More gas transmission in 2025

Gasunie Transport Services* transported 6.2% more natural gas in 2025 than in 2024. In total, the network operator transmitted 63.4 billion m³ of natural gas (2024: 59.7 billion m³), providing 685 TWh (2024: 639 TWh) of energy with an economic value of over €25 billion*. The increase was largely due to more gas being stored in gas storage facilities, power stations consuming more gas and more gas being exported to Germany. The total domestic gas consumption was practically the same as in 2024 (a 0.3% decrease).

The figures conceal a clear shift. Gas transmission to industry fell due to a 9% drop in demand, while consumption by power stations rose by over 17%. Electricity producers turned to natural gas more often to absorb fluctuations in solar and wind production. 

* Based on the average monthly price on the TTF trading platform, which was between €37-38 per MWh in 2025.

During cold, dark winter days in particular, when there was little sun or wind, record volumes of gas were transmitted to power stations to maintain electricity production. This meant that in 2025, natural gas played a more important role as a flexible energy buffer than in 2024, and helped to ensure energy security when it comes to electricity.

Cross-border transport rose by 8.2%, largely due an increase in exports to Germany. Transport to Belgium dropped. The strong growth in imports of liquefied natural gas (LNG) is striking. For the first time, more LNG was imported than gas through pipelines (including from Norway). LNG imports rose by some 25.3%, representing an increase of 4.2 billion m³. Furthermore, in May a record volume of 2 billion m³ of LNG was imported – the highest monthly import figure ever.

2025 saw 21% more gas transported to Dutch gas storage facilities. Injection into German storage facilities (directly connected to the GTS network) also increased (+26%). Although more gas was injected into the storage facilities during 2025 than in the previous year, at the start of this winter, the facilities were less full than in 2024. This is because the gas storage facilities were relatively empty in spring 2025.

The feed-in of biomethane rose sharply in 2025 by 51.2%. However, the proportion of biomethane is still low compared with other domestic entry flows. In 2025, a total of 46 million m³ of biomethane was fed into the GTS network. This biomethane came from biomethane importers that feed directly into the GTS network, and the biomethane booster, which transports biomethane from the network of a regional TSO to the GTS network.

The security of supply and transmission of natural gas remained as high as ever. Once again in 2025, GTS could almost 100% guarantee a continued supply of gas to the whole of the Netherlands and surrounding countries.
