ST Telemedia Global Data Centres India has expanded its footprint in Chennai with the launch of a new data centre at its Siruseri campus, the company’s fourth facility in the city. The Siruseri site is being developed as a 45 MW AI-ready campus, with the first phase of 7.2 MW now operational. The launch is part of STT GDC India’s ₹4,200 crore investment commitment in Tamil Nadu to build next-generation, AI-ready digital infrastructure.
The new facility was inaugurated on 12 February by Tamil Nadu Chief Minister M.K. Stalin, as the state steps up efforts to attract large-scale data centre and cloud investments. STT GDC India already operates 40 MW of capacity at its Ambattur campus in Chennai and recently broke ground on STT Chennai 4 at the same site. Taken together, the company’s total development potential in Chennai now stands at nearly 130 MW, including existing operational capacity.
Supporting Hyperscalers and AI Workloads
The Siruseri campus has been purpose-built to support hyperscalers, cloud service providers, and enterprises as they scale AI and data-intensive workloads. As AI adoption accelerates and cloud demand grows, STT GDC India said the need for resilient, high-density, future-ready infrastructure is becoming critical for customers. Chennai’s coastal location, multiple submarine cable landings, reliable power infrastructure, and comparatively cost-effective real estate have helped position it as one of South Asia’s leading data centre hubs, rivaling traditional markets and outpacing several other cities in capacity addition.
The company recently signed a Memorandum of Understanding with the Government of Tamil Nadu, proposing investments of ₹4,200 crore to develop AI-ready data centre infrastructure in the state. The Siruseri expansion forms a key part of this plan, aimed at serving rising demand from hyperscalers, enterprises, and cloud service providers across AI, cloud, and digital transformation workloads.
Nationwide Expansion and IPO Plans
Beyond Chennai, STT GDC India is executing one of the largest expansion phases in its history. The company has signed MoUs with the governments of Karnataka, Maharashtra, Telangana, and Uttar Pradesh to build large-scale, AI-ready data centre campuses. New capacity is being developed across major digital corridors including Mumbai, Noida, Pune, Jaipur, Hyderabad, and Bengaluru to provide geographically diversified, high-availability infrastructure for customers in India’s key economic centres.
STT GDC India currently operates 30 data centres across 10 cities, with more than 400 MW of critical IT load capacity, making it one of India’s largest data centre platforms. The company said it continues to evaluate long-term strategic options to support future expansion, including a potential initial public offering targeted for the first half of 2027 to strengthen capital access and accelerate its nationwide growth plans.
Through sustained investments in AI-ready infrastructure and multi-city expansion, STT GDC India aims to position itself at the core of India’s cloud, AI, and enterprise transformation.
