Project to replace 150-kV overhead line between Ruien (in Flanders) and Chièvres with an underground connection 

Addressing an ever-present need

The 150-kV overhead line between Ruien (in Kluisbergen, Flanders) and Chièvres is nearing the end of its service life. Since it is necessary for the region's security of supply, Elia plans to replace the line with a 150-kV underground connection.

The current overhead line passes through the municipalities of Kluisbergen, Mont-de-l'Enclus, Celles-en-Hainaut, Frasnes-les-Anvaing, Leuze-en Hainaut, Ath and Chièvres.

Specifically, Elia is planning the following sequence:

  • Submit the permit applications for the underground connection project;
  • Once the permits have been secured, build the underground connection;
  • Dismantle the current overhead line.
