Entry and Exit Capacity
The entry-exit system
GTS applies an entry-exit system where gas flows into the network at entry points and leaves the network at exit points. Shippers can book transport capacity at entry points and exit points via the PRISMA platform.
Starting 2020 GTS will offer 5 standard Capacity Products to be booked. These products are: Year, Quarter, Month, Day Ahead and With-in Day capacity. A concluded capacity booking only consist one capacity product. Every booking will have its own unique Booking ID.
GTS performs an availability test and a technical transport test for the purpose of allocating transport capacity. Tariffs have been set for all entry and exit points by the Dutch Authority for Consumers & Markets (ACM); These can be found in the Appendices to the relevant TSC. Entry capacity gives a shipper the right to inject a specific volume of gas per hour into the national grid at an entry point. Exit capacity gives the right to withdraw a specific volume of gas per hour from the national grid at an exit point.
A directly connected party [EWEX] can, if he has the required licence, book exit capacity at his connection linked to the GTS network. For shipping gas to this connection a transfer of rights is always needed from Ewex to his corresponding shipper.
GTS accepts gas that is offered at entry points, transports it and makes it available at exit points. A shipper can freely combine entry and exit points. A collection of entry and exit contracts of one and the same shipper are combined into one portfolio. A shipper may have several portfolios at the same time.
A shipper does not need to book entry and exit capacity simultaneously. As regards how the contracted capacity is used, the transport network must be in balance in order to let gas be transported safely and efficiently. Each shipper is himself responsible for the volume of gas extracted from or injected into the system. If an imbalance does arise, we will establish, for each portfolio, whether the portfolio has contributed towards causing the imbalance or if it has helped to reduce the imbalance. More information can be found under the subject ‘Balancing regime’.
