India's Energy Storage Requirement to Reach 888 GWh by 2035-36: Report

India's energy storage capacity is projected to increase from 1 GWh to 888 GWh by 2035-36. This growth aligns with the country's renewable energy expansion and grid reliability enhancement, as detailed in a report by the India Energy Storage Alliance (IESA) and Customized Energy Solutions (CES) released on July 8, 2026, as per The Business Standard news report. 

Current and Projected Energy Storage Capacity 

The report, titled 'India BESS Market Review,' was unveiled at the India Energy Storage Week (IESW) 2026. It highlights the critical role of energy storage in supporting India's renewable energy goals.  

The country's installed battery energy storage system (BESS) capacity saw an 11-fold increase from 0.78 GWh in December 2025 to 8.7 GWh in the first half of 2026, with expectations to exceed 10 GWh by year-end. 

Industry Insights and Developments 

The IESW 2026 event, held at Yashobhoomi (IICC), gathered over 200 exhibitors and more than 10,000 industry leaders from 15 countries. Debmalya Sen, President of IESA, emphasised the significance of energy storage in India's clean energy journey.
