ACER has announced that the formats used for Table 4, used for reporting of gas transportation contracts under REMIT, will be updated. The older versions of Table 4 will no longer be accepted from October 2023. The changes are detailed in this announcement which links to the updated TRUM (Transaction Reporting User Manual), MoP (Manual of Procedures), schemas and other relevant documents.

The changes primarily permit new values to be used in certain fields. For example, it is now possible to use an “ACER Code” as an identifier rather than only an EIC “X” code, which was previously the case using Table 4. The changes are based on a consultation that was run several years ago (see here).
