Exit capacity to Distribution System Operators

GTS makes Distribution System Operator (DSO) exit capacity available for exit points connected to the distribution network . At these points, gas flows from the national grid into the distribution network.

Which shippers can have DSO exit capacity?
If a shipper wants to inject gas into the distribution network, the shipper needs to have a B Licence. More information about licencing can be found on our website, under Licencing.

Do I have to book the capacity on DSO exit point?
The capacity at these points does not need to be pre booked by shippers. GTS books this capacity for the shippers on a monthly basis. The booking can be corrected 4 months later, if necessary.

What is the booking based on?
The booking is based on data of the connection register (in dutch: Centraal aansluitregister). The connection register registers the standard yearly usage for profile customers and the maximum usage for telemetry large-scale users. Energie Data Services Nederlands (EDSN) is the admin of the connection register. Each month, the DSO’s collect the data from the connection register and sends this data to GTS and shippers.

How does GTS calculate the capacity and amount that they invoice?

GTS calculates the capacities and the to be invoiced amounts based on the received yearly usage, maximum usage, and the factors and fractions shown in the table below.

Capacity profile users = Yearly usage * Hourly fraction * Fitfactor profile
Capacity telemetry large scale users = Max usage* profile factor * Fitfactor telemetrie

Amount = Capacity * Tariffs * Monthly fraction

How often does GTS revise the factors?
We have revised the profile factors and monthly factors Telemetrie per 1 january 2018. We determine the hourly fractions and monthly fractions for profile users annually and the fitfactors each month.

Where can I find more informaton on DSO exit capacity?

  • For a detailed description of calculation of DSO exit capacity and the factors we use, see Transmission Code Gas article 2.1.2_b to 2.1.2_g
  • For more information on the monthly fraction (in Dutch: maandfractie), see article of the Tariff Code Gas.

What will change from 1-1-2020?

On 11 December 2018 ACM published the final NC TAR decision. This decision describes the new tariff structure and conditions applicable as of 1 January 2020. This also has consequences for DSO/LDC capacity product calculations and cost calculations. In the Excel file below (‘Factors and fractions DSO exit 2020 + calculation tool’) you can use a quick calculator to calculate the DSO exit costs and two other sheets explain the calculation method.

Introduction Virtual Point for distribution Companies (VPC)

As of 1 January 2020, the same reserve prices apply to all DSO exit points. This will enable us to optimise/simplify the booking and billing process. In order to minimise the number of contracts, from 2020 GTS is going to add up all DSO exit capacities for each shipper and record them on a new (virtual) DSO exit point: the Virtual Point for distribution Companies (VPC).

Due to the discontinuation of the backhaul service, the current service on the VPI will be amended from 1 January 2020. Shippers will need to book sufficient entry capacity on the VPC for gas that is fed into the GTS network from a distribution network. They can do so by filling in the ‘Request for entry and/or exit capacity form and sending it to our Customer Desk.

What will change at GTS following the purchase of network losses in distribution networks by distribution network operators?

As of 1 January 2020, the distribution network operators will be required by law to cover network losses on their network. For the purpose of settling these network losses, the new GMN gas take-up category has been added to the Allocation Code Gas and the Transmission Code Gas - TSO. The Allocation Code Gas specifies how these network losses in the distribution networks are allocated to the shipper. In determining a shipper’s DSO exit capacity, the annual volume for the GMN gas take-up category is used along with the fractions and factors of the G2C gas take-up category, in line with the amended Transmission Code Gas - TSO.
