India’s Data Centre Boom: Can India Become a Global Digital Infrastructure Hub?

Everyone is talking about AI.

But behind every AI model is something far less glamorous  data centres, power, cooling and connectivity.

And India is quietly building all four.

India’s operational data centre capacity reached around 1.75–1.8 GW by H1 2026, according to CBRE and Cushman & Wakefield. More importantly, Cushman & Wakefield estimates another 3.86 GW of capacity is in the pipeline through 2030.

JLL estimates capacity could rise from around 1.6 GW in mid-2026 to 6 GW by 2029, requiring around $110 billion of investment across the broader ecosystem.

So, what is driving this?

1. AI is changing the economics of data centres

Traditional cloud workloads required large computing infrastructure.

AI workloads require something different — high-density computing, specialised chips, significantly higher power requirements and advanced cooling.

Deloitte estimates India could need an additional 40–45 TWh of electricity and 45–50 million sq. ft. of real estate by 2030 just to support the AI-driven data centre expansion.

2. The opportunity extends far beyond data-centre operators

A data centre is not simply a building filled with servers.

It requires:

Power generation → Transmission → Transformers → Switchgear → Cables → Cooling → Construction → Servers → Connectivity

This creates a potentially much larger second-order opportunity for India’s power, electrical equipment, EPC, cooling and construction ecosystem.

The Government estimates data centres could require around 17 GW of power demand by FY2031-32.

3. India has another advantage: digital demand

India has one of the world’s largest digital consumer bases, while enterprises are rapidly adopting cloud and AI.

At the same time, data localisation and digital infrastructure requirements are increasing the need for computing capacity within the country.

ICRA expects India’s third-party data-centre capacity to reach 2.4–2.5 GW by FY2028, involving around ₹90,000 crore of investment during FY2026–FY2028.

4. Mumbai may lead — but the story is spreading

Mumbai remains India’s largest data-centre market, with around 890 MW of operational capacity and another 1,726 MW in the pipeline, according to Cushman & Wakefield.

But Chennai, Hyderabad, Delhi NCR, Pune and Bengaluru are also expanding rapidly.

This geographical diversification matters because power availability, land, fibre connectivity and renewable energy access are increasingly determining where the next data centres are built.

But there is a catch.

Data centres are extremely power-intensive.

S&P Global estimates India’s data-centre electricity consumption could rise from around 13 TWh in 2024 to 57 TWh by 2030.

That means India’s data-centre ambitions cannot be separated from its power and renewable-energy ambitions.

The real question is therefore not:

“How many data centres can India build?”

It is:

“Can India build enough reliable, affordable and sustainable power infrastructure to support them?”

If India gets that equation right, the data-centre boom could become much more than a technology story.

It could become a multi-sector capex cycle — spanning real estate, power, electrical equipment, cooling, construction and digital infrastructure.

And that is where the more interesting investment story may actually lie.
