Upon a reasoned request from the Agency, the Commission may extend that period.

The Agency shall formally consult the ENTSO for Gas and the other relevant stakeholders in regard to the framework guideline, during a period of no less than two months, in an open and transparent manner.

If the Commission considers that the framework guideline does not contribute to non-discrimination, effective competition and the efficient functioning of the market, it may request the Agency to review the framework guideline within a reasonable period of time and re-submit it to the Commission.

If the Agency fails to submit or re-submit a framework guideline within the period set by the Commission under paragraphs 2 or 4, the Commission shall elaborate the framework guideline in question.

The Commission shall request the ENTSO for Gas to submit a network code which is in line with the relevant framework guideline, to the Agency within a reasonable period of time not exceeding 12 months.

Within a period of three months after the day of receipt of a network code, during which the Agency may formally consult the relevant stakeholders, the Agency shall provide a reasoned opinion to the ENTSO for Gas on the network code.

The ENTSO for Gas may amend the network code in the light of the opinion of the Agency and re-submit it to the Agency.

Once the Agency is satisfied that the network code is in line with the relevant framework guideline, the Agency shall submit the network code to the Commission and may recommend that it be adopted within a reasonable time period. The Commission shall provide reasons in the event that it does not adopt that network code.

Where the ENTSO for Gas has failed to develop a network code within the period of time set by the Commission under paragraph 6, the Commission may request the Agency to prepare a draft network code on the basis of the relevant framework guideline. The Agency may launch a further consultation in the course of preparing a draft network code under this paragraph. The Agency shall submit a draft network code prepared under this paragraph to the Commission and may recommend that it be adopted.

The Commission may adopt, on its own initiative where the ENTSO for Gas has failed to develop a network code, or the Agency has failed to develop a draft network code as referred to in paragraph 10 of this Article, or upon recommendation of the Agency under paragraph 9 of this Article, one or more network codes in the areas listed in Article 8(6).
Where the Commission proposes to adopt a network code on its own initiative, the Commission shall consult the Agency, the ENTSO for Gas and all relevant stakeholders in regard to the draft network code during a period of no less than two months. Those measures, designed to amend non-essential elements of this Regulation by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 28(2).

This Article shall be without prejudice to the Commission's right to adopt and amend the Guidelines as laid down in Article 23.

In regard to point (c) of the second subparagraph, a review of barriers to the increase of cross-border capacity of the network arising from different approval procedures or practices may be annexed to the Community-wide network development plan.

The Agency shall review national ten-year network development plans to assess their consistency with the Community-wide network development plan. If the Agency identifies inconsistencies between a national ten-year network development plan and the Community-wide network development plan, it shall recommend amending the national ten-year network development plan or the Community-wide network development plan as appropriate. If such national ten-year network development plan is elaborated in accordance with Article 22 of CRIMINGD, the Agency shall recommend that the competent national regulatory authority amend the national ten-year network development plan in accordance with Article 22(7) of that Directive and inform the Commission thereof.

Upon request of the Commission, the ENTSO for Gas shall give its views to the Commission on the adoption of the Guidelines as laid down in Article 23.

The Agency shall monitor the execution of the tasks referred to in Article 8(1), (2) and (3) of the ENTSO for Gas and report to the Commission.
The Agency shall monitor the implementation by the ENTSO for Gas of network codes elaborated under Article 8(2) and network codes which have been developed in accordance with Article 6(1) to (10) but which have not been adopted by the Commission under Article 6(11). Where the ENTSO for Gas has failed to implement such network codes, the Agency shall request the ENTSO for Gas to provide a duly reasoned explanation as to why it has failed to do so. The Agency shall inform the Commission of that explanation and provide its opinion thereon.
The Agency shall monitor and analyse the implementation of the network codes and the Guidelines adopted by the Commission as laid down in Article 6(11), and their effect on the harmonisation of applicable rules aimed at facilitating market integration as well as on non-discrimination, effective competition and the efficient functioning of the market, and report to the Commission.

The ENTSO for Gas shall submit the draft Community-wide network development plan, the draft annual work programme, including the information regarding the consultation process and the other documents referred to in Article 8(3), to the Agency for its opinion.
Within two months from the day of receipt, the Agency shall provide a duly reasoned opinion as well as recommendations to the ENTSO for Gas and to the Commission where it considers that the draft annual work programme or the draft Community-wide network development plan submitted by the ENTSO for Gas do not contribute to non-discrimination, effective competition, the efficient functioning of the market or a sufficient level of cross-border interconnection open to third-party access.

While preparing the network codes, the draft Community-wide network development plan and the annual work programme referred to in Article 8(1), (2) and (3), the ENTSO for Gas shall conduct an extensive consultation process, at an early stage and in an open and transparent manner, involving all relevant market participants, and, in particular, the organisations representing all stakeholders, in accordance with the rules of procedure referred to in Article 5(1). That consultation shall also involve national regulatory authorities and other national authorities, supply and production undertakings, network users including customers, distribution system operators, including relevant industry associations, technical bodies and stakeholder platforms. It shall aim at identifying the views and proposals of all relevant parties during the decision-making process.

All documents and minutes of meetings related to the consultations referred to in paragraph 1 shall be made public.

Before adopting the annual work programme and the network codes referred to in Article 8(1), (2) and (3), the ENTSO for Gas shall indicate how the observations received during the consultation have been taken into consideration. It shall provide reasons where observations have not been taken into account.

The costs related with the activities of the ENTSO for Gas referred to in Articles 4 to 12 shall be borne by the transmission system operators and shall be taken into account in the calculation of tariffs. Regulatory authorities shall approve those costs only if they are reasonable and proportionate.

Transmission system operators shall establish regional cooperation within the ENTSO for Gas to contribute to the tasks referred to in Article 8(1), (2) and (3). In particular, they shall publish a regional investment plan every two years, and may take investment decisions based on that regional investment plan.

Transmission system operators shall promote operational arrangements in order to ensure the optimum management of the network and shall promote the development of energy exchanges, the coordinated allocation of cross-border capacity through non-discriminatory market-based solutions, paying due attention to the specific merits of implicit auctions for short-term allocations and the integration of balancing mechanisms.

For the purposes of achieving the goals set in paragraphs 1 and 2, the geographical area covered by each regional cooperation structure may be defined by the Commission, taking into account existing regional cooperation structures. Each Member State shall be allowed to promote cooperation in more than one geographical area. The measure referred to in the first sentence, designed to amend non-essential elements of this Regulation by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 28(2).
For that purpose, the Commission shall consult the Agency and the ENTSO for Gas.

Tariffs, or the methodologies used to calculate them, applied by the transmission system operators and approved by the regulatory authorities pursuant to Article 41(6) of CRIMINGD, as well as tariffs published pursuant to Article 32(1) of that Directive, shall be transparent, take into account the need for system integrity and its improvement and reflect the actual costs incurred, insofar as such costs correspond to those of an efficient and structurally comparable network operator and are transparent, whilst including an 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.
Tariffs for network users shall be non-discriminatory and set separately for every entry point into or exit point out of the transmission system. Cost-allocation mechanisms and rate setting methodology regarding entry points and exit points shall be approved by the national regulatory authorities. By 3 September 2011, the Member States shall ensure that, after a transitional period, network charges shall not be calculated on the basis of contract paths.

Tariffs for network access shall neither 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 41(6) of CRIMINGD, 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.

Transmission system operators shall:

ensure that they offer services on a non-discriminatory basis to all network users;

provide both firm and interruptible third-party access services. The price of interruptible capacity shall reflect the probability of interruption;

offer to network users both long and short-term services.

In regard to point (a) of the first subparagraph, 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 transport contracts or a common network code approved by the competent authority in accordance with the procedure laid down in Article 41 of CRIMINGD.

Transport contracts signed with non-standard start dates or with a shorter duration than a standard annual transport contract shall not result in arbitrarily higher or lower tariffs that do not reflect the market value of the service, in accordance with the principles laid down in Article 13(1).

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 shall not constitute undue market-entry barriers and shall be non-discriminatory, transparent and proportionate.

LNG and storage system operators shall:

offer services on a non-discriminatory basis to all network users that accommodate market demand; in particular, where an LNG or storage system operator offers the same service to different customers, it shall do so under equivalent contractual terms and conditions;

offer services that are compatible with the use of the interconnected gas transport systems and facilitate access through cooperation with the transmission system operator; and

make relevant information public, in particular data on the use and availability of services, in a time-frame compatible with the LNG or storage facility users' reasonable commercial needs, subject to the monitoring of such publication by the national regulatory authority.

Each storage system operator shall:

provide both firm and interruptible third-party access services; the price of interruptible capacity shall reflect the probability of interruption;

offer to storage facility users both long and short-term services; and

offer to storage facility users both bundled and unbundled services of storage space, injectability and deliverability.

LNG and storage facility contracts shall not result in arbitrarily higher tariffs in cases in which they are signed:

outside a natural gas year with non-standard start dates; or

with a shorter duration than a standard LNG and storage facility contract on an annual basis.

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 shall not constitute undue market-entry barriers and shall be non-discriminatory, transparent and proportionate.

Contractual limits on the required minimum size of LNG facility capacity and storage capacity shall be justified on the basis of technical constrains and shall permit smaller storage users to gain access to storage services.

The maximum capacity at all relevant points referred to in Article 18(3) shall be made available to market participants, taking into account system integrity and efficient network operation.

The transmission system operator shall implement and publish non-discriminatory and transparent capacity-allocation mechanisms, which shall:

provide appropriate economic signals for the efficient and maximum use of technical capacity, facilitate investment in new infrastructure and facilitate cross-border exchanges in natural gas;

be compatible with the market mechanisms including spot markets and trading hubs, while being flexible and capable of adapting to evolving market circumstances; and

be compatible with the network access systems of the Member States.

The transmission system operator shall implement and publish non-discriminatory and transparent congestion-management procedures which facilitate cross-border exchanges in natural gas on a non-discriminatory basis and which shall be based on the following principles:

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; and

network users who wish to re-sell or sublet their unused contracted capacity on the secondary market shall be entitled to do so.

In regard to point (b) of the first subparagraph, a Member State may require notification or information of the transmission system operator by network users.

In the event that physical congestion exists, non-discriminatory, transparent capacity-allocation mechanisms shall be applied by the transmission system operator or, as appropriate, by the regulatory authorities.

Transmission system operators shall regularly assess market demand for new investment. When planning new investments, transmission system operators shall assess market demand and take into account security of supply.

The maximum storage and LNG facility capacity shall be made available to market participants, taking into account system integrity and operation.

LNG and storage system operators shall implement and publish non-discriminatory and transparent capacity-allocation mechanisms which shall:

provide appropriate economic signals for the efficient and maximum use of capacity and facilitate investment in new infrastructure;

be compatible with the market mechanism including spot markets and trading hubs, while being flexible and capable of adapting to evolving market circumstances; and

be compatible with the connected network access systems.

LNG and storage facility contracts shall include measures to prevent capacity-hoarding, by taking into account the following principles, which shall apply in cases of contractual congestion:

the system operator must offer unused LNG facility and storage capacity on the primary market without delay; for storage facilities this must be at least on a day-ahead and interruptible basis;

LNG and storage facility users who wish to re-sell their contracted capacity on the secondary market must be entitled to do so.

The transmission system operator shall make public detailed information regarding the services it offers and the relevant conditions applied, together with the technical information necessary for network users to gain effective network access.

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.

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 and standardised manner.

The relevant points of a transmission system on which the information is to be made public shall be approved by the competent authorities after consultation with network users.

The transmission system operator shall always disclose the information required by this Regulation in a meaningful, quantifiably clear and easily accessible manner and on a non-discriminatory basis.

The transmission system operator shall make public ex-ante and ex-post supply and demand information, based on nominations, forecasts and realised flows in and out of the system. The national regulatory authority shall ensure that all such information is made public. The level of detail of the information that is made public shall reflect the information available to the transmission system operator. ex-post
The transmission system operator shall make public measures taken as well as costs incurred and revenue generated to balance the system.
The market participants concerned shall provide the transmission system operator with the data referred to in this Article.

LNG and storage system operators shall make public detailed information regarding the services it offers and the relevant conditions applied, together with the technical information necessary for LNG and storage facility users to gain effective access to the LNG and storage facilities.

For the services provided, LNG and storage system operators shall make public information on contracted and available storage and LNG facility capacities on a numerical basis on a regular and rolling basis and in a user-friendly standardised manner.

LNG and storage 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.

LNG and storage system operators shall make public the amount of gas in each storage or LNG facility, or group of storage facilities if that corresponds to the way in which the access is offered to system users, inflows and outflows, and the available storage and LNG facility capacities, including for those facilities exempted from third-party access. That information shall also be communicated to the transmission system operator, which shall make it public on an aggregated level per system or subsystem defined by the relevant points. The information shall be updated at least daily.
In cases in which a storage system user is the only user of a storage facility, the storage system user may submit to the national regulatory authority a reasoned request for confidential treatment of the data referred to in the first subparagraph. Where the national regulatory authority comes to the conclusion that such a request is justified, taking into account, in particular, the need to balance the interest of legitimate protection of business secrets, the disclosure of which would negatively affect the overall commercial strategy of the storage user, with the objective of creating a competitive internal gas market, it may allow the storage system operator not to make public the data referred to in the first subparagraph, for a duration of up to one year.
The second subparagraph shall apply without prejudice to the obligations of communication to and publication by the transmission system operator referred to in the first subparagraph, unless the aggregated data are identical to the individual storage system data for which the national regulatory authority has approved non-publication.

In order to ensure transparent, objective and non-discriminatory tariffs and facilitate efficient utilisation of the infrastructures, the LNG and storage facility operators or relevant regulatory authorities shall make public sufficiently detailed information on tariff derivation, the methodologies and the structure of tariffs for infrastructure under regulated third-party access.

Transmission system operators, storage system operators and LNG system operators shall keep at the disposal of the national authorities, including the national regulatory authority, the national competition authority and the Commission, all information referred to in Articles 18 and 19, and in Part 3 of Annex I for a period of five years.

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. Balancing rules shall be market-based.

In order to enable network users to take timely corrective action, the transmission system operator shall provide sufficient, well-timed and reliable on-line based information on the balancing status of network users.
The information provided shall reflect the level of information available to the transmission system operator and the settlement period for which imbalance charges are calculated.
No charge shall be made for the provision of information under this paragraph.

Imbalance charges shall be cost-reflective to the extent possible, whilst providing appropriate incentives on network users to balance their input and off-take 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.

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.

Each transmission, storage and LNG system operator shall take reasonable steps to allow capacity rights to be freely tradable and to facilitate such trade in a transparent and non-discriminatory manner. Every such operator shall develop harmonised transport, LNG facility and storage contracts and procedures on the primary market to facilitate secondary trade of capacity and shall recognise the transfer of primary capacity rights where notified by system users.

Where appropriate, Guidelines providing the minimum degree of harmonisation required to achieve the aims of this Regulation shall specify:

details of third-party access services, including the character, duration and other requirements of those services, in accordance with Articles 14 and 15;

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 Articles 16 and 17;

details of the provision of information, 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 for the publication of that information, in accordance with Articles 18 and 19;

details of tariff methodology related to cross-border trade of natural gas, in accordance with Article 13;

details relating to the areas listed in Article 8(6).

For that purpose, the Commission shall consult the Agency and the ENTSO for Gas.

Guidelines on the issues listed in points (a), (b) and (c) of paragraph 1 are laid down in Annex I with respect to transmission system operators.
The Commission may adopt Guidelines on the issues listed in paragraph 1 of this Article and amend the Guidelines referred to in points (a), (b) and (c) thereof. Those measures, designed to amend non-essential elements of this Regulation, inter alia by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 28(2).

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 market in natural gas, which may then be applied in the light of differences between national gas systems.

When carrying out their responsibilities under this Regulation, the regulatory authorities shall ensure compliance with this Regulation and the Guidelines adopted pursuant to Article 23.

Member States and the regulatory authorities shall, on request, provide to the Commission all information necessary for the purposes of Article 23.

This 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 herein or in the Guidelines referred to in Article 23.

The Member States shall lay down rules on penalties applicable to infringements of the provisions of this Regulation and shall take all measures necessary to ensure that those provisions are implemented. The penalties provided for must be effective, proportionate and dissuasive. The Member States shall notify the Commission by 1 July 2006 of those rules corresponding to the provisions laid down in CANGTNR and shall notify the Commission without delay of any subsequent amendment affecting them. They shall notify the Commission of those rules not corresponding to the provisions laid down in CANGTNR by 3 September 2009 and shall notify the Commission without delay of any subsequent amendment affecting them.

Penalties provided for pursuant to paragraph 1 shall not be of a criminal law nature.

The Commission shall be assisted by the committee set up by Article 51 of CRIMINGD.

Where reference is made to this paragraph, Article 5 a(1) to (4) and Article 7 of Decision 1999/468/EC shall apply, having regard to the provisions of Article 8 thereof.

The Commission shall monitor the implementation of this Regulation. In its report under Article 52(6) of CRIMINGD, the Commission shall also report on the experience gained in the application of this Regulation. In particular, the report shall examine to what extent this 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.

This Regulation shall not apply to:

natural gas transmission systems situated in Member States for the duration of derogations granted under Article 49 of CRIMINGD;

major new infrastructure, i.e. interconnectors, LNG and storage facilities, and significant increases of capacity in existing infrastructure and modifications of such infrastructure which enable the development of new sources of gas supply referred to in Article 36(1) and (2) of CRIMINGD which are exempt from the provisions of Articles 9, 14, 32, 33, 34 or Article 41(6), (8) and (10) of that Directive as long as they are exempt from the provisions referred to in this subparagraph, with the exception of Article 19(4) of this Regulation; or

natural gas transmission systems which have been granted derogations under Article 48 of CRIMINGD.

As regards point (a) of the first subparagraph, Member States that have been granted derogations under Article 49 of CRIMINGD 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 on which the derogation referred to in that point expires.

CANGTNR shall be repealed from 3 March 2011. References made to the repealed Regulation shall be construed as references to this Regulation and shall be read in accordance with the correlation table in Annex II.
