Understand your bill by understanding the energy market

Belgium’s energy market has been liberalised. Customers are free to pick whichever energy supplier they wish. Liberalisation opened the door to multiple players on the market. ENGIE Electrabel is present there as an energy producer and supplier to the consumer.


The energy component only accounts for 20 to 30% of the bill

Breaking down your energy bill

Although energy only accounts for 20 to 30% of the electricity bill, the supplier (e.g. ENGIE Electrabel) must charge the end customer for all costs incurred by the various bill items (energy, transmission, distribution, taxes).

The players on the liberalised energy market


  1. The producers
    Using a range of technologies, the producers generate electricity in Belgium or abroad. This electricity is then injected onto the grid. ENGIE Electrabel, Belgium’s largest electricity producer, generates energy locally, close to its customers.
  2. The transmission system operator
    In Belgium, Elia is responsible for transmitting electricity via the high-voltage grid from power plants to major industrial consumers and distribution systems. Elia manages the high-voltage grid while maintaining a constant balance between electricity supply and demand. Fluxys is in charge of the natural gas transmission system and storage facilities.
  3. The distribution system operators
    The distribution system operators distribute electricity (and gas) to end consumers via the low and medium-voltage grid. They are also responsible for enhancing and maintaining the grid, connections and meter readings. These tasks are primarily performed by Eandis and Infrax (Flanders), Ores (Wallonia) and Sibelga (Brussels).
  4. The suppliers
    The suppliers either buy electricity and gas on an energy market and then sell it on or, like ENGIE Electrabel, generate it themselves and sell it to their customers. The supplier is also the end customer’s point of contact.
  5. Governments and regulators
    Governments define the energy policy for countries and regions.
    Regulators check the players on the market and guarantee that they adhere to standards. Belgium’s regulators are CREG (Federal level), VREG (Flanders), CWaPE (Wallonia) and Brugel (Brussels).
  6. The customers
    Private individuals, businesses and public authorities are free to pick their electricity supplier. The Belgian market is very competitive. Customers can also sometimes generate their own energy if they have a photovoltaic, wind power or cogeneration facility, for example.
