Background

REMIT, the Regulation on Wholesale Energy Market Integrity and Transparency, is the EU's legal framework prohibiting insider trading and market manipulation in wholesale electricity, gas and LNG markets, adopted in 2011. It requires participants to report transactions and disclose inside information via Registered Reporting Mechanisms and Inside Information Platforms, and is enforced jointly by ACER and national energy regulators across every EU member state.

The regulation was substantially revised in 2019, known as REMIT II, and again in 2024, when amendments gave ACER direct cross-border investigatory and sanctioning powers for the first time; before then it could only refer suspected breaches to national regulators to act on. A Gas Market Task Force review has separately recommended aligning REMIT with MiFID to consolidate reporting for desks trading across multiple commodities.

Key Issues
Energy market enforcement

Its cross-border enforcement powers switch on

REMIT's recast implementing instruments entered force on 29 April 2026 with no transition relief, cutting the transaction-reporting window from one month to 14 days and adding a position-level exposure obligation. National regulators filed 204 suspicious transaction and order reports in 2025, double the 2024 figure, evidence ACER has cited to justify the tougher regime.

ACER's expanded cross-border investigatory and sanctioning powers activate in the second half of 2026, the first time it will sanction directly rather than refer cases to national regulators, though the final reporting rulebook is deferred to October. A transaction-reporting annex consultation covering energy derivatives opened 16 July and closes 11 September.

Common Questions

Reference

What is the difference between REMIT and MiFID for energy trading?
REMIT regulates physical wholesale energy markets (gas and electricity spot) and inside information. MiFID II covers financial instruments including energy derivatives. Desks running both physical and financial legs face parallel reporting obligations under each regime; the GMTF recommended legislative alignment to merge them.Source: SWD(2026)147, 2 June 2026
Does REMIT apply to LNG trading and non-EU companies?
Yes. REMIT covers LNG spot and derivative markets alongside electricity and gas. The 2026 recast removed all grandfather clauses for non-EU reporting intermediaries, meaning firms outside the EU regulatory perimeter face immediate compliance requirements with no phase-in.Source: ACER REMIT 2.0 compliance documents, April 2026
Can energy companies outside the EU be fined under REMIT?
Non-EU reporting intermediaries receive no grandfather clause under the April 2026 recast; they face full compliance requirements with no phase-in under ACER's direct sanctioning authority.Source: REMIT 2024 amendments
What new powers does ACER have under REMIT since 2024?
The 2024 REMIT amendments gave ACER direct investigatory and sanctioning authority, the most significant expansion since the 2019 REMIT II update. ACER can now directly investigate and fine market participants rather than only coordinating national regulator actions.Source: ACER / European Commission
What is REMIT and how does it regulate European energy trading?
REMIT is the EU regulation banning insider trading and market manipulation in wholesale energy markets. It covers electricity, gas, and LNG spot and derivatives, and requires market participants to report trades and inside information.
Does REMIT apply to LNG trading?
Yes. REMIT covers wholesale LNG markets including spot transactions and derivatives. ACER updated its LNG price assessment methodology in April 2026 and convened a dedicated Expert Group, reflecting growing LNG market significance after the Hormuz disruption.Source: ACER

Recently resolved

What is the REMIT compliance paradox in 2026?
The recast REMIT rules bound market participants from 29 April 2026, while ACER's consultation on transaction-reporting guidelines remained open until 12 June. The final guideline is now deferred to October 2026, leaving roughly six months of binding obligation against interim text.Source: ACER
What changed in REMIT in April 2026?
ACER confirmed on 22 April 2026 that the recast REMIT rules enter force on 29 April with no transition relief. Contracts on 28 April use the old one-month reporting window; identical contracts on 29 April use the new 14-day window, with no grace period.Source: ACER
Why is REMIT being aligned with MiFID?
The Gas Market Task Force recommended legislative alignment in SWD(2026)147 (2 June 2026) because cross-commodity desks running physical gas and financial derivatives face duplicated reporting obligations under two separate regimes. Alignment would consolidate them and ADD algorithmic-trading monitoring.Source: SWD(2026)147, 2 June 2026
When will ACER use its new direct enforcement powers under REMIT?
ACER's expanded cross-border investigatory powers under the 2024 REMIT revision are due to activate in H2 2026. The annual ACER/EC REMIT workshop on 11 June 2026 is the first formal enforcement venue under the new framework.Source: Lowdown European Energy Markets
Why did energy market suspicious transaction reports double in 2025?
ACER's 8 May report showed 204 STORs filed by national regulators in 2025, double 2024 levels, attributed to TTF volatility driven by Hormuz disruption and improved national surveillance.Source: ACER enforcement report
What was the first REMIT 2.0 deadline in 2026?
The T+10 transaction reporting Deadline landed on 12 May 2026, two weeks after the recast framework entered force on 29 April.Source: ACER
How many suspicious transaction reports were filed under REMIT in 2025?
204 STORs (Suspicious Transaction and Order Reports) were filed by national regulators in 2025, double the 2024 figure, according to ACER's enforcement report published May 2026.Source: ACER REMIT Quarterly 44, May 2026
