Kolkata Metro Railway is set to introduce a battery energy storage system (BESS) to ensure seamless train operations during power outages. This innovative system, which combines inverters and advanced lithium iron phosphate (LiFePO4) batteries, will be installed at the Central station sub-station.
The BESS will enable trains to travel at 30 km/hour to the nearest station during power failures, minimising inconvenience for passengers stranded in tunnels or on elevated tracks.
The shortest distance between stations on this line is about 700 metres, with the longest stretch exceeding 2 km.
