Adani Green Energy Ltd (AGEL) said on 1 October that its operational battery energy storage capacity at Khavda in Gujarat has reached 6.63 gigawatt-hours (GWh). The figure was 3.55 GWh in June 2026. Storage of this kind lets solar and wind power be held back and supplied when the grid needs it, which matters as India adds more renewable capacity.
According to the company, it now holds more than 50 per cent of India’s operational battery storage capacity of about 12.6 GWh. These market-share and capacity figures come from AGEL’s own statement.
What the numbers mean
A gigawatt-hour is a measure of stored energy. AGEL says 6.63 GWh can power around two million homes for a day or support peak demand in cities such as Nagpur, Patna or Vizag for several hours. The company also says it equals the battery capacity of more than 150,000 mid-sized EVs. It says this is almost twice the Delhi Metro’s estimated daily electricity requirement.
On speed, AGEL says it reached 6.63 GWh within 14 months of starting on-site construction, and commissioned the latest addition in 10 months. A stock-exchange summary of the commissioning reports that 3,081 MWh of storage was added alongside 481.9 MW of solar and wind capacity. The company’s total operational renewable capacity is now 20,762.70 MW.
The company describes Khavda as the world’s largest operational battery installation at a single location. In May, it described its then 3.37 GWh as the world’s largest single-location battery storage deployment outside China. These are company claims, and I could not independently verify the global ranking.
How the system works
The batteries use lithium-ion technology. They are integrated with an energy management system and automated telemetry that manage charging and discharging and support grid services. They sit within a wider project: AGEL is building a 30 GW renewable energy plant at Khavda across 538 square kilometres of barren land. According to the company, storage can help with grid stability, peak demand and reducing curtailment, which is when available clean power goes unused.
Executive Director Sagar Adani called the milestone “a significant milestone for AGEL and India’s clean energy transition.”
What this means for India
Solar and wind output rises and falls with the weather, while demand peaks in the evening. Storage at this scale shows how that gap can be narrowed. By the company’s account, one developer now holds over half of the country’s operating battery capacity, so national progress depends heavily on a few large projects. AGEL says it is on track to add over 10 GWh in FY 2026-27 and is targeting 50 GWh over five years. Whether that is delivered will show how quickly India can make renewable power dependable.
What happens next
AGEL said it is on track to add over 10 GWh of BESS capacity in FY 2026-27 and is targeting 50 GWh of storage capacity over the next five years. Mr Adani also said the company will keep scaling both battery and pumped storage to support a lower-carbon grid.
