I can run 10 old 100 watt light bulbs for an hour for 14 cents. Or 100 led light bulbs. I can run my hot tub full blast for an hour for $1.40. A head of lettuce is $4. A bag of coffee is $18. Five chicken breast is $20. A tank of gas for my wife’s car is $80, and for mine is over $200.
The cost of electricity for the loads I can control, such as those other heating or cooling living space, would have to 10x for it to be worth worrying about the cost, which would mean a $1400/MWH. The ceiling on the wholesale market price in ontario, last time I checked, was $2000/MWH.
I can see the price of electricity rising quite a bit across the board, but I don’t think people are going to inconvenience themselves at all to respond to it.

People already do that, and have done so for decades. Many places have different electricity costs for defined peak and off-peak times, and many people absolutely do move their heavy electricity uses outside the peak times when they can.
Naturally ymmv depending on your energy costs. And indeed other costs. ($4 for a lettuce sounds high, we pay pennies for that here.) It'll also vary depending on your overall income.
I would gracefully suggest that your life-style might not necessarily reflect the life style of the general public?
it sounds like british columbia grocery prices are insane. are those us dollars? five chicken breasts here is about $3000, which is about 2½ us dollars
aha, thanks. xe tells me those are 27% smaller than us dollars, so those prices are respectively 1 dollar, 3 dollars, 13 dollars, 15 dollars, 58 dollars, and 150 dollars, speaking in us dollars
or, using today's mid-market rates from https://preciodolarblue.com.ar/, $1300, $3800, $17000, $19000, $75000, and $190000. $19000 is sure a lot more than i'd pay for five chicken breasts
as a clarification from further down the thread, since you said those are canadian dollars, those prices are respectively 1 dollar, 3 dollars, 13 dollars, 15 dollars, 58 dollars, and 150 dollars, speaking in us dollars
me, i pay $3000 for five chicken breasts, which is about 2.3 us dollars
What if I'd want to warn users that the list really only encompasses sports related domains? Genuinely want to follow the etiquette here, but I like being useful.
Tesla will come to the utility and say we can offer you 3000 MW of demand response in any granularity you want for $x/hr.
$x is usually not very big since the modus operandi for the bulk electric system in North America has been everyone can use as much power as they want whenever they want, so we have had lots of supply.
But a couple of times per year $x could be thousands of dollars per MW per hour, for a few hours. So not worth the effort really.
Maybe Tesla will offer the demand response more geographically so distribution utilities can also use it for peak shaving on their substations. But that is pretty brave area to be operating in for a utility, depending on Tesla to avoid overloading transformers or risk a localized black out.
There would have to be a serious penalty for bidding in the demand response but then not performing as well.
I agree it does seem far fetched at this time.
Edit: price signals to consumers is probably a better mechanism
Space, cost, reliability, of course it's complex to integrate new generators that require communications to work together properly alongside planning the real wire infrastructure.
I believe it can be done, sure, but it's still complex and utility companies are not a fan of complexity.
I'm not defending the idea of using two out-of-phase 110V circuits, but... this theoretical EVSE could detect its two inputs not being out-of-phase, blink its red "110V only" light, and only use one of the inputs to charge at 110V instead of 220V.
Any source can be disconnected from the bulk electric system. If there is too much power and a generator is told to disconnect it is called a curtailment. Some contracts allow the generator to get paid for the power they could have produced but weren’t allowed to deliver due to too much supply / not enough load, so it isn’t really a good thing as the ratepayers still end up paying for the power not generated.
Dispatchable generally means you can tell the source when to generate as opposed to when not to.
I’ve had good results deploying both wind and solar at remote off grid sites, when there was a week of clouds due to a storm system moving through there was quite often a lot of wind and the batteries would stay fully charged.
what kind of hardware do you use to capture wind energy? It’s pretty easy to get into solar as a hobbyist but wind seems to have a higher barrier to entry (?)
Some $300 wind turbines off Ali baba that put out 300 watts or something. It was kind of like a propeller diameter 1m mounted to a little dc motor that was mostly bearings.
We mounted it on a pile to a shed made of metal covered foam panels, the whole shed blew over. Guyed it down after that.
Maybe 1m was the radius, this project was more than 15 years ago. The point was instead of dead batteries during cloudy times the wind complemented nicely and the batteries were charged and our load powered.
