India’s renewable energy transition is accelerating, backed by ambitious targets and government support. The country is aiming for 500 GW of renewable energy capacity by 2030, with a specific focus on 74 GW of Battery Energy Storage Systems (BESS) by 2031–32. To drive adoption, the government has committed ₹54 billion in viability gap funding, which is expected to attract around ₹330 billion in total investments.
Battery Energy Storage Systems (BESS) are becoming a cornerstone of India’s energy strategy, enabling better grid stability, peak load management, and renewable energy integration.
