3. 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 neighbouring Member States, demand-side measures) and the existing bidirectional capacities, as follows: the identification of the single largest gas infrastructure of common interest for the region; the calculation of the N – 1 formula at regional level; a description of the values used for all elements in the N – 1 formula, including intermediate figures used for the calculation (e.g. for EP_(m) indicate the capacity of all entry points considered under this parameter); an indication of 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). N – 1 formula the identification of the single largest gas infrastructure; the calculation of the N – 1 formula at national level; 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); 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); if so decided by the Member 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)); if so agreed with the competent authorities of the relevant risk group(s) or with the directly connected Member States, joint calculation(s) of the N – 1 formula: the calculation of the N – 1 formula in accordance with point 5 of Annex II, a description of the values used for all elements in the N – 1 formula, including intermediate values used for the calculation (if different to the figures described under point 3(a)(iii) of this Annex), an indication of 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), an explanation of the agreed arrangements to ensure compliance with the N – 1 formula; bi-directional capacity indicate the interconnection points equipped with bidirectional capacity and the maximal capacity of bi-directional flows; indicate the arrangements governing the use of the reverse flow capacity (e.g. interruptible capacity); 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.
