Understanding the Purpose Behind REMIT II
Originally introduced to prevent insider trading and market manipulation in European wholesale energy markets, REMIT has played a critical role in strengthening trust and transparency within the sector.However, modern trading environments now generate enormous volumes of real-time market data, making traditional compliance processes increasingly difficult to manage manually. REMIT II aims to close these gaps by enhancing regulatory powers, improving reporting standards, and expanding market surveillance capabilities.Under the revised framework, organizations are expected to maintain stronger internal controls, improve transaction reporting accuracy, and ensure faster identification of suspicious trading activities.This means compliance is no longer just about meeting obligations — it is becoming a core business function directly linked to operational resilience and reputational risk.The Growing Role of Technology in Compliance
One of the biggest shifts driven by REMIT II is the increasing reliance on technology-enabled compliance systems.Across Europe, energy firms are investing in AI-powered surveillance platforms, advanced analytics, and automated reporting tools to monitor trading behavior more efficiently and reduce the risk of regulatory breaches. These technologies can identify unusual patterns, flag potential market abuse, and support compliance teams with faster, data-driven decision-making.

At the same time, regulators are also becoming more technologically advanced. With enhanced access to transaction data and cross-market monitoring capabilities, authorities are expected to identify irregularities with greater speed and precision than ever before.As a result, organizations that continue relying on fragmented or manual compliance systems may face increasing operational and regulatory challenges in the years ahead.Beyond Regulation: A Strategic Opportunity
While many organizations view REMIT II primarily through a compliance lens, forward-looking companies are treating it as an opportunity to modernize governance frameworks, strengthen market credibility, and improve long-term business resilience.The future of energy trading will depend heavily on transparency, digital transformation, and proactive risk management. Firms that adapt early will not only reduce regulatory exposure but also gain a competitive advantage in an increasingly complex market environment.As these discussions continue shaping the future of European energy markets, REMIT 2026 will bring together compliance leaders, regulators, surveillance experts, legal professionals, and technology innovators to exchange insights on the next generation of energy trading compliance.

Join the conversation at the 4th REMIT Compliance in European Energy Trading 2026 conference, where compliance leaders, regulators, energy traders, utilities, exchanges, and market surveillance experts will come together to discuss the implementation of REMIT II, evolving reporting obligations, enhanced market monitoring requirements, and best practices for strengthening transparency, regulatory compliance, and market integrity across European wholesale energy markets.

Why AI Will Redefine Energy Trading Surveillance

From reactive monitoring to proactive intelligence in energy markets

The energy trading landscape is becoming increasingly complex. With growing market volatility, cross-border transactions, algorithmic trading strategies, and expanding regulatory expectations, surveillance teams face an unprecedented challenge: how to effectively monitor vast volumes of trading activity while identifying potential market abuse in real time.Traditional surveillance systems were designed for a different era. Many rely on predefined rules, manual reviews, and retrospective investigations. While these approaches remain important, they often struggle to keep pace with today's highly dynamic trading environments.This is where Artificial Intelligence is beginning to redefine energy trading surveillance.

The Limitations of Traditional Surveillance

Conventional monitoring systems typically generate alerts based on fixed thresholds or known patterns of suspicious behavior. However, market manipulation techniques continue to evolve, making it increasingly difficult to identify emerging risks using static rules alone.Compliance teams are also dealing with growing volumes of transaction data, communication records, and market information. Reviewing this data manually can be time-consuming, resource-intensive, and prone to oversight.As regulatory expectations continue to rise, organizations are seeking smarter ways to strengthen market integrity and reduce compliance risk.How AI Is Changing the Game

AI-powered surveillance systems can analyze massive datasets in real time, identifying unusual trading patterns, behavioral anomalies, and hidden relationships that may not be immediately visible through traditional monitoring methods.Machine learning models can continuously improve by learning from historical data and adapting to changing market conditions. This allows surveillance teams to move beyond simple rule-based monitoring toward more intelligent risk detection.Rather than replacing compliance professionals, AI enhances their ability to focus on higher-risk activities and conduct more effective investigations.

Join the conversation at the 4th REMIT Compliance in European Energy Trading 2026 conference, where compliance professionals, regulators, energy traders, utilities, exchanges, and market surveillance experts will come together to explore the impact of REMIT II, the future of AI-powered market surveillance, evolving reporting obligations, and strategies for detecting market abuse, reducing false positives, and strengthening transparency and market integrity across European wholesale energy markets.

How ACER Is Shaping the Next Chapter of REMIT Compliance

As REMIT II reshapes Europe's wholesale energy markets, ACER is transforming how market participants approach surveillance, reporting, and regulatory readiness.

The European energy market has changed dramatically over the past decade. Greater renewable integration, increased cross-border trading, algorithmic trading strategies, and heightened geopolitical uncertainty have created a more complex trading environment than ever before.While these developments have improved market efficiency, they have also introduced new compliance challenges. Larger trading volumes, faster execution speeds, and increasingly sophisticated trading strategies make detecting market abuse significantly more difficult using traditional monitoring techniques.
To address these challenges, the revised REMIT framework—commonly referred to as REMIT II—strengthens the regulatory architecture governing wholesale energy markets. Although the legislation itself was adopted by the European Union, the practical implementation is being driven by the Agency for the Cooperation of Energy Regulators (ACER).

Today, ACER is not only collecting market data. It is helping define how market participants report transactions, monitor trading activity, improve data quality, and prepare for a new generation of compliance expectations.

Why ACER's Role Is Becoming More Important

Energy trading no longer takes place within isolated national markets. Electricity and gas transactions increasingly span multiple European countries, involving numerous trading venues, reporting mechanisms, and market participants.This interconnected environment requires regulators to identify suspicious behavior across borders rather than within individual jurisdictions.ACER serves as the central coordinator of this effort. By collecting transaction data, analyzing market activity, issuing technical guidance, and working closely with National Regulatory Authorities (NRAs), ACER helps create a consistent supervisory framework across the European Union.For compliance professionals, this means that regulatory oversight is becoming more coordinated, more data-driven, and increasingly reliant on technology.Key Changes Market Participants Should Understand

1. Enhanced Market Surveillance

One of the most significant developments under REMIT II is the expansion of ACER's surveillance capabilities.Rather than relying primarily on reports submitted after potential incidents occur, regulators now have greater access to market data that allows them to detect suspicious trading patterns earlier.Cross-border investigations are expected to become faster, improving regulators' ability to identify insider trading, market manipulation, and other forms of abusive market behavior.For organizations, this increases the importance of maintaining effective internal surveillance systems capable of identifying unusual trading activity before regulators do.

2. Higher Standards for Transaction Reporting

Accurate reporting has always been central to REMIT compliance, but the expectations surrounding reporting quality are continuing to evolve.Updated reporting requirements place greater emphasis on data consistency, completeness, and standardization. Even relatively small reporting errors can reduce regulators' ability to analyze trading behavior across markets.As a result, firms are increasingly reviewing their reporting processes, improving data governance frameworks, and investing in automated reporting solutions that reduce operational risk.

3. Increased Attention on Algorithmic Trading

The growth of algorithmic and automated trading has fundamentally changed how energy markets operate.While automation enables greater trading efficiency, it can also introduce new compliance risks if trading algorithms are not properly monitored.Regulators are therefore placing greater attention on algorithmic trading activities, including governance arrangements, Direct Electronic Access (DEA), and the ability of firms to explain how automated strategies operate.Organizations using automated trading systems should ensure that compliance teams, risk managers, and technology specialists work closely together to oversee these activities.

4. Greater Oversight of Reporting Infrastructure

REMIT II also strengthens oversight of Registered Reporting Mechanisms (RRMs) and Inside Information Platforms (IIPs).These platforms play a critical role in ensuring that transaction reports and inside information disclosures reach regulators accurately and efficiently.Improved supervision of these reporting channels is expected to enhance data reliability while supporting more effective market monitoring across Europe.

Compliance Is Becoming Technology-Driven
Perhaps the most significant trend emerging from REMIT II is the increasing reliance on technology-enabled compliance.Manual monitoring processes are no longer sufficient for analyzing millions of trading records, communication logs, and market events.Instead, organizations are adopting artificial intelligence, machine learning, automated reporting platforms, and advanced analytics to strengthen surveillance capabilities.These technologies allow compliance teams to identify behavioral anomalies, reduce false positives, prioritize high-risk alerts, and investigate suspicious activity more efficiently.Technology is no longer simply supporting compliance—it is becoming one of its most important foundations.

What Should Organizations Do Next?

As ACER continues refining reporting guidance and supervisory expectations, organizations should begin preparing today rather than waiting for regulatory deadlines.Practical priorities include:Reviewing transaction reporting processes for completeness and accuracy.
Assessing whether existing surveillance systems can detect emerging market abuse patterns.
Strengthening data governance and record-keeping practices.
Evaluating AI and advanced analytics solutions for compliance monitoring.
Providing ongoing training to compliance, trading, legal, and operational teams on evolving REMIT obligations.Organizations that invest early in these capabilities will be better positioned to manage regulatory expectations while improving operational resilience.

Looking Ahead
The future of REMIT compliance extends well beyond legislation. It will be shaped by how effectively organizations interpret ACER's guidance, implement stronger surveillance frameworks, and embrace technology to improve compliance outcomes.For compliance leaders, traders, legal professionals, and technology providers, the message is clear: regulatory expectations are becoming more sophisticated, and compliance strategies must evolve accordingly.As these developments continue to reshape European energy markets, REMIT 2026 will provide a valuable platform for industry experts to discuss practical implementation strategies, share best practices, and explore the technologies defining the next generation of energy market compliance.

National Regulatory Authorities (NRAs) vs. ACER: Where Enforcement Lines Fall

Understanding who does what under REMIT II—and why knowing the difference is essential for every energy market participant.

As the European wholesale energy market becomes increasingly interconnected, effective regulatory oversight has become more important than ever. The implementation of REMIT II has strengthened the European framework for preventing insider trading, market manipulation, and other forms of abusive behavior. However, one question continues to arise among market participants:Who is actually responsible for enforcing REMIT—ACER or the National Regulatory Authorities (NRAs)?The answer is both.
While ACER and the NRAs work closely together, they have distinct responsibilities. Understanding where these responsibilities begin and end is essential for compliance professionals, traders, legal teams, and reporting specialists navigating today's regulatory landscape.

The Shared Goal: Protecting Market Integrity

Both ACER and the National Regulatory Authorities share the same objective—to ensure Europe's wholesale energy markets remain transparent, competitive, and free from market abuse.Rather than operating independently, they form a coordinated supervisory network. ACER provides the European-wide perspective, while NRAs enforce the rules within their respective Member States.This collaborative model enables regulators to monitor increasingly complex cross-border energy markets while maintaining effective local enforcement.ACER: The European CoordinatorThe Agency for the Cooperation of Energy Regulators (ACER) sits at the centre of REMIT's supervisory framework.Its primary role is not to impose penalties on market participants but to collect, analyse, and interpret transaction data from across Europe. By consolidating information from multiple trading venues and reporting mechanisms, ACER can identify suspicious patterns that may not be visible within a single country.Key responsibilities of ACER include:Collecting and analysing wholesale energy transaction data.
Monitoring cross-border trading activity.
Coordinating investigations involving multiple Member States.
Issuing REMIT guidance, technical documentation, and reporting manuals.
Supervising Registered Reporting Mechanisms (RRMs) and Inside Information Platforms (IIPs).
Supporting consistency in the application of REMIT across Europe.Because ACER has access to data from across the European Union, it plays a crucial role in identifying market abuse that extends beyond national borders.National Regulatory Authorities: The Frontline Enforcers

While ACER performs market-wide monitoring, the responsibility for enforcement largely rests with each country's National Regulatory Authority.NRAs investigate suspected breaches of REMIT within their jurisdictions and have the authority to take enforcement action where necessary.Their responsibilities typically include:Investigating suspected market manipulation or insider trading.
Conducting inspections and requesting information from market participants.
Imposing administrative penalties or sanctions where permitted under national law.
Monitoring compliance with reporting and disclosure obligations.
Working directly with companies operating in their domestic energy markets.For energy companies, the NRA is often the regulator they interact with most frequently during compliance reviews or investigations.How ACER and NRAs Work Together

One of REMIT II's most significant developments is the strengthening of cooperation between ACER and NRAs.If ACER detects unusual trading behavior through its market surveillance systems, it can share intelligence with the relevant NRA. The NRA then assesses the evidence, conducts further investigations if required, and determines whether enforcement action should be taken.This coordinated approach enables regulators to investigate cases involving multiple countries more efficiently while reducing the risk that suspicious activity goes unnoticed.The result is a more integrated and effective enforcement framework across European energy markets.What This Means for Market Participants

For compliance teams, understanding the division of responsibilities is more than an academic exercise—it directly influences how organizations prepare for regulatory oversight.Companies should recognize that although they may primarily engage with their domestic NRA, their reported transaction data contributes to a broader European surveillance system managed by ACER.This means firms should focus on:Maintaining accurate and complete transaction reporting.
Strengthening internal market surveillance capabilities.
Establishing clear governance over trading activities.
Ensuring robust record-keeping and audit trails.
Staying up to date with ACER's guidance, FAQs, and reporting manuals, while also monitoring their NRA's national requirements.Compliance is no longer limited to meeting local obligations; organizations must be prepared for scrutiny within a coordinated European regulatory framework.Looking Ahead

As REMIT II continues to reshape energy market regulation, the relationship between ACER and the National Regulatory Authorities will become even more important. ACER provides the strategic oversight, cross-border intelligence, and technical guidance that support a harmonized European market, while NRAs remain responsible for investigating breaches and enforcing the rules at the national level.For market participants, success will depend on understanding both perspectives. Organizations that align their compliance programmes with ACER's evolving guidance while maintaining strong relationships with their domestic regulator will be better positioned to navigate regulatory change, reduce compliance risk, and contribute to a more transparent and resilient European energy market.These developments continue to reshape European energy markets, REMIT 2026 will provide a valuable platform for industry experts to discuss practical implementation strategies, share best practices, and explore the technologies defining the next generation of energy market compliance.
