French electricity transmission network operator RTE entrusts Eiffage Énergie Systèmes' specialist high voltage subsidiary with the large-scale Avelin Gavrelle power line project (Hauts-de-France)

Eiffage Énergie Systèmes' teams have started work on this project to design, manufacture and construct 16 km of the 400,000-volt line between Lille and Arras.

The project reflects RTE's intention to upgrade power Avelin Gavrelle line, which currently supplies 530 towns. As the line layout covers an area of isolated houses (rather than housing estates) RTE launched a competition for the creation of a new pylon better suited to the landscape.  This pylon, named « Equilibre », is to replace the Treillis pylons on part of the structure. 

The turnkey project includes design, a research and development phase and the line construction. It is to be carried out in consultation and co-operation with all the local players. 
Our teams will be in charge of lifting the pylons, rolling out cable and dismantling the former line. Work is due to start in 2019 after the period of research and development, and should be finished by 2021, with commissioning scheduled for autumn 2021. 

The project will be carried out by a consortium comprising Eiffage Énergie Systèmes and Iemants (a subsidiary of Eiffage Métal based in Belgium). Eiffage Route and Génie Civil will also be called on to supply expertise in the field of access roads and pylon foundations.
