While that is looking nice, (and I don't know how 'realtime' it is) it lacks the structure of the transmission nets, and the zoomability down to substation level in the towns/cities.
I can't remember exactly anymore, it didn't show every transformer in town, but the places where the high voltage overland transmission lines entered into town, and were transformed down to more managable levels were there. I think down to 10.000/50.000 Volts. That was different regionally. For instance Portugal vs. Germany.
