Tata Power gets nod to install 100 MW battery storage in Mumbai; check how shares are performing

“The entire 100 MW system will be installed across 10 strategically located sites, especially near load centres across Mumbai Distribution, centrally monitored and controlled from Tata Power’s Power System Control Centre,” Tata Power said in a statement to the stock exchanges.

During the intraday period, shares of Tata Power were trading at ₹352.80 apiece, tumbling 4.38% on the National Stock Exchange.

Equipped with advanced 'black start' functionality, Tata Power explained that the BESS will enable a swift recovery of power supply to critical infrastructure, including the metro, hospitals, airports, and data centres, 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 optimise reactive power management, improving peak demand efficiency and strengthening the city's power infrastructure,” the company further said.

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 utilising it during high-cost peak hours, thereby ensuring reduced tariffs for consumers in the future.

“Beyond enhancing grid reliability, the BESS will offer ancillary services, including frequency regulation and voltage support, further strengthening grid stability. It will also enable better utilisation of solar energy by storing surplus daytime power and making it available during peak demand, ensuring optimal renewable energy integration with an increase in green energy consumption,” Tata Power explained.

Future plans include the integration of BESS into the Distributed Energy Resource Management System (DERMS) to enhance operational efficiency, the company said.

Tata Power Company Limited, a leading integrated power company and a part of the Tata Group, India's largest multinational business conglomerate, owns a diversified portfolio of 15.6 GW.
