Import dependence

Definitions

Import dependence: share of net imports in primary energy consumption. This primary energy consumption is the amount of energy that a geographical entity needs in order to be able to meet the demand for energy during the observed period and is the sum of the primary energy production and the net imports of energy.


Remarks on quality

Compiling the energy balance is one of the reference tasks of the Flemish Institute for Technological Research (VITO). The aim is to provide a complete overview of the energy consumption in Flanders in a given year in a single report and to monitor the evolution of this energy consumption. 

An energy balance coherently presents an inventory of the energy flows in a given year and for a given geographical area. The most commonly used format for mapping energy flows and energy data for a given area is an energy balance that lists all flows (stocks, productions, imports, exports, consumption) for each energy carrier.

In Flanders, we ensure that the energy balance is in balance through our own means because certain figures are not available at the Flemish level. Flemish net import is not known and is calculated for most energy carriers as being the gross domestic energy consumption + bunkers - primary production. The primary production in Flanders is limited to electricity production from wind, hydropower and PV installations and a calculated value for other fuels, biomass and heat. In the case of other fuels and heat, the energy balance is brought in balance through the assumption that the net import is equal to 0 and that the total internal consumption is 'produced' in Flanders. In the case of biomass, the energy balance is brought in balance by dividing it between 'net imports' and 'primary production' on the basis of available information on the origin of biomass. Since Flanders is the only region bordering the sea, the Flemish maritime bunkers are considered to be equal to those of Belgium.

The figures on the energy balance for past years may change every year, if better or more detailed data are obtained or through changes in methodology.
