Digital infrastructure, on verified ground

Chennai is India's second data-centre hub, on track from around 202 MW toward 551 MW by 2030. We help operators and developers secure power-adjacent, connectivity-rich, flood-safe land with clean multi-decade title.

• 2nd: largest DC hub in India
• ~202 MW: installed capacity, 2025
• ~551 MW: projected by 2030
• Zone III: lower-risk seismic zone

What the mandate turns on

• Power and connectivity first: Grid capacity, substation adjacency and proximity to subsea and terrestrial fibre decide a site, and are rarely retrofittable, so they are scored before anything else.
• Flood, elevation and CRZ: Chennai's monsoon and coastline make elevation, drainage and Coastal Regulation Zone status decisive in weighing inland against coastal-landing sites.
• Title over decades: A campus is a multi-decade commitment, so title is verified over a long horizon and any multi-parcel assembly is checked parcel by parcel.
• Policy and scalability: Eligibility under the Tamil Nadu Data Centre Policy and room to scale beyond the first phase are mapped, so the site supports the full roadmap.

Subsea connectivity, surplus power, clear policy and low cost put Chennai second only to Mumbai. Indicative third-party context, for orientation, not a quote.

Figures are indicative third-party estimates and vary by source and period. Chennai's capacity is led by Ambattur and Siruseri, with Madhavaram's TN Tech City and the industrial belts offering larger inland parcels. The city pairs multiple subsea cable landing stations with stable power and a defined Tamil Nadu Data Centre Policy, sitting in the lower-risk Seismic Zone III.

The connectivity and grid story is the headline. Whether the parcel is clean over decades, flood-safe and CRZ-compliant is what protects a hyperscale investment. LandLens checks the land beneath the campus.

Infrastructure

• Subsea cable landing stations (Operational): Multiple international submarine cables land at Chennai, with new systems adding capacity, the connectivity backbone that makes the city India's second DC hub.
• TIDCO / state data-centre parks (Approved): Dedicated data-centre zones with power and fibre readiness under the Tamil Nadu Data Centre Policy add purpose-serviced land at Ambattur and the OMR belt.
• Dual-feed grid & renewable corridors (Under construction): Substation and transmission upgrades, plus renewable-energy tie-ins, support the high, redundant power loads hyperscale campuses require.
• Metro & ring-road access to clusters (Under construction): Improved access to Ambattur, Siruseri and Madhavaram eases construction logistics and operations staffing for campuses.

Our process

1. Criteria & shortlist: Power, fibre, elevation, water and scale weighted into a scored candidate shortlist.
2. Risk read: Flood, CRZ, grid-tie and water risks assessed; coastal versus inland weighed.
3. Title & assembly: Multi-decade title verified; any multi-parcel assembly checked and negotiated.
4. Policy & close: Zoning, Data Centre Policy benefits and approvals mapped; acquisition closed.

Frequently asked questions

Why is Chennai India's second data-centre hub?

Chennai pairs multiple subsea cable landing stations with stable, surplus power, a defined Tamil Nadu Data Centre Policy and competitive land and construction costs, in the lower-risk Seismic Zone III. The market is on track from around 202 MW in 2025 toward 551 MW by 2030.

Where do data centres cluster in Chennai?

Ambattur and Siruseri lead current capacity, Ambattur for inland-elevation hyperscale and Siruseri on the OMR corridor for low-latency builds, while Madhavaram's TN Tech City and the industrial belts offer larger inland parcels.

What land criteria matter most for a data centre?

Grid capacity and substation adjacency, proximity to subsea and terrestrial fibre, elevation and drainage against flood, water for cooling, scalable contiguous extent and clean multi-decade title. These are scored before a site is shortlisted.

How do you handle flood and CRZ risk?

We assess elevation, drainage and historical inundation and flag Coastal Regulation Zone status, since coastal sites near cable landings can carry extra compliance cost. Inland or elevated sites are weighed against the latency a coastal site offers.

Do you verify title for a multi-decade commitment?

Yes. A campus is a long-horizon investment, so title is verified over a long period and any multi-parcel assembly is checked parcel by parcel before the land is committed.
