Inside information

Publication of inside information

Inside information is any precise unpublished piece of information which relates, directly or indirectly, to a wholesale product and which, if it were made public, would be likely to significantly affect the prices of those wholesale products.

When a piece of inside information is available to a market participant, they are obliged to publish them fully and in due time on their website and/or the centralised website prior to the realisation of a transaction related to the information.

If a piece of inside information is disclosed unintentionally, a market participant, i.e. the person engaged by the market participant to act on their account is obliged to publish that piece of information fully without delay in line with REMIT Rules.

Inside information which are published in particular are pieces of information related to capacity and the use of electricity and natural gas facilities for production, storage and consumption, electricity i.e. natural gas transmission system, natural gas storage capacity and use, natural gas regasification terminal, including data on planned or unplanned unavailability of all energy systems, i.e. facilities. The information about key infrastructure and information on the assessment of demand for improvement of its protection are not published.

Delay of inside information publication

The publication of inside information may be delayed by a market participant only if the publication would endanger their legitimate interest, if the delay of publication does not mislead the public, if they can provide the confidentiality of that piece of information and if decisions related to wholesale market trade are not made based on that decision.

When all conditions for the delay of inside information publication are met, market participant reports this piece of information with the Agency on the Template REMIT R-3 indicating reasons for the delay of its publication.

In this case, the transaction is reported to the Agency within Template REMIT R-6.
