It's an avenue that should be pursued if a state truly wants to have market-based pricing. For that to work there definitely needs to be transparency and ways for customers to easily automatically adjust in response to pricing signals. Though it could be pricy, there is plenty of promising tech approaches and it could definitely be part of an overall more efficient grid.

For example, Tesla Powerwalls (disclaimer: I've got a few) already allow custom time-based controls precisely for the purpose of saving money when on a utility plan that is split into peak/shoulder/off-peak pricing. That's one of the ways they can offer some direct financial return (benefits from generator replacement and on-site production aside). That's not granular enough or automated enough to react to a situation like this one, but on the face of it doesn't seem like any reason it couldn't be. If Tesla had an API that someone like Griddy could talk to, an interface in the app for something like "price-based control" seems like it'd be doable and an interesting value-add and a relatively low lift. Powerwalls already have remote control functionality for grid-operator/customer deals. And it'd give a lot more buffer.

However those of course are $6.5k a pop right now. Long term it might be more fruitful for many people to lean on future electric vehicles for this. Those have humongous batteries and alternate ROI so a lot of people may ultimately have them anyway, vs being a dedicated expense. Hopefully the next decade, along with more fundamental grid investment period, will also see the natural spread of more and smarter buffering options.
