This is why you don’t use battery chemistries that can thermally run away autoignite in grid storage. The plant was using LG JH4 batteries, which use an NMC chemistry. I don’t think that LiFePO4 cells were as ubiquitous when this plant was first constructed, so the designers opted for something spicy instead.
This shit is why you use LiFePO4. It can’t thermally run away autoignite, it lasts longer, and the reduced energy density doesn’t really matter for grid storage. Plus, it doesn’t use nickel or cobalt so the only conflict resource is lithium.
EDIT: LiFePO4 batteries can enter thermal runaway, but they can’t autoignite.
