South Asia’s largest battery energy storage system (BESS)

The Delhi Power Minister inaugurated at Kilokari a 20-MW battery energy storage system (BESS), said to be the “largest” in South Asia.

• The system is also India’s “first commercially approved” utility-scale energy storage system that will ensure improved power supply in different South Delhi areas, covering a population of over one lakh people.
• The energy storage system is designed to deliver up to four hours of reliable daily power — two hours each during the day and night — directly benefiting over one lakh residents in the densely populated Kilokri area in South Delhi.
• The system extends multiple benefits such as improved power supply, enhanced grid stability, optimised power purchase costs, peak shaving, reduced overloading of network and renewable power integration.
• This initiative significantly enhances grid reliability, especially during peak demand periods, setting a new standard for urban energy management.
• The project, completed within a period of one year, leverages advanced Lithium Iron Phosphate (LFP) technology known for superior safety, thermal stability and durability.
