Tata Power has secured approval from the Maharashtra Electricity Regulatory Commission (MERC) to set up a 100 MW Battery Energy Storage System (BESS) in Mumbai over the next two years. This state-of-the-art BESS, featuring advanced “black start” capabilities, will ensure rapid restoration of power to critical infrastructure, such as the metro, hospitals, airports, and data centers, in the event of grid disruptions.
By doing so, it will help prevent widespread outages and boost the city’s power grid resilience. The system’s advanced technology will also enhance reactive power management, optimizing peak demand performance and strengthening Mumbai’s electrical network. With its high ramp-rate ability, the BESS will assist in managing peak loads, ensuring a stable power supply even during periods of high demand.
It will also reduce electricity purchase costs by storing energy during off-peak times and releasing it during peak hours, ultimately lowering consumer tariffs. Additionally, the system will allow for deferral of costly infrastructure upgrades by efficiently managing load fluctuations and using stored energy.
Beyond improving grid reliability, the BESS will provide essential services such as frequency regulation and voltage support, contributing to greater grid stability. It will also enable more effective use of solar energy by storing excess power during the day for use during peak demand periods, facilitating better integration of renewable energy and increasing green energy usage. Furthermore, the installation will help Tata Power meet energy storage obligations.
The entire 100 MW system will be deployed across 10 strategically chosen sites, primarily near key load centers in Mumbai. It will be centrally monitored and controlled from Tata Power’s Power System Control Center (PSCC).
Tata Power, a key player in India’s energy sector and part of the Tata Group, operates a diverse 15.6 GW portfolio across the power generation, transmission, distribution, and solar manufacturing sectors. As a leader in the country’s clean energy transformation, Tata Power generates 6.7 GW of clean energy, accounting for 43% of its total capacity. The company is committed to achieving carbon neutrality by 2045 and has formed numerous partnerships across the public and private sectors to advance India’s energy goals, serving approximately 12.5 million customers nationwide.
