Adani Green Energy commissions largest battery storage facility outside China

Adani Green Energy Ltd (AGEL) officially announced here on Tuesday that it has commissioned a cumulative 3.37 Gigawatt-hour (GWh) Battery Energy Storage System (BESS), which is the world’s largest single-location battery storage deployment outside China.

According to an official company statement, the latest deployment includes the 1.37 GWh capacity commissioned in March 2026, taking AGEL’s total operational BESS capacity at Khavda in Gujarat to 3.37 GWh. The project was executed within just 10 months of the commencement of on-site construction, marking one of the fastest utility-scale battery storage deployments globally, as per the statement.

Adani Green Energy Ltd (AGEL) is India’s largest and one of the leading renewable energy companies in the world, enabling the clean energy transition. AGEL develops, owns, and operates utility-scale grid-connected solar, wind, hybrid and energy storage solutions. AGEL currently has an operating renewable portfolio of 19.7 GW, the largest in India, spread across 12 states, the statement mentioned.

The company has set a target of achieving 50 GW by 2030, aligned to India’s decarbonisation goals. AGEL is focused on leveraging technology to reduce the Levelised Cost of Energy (LCOE) in pursuit of enabling large-scale adoption of affordable clean energy. AGEL is developing the world’s largest renewable energy plant (30 GW) on barren land at Khavda, Gujarat, covering 538 square kilometres, an area five times larger than Paris, according to the statement.

The commissioning marks a major milestone in strengthening grid reliability, peak-hour supply and enabling renewable energy to deliver dependable, round-the-clock power at scale.

AGEL mentioned in its statement that it plans to add more than 10 GWh of battery storage capacity in FY27 and scale this to 50 GWh over the next five years.

AGEL’s 3.37 GWh BESS can store enough clean energy to power nearly one million homes for an entire day, supporting peak electricity demand in cities like Indore, Chandigarh or the entire state of Goa. It can also power more than 12 million LED bulbs continuously for ten hours. This would be a game changer as battery storage will help keep renewable-heavy grids stable and deliver green power round-the-clock, according to the statement.

Commenting on the development, AGEL’s Executive Director Sagar Adani said, “Large-scale energy storage will play a defining role in the next phase of India’s clean energy transition. As renewable energy capacity scales rapidly, storage infrastructure becomes critical for delivering reliable, round-the-clock clean power. With the commissioning of the 3.37 GWh BESS at Khavda, AGEL is strengthening the foundation for resilient, dispatchable and flexible energy systems. Our investments in battery storage reflect a long-term commitment to building future-ready clean energy infrastructure at a global scale”.

The BESS project integrates advanced energy management systems with lithium-ion battery technologies to optimise efficiency, reliability and grid responsiveness. AGEL’s BESS project has been strategically located at Khavda in Gujarat to further strengthen the world’s largest renewable energy plant, where AGEL is developing 30 GW by 2029, of which 9.9 GW is already operational, according to the statement.

As renewable energy adoption accelerates globally, utility-scale battery storage is emerging as critical infrastructure for reliable clean energy delivery. Renewable energy output varies with time, climate, season or geographic location. BESS helps address this variability since it stores extra energy and supplies it during peak demand, the statement mentioned.
