Steep increase in transmission tariffs in 2025

Set in a context of high inflation, the 2024-2027 tariffs reflect Elia's willingness to provide the resources it needs to fulfil its essential missions to facilitate the energy transition. In particular, this involves the implementation of its ambitious investment programme approved as part of the federal development plan. With the increasing electrification of our society - think heat pumps and electric cars - there is a need for a strong high-voltage grid. Companies' electricity consumption alone will increase by half between now and 2030, notes Elia. Elia will therefore invest billions over the next few years in, among other things, the new Ventilus and Boucle-du-Hainaut high-voltage lines. The cost of the energy island to appear offshore in the North Sea is even only partly included in the new tariffs.

Specifically, Elia will invest €6.4 billion in the grid over the period 2024-2027. That is a good deal more than the €1.5 billion from the previous 2020-2023 tariff period. According to Elia: ‘These are big investments, but they will pay for themselves in just a few years. Moreover, the costs of postponement or delay would be many times higher. The economic benefits of the investments are estimated at between €750 million and €1.2 billion a year.’

In 2024, the transmission tariffs will remain broadly stable compared to the transmission tariffs in 2023, but will increase more sharply from 2025 onwards.
