Currently every power plant runs at about 20% capacity overnight. If EVs are charged on timers they don’t need anything more than the existing spare capacity.

I don't know if that's true. especially on summer nights.

But beyond that, power plants need energy sources to generate electricity. Your response doesn't address that.

Most EV'ers don't.

“But beyond that, power plants need energy sources to generate electricity. Your response doesn’t address that.”

Correct, the move to EVs might not required new powerplants, but each of them will have to burn a lot more fuel. Today in the US that will cause a large increase in demand for natural gas.
