The TRUM (Trade Reporting User Manual) is the document published and periodically updated by the European Agency for the Cooperation of Energy Regulators (ACER), which serves as a key operational tool for transactions and orders reporting under the REMIT Regulation (encompassing power and gas trading processes).



REMIT Implementing Act

Article 10(3)


The Agency shall after consulting relevant parties establish procedures, standards and electronic formats based on established industry standards for reporting of information referred to in Articles 6, 8 and 9. The Agency shall consult relevant parties on material updates of the referred procedures, standards and electronic formats.


The legal base for TRUM's issuance is Article 10(3) of the Commission Implementing Regulation No 1348/2014 of 17 December 2014 on data reporting implementing Article 8(2) and Article 8(6) of Regulation (EU) No 1227/2011 of the European Parliament and of the Council on wholesale energy market integrity and transparency (REMIT Implementing Act).


TRUM forms an integral part of the REMIT Reporting User Package adopted by ACER.


The final TRUM's release has been preceded by the following procedure:


- On 30 October 2013, the European Commission presented a draft of the REMIT Implementing Act to be adopted pursuant to Article 8 of REMIT.


- The draft for REMIT Implementing Act provided that the ACER should explain the details of the reportable information in a user manual.


- On 27 March 2014, the ACER launched a public consultation on the draft TRUM, based on the draft REMIT Implementing Act presented by the European Commission in October 2013. The public  consultation lasted until 5 May 2014.


- The second public consultation on the TRUM was based on the draft Implementing Act published by the European Commission in July 2014, and took into account the input received during the first consultation in 2014. It included a consultation on the List of Standard Contracts. The second public consultation lasted until 2 September 2014. 


The TRUM was published for the first time on 8 January 2015 upon entry into force of REMIT Implementing Act.


On 30 September 2015 ACER has updated the TRUM and released the version 2.0, and on 31 March 2016 version 2.1 has been published. Subsequent updates are published quite often.


Minutes of 16 November 2021 from 2021 Joint roundtable meeting od ACER with AEMPs, OMPs and RRMs (Reference: RT-AEMP-OMP-RRM-2021)

The review of TRUM v5.0 and its Annex II was focused on clarifying the guidance for the reporting of contracts referred to the transportation of natural gas, reportable via the electronic format corresponding to Table 4 of REMIT Implementing Regulation. Such clarifications had been triggered by the outcome of ACER’s data quality analysis on Table 4 data. ACER presented some specific amendments to the main text of TRUM, in particular those in the introductory Section 3.2.1 on supply contracts and Section 3.2.1 on transportation contracts, as well as some amendments of Section 7, dedicated to the guidance on Table 4 data fields. Regarding Annex II v4.1, ACER presented two new examples on non-standard contracts for the supply of natural gas via LNG cargo (29.01 and 30.01) and three new examples on how to report lifecycle events of contracts referring to the transportation of natural gas. The stakeholders provided some preliminary feedback to some specific questions raised by ACER on the field descriptions in Table 4. Regarding Data Field (2) Organized market place identification, an attendee commented that a booking platform itself might not be an entity but a system. If ACER needs the EIC of the booking platforms for the population of Data Field (2) in Table 4, then the EIC should be “V” type (for IT-systems). If an “X” type code is expected, it should be specified that the EIC of the operator of the booking platform is required. ACER welcomed this comment and took note of it.
As for the future projects, ACER indicated the intention to consult in 2022 on the XML version of the Annex II of TRUM, as well as on a revised version of the transaction reporting guidance focused on trading activity on brokers’ platforms, triggered by the outcome of ongoing data quality analysis.
