Everything you're saying is wrong.

We only have a stable grid now because the hottest days produce the most solar to power ac. Our grid would have collapsed otherwise .

In the past we had huge demand swings during the course of a single day, as factories and offices burned power, then people went home to cook food and run their laundry.

Solar helped that greatly, coupled with fracking gas which allowed us to plant ge90 turbines everywhere for nothing and have we extremely dispatchable power for load following.

Especially since bulbs went led and now might generation is much more manageable.

But mentally defective utilities can't do the sane thing and write an API so that EV's can coordinate charging to balance load.

The problem with utilities is that they're stuffed to the gills with the idiot relatives of politicians who couldn't get jobs anywhere else.
