Inside Information Platforms
REMIT-regulated platforms for public disclosure of inside information by wholesale energy market participants.
Since the recast REMIT reporting rules took force on 29 April 2026, Inside Information Platforms serving EU wholesale energy markets must be legally established within the EU, which shuts out operators based elsewhere, including in the UK.

European Energy MarketsBackground
Inside Information Platforms (IIPs) are the disclosure channels of the EU's REMIT market-Integrity regime. Wholesale energy market participants use them to publish inside information: non-public facts that could significantly move wholesale gas or power prices, such as unplanned plant outages, pipeline interruptions or LNG terminal shutdowns.
The platforms exist so that such information reaches the whole market at once and in a standard format, rather than reaching a few traders first. ACER, the EU Agency for the Cooperation of Energy Regulators, oversees the regime, and national regulators can sanction late or missing disclosure.
The recast REMIT framework, in force since 29 April 2026, requires IIPs to be legally established within the EU. ACER published four compliance documents the same day, including a new exposure-reporting template for market participants.
Platforms must now be EU-established
On 9 April 2026 ACER published two new REMIT instruments, a recast data-reporting framework and a companion regulation, both entering force on 29 April. For Inside Information Platforms the recast adds an establishment test: from 29 April a platform must be legally established within the EU to carry disclosures for its wholesale markets.
The compliance window after 29 April was short. ACER opened a consultation on transaction-reporting guidelines on 16 April, running to 12 June, so platforms and the firms that publish through them worked under binding rules for 44 days while guidance remained open. ACER issued four further compliance documents on 29 April as the rules took effect.
