Fluxys Belgium: Yearly Auction 2025 - Exit Virtualys capacity offer
In the context of the upcoming Yearly Auctions on Exit Virtualys (BE - FR) Interconnection Point, Fluxys Belgium is enquiring whether the currently offered capacity towards France is still required, and asks interested market participants to demonstrate this by booking capacity over multiple years.
Fluxys Belgium would welcome bookings for multiple consecutive years. However in case of no or limited subscriptions from the market, Fluxys Belgium might consider a reallocation and/or a reduction of the future Exit Virtualys capacity offer.
Maintaining optimum capacity offer
In accordance with the Network Code CAM (EU2017/459), Fluxys Belgium, as Transmission System Operator, must:
• Maximize the technical capacity offer under efficient network operations
• Optimize flow and capacity distribution according to market conditions
This is necessary as inefficient use of the high-pressure networks leads to suboptimal market conditions.
Evolution of gas routes
For several years now, gas flows have shifted due to the geopolitical context. Rather than flowing from East to West as it was the case for many years, flows are now predominantly directed from West to East across Belgium.
In 2024 and in 2025, Belgium has continued to play a key role in Germany’s gas supply, with considerable flows transiting towards Germany which are supported by high imports from Norway and LNG Terminals. Conversely, flows towards France have significantly decreased in recent years.
To meet this market demand, recent investments and capacity reallocation have been carried out to enable an increase of the flows and the Firm capacity offer on Entry West zone and Exit Germany.
Hydrogen and CO2 transmission ahead
To support the energy transition and help accelerate decarbonization, Fluxys Belgium is currently assessing different alternatives to enable the transport of hydrogen and CO2, while continuing to fully support security of supply in Belgium and surrounding countries.
The following maps show the long-term outlook of Fluxys hydrogen and CO2 system in Belgium connecting industrial valleys and neighbouring countries.
Significant reduction of Exit Virtualys capacity subscriptions and use
Since 2019, bookings and utilization of capacity from Belgium to France are significantly decreasing. In 2024 and 2025, the average exit allocated capacity was around 2,1 GWh/h in comparison with subscribed capacity around 10 GWh/h. The subscribed capacity is currently underutilized.
Besides, long-term contracts are gradually coming to an end and are not replaced by new ones as no long-term bookings have been made since 2018.
Exit Virtualys capacity offer for 2025
In this context, Fluxys Belgium might consider reallocating its future capacity offer with a possible reduction of capacity towards France on Exit Virtualys.
For the third consecutive year, Fluxys Belgium is offering market participants a further opportunity to express their interest and strongly encourage them to make long-term commitment by subscribing capacity for multiple years during the Yearly Auctions of July 2025.
In the absence of long-term bookings for consecutive years, Fluxys Belgium, in consultation with CREG, reserves the right to reallocate and/or reduce the capacity offered on Exit Virtualys as from next year.
As a reminder, the Yearly Auctions on PRISMA will be held on 7 July 2025 from 9 a.m. CET to 12 p.m. CET.
