Kolkata Metro adds battery power for safety
26 Feb
Summary
- Kolkata Metro's Blue Line now uses a Battery Energy Storage System.
- The 4 MW BESS uses a 6.4 MWh Lithium Iron Phosphate battery.
- It ensures passenger safety and handles power demand spikes.
Kolkata Metro Railway has implemented a groundbreaking Battery Energy Storage System (BESS) along the underground stretch of its Blue Line, a significant first for Indian Railways. This advanced system is designed to bolster energy efficiency and bolster passenger safety during unexpected power outages.
The 4 MW BESS utilizes a 6.4 MWh Lithium Iron Phosphate battery. If a grid failure occurs, this system can provide stored power to haul metro rakes to the nearest station at a speed of 55 km/hr. Furthermore, it ensures continuous operation of tunnel ventilation and environmental control systems at underground stations.
This innovative BESS is also set to improve the power factor, leading to reduced energy bills and efficient handling of sudden power demand surges. With a lifespan of approximately 14 years and a compact design, the system, which is equipped with green batteries, signifies a step towards a reduced carbon footprint compared to conventional generators.
