Article 1Subject matter and scope1.This Regulation aims at setting non-discriminatory rules for access conditions to natural gas transmission systems taking into account the specificities of national and regional markets with a view to ensuring the proper functioning of the internal gas market.This objective shall include the setting of harmonised principles for tariffs, or the methodologies underlying their calculation, for access to the network, the establishment of third party access services and harmonised principles for capacity allocation and congestion management, the determination of transparency requirements, balancing rules and imbalance charges and facilitating capacity trading.2.Member States may establish an entity or body set up in compliance with Directive 2003/55/EC for the purpose of carrying out one or more functions typically attributed to the transmission system operator, which shall be subject to the requirements of this Regulation.

Article 2Definitions1.For the purpose of this Regulation, the following definitions shall apply:1."transmission" means the transport of natural gas through a network, which mainly contains high pressure pipelines, other than an upstream pipeline network and other than the part of high pressure pipelines primarily used in the context of local distribution of natural gas, with a view to its delivery to customers, but not including supply;2."transportation contract" means a contract which the transmission system operator has concluded with a network user with a view to carrying out transmission;3."capacity" means the maximum flow, expressed in normal cubic meters per time unit or in energy unit per time unit, to which the network user is entitled in accordance with the provisions of the transportation contract;4."unused capacity" means firm capacity which a network user has acquired under a transportation contract but which that user has not nominated by the deadline specified in the contract;5."congestion management" means management of the capacity portfolio of the transmission system operator with a view to optimal and maximum use of the technical capacity and the timely detection of future congestion and saturation points;6."secondary market" means the market of the capacity traded otherwise than on the primary market;7."nomination" means the prior reporting by the network user to the transmission system operator of the actual flow that he wishes to inject into or withdraw from the system;8."re-nomination" means the subsequent reporting of a corrected nomination;9."system integrity" means any situation in respect of a transmission network including necessary transmission facilities in which the pressure and the quality of the natural gas remain within the minimum and maximum limits laid down by the transmission system operator, so that the transmission of natural gas is guaranteed from a technical standpoint;10."balancing period" means the period within which the offtake of an amount of natural gas, expressed in units of energy, must be offset by every network user by means of the injection of the same amount of natural gas into the transmission network in accordance with the transportation contract or the network code;11."network user" means a customer or a potential customer of a transmission system operator, and transmission system operators themselves in so far as it is necessary for them to carry out their functions in relation to transmission;12."interruptible services" means services offered by the transmission system operator in relation to interruptible capacity;13."interruptible capacity" means gas transmission capacity that can be interrupted by the transmission system operator according to the conditions stipulated in the transportation contract;14."long-term services" means services offered by the transmission system operator with a duration of one year or more;15."short-term services" means services offered by the transmission system operator with a duration of less than one year;16."firm capacity" means gas transmission capacity contractually guaranteed as uninterruptible by the transmission system operator;17."firm services" means services offered by the transmission system operator in relation to firm capacity;18."technical capacity" means the maximum firm capacity that the transmission system operator can offer to the network users, taking account of system integrity and the operational requirements of the transmission network;19."contracted capacity" means capacity that the transmission system operator has allocated to a network user by means of a transportation contract;20."available capacity" means the part of the technical capacity that is not allocated and is still available to the system at that moment;21."contractual congestion" means a situation where the level of firm capacity demand exceeds the technical capacity;22."primary market" means the market of the capacity traded directly by the transmission system operator;23."physical congestion" means a situation where the level of demand for actual deliveries exceeds the technical capacity at some point in time.2.The definitions contained in Article 2 of Directive 2003/55/EC, which are relevant for the application of this Regulation, shall also apply with the exception of the definition of transmission in point 3 of that Article.

Article 3Tariffs for access to networks1.Tariffs, or the methodologies used to calculate them, applied by transmission system operators and approved by the regulatory authorities pursuant to Article 25(2) of Directive 2003/55/EC, as well as tariffs published pursuant to Article 18(1) of that Directive, shall be transparent, take into account the need for system integrity and its improvement and reflect actual costs incurred, insofar as such costs correspond to those of an efficient and structurally comparable network operator and are transparent, whilst including appropriate return on investments, and where appropriate taking account of the benchmarking of tariffs by the regulatory authorities. Tariffs, or the methodologies used to calculate them, shall be applied in a non-discriminatory manner.Member States may decide that tariffs may also be determined through market-based arrangements, such as auctions, provided that such arrangements and the revenues arising therefrom are approved by the regulatory authority.Tariffs, or the methodologies used to calculate them, shall facilitate efficient gas trade and competition, while at the same time avoiding cross-subsidies between network users and providing incentives for investment and maintaining or creating interoperability for transmission networks.2.Tariffs for network access shall not restrict market liquidity nor distort trade across borders of different transmission systems. Where differences in tariff structures or balancing mechanisms would hamper trade across transmission systems, and notwithstanding Article 25(2) of Directive 2003/55/EC, transmission system operators shall, in close cooperation with the relevant national authorities, actively pursue convergence of tariff structures and charging principles including in relation to balancing.

Article 4Third party access services1.Transmission system operators shall:(a)ensure that they offer services on a non-discriminatory basis to all network users. In particular, where a transmission system operator offers the same service to different customers, it shall do so under equivalent contractual terms and conditions, either using harmonised transportation contracts or a common network code approved by the competent authority in accordance with the procedure laid down in Article 25 of Directive 2003/55/EC;(b)provide both firm and interruptible third party access services. The price of interruptible capacity shall reflect the probability of interruption;(c)offer to network users both long and short-term services.2.Transportation contracts signed with non-standard start dates or with a shorter duration than a standard annual transportation contract shall not result in arbitrarily higher or lower tariffs not reflecting the market value of the service, in accordance with the principles laid down in Article 3(1).3.Where appropriate, third party access services may be granted subject to appropriate guarantees from network users with respect to the creditworthiness of such users. Such guarantees must not constitute any undue market entry barriers and must be non-discriminatory, transparent and proportionate.

Article 5Principles of capacity allocation mechanisms and congestion management procedures1.The maximum capacity at all relevant points referred to in Article 6(3) shall be made available to market participants, taking into account system integrity and efficient network operation.2.Transmission system operators shall implement and publish non-discriminatory and transparent capacity allocation mechanisms, which shall:(a)provide appropriate economic signals for efficient and maximum use of technical capacity and facilitate investment in new infrastructure;(b)be compatible with the market mechanisms including spot markets and trading hubs, while being flexible and capable of adapting to evolving market circumstances;(c)be compatible with the network access systems of the Member States.3.When transmission system operators conclude new transportation contracts or renegotiate existing transportation contracts, these contracts shall take into account the following principles:(a)in the event of contractual congestion, the transmission system operator shall offer unused capacity on the primary market at least on a day-ahead and interruptible basis;(b)network users who wish to re-sell or sublet their unused contracted capacity on the secondary market shall be entitled to do so. Member States may require notification or information of the transmission system operator by network users.4.When capacity contracted under existing transportation contracts remains unused and contractual congestion occurs, transmission system operators shall apply paragraph 3 unless this would infringe the requirements of the existing transportation contracts. Where this would infringe the existing transportation contracts, transmission system operators shall, following consultation with the competent authorities, submit a request to the network user for the use on the secondary market of unused capacity in accordance with paragraph 3.5.In the event that physical congestion exists, non-discriminatory, transparent capacity allocation mechanisms shall be applied by the transmission system operator or, as appropriate, the regulatory authorities.

Article 6Transparency requirements1.Transmission system operators shall make public detailed information regarding the services they offer and the relevant conditions applied, together with the technical information necessary for network users to gain effective network access.2.In order to ensure transparent, objective and non-discriminatory tariffs and facilitate efficient utilisation of the gas network, transmission system operators or relevant national authorities shall publish reasonably and sufficiently detailed information on tariff derivation, methodology and structure.3.For the services provided, each transmission system operator shall make public information on technical, contracted and available capacities on a numerical basis for all relevant points including entry and exit points on a regular and rolling basis and in a user-friendly standardised manner.4.The relevant points of a transmission system on which the information must be made public shall be approved by the competent authorities after consultation with network users.5.Where a transmission system operator considers that it is not entitled for confidentiality reasons to make public all the data required, it shall seek the authorisation of the competent authorities to limit publication with respect to the point or points in question.The competent authorities shall grant or refuse the authorisation on a case by case basis, taking into account in particular the need to respect legitimate commercial confidentiality and the objective of creating a competitive internal gas market. If the authorisation is granted, available capacity shall be published without indicating the numerical data that would contravene confidentiality.No such authorisation as referred to in this paragraph shall be granted where three or more network users have contracted capacity at the same point.6.Transmission system operators shall always disclose the information required by this Regulation in a meaningful, quantifiably clear and easily accessible way and on a non-discriminatory basis.

Article 7Balancing rules and imbalance charges1.Balancing rules shall be designed in a fair, non-discriminatory and transparent manner and shall be based on objective criteria. Balancing rules shall reflect genuine system needs taking into account the resources available to the transmission system operator.2.In the case of non-market based balancing systems, tolerance levels shall be designed in a way that either reflects seasonality or results in a tolerance level higher than that resulting from seasonality, and that reflects the actual technical capabilities of the transmission system. Tolerance levels shall reflect genuine system needs taking into account the resources available to the transmission system operator.3.Imbalance charges shall be cost-reflective to the extent possible, whilst providing appropriate incentives on network users to balance their input and offtake of gas. They shall avoid cross-subsidisation between network users and shall not hamper the entry of new market entrants.Any calculation methodology for imbalance charges as well as the final tariffs shall be made public by the competent authorities or the transmission system operator as appropriate.4.Transmission system operators may impose penalty charges on network users whose input into and offtake from the transmission system is not in balance according to the balancing rules referred to in paragraph 1.5.Penalty charges which exceed the actual balancing costs incurred, insofar as such costs correspond to those of an efficient and structurally comparable network operator and are transparent, shall be taken into account when calculating tariffs in a way that does not reduce the interest in balancing and shall be approved by the competent authorities.6.In order to enable network users to take timely corrective action, transmission system operators shall provide sufficient, well-timed and reliable on-line based information on the balancing status of network users. The level of information provided shall reflect the level of information available to the transmission system operator. Where they exist, charges for the provision of such information shall be approved by the competent authorities and shall be made public by the transmission system operator.7.Member States shall ensure that transmission system operators endeavour to harmonise balancing regimes and streamline structures and levels of balancing charges in order to facilitate gas trade.

Article 8Trading of capacity rightsEach transmission system operator shall take reasonable steps to allow capacity rights to be freely tradable and to facilitate such trade. Each such operator shall develop harmonised transportation contracts and procedures on the primary market to facilitate secondary trade of capacity and recognise the transfer of primary capacity rights where notified by network users. The harmonised transportation contracts and procedures shall be notified to the regulatory authorities.

Article 9Guidelines1.Where appropriate, Guidelines providing the minimum degree of harmonisation required to achieve the aim of this Regulation shall specify:(a)details of third party access services including the character, duration and other requirements of these services, in accordance with Article 4;(b)details of the principles underlying capacity allocation mechanisms and on the application of congestion management procedures in the event of contractual congestion, in accordance with Article 5;(c)details on the definition of the technical information necessary for network users to gain effective access to the system and the definition of all relevant points for transparency requirements, including the information to be published at all relevant points and the time schedule according to which this information shall be published, in accordance with Article 6.2.Guidelines on the issues listed in paragraph 1 are laid down in the Annex. They may be amended by the Commission; this shall be done in accordance with the procedure referred to in Article 14(2).3.The application and amendment of Guidelines adopted pursuant to this Regulation shall reflect differences between national gas systems, and shall therefore not require uniform detailed terms and conditions of third party access at Community level. They may, however, set minimum requirements to be met to achieve non-discriminatory and transparent network access conditions necessary for an internal gas market, which may then be applied in the light of differences between national gas systems.

Article 10Regulatory authoritiesWhen carrying out their responsibilities under this Regulation, the regulatory authorities of the Member States established under Article 25 of Directive 2003/55/EC shall ensure compliance with this Regulation and the Guidelines adopted pursuant to Article 9 of this Regulation.Where appropriate they shall cooperate with each other and with the Commission.

Article 11Provision of informationMember States and the regulatory authorities shall, on request, provide to the Commission all information necessary for the purposes of Article 9.The Commission shall fix a reasonable time limit within which the information is to be provided, taking into account the complexity of the information required and the urgency with which the information is needed.

Article 12Right of Member States to provide for more detailed measuresThis Regulation shall be without prejudice to the rights of Member States to maintain or introduce measures that contain more detailed provisions than those set out in this Regulation and the Guidelines referred to in Article 9.

Article 13Penalties1.The Member States shall lay down the rules on penalties applicable to infringements of the provisions of this Regulation and shall take all measures necessary to ensure that they are implemented. The penalties provided for must be effective, proportionate and dissuasive. The Member States shall notify those provisions to the Commission by 1 July 2006 at the latest and shall notify it without delay of any subsequent amendment affecting them.2.Penalties provided for pursuant to paragraph 1 shall not be of a criminal law nature.

Article 14Committee procedure1.The Commission shall be assisted by the Committee set up by Article 30 of Directive 2003/55/EC.2.Where reference is made to this paragraph, Articles 5 and 7 of Decision 1999/468/EC shall apply, having regard to the provisions of Article 8 thereof.The period laid down in Article 5(6) of Decision 1999/468/EC shall be set at three months.3.The Committee shall adopt its Rules of Procedure.

Article 15Commission reportThe Commission shall monitor the implementation of this Regulation. In its report under Article 31(3) of Directive 2003/55/EC, the Commission shall also report on the experience gained in the application of this Regulation. In particular the report shall examine to what extent the Regulation has been successful in ensuring non-discriminatory and cost-reflective network access conditions for gas transmission networks in order to contribute to customer choice in a well functioning internal market and to long-term security of supply. If necessary, the report shall be accompanied by appropriate proposals and/or recommendations.

Article 16Derogations and exemptionsThis Regulation shall not apply to:(a)natural gas transmission systems situated in Member States for the duration of derogations granted under Article 28 of Directive 2003/55/EC; Member States which have been granted derogations under Article 28 of Directive 2003/55/EC may apply to the Commission for a temporary derogation from the application of this Regulation, for a period of up to two years from the date at which the derogation referred to in this point expires;(b)interconnectors between Member States and significant increases of capacity in existing infrastructures and modifications of such infrastructures which enable the development of new sources of gas supply as referred to in Article 22(1) and (2) of Directive 2003/55/EC which are exempted from the provisions of Articles 18, 19, 20 and 25(2), (3) and (4) of that Directive as long as they are exempted from the provisions referred to in this subparagraph; or(c)natural gas transmission systems which have been granted derogations under Article 27 of Directive 2003/55/EC.
