Wind energy (gross production), normalised

Normalised gross production of electricity from wind energy, calculated according to definitions from the EU Renewable Energy Directive. The aim is to correct production for changes in weather conditions and thus neutralise fluctuations in wind supply. Normalised production for all wind energy in the Netherlands in a given reporting year is calculated as follows: the average of the capacity at the beginning and end of a reporting year multiplied by the average production per unit of capacity over the past five years. As of reporting year 2021, this calculation is done separately for onshore and offshore wind.
