On 18 December 2024, the EU Agency for the Cooperation of Energy Regulators (ACER) published updated versions of the following documents in light of the amendments that were made to the Regulation on wholesale energy market integrity and transparency by Regulation (EU) 2024/1106 (revised REMIT):

• Transaction Reporting User Manual (TRUM) and its Annexes. The amendments mainly focus on clarifying the definition of Organised Marketplaces (OMPs), outlining their criteria and characteristics. This update aligns TRUM with the revised REMIT and aims to create a consistent understanding to help market participants, regulators, and other stakeholders identify and assess OMPs.
• Guidance on reporting LNG market data. The update aligns the legal references of the document with the revised REMIT, which now includes the collection of LNG market data for the publication of ACER’s daily LNG price assessment and benchmark.
