India is set for a massive leap in energy storage, with pumped storage capacity projected to rise 13-fold to 94 GW by 2035-36. Battery storage capacity is also expected to soar to 80 GW from just 0.27 GW currently, according to a new policy document.
This ambitious expansion reflects India’s commitment to building a resilient, renewable-driven power sector. The growth in storage capacity will play a pivotal role in balancing intermittent solar and wind generation, ensuring grid stability, and supporting the country’s clean energy transition.
Pumped Storage Expansion
Pumped storage, a proven technology for large-scale energy balancing, will be scaled up significantly to 94 GW. This will help manage peak demand, reduce reliance on coal, and enhance flexibility in India’s electricity grid.
Battery Storage Growth
Battery storage capacity is projected to surge to 80 GW by 2035-36, marking a transformative shift from current levels. This growth will be driven by falling costs, technological innovation, and rising demand for decentralized energy solutions.
Strategic Importance
Together, pumped and battery storage will form the backbone of India’s renewable energy future, enabling efficient integration of solar and wind power while strengthening energy security and sustainability.
