Elia Group

Overview

Elia Group is the listed holding company that owns and operates electricity transmission grids in Belgium (through Elia Transmission Belgium) and in northern and eastern Germany (through 50Hertz, held jointly with KfW). In Belgium it operates the entire 380, 220, 150, and 110 kV high-voltage network, connecting domestic and offshore generation to distribution operators and large industrial consumers. The group serves around 30 million end users across the two countries and ranks among the five largest European transmission system operators.

Elia's regulated activities sit under the supervision of the federal regulator CREG and regional regulators in Belgium, with the German subsidiary regulated by Bundesnetzagentur. The group is at the centre of the energy transition in north-west Europe, building offshore connections in the North Sea, cross-border interconnectors, and onshore reinforcements needed to integrate renewable generation. Capex programmes include the Princess Elisabeth Zone offshore grid hub, the Ventilus high-voltage line in West Flanders, the Boucle du Hainaut extension in Wallonia, and the Nemo Link and ALEGrO interconnectors with the United Kingdom and Germany.

The group went through a significant leadership reset between late 2023 and early 2025. Chris Peeters left as CEO on 30 October 2023 to become CEO of bpost. Catherine Vandenborre served as interim CEO from November 2023 until Bernard Gustin took up the role on 15 January 2025. Marco Nix, previously CFO of 50Hertz, became CFO of Elia Group on 1 April 2025. As of end 2024 the group employed 4,020 people, up roughly 16 percent year on year as the energy-transition build-out scaled.
