Directive 2009/73/EC of the European Parliament and of the CouncilShow full title

Article 33 Access to storage

1. For the organisation of access to storage facilities and linepack when technically and/or economically necessary for providing efficient access to the system for the supply of customers, as well as for the organisation of access to ancillary services, Member States may choose either or both of the procedures referred to in paragraphs 3 and 4. Those procedures shall operate in accordance with objective, transparent and non-discriminatory criteria.

The regulatory authorities where Member States have so provided or Member States shall define and publish criteria according to which the access regime applicable to storage facilities and linepack may be determined. They shall make public, or oblige storage and transmission system operators to make public, which storage facilities, or which parts of those storage facilities, and which linepack is offered under the different procedures referred to in paragraphs 3 and 4.

The obligation referred to in the second sentence of the second subparagraph shall be without prejudice to the right of choice granted to Member States in the first subparagraph.

2. The provisions of paragraph 1 shall not apply to ancillary services and temporary storage that are related to LNG facilities and are necessary for the re-gasification process and subsequent delivery to the transmission system.

3. In the case of negotiated access, Member States or, where Member States have so provided, the regulatory authorities shall take the necessary measures for natural gas undertakings and eligible customers either inside or outside the territory covered by the interconnected system to be able to negotiate access to storage facilities and linepack, when technically and/or economically necessary for providing efficient access to the system, as well as for the organisation of access to other ancillary services. The parties shall be obliged to negotiate access to storage, linepack and other ancillary services in good faith.

Contracts for access to storage, linepack and other ancillary services shall be negotiated with the relevant storage system operator or natural gas undertakings. The regulatory authorities where Member States have so provided or Member States shall require storage system operators and natural gas undertakings to publish their main commercial conditions for the use of storage, linepack and other ancillary services by 1 January 2005 and on an annual basis every year thereafter.

When developing the conditions referred to in the second subparagraph, storage operators and natural gas undertakings shall consult system users.

4. In the case of regulated access, the regulatory authorities where Member States have so provided or Member States shall take the necessary measures to give natural gas undertakings and eligible customers either inside or outside the territory covered by the interconnected system a right to access to storage, linepack and other ancillary services, on the basis of published tariffs and/or other terms and obligations for use of that storage and linepack, when technically and/or economically necessary for providing efficient access to the system, as well as for the organisation of access to other ancillary services. The regulatory authorities where Member States have so provided or Member States shall consult system users when developing those tariffs or the methodologies for those tariffs. The right of access for eligible customers may be given by enabling them to enter into supply contracts with competing natural gas undertakings other than the owner and/or operator of the system or a related undertaking.
