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

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.

  • texteIn 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.
  • texteThe route

    The new 150-kV underground line, which will feature one three-phase transmission line, will have a total length of 14.7 km, of which 6 km will be in the Walloon Region and 8.7 km in Flanders.
