Who are the Players in the Belgian Energy Market?

Since the liberalization of the energy market in Belgium, there are 4 main actors in the industry:

  1. Energy suppliers
  2. Distribution Network Operators
  3. Transmission System Operators
  4. Regulators

The energy suppliers are the companies that will have direct contact with you over your supply of energy. The liberalization of the market allows you to choose which supplier you would like to take an energy contract with. From a consumer perspective, the purpose of the liberalization was to increase competition and provide more choices and innovation for the consumer.

The Distribution Supply Network Operators (DSOs) are in charge of distributing the supply from the transmission networks to your home.

The Transmission System Operators (TSOs) are in charge of the high pressure and high voltage transmission network from the energy sources, power plant or natural gas depot, throughout the country.

And finally, the regulators are in charge of overseeing the above players, and making sure that they all act within the frameworks of the law and in your best interest.

Operators of the Distribution and Transmission Supply Networks

Among the players in the energy market, are the operators of the distribution and transmission supply networks.

DSOs have a specific area where they distribute gas and electricity from the transmission network to your home.

With regard to the TSOs, they are responsible for maintaining the high voltage network for electricity, and the high pressure network for gas. They are notably in charge of transporting energy to DSOs and large industrial groups that need a large amount of energy.

In French, the Distribution Supply Network Operators (DSOs) are called gestionnaires du réseau de distribution (GRD), and the Transmission Supply Network Operators (TSO) are called gestionnaires du réseau de transport (GRT).
