ENTSO-E hourly load time series for European countries
The European Network of Transmission System Operators for Electricity, ENTSOE-E, hold hourly demand data for each EU country. Their terms and conditions do not allow redistribution. It may be worth our while putting in a single, co-ordinated request to cover access to and redistribution of the archive.

system data such as power plants and load, wind and solar time series.
Elexon time series for Great Britain
Elexon manages the data for the GB network, and this is available half-hourly. Registration is free.

There are also several different variations of total demand available from the GB National Grid, also all half-hourly
