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

Article 15 Unbundling of transmission system owners and storage system operators

1. 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.

This Article shall apply only to storage facilities that are technically and/or economically necessary for providing efficient access to the system for the supply of customers pursuant to Article 33.

2. 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:

(a) persons responsible for the management of the transmission system owner and storage system operator shall not participate in company structures of the integrated natural gas undertaking responsible, directly or indirectly, for the day-to-day operation of the production and supply of natural gas;

(b) appropriate measures shall be taken to ensure that the professional interests of persons responsible for the management of the transmission system owner and storage system operator are taken into account in a manner that ensures that they are capable of acting independently;

(c) the storage system operator shall have effective decision-making rights, independent from the integrated natural gas undertaking, with respect to assets necessary to operate, maintain or develop the storage facilities. This shall not preclude the existence of appropriate coordination mechanisms to ensure that the economic and management supervision rights of the parent company in respect of return on assets regulated indirectly in accordance with Article 41(6) in a subsidiary are protected. In particular, this shall enable the parent company to approve the annual financial plan, or any equivalent instrument, of the storage system operator and to set global limits on the levels of indebtedness of its subsidiary. It shall not permit the parent company to give instructions regarding day-to-day operations, nor with respect to individual decisions concerning the construction or upgrading of storage facilities, that do not exceed the terms of the approved financial plan, or any equivalent instrument; and

(d) the transmission system owner and the storage system operator shall establish a compliance programme, which sets out measures taken to ensure that discriminatory conduct is excluded, and ensure that observance of it is adequately monitored. The compliance programme shall set out the specific obligations of employees to meet those objectives. An annual report, setting out the measures taken, shall be submitted by the person or body responsible for monitoring the compliance programme to the regulatory authority and shall be published.

3. 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).
