Products: n/a. Risk band: Elevated RobotRisk index 20.2/100 (incidents/exposure, time-weighted) · 99th percentile of 213 energy storage companies.
The record contains four entries spanning 2019-2022: two overheating malfunctions, one fire rated as well-managed by the vendor's own response team, and the 2019 APS McMicken explosion that injured four firefighters. Severity is mixed, with three moderate events and one severity-4 incident; there is no fatality on record. The index of 18.5 places Fluence at the 99.1 percentile within energy storage, indicating a concentration of documented events well above peers in the category. The pattern is press-driven, arising from grid-scale battery storage deployments rather than a single regulatory action, with the dominant failure mode being thermal/overheating events in large-format lithium installations. No incidents are recorded after 2022 in this data.
