Entry / Exit on Interconnection Points - Belgium

Your solution to enter the Belgian market area, trade on ZTP, supply the domestic market and connect with adjacent markets

Product description

Entry services

With entry services on interconnection points, you inject a quantity of natural gas at an interconnection point into the Belgian transmission grid to supply an end-user or trade on one of the hubs. 

Exit services 

With exit services on interconnection points, you easily transfer natural gas from a zone of the transmission grid to an adjacent market area or storage.


Entry and exit services automatically give you access to the ZTP Trading Point and to the flexibility offered by the market based balancing system.



Types of capacity

Firm capacity

  • Always available
  • Usable under normal operating conditions.

Interruptible capacity

  • Cheaper than firm capacity, but may be interrupted in case of physical restrictions on our transmission grid
  • Offered when firm transmission services are available in limited quantity
  • Historically, probability of interruption usually below 10%

Backhaul capacity

  • At unidirectional interconnection points
  • In the opposite direction of the physical gas flow direction

How to book?

Use PRISMA to book the required capacity at your selected interconnection points.
