Flood, cyclones, heavy rains and thunderstorm pose multiple and interconnected risks to the e-bus ecosystem affecting fleet, depots, charging infrastructure, and the operating environment simultaneously. Key risks include water ingress into batteries, traction motors and electronic system leading to vehicle damage and safety hazards. Substation and chargers are vulnerable to flooding and power outages, disrupting charging operations. Depots face risks such as inundation of parking bays, workshop and control room, along with access blockages during extreme weather events. Strong wind can cause structural damage, while flooded or unsafe roads result in service disruption and delays.
Explore the expandable sections to see detailed preventive, responsive and recovery measures for the Flood/ Cyclone/ Heavy Rains/ Thunderstorm hazard and for each component (Fleet, Depot, Charging Infrastructure & Operating Environment).
