Reliance Industries Ltd turns to China’s major battery maker Contemporary Amperex Technology Co. Ltd (CATL) to source components for battery energy storage systems amid the company’s large-scale expansion goals in the renewable energy sector, according to a report by Bloomberg. 

Upon the deal, this will become a major source of battery components for Reliance after its deal with China’s Xiamen Hithium Energy Storage Technology Co. collapsed over Beijing’s tightening restrictions on overseas transfers of strategic green energy technologies. 

World’s largest renewable energy manufacturing hub 

Reliance is constructing a mega battery gigafactory in Jamnagar. Once completed, it is expected to become one of the world’s largest renewable energy manufacturing hubs, with an investment of more than ₹75,000 crore. 

The battery gigafactory is scheduled to begin production by the second half of 2026. It features an initial modular footprint of 30 to 40 GWh annual capacity, with blueprint designs to scale up to 100 GWh annually. 

The Jamnagar energy storage complex is aligned with RIL Chairman Mukesh Ambani’s ambitions to lead India’s clean energy transition as the country aims to achieve 500 GW of renewable power capacity by 2030. 

India’s energy storage market is booming 

BloombergNEF said in a May 6 note that India’s energy storage market is expected to surge to 336.7 GWh by 2035, nearly 115 times the cumulative installations recorded in 2025. The sharp growth outlook highlights why global battery makers, especially Chinese companies such as CATL, are aggressively seeking a larger presence in India’s fast-growing storage market. 

India’s push towards renewable energy and round-the-clock power supply has significantly increased the demand for large-scale battery storage systems, which are considered critical for balancing intermittent solar and wind power generation. 

Industry experts believe energy storage will play a key role in improving grid stability and reducing dependence on fossil fuel-based power during peak demand hours. 

Reliance has been rapidly expanding its presence across the clean energy value chain, including solar modules, green hydrogen, fuel cells, and battery manufacturing. The company had earlier announced plans to build an integrated renewable energy ecosystem in Jamnagar as part of its long-term strategy to become a major player in the global clean energy sector. 

According to analysts, partnerships with global battery technology companies could help Reliance accelerate localisation and strengthen India’s domestic energy storage manufacturing capabilities.
