N604 to reopen to traffic

Good news! The Rabosée-Battice project is drawing to a close and the underground cable has now been pulled across the entire route.

On 4 March, contractors began work to restore the road to its original state. Asphalting work is set to run until 13 March, depending on the weather conditions.
Once the work is complete, the N604 (between Barchon and the ‘La petite Fournée’ roundabout) will be reopened to traffic in both directions. The road markings will be repainted later.

Travel news: temporary closure to traffic

On 7 January 2019, a new phase of work began on the N604 between the roundabout in Blegny giving access to the motorway to Aachen and the junction with Rue des Heids in Soumagne.

As part of this work, the section between the 'La petite Fournée' roundabout and 'Parc artisanal de Blegny' will be closed to traffic from 12 to 14 February inclusive. These dates may change if bad weather forces us to postpone the road closure.

During this period, an appropriate diversion and signage will be in place, in accordance with the mobility plan drawn up with the municipal councils and the local polices.

Shops and homes will remain accessible, as will the Parc artisanal de Blegny, and Elia will ensure that all the necessary access arrangements are in place.

December 2018

Keen to keep up the dialogue with local residents and businesses, together with the municipalities of Blegny and Soumagne, Elia wishes to update you on developments concerning the Rabosée-Battice site.

The second phase of work will begin next January on the section of the N604 between the roundabout affording access to the motorway to Aachen in Blegny and where the road crosses rue des Heids in Soumagne.

In this connection, all the local actors have approved a mobility plan. Accordingly, for the duration of the work:

  • traffic from Barchon to Soumagne should continue to flow normally;
  • motorists heading for Barchon from Soumagne will have to take a detour via exit 36 on the E42, from the roundabout "La petite fournée";
  • both shopping complexes will be accessible to vehicles coming from Barchon. Motorists arriving from Soumagne will have to take the detour via exit 36 on the E42 from "La petite fournée".

Elia guarantees that all businesses will remain accessible via the aforementioned deviations. You will find the mobility plan by clicking on this link.

According to the provisional schedule, the project should be completed during spring 2019. Should this change for reasons beyond our control, we will keep you informed via this page.

Elia will be happy to answer any questions you may have. Please don't hesitate to call us on 0800 18 002 or send an e-mail to riverains@elia.be.

Focus on directional drilling

As part of our infrastructure works, we regularly use the directional drilling technique to lay underground cables. This process is useful in minimising traffic disruption around the site. In fact, directional drilling makes it possible to avoid blocking major roads and commercial hubs during the works.

Elia is using this technique at various points of the Rabosée-Battice site. This is the case for example at the ’Carrefour des 4 bras’, straddling the Communes of Liège and Blegny, where our teams were hard at work a few days ago.

"The directional drilling technique allows the cable to pass from point A to point B without opening a trench in the road," explains Peter Nys, project manager. "We start by digging a well at the entry and exit points. The passage between the two points is then drilled. Depending on the nature of the soil, the boring head is passed through at least twice, then the ducts are pulled into the passage created. Finally, the cable itself is pulled into the ducts using traditional machinery. We will also be using this technique in the coming weeks, along the N604 in Blegny for example, to limit the impact of the site on businesses."

When organising the sites for its infrastructure projects, Elia always works in collaboration with all stakeholders (contractors, municipal works departments, police, landowners). The choice of directional drilling was considered by all to be the best solution to minimise the impact of the works for the Rabosée-Battice project on access and traffic.

Start of the work

Work on the Rabosée-Battice project has begun in Herve. Our teams will spend around 12 months laying the new underground connection between the Battice high-voltage substation and the future transition station in Rabosée.

Trenches will be dug and cables laid in sections of 800 to 1,000 metres. Each section requires four to six weeks' work, from excavation to the restoration of the infrastructure to its original state.

We are currently starting work on line 38 of the RAVeL network in the municipalities of Herve and Soumagne. Work in this area will last about four months, after which we will move on to the municipalities of Liège and Blegny.

For more information about the work and its progress, consult the 'Works' section of this website.

Public consultation and organisation of a Q&A session

The Walloon Region's delegated official has declared our planning permit application complete.

Consequently, between 6 July and 9 September the Rabosée-Battice project will be subject to public consultation. During this period, the entire application as well as the Environmental Impact Assessment (EIA) will be available for scrutiny at the premises of the four municipal administrations involved.

On a voluntary basis, in keeping with its policy of transparency, Elia is organising an evening Q&A session to answer any questions. SGS, the recognised, independent consultancy that wrote the EIA, will also be invited along to present the EIA's conclusions.

  • Where? Chamber of the municipal council (town hall): Avenue de la Coopération, 38, B-4630 Soumagne.
  • When? 5 September, free access between 18:00 and 20:00
  • Who? The project's managers and author of the EIA will be present

In the meantime, we can be reached by phone on 0800 18 002 or by e-mail at riverains@elia.be.   

9 December 2016

The preliminary project for the underground electricity connection linking Rabosée and Battice was officially announced during an advance public information meeting at Soumagne Cultural Centre on Thursday, 8 December.

We would like to thank everyone who attended the session. Your questions and comments will help the independent engineering firm to conduct the most precise and specific Environmental Impact Study possible, enabling Elia to design a project that better respects t environment.

Remember, you can still send your questions, suggestions and comments to Soumagne municipal council, with a copy to Elia, until 22 December 2016. These will be forwarded to the engineering firm, which will consider them in its analyses.

The Environmental Impact Study will last three months and its findings will be included in the planning permit application file submitted by Elia.

We will be sure to keep you updated about the next steps in the procedure.

Best regards,

The Rabosée-Battice project team

6 December 2016

Residents of the municipalities covered by the Rabosée-Battice project (Liège, Blégny, Soumagne and Herve) are cordially invited to an advance public information meeting:

on Thursday, 8 December 2016 at 8 p.m.
at Soumagne Cultural Centre
Rue Pierre Currie 46, 4630 Soumagne

Anyone wishing to make observations or suggestions may do so:

  • at the meeting;
  • or within 15 days of the meeting by sending a letter to Soumagne municipal council (Collège communal de Soumagne, Avenue de la Coopération 38, B-4630 Soumagne) with a copy to the requester (Elia Asset SA – For the attention of Mr Christophe Coq - Boulevard de l’Empereur 20 – B-1000 Brussels).

Legally, this meeting constitutes the first official announcement. The preliminary project will be presented to you in detail and those in charge of it will be available to hear your comments and suggestions, which will be noted and analysed during the Environmental Impact Study.

The Rabosée-Battice project team hopes to see you at this information session. You can also contact us by e-mail or telephone.



To meet the various consumption and generation needs identified in the region, Elia recommends constructing a new 150-kV underground electricity connection linking the substations at Battice and Rabosée (Wandre-Haut). Here, the underground link will be connected to the 150-kV Bressoux - Cheratte - Lixhe overhead connection, which will necessitate the construction of a new transition substation at Rabosée. 

The project has the following objectives:

  • support long-term growth and security of supply in the east of the Province of Liège;   
  • guarantee network reliability;
  • anticipate the end of the service life of a section of the overhead electricity connection linking the substations at Bressoux and Battice.   

Elia proposed this project as part of the Federal Development Plan, which sets out a 10 year-vision for developing the Belgian high-voltage grid. The Federal Development Plan is based on long-term consumption and electricity generation needs and was validated by the Federal Minister of Energy. 

The project 

An environmentally-friendly route

Elia does everything it can to limit the environmental impact of its infrastructure projects, in particular by meeting the Walloon Region's requirements in order to determine the best possible route.

This involves, for example, conducting as much of the work as possible on public roads and along existing infrastructure. The author of the Environmental Impact Study, conducted prior to the permit application, will make recommendations on the preliminary project submitted by Elia.

The route will be coordinated with other projects (the ALEGrO cable-laying and RAVeL projects) to limit the impact on mobility.

If the authorisation procedures unfold as expected, Elia will be able to start the works in the third quarter of 2017.

The provisional works schedule anticipates that the project will last approximately 14 months.

Trenches will be made and cables laid in sections of 800-1.000 m. Each section will take four to six weeks to construct, from opening the trench to repairing the infrastructure, meaning that local residents will only be affected for a maximum of six weeks.

Elia is committed to working closely with the local authorities and local stakeholders to find solutions limiting the impact on mobility.

Information about the works will be regularly provided to residents, via the website, a newsletter or by post.

A project with several stages


1. Holding a coordination meeting

Elia will design the stages of its projects in collaboration with the municipal authorities, police, managers of public areas and its contractors to minimise the impact on mobility as much as possible (access to homes temporarily disrupted, lorries on the road).

2. Conducting an inventory

Elia will conduct an inventory (e.g. roads and paths along the connection's route) with the authorities and contractors and commits to restoring the infrastructure to its original state after completion of the works.

3. Putting up signs

Suitable diversions and signs will be planned in consultation with the police areas.

4. Digging trenches

The high-voltage underground connection will be laid in sections of 800-1.000 m in length. Trenches of this length will be dug and reinforced. This work will take about two weeks.
Sometimes directed drilling will be carried out (under major roads and intersections or railways) instead of making open trenches.

5. Pulling conductors

The cables will then be pulled through the trench, which will take approximately two working days. 


6. Repairing roads

After the cables are laid, the trenches will be backfilled. Finally, the site will be restored in order to return all affected areas to their original state.
Backfilling and restoring the surrounding area will take around two weeks.

7. Inventory

8. Commissioning




Elia's preliminary project file is currently being analysed by the author of the Environmental Impact Study (SGS) authorised by the Walloon Region. Elia will use these findings to refine its preliminary project before putting together the final planning permit application.

In all its projects, Elia endeavours to limit noise and disruption resulting from the worksite and the use of infrastructure as much as possible, both for residents and the environment in general. As well as working closely with the authorities in charge of protecting the environment, Elia has taken a number of measures with which it complies and which it imposes on its subcontractors via the specifications.


  • Elia will coordinate this project with others projects (in particular, the ALEGrO cable-laying and RAVeL projects).   
  • If the work requires temporary road closures, suitable diversions and signs will be put in place in cooperation with the police area.   
  • Work-in-progress signs will be put up in cooperation with the local police and will provide residents with the necessary information (in particular, the worksite's start and end dates).   
  • Where possible, Elia tries to organise its worksites in such a way as to limit the impact on mobility for users (e.g. by drilling, laying conduits, working in two teams and working in July).

Limited noise from the worksite

  • Noisy work will only be carried out during working hours unless otherwise agreed with the relevant authorities in order to reduce its impact on mobility at specific times.
  • Site vehicles will only leave their engines running when necessary.

Worksite safety

  • Throughout the project, work areas will be clearly demarcated. Furthermore, a site safety coordinator will ensure the smooth running of the site.   
  • Site meetings will also be held with the contractors to discuss points of attention (e.g. itinerary and waste sorting).   


  • Healthy and local-biotope-friendly land will be used.   
  • All waste from the worksite will be collected and taken to an accredited waste processing centre.
  • The soil will be protected during dismantling operations.   
  • Some worksites requiring particular attention in terms of biodiversity will be subject to specific planning.   

Coordination with the authorities

  • Regular contact will be established with the road authorities, who will be invited to attend the weekly site meetings and check that the measures imposed as part of Elia's authorisation are properly implemented.
  • An independent surveyor is in charge of referencing the connection's exact location to ensure traceability for the road authorities.


Communication is one of Elia's priorities, along with respecting the environment and securing the region's power supply. Consequently, we will keep you regularly informed and answer any questions you may have. Please don't hesitate to contact us because we strive for total transparency, towards both local authorities and local residents!
