ERA5 derived time series of European country-aggregate electricity demand, wind power generation and solar power generation: hourly data from 1979-2019

ERA5 derived time series of European country-aggregate electricity demand, wind power generation and solar power generation: hourly data from 1979-2019.  The ERA5 reanalysis data (1979-2019) has been used to calculate the hourly country aggregated wind and solar power generation for 28 European countries based on a distribution of wind and solar farms which is considered to be representative of the 2017 situation. In addition a corresponding daily time series of nationally aggregated electricity demand is provided. The datasets have been produced to investigate the inter-annual variability of the three weather-dependent power system components. The dataset  here is an ERA5-derived time series of European country-aggregate elec-tricity wind power generation (Bloomfield et al., 2020). The authors use the ERA5 reanalysis data(Hersbach et al., 2020) to compute the nationally aggregated hourly capacity factor of 28 Europeancountries between 1979 and 2019. The capacity factor of a wind turbine is the ratio of the electricalenergy produced by the turbine for the period of time considered to the total amount of electricalenergy that could have been produced at full power operation during the same period.
