Hidden Winners of India’s $25 Billion Data Centre Revolution

Why Everyone’s Quietly Betting on Data Centres

While most retail investors are chasing the next electric vehicle stock or riding the AI hype train, the real money might just be quietly humming away in cold, sterile buildings filled with blinking servers—India’s data centres.

The numbers don’t lie. India’s data centre market is expected to attract a jaw-dropping $25 billion in investment over the next 5–6 years. What’s fueling this? Everything digital—from streaming reels to scanning QR codes—needs storage, speed, and security. And with the Indian government pushing for data localisation, the demand is only getting hotter.

But here’s the twist: it’s not the big-name tech giants or real estate players that could see the fastest gains.

It’s the smallcap companies.

From cabling to cooling, from cybersecurity to backup power, these niche smallcap stocks are quietly positioning themselves at the heart of India’s data centre revolution. They don’t just support the infrastructure—they are the infrastructure.

In this blog, we’ll break down the biggest trends in this digital gold rush and reveal five lesser-known data centre stocks in India that could offer multibagger potential in the long run.

The Real Boom: India’s Data Centre Gold Rush

The digital economy isn’t just growing—it’s exploding. And India, with its 1.4 billion people, is sitting right at the epicenter of this data explosion.

From UPI payments to OTT binge sessions, from government databases to AI models—everything is now data-driven. And all that data needs a home.

That’s where data centres come in.

So… why the sudden boom?

A few key reasons:

• Digital India push: The government’s aggressive push for digitisation and data localisation laws means more data must be stored within the country.
• AI + 5G = data tsunami: The rise of GenAI, IoT devices, and 5G technology is generating massive volumes of data that need to be processed and stored closer to the user—leading to edge and hyperscale data centre demand.
• MNC interest: Big global players like Amazon Web Services, Google, Microsoft, and Meta are already investing heavily to build or lease data centres in India.

The numbers speak louder

• India currently has ~870 MW of operational data centre capacity.
• That number is expected to triple to over 2,500 MW by 2030.
• Nearly ₹2 lakh crore ($25 billion) is expected to flow into this sector in the next 5–6 years.

But here’s what most people miss:

This boom isn’t just about tech giants building shiny new server farms. It’s about the massive ecosystem being built around it.

That’s where smallcap companies come in—powering, protecting, and connecting India’s data future. And for smart investors looking at data centre stocks India, that’s where the real opportunity lies.

The Backbone: 5 Sectors That Power Every Data Centre

Let’s get one thing straight: a data centre isn’t just a building with servers.

It’s a complex, high-security, ultra-efficient machine that needs power, cooling, networking, and infrastructure running 24/7—without a hiccup.

And while the spotlight is on the Googles and Amazons of the world, the real heroes are often smaller players working behind the scenes.

Here are 5 key sectors that make data centres tick—and the smallcap companies in each space that could ride this ₹2 lakh crore wave:

1. Electrical Infrastructure

You can’t run petabytes of data without massive amounts of power. Data centres need transformers, substations, cabling, and backup systems—all tailored for round-the-clock operation.

🧠 Opportunity: Smallcap electrical EPC players with government and private project experience.

2. Power Backup & Cooling

Servers generate heat. A lot of it. Uninterrupted power (with DG sets or batteries) and precision cooling systems (HVACs, chillers, etc.) are critical for keeping operations stable.

🧠 Opportunity: Niche companies in industrial cooling and backup generation are set to thrive.

3. Network Infrastructure

Data without connectivity is like gold buried underground. Fibre optic cabling, network switches, and edge computing nodes are vital for the fast and secure transmission of data.

🧠 Opportunity: Telecom infra players and fibre-optic specialists stand to benefit.

4. Data Centre Construction

Not your average building—these are fortified, fireproof, seismic-resistant bunkers with raised floors, smart racks, and energy-efficient designs.

🧠 Opportunity: Specialised construction firms with tech-building experience will grow with hyperscale data centre expansion.

5. Real Estate & Leasing

Not every company wants to build their own facility. That’s why data centre parks—where companies lease space—are in high demand, especially around Mumbai, Chennai, and Hyderabad.

🧠 Opportunity: Real estate developers with exposure to industrial leasing or tech parks can gain massively.

These are the sectors quietly fuelling the rise of data centre stocks India—and helping create a new investing frontier outside of IT bluechips.

Now let’s get to the juicy part—which smallcap companies are actually benefiting from all this?

5 Smallcap Companies Riding the Data Wave

Alright, theory’s great—but let’s talk stocks.
Here are five smallcap companies that are uniquely positioned to ride the data centre boom in India. Each one solves a crucial piece of the puzzle—and they’ve got the financials and tailwinds to back it up.

1. Bajel Projects – Powering the Grid

What they do: Power transmission EPC player, formerly part of Bajaj Electricals. They handle turnkey projects for substations and transmission lines.

Why they matter: As data centres demand uninterrupted high-voltage power, companies like Bajel become indispensable for laying down and maintaining that power backbone.

Growth trigger: The parent company’s backing, recent demerger, and government push for power infra make this a quiet winner.
