November 12, 2025 : The Adani Group, one of India’s largest conglomerates, has announced ambitious plans to establish the country’s largest grid-scale battery energy storage system (BESS) in Rajasthan. The project marks a major step toward India’s clean energy transition and the government’s mission to ensure 24×7 reliable power through renewable sources.
According to company officials, the project will have an initial capacity of over 1,200 MWh, scalable to 5,000 MWh in the future, making it the single largest energy storage installation in India once completed. The facility will be strategically located near renewable power hubs in Rajasthan, allowing efficient storage of solar and wind power for use during non-generating hours.
Empowering the Clean Energy Transition
Adani Group’s battery storage project aligns with India’s target of achieving 500 GW of non-fossil energy capacity by 2030. As the nation accelerates its renewable energy expansion, grid-scale storage solutions have become essential to balance fluctuations from solar and wind generation.
“Energy storage is the next frontier in India’s renewable journey,” said an Adani spokesperson. “Our investment in large-scale BESS infrastructure will strengthen grid reliability, reduce dependence on fossil fuels, and help achieve national decarbonization goals.”
The system will use advanced lithium-ion and sodium-ion battery technologies, chosen for their efficiency, lifecycle performance, and sustainability. The group is also exploring indigenous manufacturing of battery cells through its subsidiary, Adani New Industries Ltd (ANIL), to reduce import dependence and promote self-reliance under the “Make in India” initiative.
Strategic Importance and Scale
Battery energy storage is increasingly being viewed as the missing link in India’s renewable energy architecture. Unlike conventional power plants, renewables depend on natural conditions—solar during the day, wind at specific times. This intermittency can lead to supply-demand imbalances, voltage fluctuations, and grid instability.
The upcoming Adani project will enable utilities to store excess renewable energy during off-peak hours and release it when demand surges, providing a reliable and cleaner alternative to traditional peaking power plants. The facility is expected to serve both state utilities and private distributors, offering flexible energy dispatch and reducing the need for coal-based generation.
Experts estimate that a 1,000 MWh battery system can supply power to over 1.5 million homes for one hour. With Adani’s planned capacity, the system could significantly improve electricity access and stability in northern and western India.
Economic and Environmental Impact
The project, estimated to cost over ₹12,000 crore, will generate thousands of direct and indirect jobs during construction and operation. It will also contribute to local infrastructure development and promote Rajasthan as a hub for renewable innovation.
Adani Green Energy Ltd (AGEL), the renewable arm of the group, already operates over 10 GW of solar and wind projects across India. This BESS addition will further integrate Adani’s clean energy portfolio and enhance its position as a global leader in sustainable energy solutions.
From an environmental standpoint, the battery system will cut carbon emissions by an estimated 4 million tonnes annually by offsetting coal-based generation. It will also minimize renewable curtailment—when excess energy is wasted due to lack of storage—improving overall utilization of solar and wind plants.
Government and Industry Response
The Ministry of Power and the Central Electricity Authority (CEA) have praised Adani’s initiative as a model for private-sector participation in India’s emerging energy storage market. The government recently introduced viability gap funding (VGF) for storage projects and is working on a National Energy Storage Policy to encourage large-scale adoption.
Analysts suggest that Adani’s early investment in grid-scale storage could give it a strategic edge over competitors like Tata Power, Reliance New Energy, and JSW Energy, all of whom are pursuing similar ventures.
“India will need at least 40 GW/120 GWh of battery storage by 2030,” said energy expert Arun Mehta. “Adani’s initiative positions it at the forefront of this rapidly expanding sector.”
Future Roadmap
The Adani Group plans to operationalize the first phase of the Rajasthan BESS by 2027, followed by gradual scaling based on grid demand and regulatory developments. The company is also exploring opportunities for battery recycling and second-life applications, further strengthening its circular economy model.
Moreover, Adani is in talks with international technology providers from Japan, South Korea, and the US for potential partnerships in battery chemistry, thermal management, and safety systems.
This development underscores India’s commitment to building a sustainable, resilient, and self-reliant energy future—and Adani Group’s pivotal role in shaping that transformation.
Summary
Adani Group will build India’s largest battery energy storage system in Rajasthan, advancing renewable integration, boosting grid reliability, and supporting India’s 2030 clean energy goals with cutting-edge storage technology.
