Revenue increased by € 171 million, mainly due to tariff increases for electricity transmission and connection charges. The tariff increases are primarily the result of retroactive compensations for the years 2022, 2023 and 2024, as well as inflation. TenneT’s purchase costs increased by € 15 million, primarily due to a rise in the volume purchased. On the other hand, distribution losses decreased by € 1 million.

Revenue increased by 13.2% compared to the first half of 2024. This consists of an increase of 13.4% in regulated revenue (excluding other revenue) and an increase of 5.0% in other revenue.
The increase in regulated revenue is mainly attributable to a tariff increase of the periodic transmission and connection charges for electricity.
Revenue from transmission and connection fees for electricity increased by 16.8% compared to 2024. This increase is the result of an average tariff increase of 16% and a volume increase of 1%.
Revenue from gas transmission and connection fees increased by 12.9% compared to 2024. This increase is mainly attributable to an average rise in tariffs of 14% and a volume decrease of 1%.
Regulated revenue from electricity and gas metering services decreased by 32.8% compared to 2024. This decrease is attributable to an average tariff decrease of 33%. The ACM has decided that regional grid operators must settle part of the margin on metering services from the past with future tariffs. The ACM has not decided on the method to determine the exact margin, however. In anticipation of the final decision on the method, Enexis has set the metering service fee lower in 2025 than the maximum permitted fee.

Costs of transmission services and distribution losses increased by € 14 million to € 487 million in 2025. This increase comprises a € 15 million rise in TenneT's transmission service costs and a € 1 million decrease in distribution losses.
The increase in transmission service costs comprises a € 4 million tariff increase and an € 11 million increase in volume.
The decrease in distribution losses includes an € 8 million reduction for electricity and a € 7 million increase for gas. The decrease in electricity consists of - € 12 million due to price differences resulting from lower energy prices, +€ 2 million due to volume differences and +€ 2 million in other network losses, including metering errors by third parties. The gas increase consists of - € 5 million due to price differences and +€ 12 million due to volume differences. After a period of extreme energy price fluctuations, prices stabilised somewhat in 2025. This is reflected in the costs for distribution losses.
