INDIA’S ENERGY STORAGE LANDSCAPE Q1 2026 REPORT – INDIA'S CUMULATIVE INSTALLED BATTERY ENERGY STORAGE CAPACITY REACHES 5.9 GWh
India’s cumulative installed battery energy storage capacity reached 5.9 GWh as of March 2026.
Standalone energy storage accounted for 73% of India’s cumulative capacity, followed by 15% from solar-plus-wind with storage (RTC capabilities) projects and 11% from solar-plus-energy storage projects. The remaining share was split among emerging configurations, including solar-plus-wind with storage and floating solar with storage, each contributing less than 1%.
The pumped storage project (PSP) pipeline remained strong, with 57.2 GW of projects in various stages of development. Out of 7.2 GW installed, 5.7 GW of PSPs were operational as of March 2026.
The energy storage sector is now becoming an integral component of India’s power system, driven by rapid growth in renewable capacity, increasing solar penetration, and evolving regulatory frameworks.
In Q1 2026, India’s energy storage development pipeline reached 69 GWh, comprising 41 GWh of standalone storage, 11 GWh of solar-plus-wind with storage, 9 GWh of solar-plus-energy storage, and 1 GWh of solar-plus-wind with storage projects (RTC capabilities). Additionally, there were 6 GWh of renewable energy-plus-storage projects, with unspecified configurations for both renewable and storage.
Gujarat had the largest pipeline of standalone battery storage capacity at 10 GWh.
Multiple agencies issued tenders totaling 18 GW during Q1 2026 and auctioned more than 4 GW of standalone storage projects. Tender activity rose 47% from 12 GW in Q4 2025, while auction volumes declined 61% from 11.1 GW in Q4 2025.
