Presentation of project to local residents

The Quevaucamps-Harchies project reached an important milestone on 19 March 2019, when Elia held an advance public information meeting to present it to local residents.
The meeting gave attendees the chance to share their comments and suggestions about the optimised new route that was put forward. Their feedback will be taken into account in the
Environmental Impact Assessment, which will be carried out by accredited independent engineering firm CSD Ingénieurs.

Q-H RIP mars 2019


If you were unable to attend the meeting or the information sessions held on 20 and 21 March, do not worry! You can submit your comments, observations and suggestions any time before 3 April by sending them to Bernissart Municipal Council (Collège communal de Bernissart, Centre Administratif du Préau, Rue du Fraity 76, 7320 Bernissart), with a copy to Elia (Elia Asset s.a., Boulevard de l’Empereur 20, 1000 Brussels).


CSD Ingénieurs will address the specific concerns raised by residents’ feedback in its Environmental Impact Assessment and will suggest reasonable alternatives.
Please feel free to contact the Elia team if you would like more information or if you have any questions. You can call us on the freephone number 0800 18 002 or email us at riverains@elia.be.

Quevaucamps-Harchies: reconstruction of a line section

Elia intends to reconstruct a section of the overhead line between the Quevaucamps substation and Harchies along a new, improved route. This section comprises 14 pylons and will stretch 5.4 km through the municipalities of Bernissart and Beloeil. Following this reconstruction, Elia also plans to dismantle the existing section.

As part of the legal procedure, the project will be presented to local residents during the advance public information meeting on 19 March at 19:30 p.m. at the Maison rurale in Blaton (Rue Emile Carlier 15). This meeting is an opportunity for residents to officially make observations and suggestions regarding the project.

Two additional information sessions have also been organised. They will be held between 6 p.m. and 8 p.m. and will be attended by Elia project managers:

  • In Harchies on 20 March: Salle communale, Rue Albert Ier
  • In Beloeil on 21 March: Salle polyvalente, Rue de Mons 45 (in the school)

The Quevaucamps-Harchies project entails reconstructing a section of the overhead power line between the Quevaucamps substation and Harchies along a new, improved route. This infrastructure is essential for ensuring the grid's reliability and integrating renewable energies into it.


This project meets three objectives:

  1. To modernise a section of the current line passing through the municipality of Bernissart, which was built in 1962. Nearly 60 years on, the conductors on this connection are reaching the end of their useful life and therefore need to be replaced.
  2. To ensure the grid's and local residents' safety: by modernising the infrastructure, Elia is ruling out the risk of conductor breakage and increasing the line's energy transmission capacity.
  3. To standardise all overhead lines: the conductors along this section have a lower energy transmission capacity than the rest of the line. The new section will have conductors with a power transmission capacity compatible with the rest of the line and current standards.


The project

The new section, equivalent to the current 2x150 kV line operated at 2x70 kV until at least 2030, passes through the municipalities of Beloeil and Bernissart. Once this section has been built, the line currently in use will be dismantled.

A new, improved route

Since 1962, Bernissart has become more built up with houses constructed very close to the line.

Replacing the conductors would necessitate a significant strengthening of the current pylons, i.e. by:

  • completely shutting down the line, which is not a viable option, since the local electricity supply has to be guaranteed;
  • by installing temporary pylons, which is also unacceptable, in view of the built-up setting.

Therefore, as a responsible company anxious to improve local residents' living environment, Elia decided to rebuild this section of line along a new, improved route that takes it as far away as possible from built-up areas.



To enable the implementation of the Quevaucamps-Harchies project, various authorisations are required, tied to different specific procedures.

  • 19 March 2019: Advance public information meeting in Blaton.
  • 20 and 21 March 2019: Additional information meetings in Harchies and Beloeil respectively.
  • March-June 2019: Completion of the environmental impact study by an independent, approved design office.
  • July 2019: Submission of the application for planning permission to the Public Service of Wallonia (SPW).
  • September 2019: Public consultation process.
  • 2020-2021: Construction work on the new section of line.
  • 2021-2022: Dismantling of the current section of line.

While the work is being carried out, and current estimations suggest it will last two years, Elia undertakes to do everything it can to limit its impact and protect the local residents' peace and quiet as well as the environment (in the broad sense of the term).

Accordingly, since the local electricity supply has to be guaranteed, the work will be broken down into two stages:

Stage 1: Construction of the new line


  • Phase 1 - Lopping and clearance: Lopping/clearance work may be required at some points along the route. This will be done in consultation with the respective land owners and operators.
  • Phase 2 - Making the site accessible: After surveying the area with local owners and/or tenants, temporary access roads will be built for the intermittent traffic needed to carry out the work.
  • Phase 3 - Laying foundations: The soil removed to create these foundations will be taken away by dump truck.
  • Phase 4 - Erecting pylons: The lattice supports will be transported by lorry. They will arrive in separate parts and be assembled and erected on site. Finally, cables will be pulled from one end to the other so that they can be attached to the metal crossarms.
  • Phase 5 - Clearing up the site: As soon as the project is finished, the temporary access roads will be dismantled and the land will be restored to its original state. All waste from the site will be collected and taken to an accredited waste processing centre. Then, a final survey of the area around the site will be carried out.
  • Phase 6 - Fostering biodiversity : Elia will seek partners to implement projects aimed at fostering local biodiversity.

Stage 2: Dismantling the current line

Phases 1, 2 and 4 of this stage are similar in all respects to the construction stage.

  • Phase 3 - Taking down the old pylons: The old supports can only be dismantled once the new line has been commissioned. The conductors will be removed section by section and immediately rewound using pulling and braking machines. The pylons will be dismantled and the foundations will be removed from the ground and taken away by lorry.


As a responsible company, Elia is deeply committed to the environment and intends to make a positive contribution to the energy transition by focusing on biodiversity, local residents, local partners and stakeholders when developing our grid.

We're aware that our infrastructure works can affect local residents and the environment. That's why we make every effort to limit their potential impact as far as possible.

In addition, an environmental impact study (EIS) will be conducted by an independent design office. Among other things, this study will respond to all the suggestions made at the advance public information meeting.
