India's data center industry is shaping up to be one of the country's biggest technology bets of the coming decade, and the reason has less to do with software than with electricity.

According to Deloitte, India's data center capacity could reach 9 to 12 gigawatts by 2031, creating what the firm describes as a $100 billion opportunity. The growth is being driven by rising adoption of artificial intelligence, which is fueling demand for GPU-based infrastructure — the specialized, power-hungry hardware used to train and run AI systems.

Crucially, Deloitte's Vivek Gupta said financing is unlikely to be a constraint on this expansion. In other words, the money to build is expected to be there.

So what could hold things back? According to Business Today, industry experts argue that AI's biggest bottleneck is no longer computing chips from companies like Nvidia, but reliable electricity and the supporting infrastructure around it. Data centers packed with GPUs consume enormous amounts of power and require steady energy, cooling and water to operate.

That reframing carries a pointed message for investors. As the reporting puts it, India's biggest AI investment opportunity may be power, not software — meaning the returns could flow to the companies that generate electricity and build the physical backbone, rather than only to those writing AI applications.

The theme is echoed across coverage from CNBC-TV18, Business Today and MSN, all pointing to the same underlying shift: the AI race is increasingly a race to secure energy and real-world infrastructure.

Why it matters: if the projections hold, the winners of India's AI era may be defined less by clever algorithms and more by who can keep the lights on for the machines that run them.
