Description
Chennai has rapidly emerged as India’s second-largest data centre hub after Mumbai, leveraging strategic coastal connectivity and robust infrastructure to attract major investments. The city now accounts for about 15% of India’s total data centre capacity, and is projected to cross 800MW over the 5-year forecast period. A combination of strengths, including multiple submarine cable landings, abundant skilled IT talent, relatively lower real estate costs and supportive state policies, is expected to drive Chennai’s data centre growth.
Chennai is largely hyperscaler-anchored, with edge presence for other clouds and a rising enterprise base led by BFSI, public sector, and content/CDN driving multi-tenant expansion. All major Indian data centre operators are present, alongside global entrants via joint ventures and private equity funding. Chennai’s data centre landscape features two primary clusters (Ambattur and Siruseri) which host over a dozen facilities, with at least a dozen more under development.
Chennai’s international connectivity is a key differentiator. The city is a vital subsea cable landing station for India, with new high-capacity systems reinforcing its status as a digital gateway. This low-latency connectivity to Asia-pacific and Europe, combined with Tamil Nadu’s pro-investment Data Centre Policy (2021), has made Chennai a strategic alternative to traditionally constrained hubs like Singapore. The Tamil Nadu government offers generous incentives such as power tariff subsidies, a 100% electricity tax waiver for five years, and stamp duty concessions. It also provides single window clearances, meaning developers can route key approvals through one coordinated approval process instead of approaching multiple departments separately. This helps speed up land acquisition and permitting, and supports more predictable provisioning of power and other utilities for data centre projects. Sustainability is a growing requirement and operators are signing large renewable energy power purchase agreements to meet hyperscale green mandates. Green-certified facilities comprise 25% of the current inventory.
Overall, Chennai offers a compelling proposition for data centre investors and hyperscalers where strengths like global connectivity, cost advantages, and growth momentum outweigh challenges such as power availability and climate risks. With demand fueled by cloud adoption, AI and digitalization, Chennai’s data centre market is poised for sustained double-digit growth through 2031.
This report is a key resource for service providers, investors and enterprises looking to understand the Chennai data centre landscape, evaluate expansion opportunities, or identify suitable partners. Structure Research now tracks DCAI markets across APAC, including Mumbai, Hong Kong, Jakarta, and Manila, alongside traditional hubs such as Singapore and Tokyo.
