About Elia

Elia Transmission Belgium operates the electricity transmission network in Belgium. We manage the Belgian high-voltage transmission grid (30 kV to 400 kV), which comprises over 8,802.50 km of overhead lines and underground cables. We preserve a service reliability level of 99.99 % and ensure that production and consumption are balanced around the clock. In so doing, we provide society with a robust power grid, which is important for socioeconomic prosperity. 

In the interest of society

Our company plays a crucial societal role by transmitting electricity from generators to distribution systems, which in turn deliver it to consumers. We also play an essential role in the economy, since we supply major companies which are connected to our grid wit power. In carrying out our projects, we manage stakeholders in a proactive way by establishing two-way communication channels between all relevant parties very early on in the development process. We also offer our expertise to different players across the sector in order to build the energy system of the future.

An integral part of Elia Group

Elia Transmission Belgium is part of Elia Group, one of the five largest transmission system operators in Europe. Elia Group supplies 30 million end users with electricity through its subsidiaries in Belgium (Elia) and in the north and east of Germany (50Hertz). In addition to its activities as a transmission system operator, Elia Group provides consulting services to international customers through its subsidiary Elia Grid International. In recent years, the Group has launched new non-regulated activities such as re.alto (the first European digital marketplace for the exchange of energy data) and WindGrid (which focuses on the development of offshore electricity grids in Europe and beyond). Elia Group is a listed company whose core shareholder is the municipal holding company Publi-T.

We are making the energy transition happen

We are a driver of a successful energy transition, helping to establish a reliable, sustainable and affordable energy system. By incorporating ever-increasing amounts of renewable energy into our grid, we are promoting both the integration of the European energy market and the decarbonisation of society. We also continuously optimise our operational systems and develop new products so that new technologies and parties can access our grid, thus further facilitating the energy transition.
