Hourly unitwise historical generation data in Europe

dataset

#1

Does anyone know alternative sources to
(1) ENTSO-E’s Transparency Platform or
(2) EEX Transparency
when it comes to hourly historical generation/production data for power plants in Europe?
The problem with the former is that there seem to be gaps in the data, while the latter only covers (a) nine countries and (b) only units at or above 100 MW. This leads to the fact that both sources deviate from countrywise statistics.

Thanks! Fabian
