The city of Chennai in Tamil Nadu has become one of India’s fastest-growing data centre and digital infrastructure hubs. With strong subsea cable connectivity, a stable power ecosystem, and proximity to Southeast Asian markets, Chennai hosts hyperscale and colocation facilities from operators such as ST Telemedia Global Data Centres, Nxtra by Airtel, and CtrlS Datacenters. The region’s strong IT and enterprise ecosystem continues to drive rapid data centre expansion.
Data centres are highly energy-intensive due to continuous uptime requirements, cooling systems, redundancy, and scalability. Rising electricity tariffs in Tamil Nadu, sustainability commitments from global cloud providers, and carbon neutrality targets are driving data centre operators in Chennai to switch to renewable energy sourcing.
Today, 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 procurement helps reduce operating costs, improve ESG performance, and ensure long-term energy price stability.
Why Data Centres in Chennai Are Switching to Renewable Energy
