Adani Group has announced its entry into the Battery Energy Storage Systems (BESS) sector with a landmark 1,126 MW / 3,530 MWh project — India’s largest and among the world’s biggest single-location energy storage installations.
The project, comprising over 700 BESS containers, will be commissioned by March 2026’ This and will extend the power capacity of 1,126 MW by approximately three hours, marking a major step forward in India’s clean energy transition.
Located at Khavda, home to the world’s largest renewable energy plant, the project is in advanced stages of deployment and will utilize cutting-edge lithium-ion battery technology integrated with advanced energy management systems to ensure high reliability and performance. The BESS will play a key role in managing peak loads, reducing grid congestion, and minimizing renewable energy curtailment, strengthening India’s power infrastructure and grid stability.
Gautam Adani, Chairman of Adani Group, said, “Energy storage is the cornerstone of a renewable-powered future. With this historic project, we are not only setting global benchmarks but also reinforcing our commitment to India’s energy independence and sustainability. This initiative will enable us to deliver reliable, clean, and affordable energy solutions at scale.”
This milestone initiative underscores Adani Group’s commitment to accelerating India’s low-carbon transition. By enabling round-the-clock renewable power and supporting large-scale integration of clean energy, the project positions Khavda as the world’s largest renewable and storage hub — a cornerstone of global efforts toward sustainable, reliable, and resilient energy systems.
Tata Power plans to set up India’s largest solar wafers, ingots making plant
Tata Power plans to set up the country’s largest solar wafers and ingots manufacturing plant with a capacity of 10GW, chief executive Praveer Sinha said.
The facility to make the ingots and wafers – foundational material for solar cells – would complete Tata Power’s presence across the manufacturing chain for the product. The company already has 4.9 GW of integrated cell and module-making capacity.
Some Indian companies have shifted focus to producing cells as well as ingots and wafers, as higher U.S. tariffs on Indian products have made solar module exports less attractive.
“We find that there’s already adequate capacity of modules and many cell plants are under construction in India,” Sinha said on a post-earnings call, justifying his firm’s plan to set up a wafers and ingots factory.
Adani Group has set up a plant to produce 2GW of ingots and wafers annually so far.
Tata Power’s plans align with the Indian federal government’s push for increased use of locally made ingots and wafers for solar panel manufacturing to cut reliance on imports from China towards the end of the decade.
The government also plans to provide output-linked financial support for wafers and ingots manufacturing.
Tata Power is exploring the use of federal and state financial support for the new factory, Sinha said, adding that a final call on the total investment would be made in the next two months.
Separately, Tata Power is also looking to enter nuclear power generation as India aims to set up at least 100 GW of projects by 2047, up from just over current 8 GW.
