Diversion

Below you will find further explanation of diversions and the diversion procedure. The formal rules for a diversion are laid down in Article 2.1.7 of the Transmission Code Gas TSO.

You can request a diversion by submitting the diversion request form. Make sure you send the completed and signed form, in PDF format, to the Customer Desk on time. A diversion cannot be requested on PRISMA. Diversions are available only for firm capacity.

We offer the diversion service for various combinations between virtual interconnection points (‘VIP’) and domestic points (‘FCFS’), i.e. from FCFS to FCFS, from VIP to FCFS, from VIP to VIP, and from FCFS to VIP. The full list of combinations can be found in Appendix 3 of the applicable TSC.

Since the introduction of VIPs on 1 April 2020, capacity can no longer be diverted  from or to an interconnection point (‘IP’). If you want to divert capacity away from an IP to another network point (through FCFS or VIP), you will first have to transfer this capacity to the relevant VIP. You can do this using the VIP transfer service. Details of the VIP transfer service are available on our website.

Both in terms of the procedure and the tariff, a diversion to a VIP is subject to different rules compared with a diversion to a FCFS network point. We will go into this in greater detail in the following. The different rules are a result of the difference between Article 2.1.7.3 (diversion to a VIP) and Article 2.1.7.4 (diversion to an FCFS network point) in the Transmission Code.

Whenever you submit a diversion request, we will inform you of the results. As soon as the diversion has been registered contractually, you will receive an email confirmation with details of your contract positions in Gasport.

A request for an FCFS-FCFS or VIP-FCFS diversion must be submitted to GTS using the above form. Please make sure we have the completed and signed form at least 10 working days before the requested diversion start date. If the requested capacity is available on the FCFS target network point, we will divert the capacity from the source network point to the target network point. For these kinds of diversions, you will be charged the highest of the two tariffs for the network points in question (transmission tariff and from 2021 also the neutrality charge). For this kind of diversion (to an FCFS network point), the type of capacity product on the source network point is taken into consideration. 

To illustrate, the tariff of an entry VIP - FCFS (gas storage) diversion for the months of January and July 2021 from a yearly contract for 2021. For the tariffs used for each capacity product, check the ‘Total prices’ tab of Appendix 1 of the current TSC for 2021. All tariffs in this example have been rounded to two decimal places.

• For the capacities on the source network point for both the months in question, the tariff is €0.15/kWh/h (€1.80/kWh/h multiplied by the term of 31/365).
• The tariff for the same months in a new yearly contract for the target network point is €0.06/kWh/h (€0.72/kWh/h multiplied by the term of 31/365).
• A diversion cannot lead to a shipper paying a lower price for capacity than initially contracted. Even though a discount is given on the target network point because it is a gas storage facility, the higher tariff of €0.15/kWh/h will be payable for the capacity transferred.
• Even though a monthly product for January 2021 is subject to a higher tariff of €0.16/kWh/h, we do not have to charge this tariff for this type of diversion (to an FCFS point).
• You will not be charged on the source network point for the diverted capacity.

VIP-FCFS and FCFS-FCFS diversions can be contracted for daily, monthly, quarterly and yearly capacity products, not for within-day products.

A request for a VIP-VIP and FCFS-VIP diversion must be submitted to GTS before the auction. Please make sure we have the completed and signed form at least 10 working days before the start of the auction at which you intend to contract the capacity you want to divert. It will then be up to you to contract the capacity you want to divert at the auction on the target VIP. After you have contracted this capacity, we can further process your diversion request. If the capacity you were able to contract at the auction is less than the capacity you intended to divert, we will limit the diversion to that lower contracted quantity.

After the auction, we will reduce the capacity to be diverted at the source network point. For the diversion, you will be charged the reserve price (and from 2021 also the neutrality charge) of the capacity product you bought at the auction. If the auction is subject to an auction premium, you will of course also be charged that premium. Again, the diversion cannot lead to a shipper paying a lower price for capacity than initially contracted. If the total price for your capacity on the source network point is higher, you will be charged the difference additionally, as explained in the following example.To illustrate, the tariff of a VIP - VIP diversion for the months of January and July 2021 from a yearly contract for 2021. For the tariffs used for each product, check the ‘Total prices’ tab in Appendix 1 of the current TSC for 2021. All tariffs in this example have been rounded to two decimal places.

• For the capacities on the source network point for both the months in question, the tariff is €0.15/kWh/h (€1.80/kWh/h multiplied by the term of 31/365).
• For the capacity on the target network point you contract at the auction (assuming an auction premium does not apply) the total price is €0.41/kWh/h for the January monthly capacity and €0.13/kWh/h for the July monthly capacity.
• After registering the diversion, you will be charged the highest of the total prices for the diverted monthly capacity on the target network point (a VIP), i.e. €0.41/kWh/h for January and €0.15/kWh/h for July (instead of €0.13).
• You will not be charged on the source network point for the diverted capacity.

VIP-VIP and FCFS-VIP diversions can be contracted only for monthly, quarterly and yearly capacity products, not for day and within-day products.
