Transmission services

GTS uses an entry-exit system, in which the gas enters the grid at entry points and leaves the grid at exit points. Shippers can book transport capacity at entry points and at exit points. Before awarding transport capacity to a shipper, GTS performs an availability and a technical transport test. Tariffs have been set for all individual entry and exit points. Entry capacity gives the right to inject a specific volume of gas per hour into the national gas transmission grid at an entry point; exit capacity gives the right to extract a specific volume of gas per hour from the national gas transmission grid at an exit point.

GTS accepts gas that is offered at entry points, transports it and makes it available at exit points. GTS also determines the actual transport route. A shipper has a free choice of a combination of entry and exit points. The combined entry and exit contracts are called a portfolio. A shipper does not have to book the entry and exit capacity at the same time. However, he is obliged to ensure that his portfolio balances the volume of gas that he injects into the system and the volume that he extracts from it. To achieve this, GTS has introduced a balancing regime (see Chapter 4). A shipper can have several portfolios. There is a specified handling period between the booking of the transport capacity and the actual transport. This allows GTS to complete the request in time.

Other services are e.g.; Tolerance, TTF, Gasexchange etc. For information about these services see the website for Shippers/Traders.
