Adani Green Plans 15 GWh Annual Battery Storage Deployment From Next Year

Adani Green Energy has announced plans to deploy more than 10 GWh of battery energy storage in the current financial year and approximately 15 GWh or more annually from the following year, sustained for at least five to ten years. The company also intends to invest approximately Rs 25,000 crore annually from next year onwards as India targets 411 GWh of total storage capacity by 2031-32.

The announcement was made by a senior Adani Green executive at the Economist's Resilient Futures Summit. Gautam Adani has committed US$100 billion to India's energy transition, with a flagship 30 GW renewable energy park at Khavda in Gujarat expected to become the world's largest single-location facility. The company is co-locating battery systems with solar and wind assets across Gujarat and Rajasthan and has declared 15,000 MWh of pumped storage in its development pipeline. As of January 2026, India had 13,120 MW of pumped storage under construction and another 9,580 MW approved.

Battery storage is positioned as the solution to transmission congestion, which is currently India's most significant barrier to renewable integration. The Adani executive stated that batteries can store daytime solar power for discharge during evening hours when transmission lines are underutilised, effectively doubling the capacity of existing evacuation infrastructure without the three-to-four-year lead time of new transmission lines. India currently has less than 1 GWh of commissioned battery storage, while 10,658 MW of BESS is under construction and another 22,347 MW is at the tendering stage.

Despite strong pipeline activity, deployment faces structural challenges including high upfront capital costs, China-dependent supply chains for lithium-ion cells (which account for approximately 55 per cent of system costs), transmission constraints and the absence of dedicated long-term financing products. Union Minister Pralhad Joshi confirmed that production-linked incentive schemes are supporting domestic battery cell manufacturing, with at least 44 GW expected through these initiatives. New tenders are increasingly requiring firm and dispatchable renewable energy combining solar, wind and storage so electricity can be supplied on demand.
