India’s energy storage ecosystem witnessed remarkable expansion in the first quarter of 2026, highlighting the growing importance of battery storage in supporting the country’s clean energy ambitions. According to Mercom India Research’s India’s Energy Storage Landscape Report, the country added 4.6 GWh of battery energy storage capacity during January-March 2026, marking a 941% increase compared with the 442.7 megawatt-hours (MWh) added in the October-December 2025 period. This rapid growth pushed India’s cumulative installed battery energy storage capacity to 5.9 GWh as of March 2026. The surge reflects increasing deployment of storage solutions to improve grid stability, integrate renewable power and ensure reliable electricity supply as India continues to expand its renewable energy base. Rajasthan emerged as the leading state in cumulative installed battery energy storage capacity during the period.
The report also indicates a strong outlook for the sector, supported by a robust project pipeline and rising policy focus on energy storage infrastructure. India had 7.2 GW of installed pumped storage projects as of March 2026, while multiple agencies issued energy storage tenders totalling 18 GW during the quarter. Gujarat accounted for the largest pipeline of standalone battery storage capacity, underscoring the growing geographical spread of storage investments. The rapid scaling of battery and pumped storage projects is expected to play a critical role in balancing variable renewable energy generation and supporting India’s broader objective of building a resilient, low-carbon power system.
