Entry and exit capacity

GTS operates an entry-exit system where gas flows into the network at entry points and leaves the network at exit points. Entry capacity gives shippers the right to inject a specific volume of gas per hour into the national grid at an entry point. Exit capacity gives them the right to withdraw a specific volume of gas per hour from the national grid at an exit point. You can book these capacities with GTS through the PRISMA platform. 

On PRISMA there are two methods for booking capacity with GTS. Auctions are used for all connections to other entry and exit systems. DSO contracting is used for connections to distribution networks. If you are feeding in gas from a small field, this is governed by special contractual provisions, known as the SFA. At all other points, the FCFS principle, First Come First Served, is used.

Since 2020, it has been possible to book transport capacity by choosing one of five standard products, i.e.: Yearly, Quarterly, Monthly, Day and Within-Day products. Separate contracts must be concluded for each product and every booking will be given its own unique Booking ID.  GTS performs an availability test and a technical transport test for the purpose of allocating transport capacity. 

The Dutch Authority for Consumers and Markets (ACM) has set tariffs for each entry and exit point; these can be found in appendix 1 of the relevant TSC. 

Provided it has a special licence to do so, a party that is directly connected to the GTS network [EWEX], such as an industry, can book exit capacity itself at its connection that links up with GTS’s network. Because the directly connected party cannot ‘ship’ gas itself, the booked capacity must always be traded to a customer with a  shipper licence.

GTS accepts gas offered at entry points, transports it and makes it available at exit points. You can freely combine entry and exit points. A portfolio brings together a collection of entry and exit contracts relating to the same shipper. You may have several portfolios but remember that all portfolios must be kept in balance separately by you.

You do not need to book entry and exit capacity simultaneously. When using the contracted capacity, you should be aware that the transport network must be in balance so that gas can be transported safely and efficiently. You are yourself primarily responsible for the volume of gas you withdraw or feed in. If an imbalance does arise, we will establish, for each portfolio, whether the portfolio contributed towards causing the imbalance or whether it helped to reduce the imbalance, and this may involve costs. More information can be found under the subject balancing regime.

If you are (temporarily) unable to book via PRISMA, you can fill in the form below, sign it and send it to customerdesk@gastransport.nl.
