There's live stats for the UK's national grid. There's a couple of sites that show it, e.g. http://gridwatch.co.uk/ http://gridwatch.co.uk/ Really interesting to see. Britain also has the interesting culture of tea drinking in the evenings - almost all using electric kettles. I believe the grid uses hydro stations to cover the load of this. Typically peaks during breaks and/or after popular TV shows in the evening.
