1. Market participants shall publicly disclose in an effective and timely manner inside information which they possess in respect of business or facilities which the market participant concerned, or its parent undertaking or related undertaking, owns or controls or for whose operational matters that market participant or undertaking is responsible, either in whole or in part. Such disclosure shall include information relevant to the capacity and use of facilities for production, storage, consumption or transmission of electricity or natural gas or related to the capacity and use of LNG facilities, including planned or unplanned unavailability of these facilities.

2. A market participant may under its own responsibility exceptionally delay the public disclosure of inside information so as not to prejudice its legitimate interests provided that such omission is not likely to mislead the public and provided that the market participant is able to ensure the confidentiality of that information and does not make decisions relating to trading in wholesale energy products based upon that information. In such a situation the market participant shall without delay provide that information, together with a justification for the delay of the public disclosure, to the national regulatory authority having regard to Article 8(5).
