India Stationary Energy Storage Market Overview Report 2020-2027

India Energy Storage Alliance (IESA) has estimated the stationary energy storage market potential in India to be around 230 GWh during the period 2020-2027. The share of grid scale applications contribution is expected to be 15%, with behind-the-meter applications making up the rest. In grid application, renewable energy integration takes up majority of this share, split between solar and wind projects. CEA also projects requirement of 136 GWh of storage in the grid at various levels by 2030.

Focusing on renewables, the penetration of storage in wind will be more gradual than the penetration rate in solar, as has been observed in RE + storage projects across the globe. The duration of storage in each such project, where we also combine hybrid projects which will come with storage, is anticipated to be of 1-hour duration initially and gradually increasing up to 2-3 hours in the long term or after 2025. The requirement with wind in terms of hours is less due to wind being available throughout the day. Thus a long duration storage requirement with wind is less.

We expect the penetration of storage in terms of MWh in each wind + storage or hybrid project to grow, with storage being 10% of capacity initially and gradually increasing to around 30% by 2027.

IESA has been continuously tracking the developments in the stationary energy storage market in India and has released six editions of its annual stationary energy storage market overview reports. Covering grid scale and behind-the-meter applications, the reports track 13 sub-segments, with a deep dive into each of these segments. This covers key drivers and restraints, market share analysis, technology split, relevant case studies and year-wise market potential for a period of seven years.
