End user with exit capacity (EWEX)
If you are a directly connected party to the national gas grid, you can agree on your required capacity with your supplier and/or shipper. Your shipper will then book the transmission capacity in the GTS network. However, you can also opt to book your own site exit capacity directly with GTS, provided that you will take on the role of end user with exit capacity (AMEX) with GTS, with the required licence (L licence).
Book your transport capacity directly with GTS
Previously, it was common for direct connected industries to have an AMEX licence, as this enabled the connected party in question to book its transmission capacity for an extended period, thereby guaranteeing the security of its gas transmission. Nowadays, GTS reserves the booked capacity for you on your connection, in the current year, up until 1 December of the following year. The exit capacity is booked as outlined in Article 2.1.2.a of the Gas Transmission Code. Connected parties are therefore guaranteed that the capacity booked for them in the current year will also be available to them in the following year, as long as the capacity has been booked on their connection before 1 December. Booking requests submitted after 1 December in the current year are processed on a first come, first served basis. The principle of booking exit capacity, thereby guaranteeing their capacities, means it is no longer necessary for directly connected parties to have or take on the AMEX role.
If you decide that you would like to book the exit capacity on your connection yourself anyway, you will need to apply for the required AMEX L licence. You can do so by completing the Licensing application form, and signing and emailing the form in PDF format to the Customer Desk at Customerdesk@gastransport.nl.
Creditworthiness
In order to attain the AMEX status, you must meet the creditworthiness requirements set out in Annex 1 of the Gas Transmission Code. This means that we will request additional financial security from you if the booking value (including VAT) of your contracted capacity exceeds your credit limit. The AMEX must provide GTS with the requested security no later than two months before the start date of the transmission booking. Additional security must be valid for four months after the end of the contracted capacity period. The AMEX’s creditworthiness will be continuously monitored during the term of the contracted exit capacity. Please click here to find out more about creditworthiness and GTS.

Transferring capacity
Once you have booked your exit capacity, you need to ‘transfer’ it to your shipper. You can do so through your supplier, with whom you have entered into a gas supply contract. Transmission rights are transferred through a trade. There are two types of trade, i.e. a Transfer of Capacity Rights (ToC) and a Transfer of Usage (ToU). With a ToC, both the capacity rights and the usage rights are transferred and the shipper to whom the capacity was traded pays GTS for the transmission rights. With a ToU, only the usage rights are transferred and the AMEX continues to pay for the transmission capacity. To initiate your transfer with GTS, please use the Changes to/transfer of (a) network area application form in the Downloads and forms section of our website.
The transfer must be registered no later than 10 working days before the gas transmission start date and the supplier must send a switch message to GTS at least 5 working days before the start of the supply. Please click here to find out more about switch messages.
As of 2020, there is no fee charged for the transfers of rights (ToC or ToU). The transfer is considered a condition on which the transmission service is provided, so the costs are covered by the all-in transmission tariffs as specified in Appendix 1 of the TSC.
