Luminus : a Supplier of Green Energy


Luminus is one of the largest suppliers of gas and electricity in Belgium. Bought by EDF in 2011, the supplier relies on renewable energy and aims to become the preferred energy supplier of the Belgians and residents of Belgium.

Luminus’ History

Already present as a supplier in the Flemish market, Luminus is gaining importance and market share following the liberalization of the energy market in Wallonia. In fact, Luminus merged with SPE in the 2000s, a public electricity production company founded in 1978.

In 2009, EDF took a majority stake in the company, then fully bought SPE-Luminus in 2011. This is how the name EDF Luminus appeared on the scene, but the company retains the Luminus brand name for its activities in Belgium.

In addition to providing green and gray electricity and natural gas, Luminus offers its customers a range of services and products related to solar panels, water heaters and home help in the event of power outages and the likes.

They use environmentally friendly technologies and renewable energy sources such as:

  4. Solar energy
