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)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Legislation.gov.uk publishes the UK version. EUR-Lex publishes the EU version. The EU Exit Web Archive holds a snapshot of EUR-Lex’s version from IP completion day (31 December 2020 11.00 p.m.).
This is the original version as it was originally adopted in the EU.
This legislation may since have been updated - see the latest available (revised) version
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:
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 their calculation (e.g. for EPm 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. Dmax) (use annexes for detailed explanations);
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;
an explanation of the main results of the simulation of the N – 1 formula using a hydraulic model;
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. Dmax) (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 (Deff);
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. Dmax) (use annexes for detailed explanations),
explain 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.
