The MERRA2 reanalysis data (1980-2018) 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 current situation (2017). In addition a corresponding daily time series of nationally aggregated electricity demand is provided. The data sets have been produced to investigate the inter-annual variability of the three weather-dependent power system components
