The city of Kolkata in West Bengal is emerging as a key digital infrastructure and data centre destination in eastern India. With growing enterprise demand, government digitalisation, and connectivity to eastern and northeastern markets, Kolkata is attracting investments from operators such as ST Telemedia Global Data Centres, Nxtra by Airtel, and AdaniConneX. The region’s strong telecom backbone and cost advantages are driving rapid development of hyperscale and colocation facilities.

Data centres operate continuously with high electricity consumption driven by servers, cooling, and uptime requirements. Electricity is one of the largest operational costs. Rising tariffs, ESG mandates, and sustainability commitments from global cloud providers are pushing operators in Kolkata to switch to renewable energy procurement.
Companies are focusing on industrial electricity cost reduction, open access renewable energy, group captive solar and wind, and long-term corporate PPA renewable energy for data centres. Renewable sourcing helps stabilise tariffs, improve sustainability performance, and support global net-zero commitments.
