Anyone who can find a spare $2k can buy one and quickly find they now have more than $2k spare, but you’d be amazed how many people, even in a rich part of the world like CA, don’t have as much spare cash as the average developer.

Like I said, “not zero, but…”
You just need to count the number of rooftop solar installations there are in the world to get an idea of the market size. Another $2k investment to get significantly more value out of an existing multithousand outlay would be a no brainer for most of them.
Mainly I’m expecting grid-corrected batteries of this type to be owned and operated by power companies and governments rather than by individual home owners; and most privately owned batteries to be the ones in cars rather than permanently attached to houses.
How explode-y is this battery? I hear California also has this problem with forest fires and it seems a fire and giant batteries all over the place would be two flavors that do not go well with each other.

> With so much oil-rich food on hand, including lard, cheese and more than 10 million pounds of surplus butter stored by the federal government, the fire was a hot mess — fast-moving, destructive and difficult to put out.
California, a state of 40 million people, would disagree with you ;)
Not just referencing the blackouts we had last summer: CA also is heavily invested in solar power, and as a result, power is much cheaper during the day than at night (assuming you opt into time of use pricing). A battery for $2k would pay for itself in California quickly, because you can charge it when power is cheap during the day and run off battery when power is expensive at night.
Plenty of other US states have had blackouts as well; my parents in PA now own a generator due to repeated blackouts last year. If they could have bought a battery for $2k, they probably would have: generators are loud and dirty. And Texans certainly had a bad time with blackouts recently as well.
