> *500 GWh of electricity every hour* GWh/h, or simply 500 GW ;)

Not quite the same thing. Watts are power. Watt-hours per hour (or jules per hour) are average energy consumption during one hour.

Yes, but in practice Watts are almost always an average over some sample period. Generation capacities for power plants are given in Watts, not Wh/h. Wh/h gives you a hint that the sample period was an hour, but that isn't necessarily the case. I don't think Wh/h is the correct way to describe the sample period.
