Elia fits bird diverters to its high-voltage lines by helicopter

For the first time, Elia, the Belgian electricity transmission operator, is using a helicopter to fit bird diverters.

This technique is used to ensure the safety of workers on this hard-to-reach line. It also offers the advantage of working faster. Elia will equip the high-voltage line with 270 bird diverters. These diverters allow birds to see the lines better and thus avoid them. This action is part of the Elia Group's sustainability programme, ActNow, which includes limiting the impact of our infrastructure on the environment. Diverters have already been fitted to 140 km of high-voltage lines.   

  • 270 diverters will be fitted in 3 days; 
  • With a diverter fitted every 20 metres, almost 3 km of high-voltage lines will be made bird-safe; 
  • Studies show that these diverters can prevent 90% of bird collisions with high-voltage lines
