Inside Information Platforms

Inside Information Platforms (IIPs) are the disclosure infrastructure of the EU REMIT framework: regulated platforms through which wholesale energy market participants must publicly disclose inside information, meaning material non-public information that could significantly affect the price of wholesale energy products. Under the REMIT recast binding on 29 April 2026, IIPs must be legally established within the European Union, a rule change that mirrors the parallel requirement for Registered Reporting Mechanisms (RRMs) and similarly targets post-Brexit UK-based operators serving EU markets.

IIPs were created to ensure market participants, predominantly utilities and large industrial energy users, can disseminate operational information (such as unplanned plant outages, pipeline interruptions, or LNG terminal shutdowns) in a standardised, timely, and accessible way. ACER oversees the registration and conduct of IIPs and can impose sanctions for non-disclosure or delayed disclosure. The Hammerfest LNG maintenance announced by Equinor is an example of the class of inside information that would typically be routed through an IIP for disclosure to the market.

The recast REMIT Delegated Regulation introduces more granular data quality and format requirements for IIPs, alongside the EU-establishment rule. ACER's consultation running to 12 June 2026 includes the IIP disclosure format specifications. As with RRMs, the compliance paradox is acute: IIPs are legally required to meet new standards from 29 April while the authoritative guidance on those standards is not finalised until June.
