Public consultation !!! Transparent and harmonized rules as well as clear SINGLE price signal are essential for market confidence - especially in complex situations like partial decoupling. --> That’s why the Belgian Multiple NEMO Arrangement (#MNA) is being updated and is open for consultation! Belgian market parties are invited to share their views on this update. Following new requirements introduced in July 2024 under the Electricity Market Design Reform, and the need to avoid unclear situations with multiple price signals in zones where more than one power exchange (NEMO) operates, Core TSOs and NEMOs - aligned with Core NRAs and EU Agency for the Cooperation of Energy Regulators (ACER) - decided to reopen the Core Multi-NEMO Arrangements (MNAs). The goal: ensure transparent rules for providing a single day-ahead reference price in partial decoupling scenarios. The Belgian MNA has been rewritten by Elia Transmission Belgium in close collaboration with current (and future) Belgian NEMOs: EPEX SPOT, Nord Pool, EXAA Energy Exchange Austria, and Etpa - A new way of power trading. Key updates include: - Reflecting the 2025 Day-Ahead and Intraday market coupling ecosystem (previous version dated from 2016). - Simplifying decoupling cases to align with #SDAC terminology. - Replacing local auctions in partial decoupling with volume allocation coupling at #SDAC price, avoiding multiple price signals in the Belgian bidding zone. The consultation runs from 21 November 2025 to 19 December 2025. The report will be submitted to CREG - Commission for Electricity and Gas Regulation - Belgium together with the updated #MNA for approval. More details are available on the consultation page. Thanks a lot, Claire Jonet, for the really efficient coordination! https://lnkd.in/ebRdZ7G2
