Tata Power to install 100 MW Battery Energy Storage System in Mumbai
Apr-07-2025

Tata Power Company has received approval from the Maharashtra Electricity Regulatory Commission (MERC) to install a 100 MW Battery Energy Storage System (BESS) in Mumbai over the next two years. The BESS, equipped with advanced 'black start' functionality, will enable a swift recovery of power supply to critical infrastructure, including the metro, hospitals, Airport, and Data Centers, in case of grid disturbances. This will prevent large-scale blackouts and enhance Mumbai’s power network resilience. Additionally, the system’s sophisticated technology will optimize reactive power management, improving peak demand efficiency and strengthening the city's power infrastructure. 

With high ramp-rate capability, the BESS will facilitate peak load management, ensuring a stable and balanced power supply even during high-demand periods. It will also help reduce power purchase costs by storing energy during low-cost periods and utilizing it during high-cost peak hours thereby ensuring reduced tariffs for consumers in the future. Furthermore, the BESS will support capital expenditure (capex) deferral by minimizing the need for costly infrastructure upgrades and efficiently managing load fluctuations with stored energy.

Tata Power Company is India’s largest integrated power company. It is a pioneer credited with steering the energy sector on technology, process and platform.
