Adani Green Energy Limited (AGEL) has commissioned a cumulative 3.37 gigawatt-hour (GWh) Battery Energy Storage System (BESS) at Khavda in Gujarat, India — now recognized as the world's largest single-location battery storage installation outside China. The company says the build is also one of the fastest utility-scale storage deployments globally, completed in just ten months.
Inside the Khavda installation
The newly operational capacity includes an earlier 1.37 GWh system commissioned in March 2026. It sits within AGEL's sprawling Khavda complex, where more than 538 square kilometers of barren land is being transformed into what is expected to become the world's largest renewable energy plant. AGEL plans to develop 30 GW of renewable capacity at the site by 2029; roughly 9.9 GW is already operational. The storage system pairs lithium-ion batteries with advanced energy-management software to firm up intermittent generation and deliver round-the-clock clean power.
Why storage is the missing link
Because solar and wind output swings with weather and season, large batteries are essential to store surplus energy during peak generation and release it during peak demand. AGEL says the 3.37 GWh system can supply electricity to nearly one million homes for a full day, meet the peak demand of cities such as Chandigarh and Indore, cover the entire power needs of the state of Goa, or run more than 12 million LED bulbs continuously for ten hours. The milestone follows global momentum in storage chemistry, including Ganfeng's 500 Wh/kg solid-state battery milestone.
India's grid balancing act
India is adding renewable capacity at record pace, and that growth is straining a grid built for steady thermal output. Utility-scale storage is fast becoming the linchpin that lets operators absorb midday solar surpluses and discharge them into the evening peak, deferring new fossil plants and reducing curtailment. By concentrating 3.37 GWh at a single site alongside gigawatts of co-located solar and wind, Khavda offers a template for pairing generation and storage at industrial scale — a model regulators across South Asia are watching closely.
A 50 GWh ambition
Sagar Adani, Executive Director of AGEL, said large-scale storage infrastructure will be critical to building a flexible, resilient clean-energy network as India accelerates its renewable transition. The company is targeting more than 10 GWh of additional battery storage in FY2027 and aims to scale to 50 GWh over the next five years. The deployment reinforces a broader shift toward firmed renewables, echoing projects such as China's undersea wind-powered AI data center and the moment when solar and wind outproduced gas globally.
