Data reporting to ACER

Pursuant to Article 8(1) REMIT, market participants, or a person or authority listed for this purpose or acting on their behalf, must provide ACER with a record of wholesale energy market transactions, including orders to trade. The EU Commission has defined data reporting pursuant to Article 8(2) and (6) REMIT in greater detail in Implementing Regulation 1348/2014.

Pursuant to Article 12(2) Implementing Regulation 1348/2014, the following data must be reported from 7 October 2015:

  • ENTSO-G reports fundamental data on gas to ACER on behalf of the market participants. Information is submitted via an EU-wide central platform.
  • ENTSO-E reports fundamental data on electricity to ACER on behalf of the market participants. Information is reported via a central information transparency platform.
  • The market participants report details of contracts on wholesale energy products executed at organised market places including matched and unmatched orders to ACER through the organised market place concerned, or through trade matching or trade reporting systems.

Furthermore, the following data have to be reported from 7 April 2016:

  • The TSO or a third party acting on its behalf reports contracts relating to the transportation of electricity or natural gas in the Union between two or more locations or bidding zones concluded as a result of an explicit allocation of primary capacity by or on behalf of the TSO, specifying physical or financial capacity rights or obligations.
  • The market participants or third parties acting on their behalf report to ACER details of contracts on wholesale energy products in relation to the supply or transportation of electricity or natural gas in the Union, concluded outside an organised market. In case of explicit allocation of primary capacity, contracts relating to the transportation of electricity and natural gas are, as mentioned in the item above, reported by the TSO or a third party acting on its behalf.
  • The TSO or third party acting on its behalf reports final nominations between bidding zones to ACER and, at their request, to the national regulatory authorities.
  • The TSO or third party acting on its behalf reports day-ahead nominations and final re-nominations of booked capacities to ACER and, at their request, to the national regulatory authorities.
  • The LNG system operators report information on the capacity, send-out, inventory, planned and unplanned unavailability announcements of the LNG facility to ACER and, at their request, to the national regulatory authorities.
  • The market participants or LNG system operators on their behalf report for every LNG facility information in relation to unloading and reloading of cargos as well as on planned uploading or reloading at the LNG facility to ACER and, at their request, to the national regulatory authorities.
  • The storage system operators report to ACER and, at their request, to the national regulatory authorities for each storage facility or, where facilities are operated in groups, for each group of storage facilities, information on the capacity, amount of gas in stock, injections and outflows as well as planned and unplanned unavailability announcements of the storage facility through a joint platform.
  • Market participants or storage system operators on their behalf report to ACER and, at their request, to the national regulatory authorities the amount of gas the market participant has stored at the end of the gas day.
  • The market participants report details of wholesale energy products relating to the transportation of electricity or natural gas in the Union executed at organised market places including matched and unmatched orders to ACER through the organised market place concerned, or through trade matching or trade reporting systems.

The details regarding the reportable contracts including orders to trade are defined in the Annex to Implementing Regulation 1348/2014. For a detailed explanation of the specifics, see the Transaction Reporting User Manual (TRUM), which is drawn up by ACER in cooperation with all relevant parties. The TRUM focuses on providing a general description of the reportable details of energy wholesale products. The technical and organisational requirements that market participants or third parties acting on their behalf must fulfil are discussed in the Requirements for Registered Reporting Mechanisms (RRMs). Parties seeking to report data must carry out an RRM registration procedure with ACER. ACER checks pursuant to Article 11 Implementing Regulation 1348/2014 whether the reporting parties abide the requirements listed in the RRM document. If the requirements are fulfilled, ACER registers the reporting parties as RRM, upon which they can report the respective data. The RRM procedure seeks to ensure secure, confidential and comprehensive data submission to ACER.
