For anyone else curious, MWe stands for "megawatt electric". The average American home uses very roughly 1000 watts on average [0], so a 500 MWe plant serves very roughly 500,000 American homes.

901,000 watt-hours per month / (30 * 24) ~= 1,250 watts

An average isn't very helpful here. A single kettle / oven / heater will use 1 kW by itself.

Not every house will have one of those on at all times. Sure, a house could use many multiples more than 1 kW for a bit, but will go back down eventually.

Yes, that's why an average isn't too meaningful. The times these things are on aren't the same for every house, but they are correlated.
