GM will also sell stationary storage to enable V2H capabilities.
I own a Chevy Volt, and it's great. But I don't think the battery is going to power my A/C for more than an hour.
Chevy Volt according to Wikipedia has something like 16.5 kWh.
I don't know how big your house/flat is and for how much power your AC unit is rated for, but it should be enough for at least 3-5 hours under a full load for a rather powerful multi split AC unit.
If you keep in mind that AC doesn't draw full power to keep an already cool room cool, your car might be just enough to keep the AC running through the night or majority of daylight hours.
The smarter move would be during an emergency to get everybody into the Volt and let it cool that smaller space. It won’t be as comfortable, but the battery would likely get you through the whole night at a decent temperature.

-You, probably
A quick Google search says a central A/C unit takes about 3 kilowatts to run. The Volt has a 16 kWH battery, about 11 usable, so you'd get a few hours out of a charge.
That said, the Volt is a hybrid. Its battery is relatively small because you're carrying a gas engine and can go farther if you need it. My Bolt's battery isn't huge compared to some cars coming out, and its battery is about 65 kWH. Should be enough to power a house for about a day, and it only gets better from there.
The Volt also contains a gasoline-powered generator, which would be really useful if you could connect it to your house.
Biggest use-case for this is during extended power incidents where you need to keep your fridge cold, run fans during hot days, and allow for hot meal prep if you have a plug-in burner.
There are tons of hummer EVs in my city, I see at least 2-3 daily. But you’re also not buying a house for anywhere near 100,000 in my city unless it was a meth manufacturing facility right before you bought it
People who can use IRS section 179.
Lets you write off the whole car as depreciation in year 1.
Wow 3 years to power the house is a little slow. They should consider upping up the voltage.
I wouldn't be surprised if this eventually became law. EVs helping to balance the whole electrical grid would be a massive infrastructure boost.
How would such a use affect the car batteries? Ideally you'd use different batteries for fixed installations than cars, as weight is less of a concern than longevity ; a car sitting idle like 70-80% of a day sees way less battery activity than a home panel, which should be charged/discharged more constantly.
it's not really a feature you'd use at home except to power essential items during a power outage. so maybe they're looking at marketing these mostly in Texas.
