On 24 November 2022, the European Union Agency for the Cooperation of Energy Regulators (ACER) announced that it has updated its REMIT data reporting guidance.

Following extensive consultation with stakeholders launched in June 2022 that aimed to improve REMIT data reporting, ACER had published:

• The updated Transaction Reporting User Manual (TRUM) and its annexes. The amendments provided in the updated TRUM mainly focus on clarifying the reporting obligations for broker organised market places and also for market participants entering into transactions on wholesale energy markets via third party accounts.

• Updated FAQs on REMIT transaction reporting. The new FAQs provide additional guidance on specific business scenarios to better reflect the development of the trading activity on the EU wholesale energy market.

• A new version (electronic format) for the reporting of REMIT Table 1 transactions. The new version 3 of the electronic format for the reporting of REMIT Table 1 transactions implements selected changes from the public consultation on the revision of electronic formats for transaction data, fundamental data and inside reporting, as well as changes required for alignment of the electronic format with the TRUM.
