Tariff decision 2026

On Monday the 25^th of May, the GTS tariff decision for 2026 was published by ACM.

On average, the tariffs for 2026 will increase by approximately 50% compared to 2025. The tariff increase is mainly the result of (i) higher allowed revenues as a result of higher costs that are recalculated, such as energy costs and (ii) a decrease in the expected gas transmission capacity to be sold.

Compared to the tariff proposal of GTS, the ACM has replaced the estimated inflation of 1.7% from GTS’s proposal with the actual inflation of 3.8% (February 2025) in the tariff decision.

In addition to the tariffs, GTS sets a neutrality charge based on the Grid Code Balancing. This charge settles costs and revenues from balancing activities, including the pipeline buffer flexibility service, emergency settlements and costs due to defaults.

In 2026, the amount that will settled via the neutrality charge will be approximately EUR 11.7 million.

See below the calculation of the neutrality charge and the charge per capacity product.

The transport tariff and the neutrality charge are charged jointly to shippers.
