I understand that people will adjust their consumption based on price, and I think that there are generally some interesting ideas with trying to fight the general logistical challenges of non-static demand through pricing. I think the core issue here (which is honestly my problem with surge pricing as well) is that there are limits in these systems. People in the cold need some heating, so no matter how high the price is there's going to be a floor of how much energy will be consumed. Peaker plants might exist, but there are only so many of those, so no matter how much demand there is supply can only vary by so much. Given those factors, it feels like the reasonable thing to do is to set price floors and ceilings that are "reasonable". If there needs to be exceptional pricing, honestly this is where the State can step in (and it can buy insurance or whatever for this) to help. But $9000/mwh isn't helping to relieve problems (especially when people don't even know!). Even in your cutoff knob, it's like... OK you are going to set a max price, and cut off your thing. Are you setting a max price for your fridge or your heating in winter? Or rather, would most people? Hell, what commercial enterprise is "shutting down the datacenter"? If we are going to say that pricing is a signal for controlling consumption, you need a feedback loop. That implies communicating price changes and giving people time to adjust for that. Generally this has been solved through the easy-to-understand "at these times it's cheaper" and "at these times it's more expensive". You can also have fun with seasonal variations as well. It's not 1-to-1 but hell, just charge more or less right and seasonally it should all average out nicely, and it doesn't require nearly as much futzing around. Market rate feedback could be done purely at the grid level, without exposing that to customers in real time, and mostly work. It removes arbitrage opportunities for energy providers, but that's a feature in my book.
