It's probably an additional $3-6K on top of the smart meter to build in such switching (an ATS and a control system to understand the current/projected rate and switch based on it). For this event, going down to your main panel and flipping the main breaker for a few days would have accomplished the same thing for no cost.
I suspect the same people who bought Griddy's save money almost all the time plan are not the ones likely to install $5K of extra switching equipment at their house to protect themselves from a multi-day deep freeze event in Texas. Certainly no landlord is going to install that where they bear the costs and maintenance so their tenants can buy cheaper electricity.
For example just by heating and cooling houses a few hours before people get home, we can shift a lot of demand towards the middle of the day when solar power is abundant, and away from evening peaks.
We're definitely going to need something like this for widespread EV usage, where cars can potentially upload power to the grid.
Government has a role here in setting standards. They are the ones who get blamed for high energy prices or outages, anyway.
These guys used to do this in NYC.... would let ConEd turn off your AC in the middle of the summer
(Under the hood it's an IOT zigbee hub)
I think the right regulatory approach this case would be to require the purchaser to manage their risk so that you can shop around like we do with other insurances. So if you go with a retail electric company you don't have to worry since you're not the purchaser.
It's why people buy products and services rather than vertically integrate everything in their lives. I don't want to live Texan Power Simulator any more than I want to be mining my own bauxite or replacing my driveway. Buying a product or service is granting the supplier a profit in exchange for them worrying about and executing the business. But you don't buy power any more. You buy access to a dynamic marketplace in which you probably didn't really want to participate.
What if there were real time pricing per byte coming down from your ISP and you had to sit and stare at your screen waiting for an affordable moment to check your email? Or what if you had to stop mid-shower to avoid spending five figures to rinse the soap off? I can't imagine being happy in those cases, I don't know why I should be happy about it for electricity.
You're on to an idea that the article doesn't cover: If you want consumers to constrain their utilization during periods of high demand without using price shifts, you might require they install suitably "smart" thermostats and appliances along with their smart meter. These could allow the utility to forcibly curtail power use without rolling blackouts. Some utilities already offer a softer version of this, with your Nest offering to tweak your schedule to marginally lower your bill.
Of course that kind of invasive control would likely not go over much better than $16,000 power bills.
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.
Unfortunately, that's a terrible option too. The cold is survivable with some gear, but your pipes will freeze and burst unless you drain them (which I have no idea how to do, if it can be done).
We also had several deaths due to people using gas heaters indoors. I think it releases carbon monoxide? Not entirely sure, but those outdoor heaters are meant to be outdoors.
It's possible it might be doable with a user override.
Where do you draw the line? "Griddy, please turn my power off if the price goes above $1/kwh"... "Griddy, please turn the power off if I forget to pay the bill.", "Griddy, I'll take a $10/month discount if the power gets turned off when my bill is paid late?", "Griddy, I want to use non-ripoff plan, so I'm happy for you to turn my power off the minute I pay late".
See how it isn't really feasible to stop power companies forcibly illegally disconnecting debtors if you allow a debtor to agree to be disconnected voluntarily?
Traditionally they sent a technician out to read each meter and turn off the electricity if necessary, but there are newer "smart meters" that communicate your usage to the power company (although I'm not sure if those can also be remotely triggered to turn off your power, I would suspect not).
Where I grew up in a small town in the Midwestern US in the 1990s, the meters were usually installed on an external wall at the back of the house. My part of town had underground power lines (good during thunderstorms, bad during road/building construction) and I suspect the meter was right where the buried cable came into the house. Every month a uniformed person from the power company would walk through everyone's backyards taking the reading from each meter.
Fun fact: most utilities and similar services have historically worked this way. I think the cable television company would just send someone to the cable box on the back of your house and flip switches to enable the channels you were paying for. There was always some kid who claimed to get HBO for free because his older cousin worked for the cable company.
Now that I think about it, I recently got a car that's new enough to have Sirius XM satellite radio built in, and I've been wondering how their access control works. Surely the satellite doesn't beam down everyone's subscription status and make their receiver hardware respect that, right? Is my car using the built-in cell phone to check whether I'm subscribed to the satellite radio? Either way, where are the bootlegged satellite radio receivers?
- The stream channels themselves are encrypted or scrambled in a way that is hard to unwind unless you have the keys (keeping non-SiriusXM radios from working)
- Each radio has two important pieces of information: a decryption key from SiriusXM and a UUID (I'd guess 64bit, as that's a pretty standard size for hardware-baked-in UUIDs. It might be 128bit instead). You can look up the UUID for your radio. Both of those things, by the way, are bog-standard now in consumer embedded systems exactly because they help prevent bootlegging.
- Channel 0 is an ID channel that constantly streams out a list of valid UUIDs and other configuration data. An un-activated radio can only tune that channel. When it sees its own ID, it enables the rest of the channels.
Quick sanity check: Assuming they have 40 million subscribers and can pass UUIDs at roughly audio rate (to make the math easy, 16-bit, 50kHz), that makes it about an hour to sync all the users. That can probably be watched by your radio in the background, so it's only an issue for initial activation.
Satellite bandwidth is expensive... Activation time is annoying for customers... The above scheme saves either (or both).
Looking at teardowns of the current Onyx radio [0], the NXP LPC4078FET180 has both a unique ID and some mechanisms to make it very difficult to read the programmed code externally. One option would be to store the key there, and use that mcu to run all the audio decryption, processing, device activation, and protocol updates (under the control of the TMX570 running the UI etc).

I think these regulations came into place after people died due to the cold, or died because they needed their oxygen generator and power was cut. Possibly the regulations were proactive.
I worked with a company that built prepay power systems that communicated by modem, and cut the power when the money ran out... except when the regulations (mostly sensible rules) kicked in to prevent harm.
In New Zealand there is also a ripple control system to shed domestic loads during peak demand (mostly hot water cylinders).
SDG&E, in California, offers such a plan (layered on top of conventional TOU terms).
That way, those who would rather get through a blackout without paying insane bills can have an option to do so, while those who care about their pipes freezing can pay to keep the electricity.
