Luminus is one of the biggest energy suppliers in Belgium and also an important producer of electricity. On this page you will find all the information about Luminus, such as the current offers and how to contact the customer service.
Who is Luminus in Belgium?
Luminus originated from the public company SPE. SPE was founded in 1978 as an intermunicipal company to regroup the power stations in public hands. This included the electricity producers of the city of Liège, the West Flemish electricity company and the power plant of the city of Ghent.
SPE also acquired a share in Belgian nuclear power plants and integrated itself in the 1990s with the then monopolist Electrabel.
After the liberalisation of the Belgian energy market in 2003, minority shareholder EDF (which had a monopoly on the supply of electricity in France) increased its share. The company's nuclear capacity also continued to grow slowly but surely. In 2011 the name was changed to EDF Luminus.
How many customers does Luminus have?
Luminus has grown quickly after the liberalisation of the Belgian energy market. In the first quarter of 2023, Luminus had a market share in Flanders of 24,06% on the electricity market and 23,72% on the gas market. This makes Luminus the second largest provider in Belgium, just after ENGIE and before Eneco.
