Why Chennai Is Becoming India's EV and Electronics Manufacturing Hub
Chennai's Second Act: How the Detroit of Asia Is Becoming India's EV and Electronics Capital. An in-depth look at EV makers, electronics exporters, and infrastructure.
Introduction
In 1998, a small hatchback rolled off a brand-new assembly line in Sriperumbudur, about 40 kilometres from Chennai. It was a Hyundai Santro, and at the time it looked like just another factory opening. It turned out to be the start of something much bigger.
Over the next two decades, carmakers from around the world set up base around Chennai. Suppliers followed them. Training institutes, logistics firms and engineering service companies followed the suppliers. By the 2010s, the city had earned a nickname it still wears proudly: the Detroit of Asia.
Now, the same highways that carried millions of petrol and diesel cars to the ports are carrying something new. Electric vehicles. Smartphones. Battery packs. Circuit boards. The names on the factory gates increasingly come from Shenzhen, Hanoi and Taipei as well as Seoul and Stuttgart.
Chennai isn't losing its identity. It's writing its second act. And for manufacturers deciding where to build next, understanding that story has never mattered more.

Chennai isn't losing its identity. It's writing its second act. And for manufacturers deciding where to build next, understanding that story has never mattered more.
The First Act: How Chennai Built Its Foundation
To understand why Chennai is winning in EVs and electronics today, you have to look at what it built in the past.
When the first global automakers arrived in the late 1990s, they needed more than land. They needed suppliers who could deliver parts on time, engineers who could run complex lines, and ports that could handle exports. Chennai had the beginnings of all three, and over time it built the rest.
Hyundai, Renault-Nissan, Ford, BMW and later Daimler set up operations in and around the city. Two-wheeler makers like Royal Enfield and TVS strengthened the base further. Each new plant attracted dozens of component makers, from seat manufacturers to wiring harness specialists.
The result was something that's very hard to copy: an industrial ecosystem. In an ecosystem, every new company makes the next one's decision easier. A carmaker arriving today doesn't have to persuade suppliers to move. They're already here, often just a few kilometres away.
That foundation is the single biggest reason Chennai is now leading India's shift to new-age manufacturing.

The Second Act Begins: Electric Vehicles
On the surface, an electric car looks very different from a petrol one. There's no engine, no fuel tank and no exhaust. But under the skin, building an EV is still building a vehicle.
It still needs a body shop, a paint shop and an assembly line. It still needs seats, glass, brakes, lights and suspension. It still needs testing, quality control and a workforce that knows how to put thousands of parts together with precision.
Chennai already has all of that. So when EV makers started looking at India, the city was a natural shortlist candidate.

Chennai already has all of that. So when EV makers started looking at India, the city was a natural shortlist candidate.
- BYD:One of the world's largest EV makers, assembles electric cars for the Indian market near Sriperumbudur. It's a striking sign of how far the region has come: a Chinese EV giant choosing the same corridor where India's modern car industry took off.
- VinFast:The Vietnamese carmaker, picked Tamil Nadu for its first Indian plant. The company opened its facility at Thoothukudi in 2025 and has already signed up to expand it, adding electric buses and scooters to its line-up. For a newcomer, choosing a state with proven manufacturing depth reduces risk from day one.
Meanwhile, the established players are going electric on familiar ground. Hyundai's EV journey is unfolding in the same region where its first Santro was built. Royal Enfield, a Chennai original for decades, is exploring an electric future of its own. And across Tamil Nadu, electric two-wheeler makers have built some of the country's largest plants.
The shift creates new needs too. EVs bring battery packs, motors, power electronics and charging equipment, and each of these is creating a fresh wave of suppliers looking for space close to the OEMs they serve.

The Quiet Boom: Electronics Manufacturing
While EVs grab the headlines, an even bigger transformation has been happening quietly in the background.
Tamil Nadu is now India's largest exporter of electronics, accounting for more than 40% of the country's electronics exports. Much of that output comes from a single district, Kancheepuram, which has climbed to become India's second-largest exporting district.
Chances are, the smartphone in your pocket has a connection to this region.
Foxconn runs its largest Indian operation at Sriperumbudur, employing tens of thousands of people. Pegatron built its iPhone plant at Chengalpattu, just south of Chennai, and Tata Electronics has since taken a majority stake in that business, a sign of how seriously Indian companies are now investing in high-end electronics. Samsung, Flex and Dell add further depth across phones, consumer electronics and IT hardware.
The most exciting part of the electronics story is what comes next. For years, India mostly assembled devices from imported parts. Now the focus is shifting to making those parts here: displays, batteries, camera modules, enclosures and circuit boards.
Tamil Nadu has moved fast on this. It has won the lion's share of projects under the Centre's electronics component manufacturing scheme, thanks to state incentives that sit on top of central support. That means more component makers will be setting up near Chennai in the coming years, and every one of them will need factory and warehouse space.

Why Chennai Keeps Winning
Plenty of Indian states offer cheap land and generous incentives. So why do so many global manufacturers keep choosing Chennai? It comes down to five advantages that work together.
The 5 Structural Advantages
- 1Ports on the doorstep:Chennai is served by three major ports: Chennai Port, Kamarajar Port and Kattupalli. All are within easy reach of the main industrial belts. For export-driven companies, that means shorter lead times, lower logistics costs and more options if one route gets congested.
- 2Suppliers who are already here:Decades of automotive and electronics manufacturing have left behind thousands of established suppliers. A new manufacturer can find local partners for everything from precision machining to packaging. That cuts start-up time and reduces dependence on imports.
- 3A deep and diverse workforce:Tamil Nadu has one of India's largest pools of skilled manufacturing workers, backed by a strong network of engineering colleges, polytechnics and ITIs. The state also stands out for women's participation: it employs a larger share of India's women factory workers than any other state. That didn't happen by accident. Large-scale worker housing projects, like the women's residential complex at Vallam Vadagal near Sriperumbudur, make it easier for workers to live safely close to their jobs. For employers, that means a wider talent pool and steadier retention.
- 4Cleaner power:Global brands increasingly want to know where their suppliers' electricity comes from. Tamil Nadu has a head start here, with around 60% of its installed power capacity coming from renewable sources, led by wind and solar. For manufacturers selling to customers with clean-energy targets, that's a real commercial advantage.
- 5A government that competes:Tamil Nadu has built a reputation for moving quickly on large investments, from land allocation to approvals. Its incentives for electronics and EVs sit on top of central schemes, and the state has consistently landed big-ticket projects that other states were also chasing.
None of these advantages is unique on its own. Together, they create a place where manufacturers can set up quickly, operate reliably and grow with confidence.
The Road Ahead: What the Next Decade Could Look Like
If the last 25 years were about building vehicles, the next 10 are likely to be about building the technology inside them, and inside almost everything else.
Expect more battery manufacturing, as EV makers look to source cells and packs locally. Expect more electronic component plants, as India works to reduce its reliance on imported parts. And expect more advanced logistics hubs, because high-value goods need modern, secure and well-connected warehousing.
The state's own ambitions are bold. Tamil Nadu aims to become the electronics hub for the wider Global South, and to move from simple assembly towards research, design and higher-value manufacturing.
For businesses, this creates a clear window of opportunity. The companies that secure the right locations and facilities now will be best placed as the ecosystem deepens.

Why the Building Matters as Much as the Location
There's one part of this story that often gets overlooked: the factory building itself.
EV and electronics makers are far more demanding occupiers than traditional manufacturers. Here's what they typically need:
EV and electronics makers are far more demanding occupiers than traditional manufacturers. Here's what they typically need:
- Speed:Global product launches run on fixed dates, so facilities must be ready on time, every time.
- Power:Automated lines and battery production draw large, steady loads, so reliable high-tension power from day one is essential.
- Clean energy readiness:Roofs need to be engineered to carry solar panels, without expensive retrofits later.
- Strong, flexible spaces:Heavy equipment and high-bay storage need engineered floors and generous clear heights.
- Clean paperwork:Multinational auditors check titles, approvals and building standards, so governance matters.
For these companies, a delayed approval or an underpowered building isn't a small problem. It can hold up an entire product line. That's why choosing the right developer has become as important as choosing the right city.
