​​​​Under REMIT, information is considered ‘inside information’ if it is:

• precise in nature;
• not yet public;
• directly or indirectly related to wholesale energy products; and
• likely to significantly affect wholesale energy prices if made public.

Market participants are obliged to disclose inside information and should always inform ACER via web feeds.

Inside information should be disclosed promptly and in a way that enables broad public access. This is why the disclosure of inside information effectively happens through central platforms that aggregate 'urgent messages' from market participants (i.e. inside information platforms (IIPs)). In 2020, ACER started registering IIPs as Regulated Information Services (RISs).

To help market participants and NRAs apply REMIT consistently, ACER provides a range of guidance and reference materials, including:

• ACER REMIT guidance

  ACER regularly publishes non-binding guidance for NRAs (together with guidance notes), providing in-depth information on specific types of market abusive practices. This helps ensure effective coordination and consistent application of REMIT. ACER also provides guidance for market participants on how to report trading data under REMIT and comply with data reporting obligations.

• Guidelines and recommendations

  ACER may issue guidelines and recommendations addressed to all NRAs or market participants to support consistent and effective supervisory practices and ensure uniform application of the EU law. These documents are subject to public consultations.

• REMIT Q&As

  ACER also publishes Q&As documents summarising frequently asked questions about REMIT. Q&As provide practical guidance to stakeholders, but do not constitute a binding legal interpretation.

Where to find these documents?

All guidance, Q&As and related documents are available on REMIT Documents and REMIT Knowledge Base, which offer an easy way to search and consult relevant materials.

Stakeholders can submit any REMIT-related questions that are not addressed in the existing documentation via the online REMIT Query Form.

Registered reporting mechanisms (RRMs) report trade and/or fundamental data directly to ACER under REMIT. 

RRMs must comply with the technical and organisational requirements for the reporting of data defined in the RRM requirements document, and are registered by ACER to provide the service of reporting.

The process on how to register an RRM is described in the RRM require​ments.

Before initiating the registration process, please carefully read all the information to understand the requirements RRMs have to fulfil.

Market Participants are obliged to notify the Agency and the relevant National Regulatory Authority (NRA) when applying certain exemptions of REMIT, and should use the Notification platform application​ to fulfil their notification obligations on the delayed disclosure of inside information or the coverage of an immediate physical loss resulting from unplanned outages. 

Persons professionally arranging transactions in wholesale energy products, (like organised market places and trade-matching systems) have the legal obligation to monitor their operating platforms to identify market abuse behaviours. In case of any reasonable suspicion, the national regulatory authority should be informed with no delay.​

EU energy market transparency and integrity benefit everyone. 

This section provides direct access to the platforms for:

• notifying potential REMIT breaches and suspicious behaviour via ACER’s REMIT Notification Platform;
• notifying the use of REMIT exemptions via ACER’s REMIT Notification Platform;
• submitting questions on REMIT;
• registering as registered reporting mechanism (RRM) or inside information platform (IIP).

Under the Trans-European Energy Infrastructure (TEN-E) Regulation, the ENTSOs’ Cost-Benefit Analysis (CBA) methodologies aim to ensure a transparent and neutral comparison between the costs of infrastructure projects and their expected benefits. They support the selection of Projects of Common Interest (PCIs) and inform national regulatory authorities’ decisions on investment requests and cross-border cost allocation.

ENTSO-E and ENTSOG are also required to establish and progressively implement a consistent and integrated model as part of their system needs assessment and CBA methodologies. This integrated model for electricity, gas and hydrogen network planning should support both cross-sectoral infrastructure needs assessment at system level and project-specific CBAs. By improving consistency of assumptions and methodologies and better capturing interactions between sectors, it helps contribute to more coherent and cost-effective EU network planning.

ACER provides Opinions on each draft cost-benefit analysis methodologies developed by the ENTSOs, as well as the interlinked model, and may request the process for CBA updates.​​​​

ACER provides a cooperation framework for NRAs to establish and publish a set of indicators and corresponding reference values for the comparison of unit investment costs for projects of gas and electricity infrastructure, which could be used in CBA analysis.​
