GTS submits tariff proposal for 2027

On 6 March 2026 GTS submitted the proposal for the transmission tariffs in 2027 to the regulator ACM. In addition, GTS calculated the neutrality charge for 2027. The neutrality charge and the transmission tariffs together form the total tariff for the capacity products of GTS.

The tariff proposal shows an average increase of approximately 4.5% compared to 2026. The tariff increase will be limited because GTS has agreed with grid users and ACM that the corrections resulting from the current regulatory period (for the years 2025 and 2026) will be distributed across the entire regulatory period of 2027-2031. This will limit the tariff increase in 2027 and ensure more stable tariff trends in subsequent years.

Households and other small consumers pay for the national transport of natural gas via their energy bill. Because the costs for the national transport of gas are only a few percent of the total energy bill, the impact of this increase for consumers in 2027 will be limited to a few euros.

The 2027 tariff proposal and the neutrality charge are further explained in the document below.

Market participants have four weeks to submit their response to the ACM.
The ACM will assess GTS's tariff proposal and the views submitted to it and will take a tariff decision in May 2026.
