With places that have time-of-day rates, I wonder what will happen when enough systems get advanced enough to precisely kick-off/on (or slow down/speed up) in unison at precise times.

I’ve set this up on my “smart” thermostat to speed up just before rates go up and kick off for a while once they do (and it was a pain to setup, somehow this functionality was not baked in)

In the UK, the grid used to have to manage the load when millions of people would all put the kettle on during popular TV advertisement breaks.
