Tata Power, a leading Indian power company, has received approval from the Maharashtra Electricity Regulatory Commission (MERC) to install a 100 MW battery energy storage system (BESS) in Mumbai. The system will be installed across ten strategically located sites across the city, with central monitoring and control from Tata Power’s Power System Control Center.
The BESS will enable a fast recovery of power supply to critical infrastructure, such as the metro, hospitals, airport, and data centers, in the event of grid disturbances. This will prevent large-scale blackouts and enhance the city’s power network resilience. Additionally, the system will facilitate peak load management by providing a stable and balanced power supply during high-demand periods.
The BESS will also offer ancillary services, including frequency regulation and voltage support, to strengthen grid stability. Furthermore, it will enable better utilization of solar energy by storing surplus daytime power and making it available during peak demand, ensuring optimal renewable energy integration.
The system will be designed with advanced features, including three layers of temperature monitoring and fire suppression systems to reduce the risks of fire hazards. It will have high round-trip efficiency with reduced auxiliary consumption, enhancing operational performance and extending the storage system’s lifespan.
Tata Power is a diversified power company with a portfolio of 15.6 GW, including renewable and conventional energy generation, transmission, distribution, trading, storage solutions, and solar cell and module manufacturing. Clean energy generation accounts for 43% (6.7 GW) of its total capacity.
The installation of the BESS is expected to be completed over the next two years. Future plans include integrating the system into the Distributed Energy Resource Management System to enhance operational efficiency.
