F150 is 98 kWh standard range, 131 extended. But the important point is this sentence:
Toyota explained that the system supports supplying power from hybrid electric vehicles
Presumably, this means you have a short, medium, and long option for emergency power:
- short: the battery
- medium: the battery + your car's battery
- long: use your ($25K) Prius as a gas generator to power your home for as long as necessary.
This seems like a more versatile setup than the e F150 at least for my use cases (rural WV -- power might be out for long periods but I can always get gas). It'll be interesting to see the price range of course, but this could be a good "mostly battery + gas if needed" backup option to compete with the diesel generator situation now. And of course the eF150 isn't really a good backup power (or transportation!) option in my case.
The eF150 generator use case always seemed like suburban prepper fantasy bullshit. The actual use case is for running power tools on site.

Perhaps you didn't hear about the millions of people who were miserable (and several who died) because their power grid is run by morons[1].
Losing power for three days may have been unusual for a long time, but with the combination of radical/unaccountable government, climate change, and aging energy infrastructure, it's easy to imagine that a lot of the warmer parts of the US are at some risk.
I’m planning for solar cells and looked into the possibility of running my house as a micro grid (ie disconnect it from the main grid) in case of a prolonged power outage. Turns out that unless you redneck engineer it, running your house without a main grid to synchronize to is very costly - among other things you need to supply your own grid grounding and that could easily run into the high €x000.
I already have a 2000W inverter wired to my Prius' 12v battery. Pop the car in ready mode and I can run things off it for ages, and then unplug them and go refuel the car if needed.
Having the extra storage battery mounted at my house would be cool and all I guess, but you don't need this to back up your house's power supply with a Prius.
(I live in a small, simple house and only run the blower fan for my propane heating system, my refrigerator, my freezer, and a lamp off the inverter. I suppose if you had much more complex power needs, the battery would be a larger advantage, but for emergency power outages, it keeps me from freezing or losing all my food.)
Running your home off your car's combustion engine sounds like exactly the wrong way around. I want a battery that allows me to save days worth of power from solar panels to use during cloudy days.

I think the Hybrid F150 / generator case is pretty decent; not so sure about the EV only generator one, but running tools could be useful. Rolling a truck over to my well when the power goes out will be a lot nicer than rolling out a portable generator by hand. Could be maybe useful for cell towers that rely on generators driven to the site during outages as well; although that depends on if they usually drop off a generator on a trailer and let it sit without local supervision or if they stay with the generator. My well servicing company has a box truck with a generator in the back, that they use to confirm that the problem isn't related to utility electric service; not sure if a built up f-150 would be sufficient for their storage/transport needs though.
Let me introduce you to the Eastern Seaboard and Gulf Coast of the United States of America, where people often run generators intermittently for weeks after a hurricane in order to keep their refrigerators and freezers cold until power can be fully restored.
I don't heat my home with electricity, and I am not home at the moment. Without lighting and cooking it does 4kwh/d.
When I am home and cook, wash and have the lights on I do about 7.
Factoring in the heating (Swedish "fjärrvärme", remote heating. Hot water from a central plant) I do A LOT more. Something like an extra 30kwh/d in the winter months for a 120 m2 home with half-decent insulation by Swedish standards.
I use around 70kWh/day (but nearly zero in summer and probably 4x that on colder days).
Heating is a heat pump with probably 300% efficiency (i.e. 3kW heat for 1kW electricity). Walls are 300mm insulated wood frame. Triple glass windows. -20C for at least one week every winter. Could probably lower the consumption by recycling more heat (none of the wastewater heat from hot water running down sinks is recycled for example).
Just to add a point as everybody is going on about how much they use per day or what: You are expected to generate power, too.
With a battery around 9 kWh, you'll probably install a solar system around 3 times as big or sth. like that.
So those capacity has to buffer for the night time when you're sleeping, heating probably goes somewhat down, nobody is cooking on 4 induction plates etc. pp.
I'm in a relatively small UK house. Selling power back to the grid doesn't get you lots of money these days, so the emphasis is on using batteries for night time use. Running off-grid isn't really something that is done, in urnban areas anyway.
Heating is gas, the hob is gas
I have 3kW panels and a 5KWh battery. During the summer hot water is heated through an immersion heater from solar - my electricity bill is roughly zero and I get to sell a bit back. During the winter - forget about it.
There is no reason for such comparison: the point of a small battery is ensure 24h full autonomy for critical loads (fridge, freezer, VMC if it's a new home, lights, computers etc. Batteries are NOT cheap so choosing to limit what's backed up is reasonable.
After, for far bigger backups, a vehicle might be a gamechanger: it need anyway a far bigger battery for it's own performance, so battery costs does not matter much for the use-case and using it once you own the battery...

Also the not-produced platinum model you reference will sell for 150k+ so the price comparison isn't really valid either.
Lastly, home batteries have the potential to pay for themselves over time, making the economic models radically different.
