Kolkata Green Infrastructure Push Gains New Momentum
Kolkata is emerging as a potential hub for two infrastructure trends that are increasingly converging across India: data centres and low-carbon energy. Recent proposals for large digital facilities, alongside work on green hydrogen feasibility in the wider Damodar Valley, point to a changing investment landscape for West Bengal. The opportunity is significant, but so are the demands on land, electricity, water and environmental planning.
The state already has a policy framework for green hydrogen and ammonia, including provisions aimed at supporting production, storage and distribution infrastructure. The policy also identifies hydrogen as a potential route for lowering emissions in industrial sectors such as steel.At the same time, Kolkata and its surrounding urban region are being positioned for greater digital infrastructure investment. West Bengal’s existing data-centre policy had targeted substantial expansion of capacity, while New Town and the Bengal Silicon Valley technology hub have been identified as important locations for future facilities. A planned submarine cable landing station at Tajpur could further strengthen the state’s digital connectivity.Private investment proposals are already adding weight to that shift. Larsen & Toubro has been reported to be planning a roughly ₹2,000-crore, 13 MW data centre in Kolkata, alongside further investment in its New Town technology operations. The Centre has also been seeking greater participation from major technology companies in West Bengal’s data-centre and research ecosystem.
For Kolkata, however, expanding digital infrastructure cannot be assessed only through investment figures. Data centres require reliable electricity and substantial cooling systems, while hydrogen projects need dedicated land, renewable power, water and safety infrastructure. Urban planners say the location and design of such projects will therefore matter as much as their headline investment value.The water question is particularly important. Large industrial and digital facilities can place additional pressure on regional water systems unless treated or recycled water is prioritised. West Bengal’s green-hydrogen policy already provides for infrastructure covering production, storage and transportation, creating an opportunity to integrate resource efficiency into project planning from the outset.The wider Damodar Valley also offers a potential industrial testing ground. The Damodar Valley Corporation initiated a techno-commercial feasibility exercise for a green hydrogen and carbon-capture project covering parts of West Bengal and Jharkhand, although the tender was subsequently cancelled for administrative reasons.
Kolkata’s next phase of infrastructure growth will therefore depend on whether new digital and energy projects can be integrated with existing urban systems. For citizens, the measure of success will extend beyond capital committed: dependable power, responsible water use, skilled employment and lower environmental costs will determine whether this investment translates into durable urban value.
