I have researched that project before. It’s a typical Musk (not a fan) vanity project, no one has any idea of the total costs or lifecycle implications of it.
I deal with 'Uninterruptable Power Supplies' (UPS) systems in hospitals, it is a glorified battery back-up system for when power goes down and before the diesel generators kick in, it is to guard against that vital few seconds in between so operations don’t into darkness, etc. The costs of these things are off the scale, I’m not fibbing when I say the costs (when all lifecycle implications are taken into account) are many, many multiples of the diesel generation back up, which is in itself multiples of the off the grid costs. Know one would go near it if it wasn't for critical for life safety issues.
They are years or commercial viability, namely, because the battery degrades so damn quickly and then they need to be kept in very cool conditions which then needs air cooling systems at huge costs!!
They are years off from being in a place where large scale grids can use them.
