Who are we ?

DNB BA is the operator of the closed distribution grid of Brussels Airport. We are responsible for the electricity distribution on the Brussels Airport site. So we do not supply electricity, but transport it from the high-voltage grid to the individual installations. Companies on the Brussels Airport site choose their electricity supplier themselves.

What is a distribution system operator?

• is responsible for the transport and distribution of electricity from the high-voltage grid to the individual installations
• is responsible for the commissioning/decommissioning of connections, placing of electricity meters, recording of meter readings, etc.
• does the maintenance and development to keep the distribution grid safe and reliable
• has a regulated monopoly on their territory

A distribution system operator is only responsible for the transport and distribution of the energy purchased by the end user and is therefore not an energy supplier. Companies such as Elia Fluvius, Ores and Sibelga are public grid operators which are regulated by federal and regional regulators such as CREG and VREG, CWaPE and Brugel.

What is a closed distribution grid?

• An electricity grid in a geographically defined zone
• Industrial or commercial location, or location with shared services
• No domestic customers
• The owner of the grid is also the main contractor

The Brussels Airport site meets these European defined conditions. That is why DNB BA was qualified by the Flemish regulator VREG in 2012 as the operator of a closed distribution grid. Companies on the Brussels Airport site can therefore choose their electricity supplier themselves.

The role of DNB BA as operator of the closed distribution grid of Brussels Airport

DNB BA is responsible for the developement and operation the closed electricity distribution system in the Brussels Airport area.

The closed distribution grid consists of:

• 2 injection points of 36kV on the Elia transmission grid;
• Transformers that convert the high voltage to 11kV to 400V
• Cabins that distribute the electricity to the end users
• Meters that measure electricity consumption
• High or low voltage cables that transport electricity.
• IT and communication tools.

For our clients we want to play the role of reliable advisor and partner with the aim of developing and operating the Brussels Airport distribution grid according to the “Best Practices”, norms and regulations in a non-discriminatory way for the entire Airport Community. For the Belgian energy market, we also have the responsibility to communicate correct consumption data.
