Tariff information as of 2020

For tariff information for the years before 2020, please see this page.

As of 2020 the tariff structure is based on the principles of the ‘Network code on harmonized transmission tariff structures for gas’ (NC-TAR), decided by the European Commission. Based on these principles the Dutch regulator ACM has decided that starting 2020 there will be an uniform all in tariff for all network points (the so called post stamp methodology). Within this structure there will be only a difference between entry-storage, entry-non-storage, exit-storage and exit-non-storage. For these purpose four year reserve prices are determined. ACM then used these tariffs to calculate the reserve prices for the 5 possible capacity products (year, quarter, month, day and within-day). In this calculation the seasonal factors and multipliers are used. You can find all reserve prices in Appendix 1 of the TSC.

Capacity can only be contracted  for periods according to the above mentioned products year, quarter, month, day and within-day. A desired booking that differs form the duration of these products, must be split into several bookings to cover the desired period. Also a desired profiled booking must be split into several bookings.

A yearly product can start at every desired month, a quarterly product only at January 1st, April 1st, July 1st or October 1st. It is however possible to book a yearly, quarterly or monthly product after the start of the desired period, for yearly and quarterly this is only possible in the first month of the desired period. For the days before the desired start date of the booking we will then book capacity ZERO.

Capacity products type year, quarter and month will always end at the last day of the (last) month of that product.

At the shippers request, GTS can retrospectively optimize a combination of contracted quarterly, monthly and/or daily capacity products to the cheapest combination. Such a request from the shipper will only be granted if the bookings have been made on the same day, for the same network point and, of course, in the same direction. For this purpose, GTS offers two calculation tools (one for a profiled booking and one for a non-profiled booking) to be used by shippers to determine in advance the optimized combination of the bookings (and the costs) to be made.

Below you can find an example of a profiled booking and the optimization that can be made.
Desired profile:

This can be optimized:

Therefore this results in 5 separate bookings: 1 yearly booking, a quarterly booking for Q1, a quarterly booking for Q4, a monthly booking for January and a monthly booking for December.

Exceeding Capacity

capacity overshoot, for which a surcharge is applicable and effected, occurs when per day the contractual entry capacity and/or exit capacity is exceeded by more than the operational margin of 2% per hour. Only the highest capacity overshoot per gas day will be charged.

The amount of the surcharge is based on the difference in value between the booked capacity and the actual capacity used multiplied by the valid monthly factor multiplied by the annual network point tariff (transport tariff + balancing tariff + quality conversion tariff valid at the network point concerned).

If the entry and / or exit capacity contracted per gas day at the GTS network point is exceeded, this will lead to a capacity overshoot. GTS charges a tariff for this to the network user. Only the highest capacity excess is charged per gas day.

The rate for the excess is equal to the rate for a monthly capacity product associated with the month in which the excess occurs.

The amount due for an excess consists of the difference between the booked capacity (sum of the usage rights per hour per gas day) and the actually used capacity (the offline allocation value), which is multiplied by the rate for the corresponding monthly capacity product.

FAQ

  • The cost per month for Yearly product can be calculated as follows: cost (Euro) = booked capacity * reserve price * number of days in month / number of days in year (= 365 or 366).

    The reserve prices depend on entry/exit and storage/non-storage and can be found in Appendix 1 of our TSC

  • The cost per month for Quarterly product can be calculated as follows: cost (Euro) = booked capacity * reserve price * number of days in month / number of days in quarter (= 90, 91 or 92).

    The reserve prices depend on entry/exit and storage/non-storage and can be found in Appendix 1 of our TSC.

  • The cost per month for Monthly product can be calculated as follows: cost (Euro) = booked capacity * reserve price.

    The reserve prices depend on entry/exit and storage/non-storage and can be found in Appendix 1 of our TSC.

  • The cost for Day product can be calculated as follows: Cost (Euro) = booked capacity * reserve price.

    The reserve prices depend on firm/interruptible, entry/exit and storage/non-storage and can be found in Appendix 1 of our TSC.

  • The cost for Within-Day product can be calculated as follows: Cost (Euro) = booked capacity * reserve price * number of hours booked / number of hours in day (= 23, 24 or 25)
