Renewable energy


Well-designed development of renewable energy is a way to combat climate change, even though it is difficult to predict this renewable energy long in advance.


EDF Luminus maintains, innovates and develops its production capacity in renewable energy from ecological as well as economic considerations:

  • the production of renewable energy by the hydropower plants is reasonably predictable in the short term;
  • onshore wind energy is the technology that most closely approximates economic maturity;
  • the installation of solar panels can help customers reduce their ecological footprint and their invoice.


As the largest Belgian producer of electricity generated by hydropower plants or onshore wind turbines, EDF Luminus invests huge amounts in the maintenance and development of its production capacity of renewable energy.


In order to expand its wind farm, EDF Luminus is constantly looking for new sites suitable for the construction of windmills. In order to keep the hydropower plants in operation, EDF Luminus continues to renovate them in accordance with the law.

Building a wind farm: a process of at least five years

The realization of a wind farm takes at least five years, from the prospection phase to the commissioning. The whole process can take even more time, mainly through appeal procedures that have become systematic:

Fase 1 -




Preliminary research and preparation of the permits: this phase includes the feasibility study, the land acquisition, the environmental impact report, the preparation of the electrical connection and the dossier for the license application.

 Fase 2 -




Authorization procedure: administrative procedures at regional and provincial level take at least eleven months. This phase can result from an appeal procedure before the competent minister, the Council of State or the Council for Permit Disputes.

Fase 3 - 



Technical and legal research after obtaining the permits. EDF Luminus draws up a technical and financial file to prepare the investment decision.

Fase 4 - 



The construction of the windmill. After the necessary decisions have been made about the investments, it will take at least eleven months before the wind turbine is really operational.


30 wind turbines built in 2017: a record for Belgium

In 2017, EDF Luminus strengthened its leadership in the onshore wind energy sector.


Total capacity rose from 300 MW to 376 MW, an increase of 25%, with a total of 161 wind turbines.


In a current record for Belgium, in one year 30 wind turbines were built on 9 sites: Floreffe, Dendermonde, Tournai, Ciney-3, Kallo, Lochristi, Leuze, Estaimpuis and Dessel.

*The graphic published on page 52 of the sustainable development report 2016 contains an error in the number of wind turbines: 131 wind turbines (and not 134) had been built and 128 (not 131) were in service on 31 December. These figures are corrected.

Ampsin hydroelectric plant: the renovation continues

Since 2016, the Ampsin hydroelectric plant has been undergoing a three-year renovation project. The total cost for the works will be 4.2 million euro. This 10 MW plant has been in operation since the 1960s; the renovation will enable it to remain in operation for another 20 years.


In 2017, the renovation focused on changing the medium voltage substation, waterproofing the roof and refurbishing the control system of one of the four turbines. This work was completed without significant impact on the plant's production.


For 2018, the Executive Committee of EDF Luminus has approved the continuation of the works on the three remaining hydraulic power units. This final phase of the work will begin in June 2018, at the beginning of the low water period, and will continue through the end of the year. 


Each year, on average, the Ampsin plant produces the equivalent of the electricity consumption of 11,143 families.


58 million euro invested in onshore wind energy

In 2017, EDF Luminus invested 58 million euro to build new wind turbines. This amount does not reflect the record increase in production capacity in 2017, as a large part of the investments had been made in 2016, for works to be finished in 2017.


In September 2017, EDF Luminus acquired 100% of the capital of the company Windkracht Vlaanderen bvba, owner of wind energy projects at various stages of maturity, including several approved permits.

Nineteen new permit and new investment applications

In 2017, permit applications were submitted for 19 projects: Geel West, Rossel, Fleurus, Eeklo Vrouwestraat, Herentals, Liernu, EOC Evergem, Alken, St-Lambrechts-Herk, Mercatordok Gent, Tongeren industrie, Lissewege, Colas Feluy, Hannut, Halen and Cosucra, for a total of 118 MW.


The Board of Directors approved the proposed investments in Lierneux and Villers 4, for a total of 18 wind turbines.

Renewable energy production: wind energy increase

In 2017, wind energy production rose (+21%), due to the increased number of wind turbines in operation. This increase was not as large as the increase in the installed capacity (+25%) due to the calendar for the construction of the new wind turbines, which were generally delivered in the second half of the year, and the lack of wind, especially in January and April.


Hydraulic electricity production dropped (-31.3%). In 2017, the hydroelectric parc produced a total of 173 GWh due to the low runoff for much of the year.
