What can be learned from grid-scale battery fires?
Battery fires, while a rare occurrence given the number of lithium-ion batteries manufactured and deployed each year, are common enough to worry insurers and others in the industry. Following high-profile battery fires in 2024 and 2025, the industry is busy implementing solutions not only to reduce the risk of fire breaking out in the first place, but to contain and mitigate the risk of injury or damage should it happen. Conclusions from large-scale fire testing will be key.
