REMIT, the Regulation on Wholesale Energy Market Integrity and Transparency, is the EU’s dedicated regime for policing abuse in wholesale electricity and natural gas markets. It prohibits insider dealing and market manipulation, and it requires market participants to report their wholesale energy transactions and orders to ACER, the EU Agency for the Cooperation of Energy Regulators. The 2024 revision, commonly called REMIT II, expanded its scope, strengthened ACER’s enforcement powers, and clarified how the regime overlaps with EMIR’s derivatives rules.

If you are new to the underlying market structure, our guide on how commodity trading works covers the basics this article assumes.

What is REMIT and who does it cover?#

REMIT is the EU regulation that entered into force in 2011 to police abuse in wholesale electricity and natural gas markets, filling a gap left by financial market rules that often missed physically settled power and gas trades. It covers “market participants”: anyone, including persons taking trading decisions on behalf of undertakings, who enters into transactions or orders to trade in wholesale energy products. Utilities, industrial consumers, producers, and purely physical traders are all in scope, as are non EU firms trading into European markets.

Financial markets had MiFID’s market abuse framework, but physically settled power and gas trades often fell outside it. REMIT closed that gap with two prohibitions and one reporting pillar.

The definition deliberately captures purely physical players, such as utilities, industrial consumers, producers, and traders, who would not otherwise be regulated as financial firms. A Swiss or US trader executing a deal on a European power exchange or with an EU counterparty can be within scope.

Wholesale energy products cover electricity and natural gas contracts and derivatives, whether traded on organized venues or over the counter. REMIT II extended the definition to include energy related products such as certain freight and LNG contracts when they affect EU energy prices, and it brought organized market places, including some platforms previously outside the perimeter, inside the regime.

What are REMIT’s two core prohibitions?#

REMIT contains two substantive prohibitions, insider dealing and market manipulation, both framed in terms very close to the EU Market Abuse Regulation, which governs financial instruments. Insider dealing concerns the use of non public information about physical energy assets, while manipulation concerns creating prices detached from genuine supply and demand. Both apply to market participants trading wholesale energy products, whether on venues or over the counter.

Insider trading#

Insider dealing under REMIT means using inside information in wholesale energy markets unless the use is lawful. Inside information here has a sector specific flavor: it includes precise information about the capacity, actual or planned, of generation, consumption, transmission, or storage facilities, and about the physical status of transporters, which is not publicly available and which, if made public, would be likely to move prices significantly.

This is broader than many traders expect. A planned outage at a nuclear plant, an interconnector constraint, a storage injection schedule, or an LNG cargo diversion can all constitute inside information. Crucially, REMIT II strengthened the requirement that market participants disclose inside information in a timely and effective manner, subject to legitimate commercial exceptions, unless the information is already public through mandatory disclosure under other rules.

Market manipulation#

REMIT prohibits market manipulation, attempted manipulation, and transactions based on false or misleading information. The manipulation definition covers:

  • Transactions giving false or misleading signals about supply, demand, or prices
  • Securing a price at an artificial level through a fictitious device
  • Transactions employing fictitious devices or deceptive contrivances
  • Dissemination of false or misleading information, including through rumor trading
  • Transactions that are legitimate in isolation but become manipulative when part of a scheme

The “artificial price” concept is the heart of most enforcement cases. A transaction is not manipulative merely because it moves the market; it is manipulative if it creates a price that does not reflect genuine supply and demand forces. This distinction matters enormously in energy, where legitimate physical operations, such as ramping a plant, storing gas, or curtailing load, routinely affect prices.

How does REMIT transaction reporting work?#

REMIT’s third pillar is data. Market participants must report wholesale energy transactions, including orders, to ACER, either directly to ACER’s ARIS system or via a registered reporting mechanism (RRM), a third party service provider. The data feeds ACER’s surveillance of EU wide markets, since manipulation often spans borders and national regulators see only fragments.

Key features of the reporting regime:

  • Scope: transactions and orders in wholesale energy products, both executed and unexecuted where required
  • Route: direct reporting to ACER’s ARIS system, or via a registered reporting mechanism (RRM), a third party service provider
  • Timing: standard deadlines apply, with near real time reporting for trades on organized venues and end of day reporting for OTC trades
  • Counterparty identification: standardized codes, such as LEIs and ACER codes, identify participants
  • Data quality: firms are accountable for accuracy, completeness, and timeliness, and resubmissions are a normal part of life

REMIT II added reporting obligations for organized market places and for the European Networks of Transmission System Operators (ENTSOs), and it expanded the data ACER can demand. In practice, most mid sized and larger participants outsource reporting to RRMs but retain legal responsibility for the data, so internal validation controls remain essential.

Which energy trading behaviors are permitted versus prohibited?#

Regulatory guidance describes REMIT’s prohibitions abstractly, but practitioners need concrete lines. The examples below separate permitted physical optimization from reportable or prohibited conduct. They are illustrative, based on the mechanics of the rules rather than any specific enforcement case.

Physical optimization versus manipulation#

A gas trader with storage capacity injects gas in summer and withdraws in winter, profiting from the seasonal spread. This is legitimate: the price impact reflects genuine supply and demand.

The same trader holds a large short position in a monthly gas future, then withdraws from storage in a way designed purely to depress the spot price at a settlement point, without any commercial rationale for the timing. If the withdrawal pattern is economically inexplicable except as a price play, regulators can treat it as manipulation. The tell is the absence of a defensible commercial rationale, not the price impact itself.

Information handling#

A power company knows a generating unit will trip offline next week. Trading on that knowledge before public disclosure is insider dealing under REMIT. However, if the outage must be disclosed under transparency rules or the firm’s own disclosure policy, and the information is made public promptly, trading after disclosure is fine.

A trader hears a rumor that an LNG terminal will shut down, verifies nothing, and spreads the rumor to move TTF prices. That is dissemination based manipulation, regardless of whether the rumor turns out true. Our article on how the TTF gas price works explains why terminal outages can move European benchmark prices so sharply.

Cross market conduct#

A firm with a large position in EU carbon allowances takes a position in power futures designed to push the power price, and thus the clean spark spread, in a favorable direction. Interference in one market to benefit a position in another is squarely within REMIT’s manipulation definition, and carbon prices interact with power prices in ways regulators model closely. See our overview of how the EU ETS carbon market works for the linkage.

Bona fide hedging versus artificial prices#

An industrial consumer hedging forecast load with monthly power futures is legitimate, even in size, because the trades reflect genuine physical exposure. Layering orders on a power exchange, entering large orders with no intention of execution, to create a false impression of demand, is prohibited, and spoofing of this kind is one of the clearest manipulation categories.

The table below summarizes the boundary:

ConductTypical factsREMIT status
Seasonal storage arbitrageInjection and withdrawal driven by commercial spreadPermitted
Timed withdrawal to hit a settlement index with no commercial rationalePrice impact is the only plausible motiveManipulation
Trading after lawful public disclosure of an outageInformation no longer insidePermitted
Trading on a known but undisclosed outageInside information usedInsider dealing
Spreading an unverified outage rumor to move pricesFalse or misleading signalManipulation
Large but genuine load hedge in power futuresReflects real exposurePermitted
Order layering on an exchangeFictitious demand signalManipulation

How does REMIT interact with EMIR?#

Energy derivatives live under two regimes at once. REMIT cares about market integrity: who traded what, and whether conduct was abusive. EMIR cares about derivatives infrastructure: reporting to trade repositories, central clearing for standard contracts, and risk mitigation techniques for uncleared trades. An OTC power swap can be both a REMIT wholesale energy product and an EMIR derivative, triggering duties under both regimes.

The practical consequences:

  • Dual reporting: an OTC power swap that is a REMIT wholesale energy product and an EMIR derivative must be reported both to ACER and to an EMIR trade repository. REMIT II streamlined this so that, where a transaction is already reported under EMIR and the data satisfies REMIT requirements, it need not be reported twice, but firms must verify their EMIR data actually meets REMIT’s field level requirements before relying on this.
  • Different identifiers and schemas: ACER’s transaction reporting market model and EMIR’s ISO based schemas differ, so field mapping is a real project, not a checkbox.
  • Different triggers: EMIR obligations follow the derivative classification; REMIT follows the wholesale energy product definition, which now reaches further, including some physically settled contracts EMIR never touches.

For a fuller comparison of the financial market regimes that sit alongside REMIT, see EMIR vs MiFID II: what energy traders must know. Firms trading paper alongside physical books should also read our breakdown of physical vs paper trading differences, since REMIT’s perimeter cuts across both.

What changed in the 2024 REMIT II revision?#

The recast REMIT regulation, adopted in 2024 and known as REMIT II, expanded the product scope, strengthened ACER’s investigative and enforcement role, and extended reporting obligations. It was driven by the 2022 energy crisis, when volatile prices and alleged manipulation raised surveillance questions. The main changes:

  1. Broader product scope: wholesale energy products now include energy related products such as LNG freight contracts when they can affect EU energy prices, and organized market places are explicitly covered.
  2. Stronger ACER role: ACER gained clearer investigative powers, the ability to request data from market participants, and a central position in cross border enforcement, with national regulators (NRAs) handling most day to day supervision.
  3. Extended reporting: organized market places and ENTSOs report directly, and the data model was expanded to improve surveillance analytics.
  4. Third country reach: the EU can require operators outside the EU whose conduct affects EU markets to cooperate, and equivalence based arrangements can extend REMIT requirements abroad.
  5. Coordination with financial regulators: the revision tightened the interface with MiFID and EMIR authorities so that dual regulated firms face coherent, not duplicated, demands.

Implementation is phased, with reporting and organizational requirements coming into force over the years following adoption, so firms should track the applicable dates rather than assuming immediate effect.

What compliance architecture do REMIT market participants need?#

A defensible REMIT posture has five components: surveillance of trading behavior, controls over inside information and disclosure, documentation of commercial rationale for physical operations, reporting controls, and trader training with escalation channels. Swiss and other non EU firms trading into European markets should note that REMIT applies extraterritorially when conduct affects EU wholesale markets.

The five components:

  • Surveillance: automated monitoring of trading against benchmarks, flagging unusual volumes, price impact, and order to trade ratios, especially around index settlement windows
  • Information barriers and disclosure: policies identifying inside information, controlling who can trade, and ensuring timely public disclosure of outage and capacity information
  • Documentation of commercial rationale: for physical operations that move prices, contemporaneous records of why the operation was scheduled as it was, since post hoc explanations carry little weight
  • Reporting controls: validation of RRM output, error handling, and reconciliation between REMIT, EMIR, and internal books
  • Training and escalation: traders must understand that “everyone does this” is not a defense, and compliance needs a channel to pause trades when a flag is raised

Firms in Geneva should also review FinfraG and Swiss commodity trading rules to understand how home state and EU regimes stack, and our piece on why Geneva became a global commodity trading hub explains the market context that makes this dual regulation a daily reality for Geneva based energy desks.

Key Takeaways#

  • REMIT prohibits insider trading and manipulation in EU wholesale electricity and gas markets, and it applies to purely physical players, not just financial firms.
  • Inside information in energy includes precise capacity, outage, storage, and infrastructure status information, and REMIT II tightened the duty to disclose it.
  • Manipulation turns on whether a price is artificial, meaning detached from genuine supply and demand, not merely on whether prices moved.
  • Transactions and orders must be reported to ACER, directly or via an RRM, with the firm retaining responsibility for data quality.
  • Energy derivatives are typically caught by both REMIT and EMIR; REMIT II reduced double reporting but only where EMIR data fully satisfies REMIT requirements.
  • The 2024 revision broadened scope to LNG and freight related products, empowered ACER, and phased in new reporting duties, so firms should verify applicable dates.
  • The practical dividing line is commercial rationale: legitimate physical optimization is defensible, while operations explicable only as price plays are not.

Key concepts

Frequently asked questions

What does REMIT prohibit?

REMIT prohibits insider trading and market manipulation in wholesale energy markets, including electricity and natural gas traded in the EU. It applies to physical and financial trades alike, whether or not the participant is otherwise regulated. It also imposes transaction reporting duties on market participants.

Who must report transactions under REMIT?

Market participants entering into wholesale energy products, including orders to trade, must report those transactions to ACER, the EU Agency for the Cooperation of Energy Regulators. Since the 2024 revision, organized market places and the ENTSOs also carry data reporting obligations. Reporting is typically done directly to ACER or via a registered reporting mechanism.

How does REMIT interact with EMIR?

REMIT covers wholesale energy market integrity regardless of instrument type, while EMIR governs derivatives reporting, clearing, and risk mitigation. Energy derivatives are generally reported under both regimes, so firms must reconcile REMIT and EMIR reporting flows. REMIT II clarified overlaps so that transactions already reported under EMIR are not double-reported under REMIT.

What changed in the 2024 REMIT revision?

The 2024 revision, often called REMIT II, expanded the definition of wholesale energy products, extended rules to organized market places and energy related derivatives, and strengthened ACER's supervisory and enforcement powers. It also tightened data collection and introduced clearer coordination between ACER and financial regulators.
