Oisquercq-Buizingen

Replacement of a three-phase 150-kV overhead power line between the Oisquercq (Tubize) and Buizingen (Halle) substations with 150-kV underground electricity cables.

Guaranteeing the national grid's reliability

As part of our efforts to guarantee our grid's reliability, we have to continually assess our facilities' performance. Now that the current overhead line is nearing the end of its life, we are redesigning this part of our grid so that we can continue ensuring the security of the region's power supply.

In the interest of society
Replacing the line between Oisquercq and Buizingen is necessary for two reasons:

The end of the current line's life
The line currently connecting the Oisquercq and Buizingen substations dates back to 1959 and is reaching the end of its life.

Guaranteeing the electricity grid's security and reliability
By replacing this line, we are guaranteeing a reliable and secure grid that can provide a continuous supply of electricity.

The route

The current overhead line has 10 pylons in Wallonia and 17 pylons in Flanders. Of these, 10 will be demolished in Wallonia and 15 in Flanders. The remaining two pylons in Flanders will continue to serve as telecommunication pylons but will be lowered.

The new 150 kV underground connection will have a total length of 14.7 km, including 6 km in the Walloon Region.

Environment

As a socially responsible company, Elia is deeply committed to the environment. It contributes actively to the energy transition and is particularly concerned with preserving biodiversity. It also works closely with local authorities, residents and all the local stakeholders affected by its infrastructure projects as it expands and upgrades its grid.

A note on the environmental impact assessment was carried out by an independent consultancy.

During the works phase, Elia also makes every effort to minimise the impact of its infrastructure projects on the local environment in which they are located.
