 5(4), the duration of the exemption and the grounds on which it was granted.
