Tariff decision 2019

18 May 2018

On May 18th 2018, the Netherlands Authority for Consumers and Markets (ACM) took the tariff decision concerning the GTS tariffs for 2019. This tariff decision contains tariffs for transport, quality conversion, balancing, existing connections and connection points. ACM completely adopted the tariffs of the tariff proposal submitted by GTS.

From now on, ACM takes the tariff decision around May. This is because the new European network code on tariff structures (NC-TAR¹) specifies that the annual tariffs must be known no later than one month before the annual auction.

In the tariff decision, the tariffs increase by an average of 2% over the tariffs for 2018. This increase is the result of a number of different effects. The application of the x-factor has a downward effect on tariffs. On the other hand, the expected fall in sales in 2019 has an upwards effect² because of the revenue-cap regulatory system. Furthermore, the annual tariff corrections in 2019 have a smaller downward effect on tariffs than the annual tariff corrections in 2018. These tariff effects are explained in more detail in the appendix.

The tariff changes vary according to the statutory task, and consequently the tariff changes for each individual entry point and exit point will also vary. For example, the transport tariffs will increase (+4%), while the tariffs for existing connections (-12%), quality conversion (-8%) and connection points (-17%) will fall.  The tariff for balancing remains unchanged. The aforementioned tariff changes are also explained in the appendix.
