REMIT II: what Regulation (EU) 2024/1106 changed
Regulation (EU) 2024/1106 of 11 April 2024 amended REMIT. The changes most relevant to a compliance function concern how inside information is published, controls on algorithmic trading, who must register, ACER's own investigatory powers and the size of the fines national regulators can impose.

Inside information goes through platforms
Article 4(1) now requires market participants to disclose inside information through inside information platforms (IIPs), which must make it public in a way that enables prompt access, including through a website or a clear API. IIPs are authorised and supervised under a new Article 4a, and ACER was required to operate a sector-specific electronic access point for inside information by 8 May 2025.
Algorithmic trading controls
A new Article 5a requires a participant that trades algorithmically to have effective systems and risk controls: resilient trading systems with sufficient capacity, appropriate thresholds and limits, prevention of erroneous orders and of behaviour that may create or contribute to a disorderly market, compliance with the rules of the organised market place it connects to, business continuity arrangements, and testing and monitoring.
Insider trading now covers cancelling an order
Article 3(1) now states that using inside information by cancelling or amending an order, or by any other trading action, where the order was placed before the person had the information, is also insider trading.
Third-country participants and LNG
Participants established outside the EU that enter into reportable transactions had to designate a representative in a member state where they are active, and register with that state's regulator, by 8 November 2024 (Article 9). The amended definitions bring LNG facilities and LNG supply contracts explicitly into scope.
ACER can investigate
ACER may now carry out investigations itself, in cooperation with national regulators, under Articles 13a to 13c, including on-site inspections. It may do so where the acts concern wholesale energy products for delivery in at least two member states, among other grounds. A national regulator can object where it has opened or concluded an investigation on the same facts. Enforcement and penalties remain national: ACER's investigation report goes to the regulators concerned, which must say within three months what measures they will take.
Harmonised maximum fines
Article 18 now sets the minimum that national maximum fines must reach. Read the penalties page for the figures and what they mean in practice.
