The installations form part of Tata Power’s broader strategy to modernise Mumbai’s electricity infrastructure and strengthen the resilience of the city’s power network.
Tata Power has deployed 60 MWh of battery energy storage systems (BESS) across Mumbai to strengthen grid reliability, improve power procurement efficiency and support peak-demand management across its electricity distribution network serving more than 800,000 consumers.
The battery storage installations, located in Mahalaxmi, Saki and Mankhurd, are designed to enhance the flexibility and resilience of the city’s power network by storing electricity during lower-cost periods and discharging it during peak demand hours.
“The systems enable more efficient utilisation of energy, optimise power purchase costs and reduce reliance on expensive peak-hour electricity. Equipped with fast-response and high ramp-rate capabilities, the installations can respond rapidly to fluctuations in demand and support dynamic load management across the distribution network,” Tata Power, one of India’s largest integrated power companies, said in a statement.
Operating at approximately one to one-and-a-half charge-discharge cycles per day, the storage systems support peak-load optimisation and improve power procurement efficiency. Their decentralised, grid-connected deployment strengthens local energy storage and dispatch capabilities, while black-start functionality supports grid restoration during major power disruptions.
The installations form part of Tata Power’s broader strategy to modernise Mumbai’s electricity infrastructure and enhance the resilience of the city’s power network.
In April 2025, the Maharashtra Electricity Regulatory Commission (MERC) approved Tata Power’s proposal to deploy 200 MWh of battery energy storage capacity across 10 strategic locations in Mumbai.
The wider programme is designed to strengthen grid stability, optimise peak-demand management, improve reactive power support and accelerate power restoration for critical infrastructure, including hospitals, metro rail networks, airports and data centres.
