Fluence

Robot types: Battery energy storage system. Risk band: Elevated   RobotRisk index 31.7/100 (severity- and time-weighted incidents) · ranked 3 of 7 among Energy storage companies with incidents (682 tracked).

Analyst brief

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 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.
