Directive 2009/73/EC of the European Parliament and of the Council of 13 July 2009 concerning common rules for the internal market in natural gas and repealing Directive 2003/55/EC (Text with EEA relevance)

This Directive establishes common rules for the transmission, distribution, supply and storage of natural gas. It lays down the rules relating to the organisation and functioning of the natural gas sector, access to the market, the criteria and procedures applicable to the granting of authorisations for transmission, distribution, supply and storage of natural gas and the operation of systems.

The rules established by this Directive for natural gas, including LNG, shall also apply in a non-discriminatory way to biogas and gas from biomass or other types of gas in so far as such gases can technically and safely be injected into, and transported through, the natural gas system.

Member States shall ensure, on the basis of their institutional organisation and with due regard to the principle of subsidiarity, that, without prejudice to paragraph 2, natural gas undertakings are operated in accordance with the principles of this Directive with a view to achieving a competitive, secure and environmentally sustainable market in natural gas, and shall not discriminate between those undertakings as regards their rights or obligations.

Having full regard to the relevant provisions of the Treaty, in particular Article 86 thereof, Member States may impose on undertakings operating in the gas sector, in the general economic interest, public service obligations which may relate to security, including security of supply, regularity, quality and price of supplies, and environmental protection, including energy efficiency, energy from renewable sources and climate protection. Such obligations shall be clearly defined, transparent, non-discriminatory, verifiable and shall guarantee equality of access for natural gas undertakings of the Community to national consumers. In relation to security of supply, energy efficiency/demand-side management and for the fulfilment of environmental goals and goals for energy from renewable sources, as referred to in this paragraph, Member States may introduce the implementation of long-term planning, taking into account the possibility of third parties seeking access to the system.

Member States shall take appropriate measures to protect final customers, and shall, in particular, ensure that there are adequate safeguards to protect vulnerable customers. In this context, each Member State shall define the concept of vulnerable customers which may refer to energy poverty and, inter alia, to the prohibition of disconnection of gas to such customers in critical times. Member States shall ensure that rights and obligations linked to vulnerable customers are applied. In particular, they shall take appropriate measures to protect final customers in remote areas who are connected to the gas system. Member States may appoint a supplier of last resort for customers connected to the gas system. They shall ensure high levels of consumer protection, particularly with respect to transparency regarding contractual terms and conditions, general information and dispute settlement mechanisms. Member States shall ensure that the eligible customer is in fact able easily to switch to a new supplier. As regards at least household customers those measures shall include those set out in Annex I.

Member States shall take appropriate measures, such as formulating national energy action plans, providing social security benefits to ensure the necessary gas supply to vulnerable customers, or providing for support for energy efficiency improvements, to address energy poverty where identified, including in the broader context of poverty. Such measures shall not impede the effective opening of the market set out in Article 37 and market functioning and shall be notified to the Commission, where relevant, in accordance with paragraph 11 of this Article. Such notification shall not include measures taken within the general social security system.

Member States shall ensure that all customers connected to the gas network are entitled to have their gas provided by a supplier, subject to the supplier's agreement, regardless of the Member State in which the supplier is registered, as long as the supplier follows the applicable trading and balancing rules and subject to security of supply requirements. In this regard, Member States shall take all measures necessary to ensure that administrative procedures do not constitute a barrier for supply undertakings already registered in another Member State.

Member States shall ensure that:

Member States shall implement appropriate measures to achieve the objectives of social and economic cohesion and environmental protection, which may include means to combat climate change, and security of supply. Such measures may include, in particular, the provision of adequate economic incentives, using, where appropriate, all existing national and Community tools, for the maintenance and construction of necessary network infrastructure, including interconnection capacity.

In order to promote energy efficiency, Member States or, where a Member State has so provided, the regulatory authority shall strongly recommend that natural gas undertakings optimise the use of gas, for example by providing energy management services, developing innovative pricing formulas or introducing intelligent metering systems or smart grids where appropriate.

Member States shall ensure the provision of single points of contact to provide consumers with all necessary information concerning their rights, current legislation and the means of dispute settlement available to them in the event of a dispute. Such contact points may be part of general consumer information points.

Member States may decide not to apply the provisions of Article 4 with respect to distribution insofar as their application would obstruct, in law or in fact, the performance of the obligations imposed on natural gas undertakings in the general economic interest and insofar as the development of trade would not be affected to such an extent as would be contrary to the interests of the Community. The interests of the Community include, inter alia, competition with regard to eligible customers in accordance with this Directive and Article 86 of the Treaty.

Member States shall, upon implementation of this Directive, inform the Commission of all measures adopted to fulfil public service obligations, including consumer and environmental protection, and their possible effect on national and international competition, whether or not such measures require a derogation from the provisions of this Directive. They shall notify the Commission subsequently every two years of any changes to such measures, whether or not they require a derogation from this Directive.

The Commission shall establish, in consultation with relevant stakeholders, including Member States, the national regulatory authorities, consumer organisations and natural gas undertakings, a clear and concise energy consumer checklist of practical information relating to energy consumer rights. Member States shall ensure that gas suppliers or distribution system operators, in cooperation with the regulatory authority, take the necessary steps to provide their consumers with a copy of the energy consumer checklist and ensure that it is made publicly available.

In circumstances where an authorisation (for example, licence, permission, concession, consent or approval) is required for the construction or operation of natural gas facilities, the Member States or any competent authority they designate shall grant authorisations to build and/or operate such facilities, pipelines and associated equipment on their territory, in accordance with paragraphs 2 to 4. Member States or any competent authority they designate may also grant authorisations on the same basis for the supply of natural gas and for wholesale customers.

Where Member States have a system of authorisation, they shall lay down objective and non-discriminatory criteria which shall be met by an undertaking applying for an authorisation to build and/or operate natural gas facilities or applying for an authorisation to supply natural gas. The non-discriminatory criteria and procedures for the granting of authorisations shall be made public. Member States shall ensure that authorisation procedures for facilities, pipelines and associated equipment take into account the importance of the project for the internal market in natural gas where appropriate.

Member States shall ensure that the reasons for any refusal to grant an authorisation are objective and non-discriminatory and that they are given to the applicant. Reasons for such refusals shall be notified to the Commission for information. Member States shall establish a procedure enabling the applicant to appeal against such refusals.

For the development of newly supplied areas and efficient operation generally, and without prejudice to Article 38, Member States may decline to grant a further authorisation to build and operate distribution pipeline systems in any particular area once such pipeline systems have been or are proposed to be built in that area and if existing or proposed capacity is not saturated.

In order to safeguard a secure supply on the internal market in natural gas, Member States shall cooperate in order to promote regional and bilateral solidarity.

Such cooperation shall cover situations resulting or likely to result in the short term in a severe disruption of supply affecting a Member State. It shall include:

The Commission and the other Member States shall be kept informed of such cooperation.

The Commission may adopt Guidelines for regional cooperation in a spirit of solidarity. Those measures, designed to amend non-essential elements of this Directive by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 51(3).

Member States as well as the regulatory authorities shall cooperate with each other for the purpose of integrating their national markets at one and more regional levels, as a first step towards the creation of a fully liberalised internal market. In particular, the regulatory authorities where Member States have so provided or Member States shall promote and facilitate the cooperation of transmission system operators at a regional level, including on cross-border issues with the aim of creating a competitive internal market in natural gas, foster the consistency of their legal, regulatory and technical framework and facilitate integration of the isolated systems forming gas islands that persist in the Community. The geographical areas covered by such regional cooperation shall include cooperation in geographical areas defined in accordance with Article 12(3) of Regulation (EC) No 715/2009. Such cooperation may cover other geographical areas.

The Agency shall cooperate with national regulatory authorities and transmission system operators to ensure the compatibility of regulatory frameworks between the regions with the aim of creating a competitive internal market in natural gas. Where the Agency considers that binding rules on such cooperation are required, it shall make appropriate recommendations.

Member States shall ensure, through the implementation of this Directive, that transmission system operators have one or more integrated system(s) at regional level covering two or more Member States for capacity allocation and for checking the security of the network.

Where vertically integrated transmission system operators participate in a joint undertaking established for implementing such cooperation, the joint undertaking shall establish and implement a compliance programme which sets out the measures to be taken to ensure that discriminatory and anticompetitive conduct is excluded. That compliance programme shall set out the specific obligations of employees to meet the objective of excluding discriminatory and anticompetitive conduct. It shall be subject to the approval of the Agency. Compliance with the programme shall be independently monitored by the compliance officers of the vertically integrated transmission system operators.

Member States shall ensure that from 3 March 2012:

The rights referred to in points (b) and (c) of paragraph 1 shall include, in particular:

For the purpose of paragraph 1(b), the notion ‘undertaking performing any of the functions of production or supply’ shall include ‘undertaking performing any of the functions of generation and supply’ within the meaning of Directive 2009/72/EC of the European Parliament and of the Council of 13 July 2009 concerning common rules for the internal market in electricity ([^E0006]), and the terms ‘transmission system operator’ and ‘transmission system’ shall include ‘transmission system operator’ and ‘transmission system’ within the meaning of that Directive.

Member States may allow for derogations from points (b) and (c) of paragraphs 1 until 3 March 2013, provided that transmission system operators are not part of a vertically integrated undertaking.

The obligation set out in paragraph 1(a) of this Article shall be deemed to be fulfilled in a situation where two or more undertakings which own transmission systems have created a joint venture which acts as a transmission system operator in two or more Member States for the transmission systems concerned. No other undertaking may be part of the joint venture, unless it has been approved under Article 14 as an independent system operator or as an independent transmission operator for the purposes of Chapter IV.

For the implementation of this Article, where the person referred to in points (b), (c) and (d) of paragraph 1 is the Member State or another public body, two separate public bodies exercising control over a transmission system operator or over a transmission system on the one hand, and over an undertaking performing any of the functions of production or supply on the other, shall be deemed not to be the same person or persons.

Member States shall ensure that neither commercially sensitive information referred to in Article 16 held by a transmission system operator which was part of a vertically integrated undertaking, nor the staff of such a transmission system operator, is transferred to undertakings performing any of the functions of production and supply.

Where on 3 September 2009 the transmission system belonged to a vertically integrated undertaking, a Member State may decide not to apply paragraph 1. As regards the part of the transmission system connecting a Member State with a third country between the border of that Member State and the first connection point with that Member State's network, where on 23 May 2019 the transmission system belongs to a vertically integrated undertaking, a Member State may decide not to apply paragraph 1.

Where on 3 September 2009 the transmission system belonged to a vertically integrated undertaking and arrangements are in place which guarantee more effective independence of the transmission system operator than the provisions of Chapter IV, a Member State may decide not to apply paragraph 1 of this Article.

Before an undertaking is approved and designated as a transmission system operator under paragraph 9 of this Article, it shall be certified according to the procedures laid down in Article 10(4), (5) and (6) of this Directive and in Article 3 of Regulation (EC) No 715/2009, pursuant to which the Commission shall verify that the arrangements in place clearly guarantee more effective independence of the transmission system operator than the provisions of Chapter IV.

Vertically integrated undertakings which own a transmission system shall not in any event be prevented from taking steps to comply with paragraph 1.

Undertakings performing any of the functions of production or supply shall not in any event be able to directly or indirectly take control over or exercise any right over unbundled transmission system operators in Member States which apply paragraph 1.

Before an undertaking is approved and designated as transmission system operator, it shall be certified according to the procedures laid down in paragraphs 4, 5 and 6 of this Article and in Article 3 of Regulation (EC) No 715/2009.

Undertakings which own a transmission system and which have been certified by the national regulatory authority as having complied with the requirements of Article 9, pursuant to the certification procedure, shall be approved and designated as transmission system operators by Member States. The designation of transmission system operators shall be notified to the Commission and published in the Official Journal of the European Union.

Transmission system operators shall notify to the regulatory authority any planned transaction which may require a reassessment of their compliance with the requirements of Article 9.

The regulatory authorities shall monitor the continuing compliance of transmission system operators with the requirements of Article 9. They shall open a certification procedure to ensure such compliance:

The regulatory authorities shall adopt a decision on the certification of a transmission system operator within a period of four months from the date of the notification by the transmission system operator or from the date of the Commission request. After expiry of that period, the certification shall be deemed to be granted. The explicit or tacit decision of the regulatory authority shall become effective only after the conclusion of the procedure set out in paragraph 6.

The explicit or tacit decision on the certification of a transmission system operator shall be notified without delay to the Commission by the regulatory authority, together with all the relevant information with respect to that decision. The Commission shall act in accordance with the procedure laid down in Article 3 of Regulation (EC) No 715/2009.

The regulatory authorities and the Commission may request from transmission system operators and undertakings performing any of the functions of production or supply any information relevant for the fulfilment of their tasks under this Article.

The regulatory authorities and the Commission shall preserve the confidentiality of commercially sensitive information.

Where certification is requested by a transmission system owner or a transmission system operator which is controlled by a person or persons from a third country or third countries, the regulatory authority shall notify the Commission.

The transmission system operator shall notify to the regulatory authority any circumstances that would result in a person or persons from a third country or third countries acquiring control of the transmission system or the transmission system operator.

The regulatory authority shall adopt a draft decision on the certification of a transmission system operator within four months from the date of notification by the transmission system operator. It shall refuse the certification if it has not been demonstrated:

The regulatory authority shall notify the decision to the Commission without delay, together with all the relevant information with respect to that decision.

Member States shall provide for the regulatory authority or the designated competent authority referred to in paragraph 3(b), before the regulatory authority adopts a decision on the certification, to request an opinion from the Commission on whether:

The Commission shall examine the request referred to in paragraph 5 as soon as it is received. Within a period of two months after receiving the request, it shall deliver its opinion to the national regulatory authority or, if the request was made by the designated competent authority, to that authority.

When assessing whether the control by a person or persons from a third country or third countries will put at risk the security of energy supply to the Community, the Commission shall take into account:

The national regulatory authority shall, within a period of two months after the expiry of the period referred to in paragraph 6, adopt its final decision on the certification. In adopting its final decision the national regulatory authority shall take utmost account of the Commission’s opinion. In any event Member States shall have the right to refuse certification where granting certification puts at risk the Member State’s security of energy supply or the security of energy supply of another Member State. Where the Member State has designated another competent authority to assess paragraph 3(b), it may require the national regulatory authority to adopt its final decision in accordance with the assessment of that competent authority. The regulatory authority’s final decision and the Commission’s opinion shall be published together. Where the final decision diverges from the Commission’s opinion, the Member State concerned shall provide and publish, together with that decision, the reasoning underlying such decision.

Nothing in this Article shall affect the right of Member States to exercise, in compliance with Community law, national legal controls to protect legitimate public security interests.

The Commission may adopt Guidelines setting out the details of the procedure to be followed for the application of this Article. Those measures, designed to amend non-essential elements of this Directive by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 51(3).

This Article, with exception of paragraph 3(a), shall also apply to Member States which are subject to a derogation under Article 49.

Each transmission, storage and/or LNG system operator shall:

Each transmission system operator shall build sufficient cross-border capacity to integrate European transmission infrastructure accommodating all economically reasonable and technically feasible demands for capacity and taking into account security of gas supply.

Rules adopted by transmission system operators for balancing the gas transmission system shall be objective, transparent and non-discriminatory, including rules for the charging of system users of their networks for energy imbalance. Terms and conditions, including rules and tariffs, for the provision of such services by transmission system operators shall be established pursuant to a methodology compatible with Article 41(6) in a non-discriminatory and cost-reflective way and shall be published.

The regulatory authorities where Member States have so provided or Member States may require transmission system operators to comply with minimum standards for the maintenance and development of the transmission system, including interconnection capacity.

Transmission system operators shall procure the energy they use for the carrying out of their functions according to transparent, non-discriminatory and market based procedures.

Where on 3 September 2009 the transmission system belonged to a vertically integrated undertaking, a Member State may decide not to apply Article 9(1) and to designate an independent system operator upon a proposal from the transmission system owner.

The Member State may approve and designate an independent system operator only where:

Undertakings which have been certified by the regulatory authority as having complied with the requirements of Article 11 and of paragraph 2 of this Article shall be approved and designated as independent system operators by Member States. The certification procedure in either Article 10 of this Directive and Article 3 of Regulation (EC) No 715/2009 or in Article 11 of this Directive shall be applicable.

Each independent system operator shall be responsible for granting and managing third-party access, including the collection of access charges and congestion charges, for operating, maintaining and developing the transmission system, as well as for ensuring the long-term ability of the system to meet reasonable demand through investment planning. When developing the transmission system the independent system operator shall be responsible for planning (including authorisation procedure), construction and commissioning of the new infrastructure. For this purpose, the independent system operator shall act as a transmission system operator in accordance with this Chapter. The transmission system owner shall not be responsible for granting and managing third-party access, nor for investment planning.

Where an independent system operator has been designated, the transmission system owner shall:

In close cooperation with the regulatory authority, the relevant national competition authority shall be granted all relevant powers to effectively monitor compliance of the transmission system owner with its obligations under paragraph 5.

A transmission system owner, where an independent system operator has been appointed, and a storage system operator which are part of vertically integrated undertakings shall be independent at least in terms of their legal form, organisation and decision making from other activities not relating to transmission, distribution and storage.

In order to ensure the independence of the transmission system owner and storage system operator referred to in paragraph 1, the following minimum criteria shall apply:

The Commission may adopt Guidelines to ensure full and effective compliance of the transmission system owner and of the storage system operator with paragraph 2 of this Article. Those measures, designed to amend non-essential elements of this Directive by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 51(3).

Without prejudice to Article 30 or any other legal duty to disclose information, each transmission, storage and/or LNG system operator, and each transmission system owner, shall preserve the confidentiality of commercially sensitive information obtained in the course of carrying out its activities, and shall prevent information about its own activities which may be commercially advantageous from being disclosed in a discriminatory manner. In particular, it shall not disclose any commercially sensitive information to the remaining parts of the undertaking, unless this is necessary for carrying out a business transaction. In order to ensure the full respect of the rules on information unbundling, Member States shall ensure that the transmission system owner including, in the case of a combined operator, the distribution system operator, and the remaining part of the undertaking do not use joint services, such as joint legal services, apart from purely administrative or IT functions.

Transmission, storage and/or LNG system operators shall not, in the context of sales or purchases of natural gas by related undertakings, misuse commercially sensitive information obtained from third parties in the context of providing or negotiating access to the system.

Information necessary for effective competition and the efficient functioning of the market shall be made public. That obligation shall be without prejudice to protecting commercially sensitive information.

Paragraph 3 shall apply to the majority of the persons responsible for the management and/or members of the administrative bodies of the transmission system operator.

The transmission system operator shall have a Supervisory Body which shall be in charge of taking decisions which may have a significant impact on the value of the assets of the shareholders within the transmission system operator, in particular decisions regarding the approval of the annual and longer-term financial plans, the level of indebtedness of the transmission system operator and the amount of dividends distributed to shareholders. The decisions falling under the remit of the Supervisory Body shall exclude those that are related to the day to day activities of the transmission system operator and management of the network, and in relation to activities necessary for the preparation of the ten-year network development plan developed pursuant to Article 22.

The Supervisory Body shall be composed of members representing the vertically integrated undertaking, members representing third party shareholders and, where the relevant legislation of a Member State so provides, members representing other interested parties such as employees of the transmission system operator.

The first subparagraph of Article 19(2) and Article 19(3) to (7) shall apply to at least half of the members of the Supervisory Body minus one.

Member States shall ensure that transmission system operators establish and implement a compliance programme which sets out the measures taken in order to ensure that discriminatory conduct is excluded, and ensure that the compliance with that programme is adequately monitored. The compliance programme shall set out the specific obligations of employees to meet those objectives. It shall be subject to approval by the regulatory authority. Without prejudice to the powers of the national regulator, compliance with the program shall be independently monitored by a compliance officer.

The compliance officer shall be appointed by the Supervisory Body, subject to the approval by the regulatory authority. The regulatory authority may refuse the approval of the compliance officer only for reasons of lack of independence or professional capacity. The compliance officer may be a natural or legal person. Article 19(2) to (8) shall apply to the compliance officer.

The compliance officer shall be in charge of:

The compliance officer shall submit the proposed decisions on the investment plan or on individual investments in the network to the regulatory authority. This shall occur at the latest when the management and/or the competent administrative body of the transmission system operator submits them to the Supervisory Body.

Where the vertically integrated undertaking, in the general assembly or through the vote of the members of the Supervisory Body it has appointed, has prevented the adoption of a decision with the effect of preventing or delaying investments, which under the ten-year network development plan, was to be executed in the following three years, the compliance officer shall report this to the regulatory authority, which then shall act in accordance with Article 22.

The conditions governing the mandate or the employment conditions of the compliance officer, including the duration of his mandate, shall be subject to approval by the regulatory authority. Those conditions shall ensure the independence of the compliance officer, including by providing it with all the resources necessary for fulfilling his duties.
