The competent authority shall identify the natural gas undertakings referred to in the first subparagraph of this paragraph and specify them in the preventive action plan. Any new measures envisaged to ensure the supply standard shall comply with the procedure established in Article 8(4) to (5). Member States may comply with the obligation laid down in the subparagraph through the implementation of energy efficiency measures or by replacing the gas with a different source of energy, inter alia renewable energy sources, to the extent that the same level of protection is achieved. 2. Any increased supply standard going beyond the 30-day period referred to in points (b) and (c) of paragraph 1 or any additional obligation imposed for reasons of security of gas supply shall be based on the risk assessment▐, shall be reflected in the preventive action plan and shall: (a) comply with Article 3(6); (b) not impact negatively on the ability of any other Member State to supply its protected customers in accordance with this Article in the event of a national, regional or Union emergency; and
(b) taking into account the maximal interconnection capacity of each border entry and exit point and various filling levels for storage. 2. The competent authorities within each ▌ risk shall agree on a cooperation mechanism to conduct the common risk assessment within the deadline provided for in paragraph ▌ 5 of this Article. Competent authorities shall report to the GCG on the agreed cooperation mechanism for conducting the common risk assessment ▌ 11 months before the deadline for the adoption of the common risk assessment and ▌ its updates ▐. At the request of a competent authority the Commission may have a facilitating role overall in the preparation of the common risk assessment, in particular for the establishment of the cooperation mechanism. If competent authorities within a ▌ risk group do not agree on a cooperation mechanism, the Commission ▌ shall ▌ propose a cooperation mechanism for that ▌ risk group, after consulting with the competent authorities concerned. The Member States concerned shall agree on a cooperation mechanism for that ▌ risk group taking utmost account of the Commission's proposal. Within the agreed cooperation mechanism each competent authority shall share and update 10 months before the deadline for the notification of the common risk assessment or its updates all ▐ national data necessary for the preparation of the common risk assessment, in particular for running the various scenarios referred to in point (c) of paragraph ▐ 1b. 3. The risk assessments referred to in paragraphs 1 and 1a be prepared in accordance with the relevant template in Annex IV. If necessary Member States may add additional information. The Commission shall be empowered to adopt delegated acts in accordance with Article 18 to amend those templates, after consulting the GCG, in order to reflect the experience gained in the application of this Regulation, while reducing the administrative burden on Member States. 4. Natural gas undertakings, industrial gas customers, the relevant organisations representing the interests of household and industrial gas customers as well as Member States and the national regulatory authority, where it is not the competent authority, shall cooperate with the competent authorities and provide it upon request
information provided by natural gas undertakings under this paragraph, provided that the same information has not been transmitted already to the Commission. 5. the Commission considers that the gas supply in ▌ part of or in the Union as whole is ▌at risk or is likely to be ▌at risk that may lead to the declaration of one of the crisis levels mentioned in Article 10(1), it may require the competent authorities concerned to collect and submit to the Commission information necessary to assess the situation of the gas supply █. The Commission ▌ shall share its assessment with the GCG. 6. In order for the Competent Authorities and the Commission to assess the situation of the security of supply at national, regional and Union level, each natural gas undertaking shall notify: (a) to the competent authority concerned the following details of gas supply contracts with a dimension and a duration of more than one year which they have concluded to procure gas: (i) contract duration; (ii) yearly contract volumes; (iii) contracted maximum daily volumes in the event of an alert or emergency; (iv) contracted delivery points; (v) minimum and monthly ▐ gas volumes; (vi) conditions for the suspension of gas deliveries. (vii) an indication whether the contract individually or cumulatively with its contracts with the same supplier or its affiliates is equivalent to or exceeds the threshold of 28% as referred to in point (b) of Article 13(6)in the most affected Member State. (b) to the competent authority of the most affected Member State▐ immediately after their conclusion or modification ▐ its gas supply contracts with a duration of more than one year, concluded or modified after … [OJ: Please insert the date of entry into force of this Regulation] that individually or cumulatively
The technical capacity of all remaining available gas infrastructure in the event of disruption of the single largest gas infrastructure shall be at least equal to the sum of the total daily gas demand of the calculated area during a day of exceptionally high gas demand occurring with a statistical probability of once in 20 years. The results of the N – 1 formula, as calculated below, shall be at least equal to 100 %. Calculation method of the N-1 formula , N – 1 ≥ 100 % The parameters used for the calculation shall be clearly described and justified. For the calculation of the EPm, a detailed list of the entry points and their individual capacity shall be provided. Definitions of the parameters of the N-1 formula ‘Calculated area’ means a geographical area for which the N – 1 formula is calculated, as determined by the competent authority. Demand-side definition ‘Dmax’ means the total daily gas demand (in mcm/d) of the calculated area during a day of exceptionally high gas demand occurring with a statistical probability of once in 20 years. Supply-side definitions ‘EPm’: technical capacity of entry points (in mcm/d), other than production, LNG and storage facilities covered by Pm, LNGm and Sm, means the sum of the technical capacity of all border entry points capable of supplying gas to the calculated area. ‘Pm’: maximal technical production capability (in mcm/d) means the sum of the maximal technical daily production capability of all gas production facilities which can be delivered to the entry points in the calculated area. ‘Sm’: maximal technical storage deliverability (in mcm/d) means the sum of the maximal technical daily withdrawal capacity of all storage facilities which can be delivered to the entry points of the calculated area, taking into account their respective physical characteristics.
