Power generation

In collaboration with FEBEG, Elia makes generation data available in a uniform and transparent way.

In November 2006, the members of generators’ association FEBEG (Belgian Federation of Electricity and Gas Enterprises) launched a voluntary initiative, in collaboration with Elia, aimed at gradually increasing publications concerning generation units. This initiative allows information to be published in a uniform and transparent way and on a neutral website for all market players.

To find out more about this voluntary initiative and the associated publications, click on the procedure for publishing power generation data.

Data relating to generation units

The operational data related to production forecasts and generation units for which a CIPU contract (Contract for the Injection of Production Units) has been signed with Elia, are organised as follows:

  • generating facilities and installed capacity;
  • wind-power generation
  • solar-PV power generation
  • available generation capacity forecasts;
  • generation schedule;
  • unplanned outages of generation units and the changes in the scheduled unavailability planning of generation units;
  • generated energy;
  • forecast evolution of the generation capacity.


Fuel types

In most publications, the data are aggregated by fuel type. The seven types of fuel included in the publications are:

  • nuclear (NU);
  • coal (CP);
  • gas (NG);
  • liquid fuel (LF);
  • water, it includes Run of River power plants and pumping facilities (WA);
  • wind (WI);
  • ‘other’, including waste, biomass, blast furnace gas, photovoltaic, etc.

In the case of multiple-fuel generation units, the data are grouped under the fuel that was used most in the previous year (e.g. if the primary sources were 20% gas, 35% coal and 45% blast furnace gas, the ‘Other’ category will be used).
