On 16 December 2022, ACER published the 28th edition of the Questions & Answers on REMIT. This edition includes new reporting guidance on battery storage contracts (Q&A III.3.51), electric vehicle charging stations (Q&A III.3.52), reliability options contracts (Q&A III.3.53), and metering data-based nominations (Q&A III.4.7). The updated Q&As also clarify the reporting of external factors affecting the production of a unit (Q&A III.7.16) and the qualification of inside information for non-EU facilities (Q&A III.7.24).

Additionally, the updated Q&As on REMIT reflect that the disclosure of inside information will be expected to take place exclusively through Inside Information Platforms as of 1 January 2023, meaning that market participants will no longer be able to use their corporate websites for that purpose, either as a primary or backup solution.
