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 requ​irements the 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.​

The ENTSOs' Cost-Benefit Analysis (CBA) methodologies should allow a neutral comparison between the costs of infrastructure projects with their expected benefits, in order to inform decision-makers. The CBA methodologies are useful tools for assessing the projects' merits, and therefore guiding the PCIs selection process first; and later the NRAs to take decisions on investment requests and cross-border cost allocation.

The ENTSOs have also presented an interlinked electricity and gas market and network model which should be incorporated as a future part of the CBA methodologies. A truly interlinked model will allow to study the electricity and gas energy system and network development options in a holistic way and capture the interdependencies between both sectors, leading to a more efficient network planning. The implementation of an ambitious interlinked model has gained momentum given that energy sector integration ranks high in the European agenda.​

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.​

The projects of common Interest naturally contribute to enhance the security of the European gas supply. The degree of this contribution is assessed with the help of the cost-benefit analysis methodology. 

Under the European regulation on security of gas supply, ACER is mandated to decide on CBCA reverse flow projects, to issue Opinions on exemption requests and on the elements of coordinated decisions taken by national authorities, as well as to participate in the Gas Coordination Group. 

In its opinions on the cost-benefit methodology for gas​, ACER advises on how to improve specific issues connected with security of supply.

To better identify the benefits of a stable gas supply, ACER has carried out a dedicated study on the cost of disrupted gas supply (CoDG). 

​​​​The study provides findings and suggestions for establishing a baseline of negative impact against which the merits of a project or “soft measure" can be assessed.

ACER is mandated to monitor the short-term gas supply outlooks published by ENTSOG for both winter and summer periods.

The summer outlook examines the potential evolution of the gas supply as well as the ability of the gas infrastructures to meet the demand, exports, and the storage injection needs during the summer.

The winter outlook assesses the storage levels before the winter season begins and uses simulations to assess the flexibility of gas infrastructure to dispatch gas supply to meet demand during the winter.

Gas storages play an important role in the European gas system as they supply up to 25-30% of the total gas consumed in the Union during winter. The energy crisis which followed Russia’s invasion of Ukraine in February 2022 underscored the importance of having adequately filled gas storages across Europe to enhance the preparedness for potential gas supply disruptions.

ACER, based on information provided by NRAs, periodically reviews and reports on national gas storage regulations.
