Kolkata: Metro Railway To Install Batteries To Rescue Trains During Power Outages On Blue Line

The Metro Railway is set to introduce a Battery Energy Storage System (BESS) on the Blue Line to keep trains running during power failures. The BESS combines inverters and advanced lithium iron phosphate batteries, allowing stranded trains to travel to the nearest station at 30 km/hr during power cuts. This system is part of the National Programme on Advanced Chemistry Cell battery storage, approved with a budget of Rs 18,100 crore. The Metro Railway will be the first in Indian Railways to use this system, with plans to install a total of seven BESS units. The first unit, with a capacity of 4MW, is expected to be operational by the end of the year. LiFePO4 batteries used in the BESS are more efficient, safer, and cost-effective, storing energy for peak-hour demand and reducing energy costs.
