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 societyReplacing 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 end of the current line's life
-
The routeThe 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.
