Delhi marked a major leap in urban energy infrastructure with the inauguration of a 20-MW (40 MWh) Battery Energy Storage System (BESS) at Kilokari, deemed the “largest” utility-scale system in South Asia. The project, inaugurated by Delhi Power Minister Ashish Sood, is hailed as India’s first commercially approved utility-scale energy storage installation.
Installed at the BRPL substation, the BESS is engineered to supply up to four hours of dependable daily power—two hours during the day and two at night—serving over one lakh residents in the densely populated region of south Delhi. Minister Sood called the project a “historic milestone” for both Delhi and India’s energy sector, setting a new benchmark in regulatory and technological progress.
Developed with support from IndiGrid, GEAPP, and TERI, the system is described as South Asia’s largest standalone battery-inverter power setup. The government intends to replicate this model across Delhi to eliminate power outages, particularly during peak demand periods.
The advanced energy storage system brings several benefits, including improved grid reliability, better power purchase efficiency, and seamless integration with renewable energy sources. Additionally, it aims to reduce network overloading and implement effective peak shaving strategies.
The Delhi government has reaffirmed its commitment to investing in such future-forward technologies. The Kilokari BESS initiative is a collaborative effort between BRPL, IndiGrid, GEAPP, and Amperehour, signaling a robust push toward modernized, resilient, and sustainable urban energy solutions.
