India’s power sector is undergoing a rapid transformation, with renewable energy (RE) capacity projected to exceed 450 GW by 2030. While this growth supports the country’s net-zero target by 2070, it also introduces significant grid challenges—rising curtailment, peak demand mismatches, and frequency instability. Battery Energy Storage Systems (BESS) have emerged globally as a flexible, modular, and rapidly deployable solution to address these concerns, yet their techno-economic viability in India remains under debate.
This paper provides overview of fundamentals of BESS & comprehensive techno-economic and policy analysis of BESS deployment in India, benchmarked against global leaders such as the United States, Australia, and China.
