Products: bess-oem, battery-pack. Risk band: Elevated RobotRisk index 25.0/100 (incidents/exposure, time-weighted) · 100th percentile of 213 energy storage companies.
The record contains three entries over roughly two months: a September 2025 Australian Powerwall 2 recall for overheating/fire risk, a September 2025 Megapack fire burning for hours at a Nevada solar facility, and a November 2025 US Powerwall 2 AC recall for fire/burn risk. All three entries carry severity 3, giving the record a uniform severity profile without escalation. The record mixes regulator-driven action (two recalls) with a press-reported operational fire, indicating both battery-system and grid-scale storage products are implicated. Tesla Energy's index of 26.4 places it at the 99.5th percentile of the energy-storage category, the highest standing in this dataset, reflecting recurrence across distinct incident types rather than a single event.
