Division 3.2 ...F1

N – 1 formula

1. (i)

   the identification of the single largest gas infrastructure;

2. (ii)

   the calculation of the N – 1 formula F2...;

3. (iii)

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

4. (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);

5. (v)

   if so decided by the F3Secretary of State, calculation of the N – 1 formula using demand-side measures:

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

   • a 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 3(a)(iii) of this Annex),

   • 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),

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

6. (vi)

   F4...

bi-directional capacity

1. (i)

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

2. (ii)

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

3. (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.
