Energy Storage for India's Energy Transition
India is navigating a pivotal energy transition as it works toward achieving 500 GW of renewable energy capacity by 2030. The report sets the context for energy storage by highlighting the challenges of intermittency and grid stability arising from large-scale solar and wind integration. Energy Storage Systems (ESS)—including Battery Energy Storage Systems (BESS), Pumped Hydro Storage (PHS), and Thermal Energy Storage (TES)—are positioned as critical enablers of a reliable and sustainable power system. They enable firm, dispatchable renewable energy, optimize grid infrastructure, and support round-the-clock electricity supply.
The report compares storage technologies based on technical features, maturity, and applications. BESS is identified as a fast-growing segment driven by falling costs, innovation, and supportive policies such as Energy Storage Obligations, Viability Gap Funding, and PLI schemes. Utility-scale BESS leads deployment, with strong linkages to the EV ecosystem. PHS remains a mature long-duration solution, while TES is gaining importance in industrial and commercial use.
Policy frameworks, global supply chains, financing models, sustainability measures, and sectoral demand are examined. The report concludes with strategic recommendations to accelerate adoption, address gaps, and strengthen India’s clean energy leadership.
