Latest Updates Since the November-December 2025 Subscription Window
- As part of our continued commitment to provide enhanced operational flexibility, we are pleased to inform you that the GIS Exceeding Factor for upcoming Storage Year 2026-2027 will be set at 106% as from 1 April 2026.
All contracted capacity for this period will therefore benefit from to this increased storage flexibility. - We would like to remind you that Fluxys Belgium has launched a Market consultation on 2 February with the aim to align its regulated storage documents with the latest provisions of the European Storage Regulation. More specifically, Fluxys Belgium proposed that the existing binding Filling Trajectory becomes explicitly indicative, while the binding 90% Filling Target remain in place and should be met by 1 December. However, the target may be relaxed earlier if it is reached at any point between 1 October and 1 December.
Market feedback has been captured with the submission deadline that was set on 23 February. We are now awaiting decision from CREG, which is expected to be published before the end of the current subscription window.
All SSA registered clients will be informed in due time once the CREG decision has been communicated and the updated documents are published on Fluxys website.
