<<Ah, but your utility certainly has “peak costs” and “off peak costs”. They just haven’t bothered to unbundle it so you could get a peek behind the curtain. Every utility has base-load, generation which doesn’t change easily: hydro from dams, or perhaps electrons from nuclear. But there are intermediate load sources like coal plants and peak load sources like gas turbines, and all that has to be balanced against demand, because too little and your home goes dark. Too much and they fry their transformers. It costs money to scale up - and start up - and bring down those intermediate and peak load generators, which is why they don’t run overnight or in other low demand times.>>

EV would be a great balancer to peak and off-peak demands. One more reason for electricity producer and the nation as a whole to promote EVs.
