At 3-gw capacity, Reliance’s data centre in Jamnagar set to be the world’s biggest

Mukesh Ambani’s Reliance Group is set to build what might be the world’s biggest data centre by capacity in Jamnagar, Gujarat. This move comes after a flurry of global investments to capitalise on increasing demand for artificial intelligence (AI) services.
The company plans to equip the data centre with Nvidia Corp’s cutting-edge AI semiconductors, targeting a capacity of 3 gw. Once operational, this facility will surpass the largest existing data centres, which currently have capacities under 1 gw.
Reliance Industries and Nvidia are collaborating with a vision to create AI supercomputers and large language models (LLMs) customised for India’s varied languages.
This groundbreaking initiative aligns Reliance with global tech giants such as Amazon, Microsoft and Alphabet, which are heavily investing in AI-enabled data centres. Recently, US President Donald Trump announced the Stargate Project, involving a total investment of about $500 billion in US-based AI infrastructure in collaboration with Oracle, OpenAI and SoftBank. However, Mr Ambani’s venture stands out due to its unprecedented scale.
The new data centre will integrate renewable energy sources to the greatest extent possible, leveraging Reliance’s green energy complex in Jamnagar. The facility will incorporate solar, green hydrogen and wind projects. However, experts caution that maintaining a consistent power supply will require supplementary resources such as large-scale battery systems and fossil fuels.
