West Bengal has cleared the way for allocating 10 acres in Kolkata for a proposed Tier-3 data centre, adding a major digital-infrastructure project to the city’s expanding technology landscape. The move follows the opening of a large technology and AI facility in New Town and could deepen Kolkata’s role in India’s digital economy, while also placing greater demands on land, electricity, cooling and supporting urban infrastructure.
The proposed Kolkata data centre is linked to Larsen & Toubro’s wider expansion in West Bengal. The state government confirmed support for the additional land request during the inauguration of the company’s new Global Delivery and AI Competency Centre in New Town on August 27. The request had reportedly been submitted to the state administration earlier this year.The development comes as New Town’s Bengal Silicon Valley Tech Hub continues to attract technology investment. The newly opened campus covers roughly 7.5–8 lakh square feet across two buildings and currently has capacity for around 5,800 professionals. The wider facility is planned for significant expansion, potentially supporting up to 25,000 workers over time.For Kolkata, the significance goes beyond another corporate campus. Data centres form part of the physical backbone of cloud computing, artificial intelligence, digital payments and online public services. A Tier-3 facility is designed with redundant infrastructure and multiple distribution paths so planned maintenance can take place without interrupting operations.
That reliability, however, comes with an urban resource cost that needs careful planning. Data centres require substantial and dependable electricity, cooling systems, backup infrastructure and, depending on the technology adopted, water. India’s data-centre capacity has already risen from about 375 MW in 2020 to around 1,500 MW by 2025, increasing the importance of energy efficiency and resource planning as new facilities are added.For Kolkata, the next stage should therefore be judged not only by investment or employment numbers, but by how efficiently new digital infrastructure integrates with the city. Reliable grid connections, efficient cooling, lower-water technologies, renewable power procurement and resilient site planning can reduce pressure on public resources while improving long-term operating security.The Kolkata data centre proposal also raises a broader land-use question as New Town expands. Large technology projects can generate skilled employment and supporting economic activity, but their urban value depends on how well transport, utilities, drainage and surrounding neighbourhoods keep pace.
The immediate next step is the detailed development and approval process. Its outcome will show whether Kolkata can turn digital expansion into durable economic opportunity while keeping resource use, infrastructure resilience and the wider needs of citizens firmly within the planning equation.
