Tata Power Trading Company Limited, a wholly owned subsidiary of Tata Power, in partnership with Singapore-based Keppel Limited’s Infrastructure Division, has announced a large-scale Cooling-as-a-Service deployment at Intellion Park in Chennai — one of India’s largest and most sustainability-focused commercial campuses — under a 15-year contract that the partners describe as a blueprint for how modern commercial real estate will manage energy going forward.
The project, awarded by Infopark Properties Limited, a unit of Tata Realty and Infrastructure Limited, covers a total installed capacity of 12,100 tonnes of refrigeration — making it one of the largest CaaS deployments in India’s commercial real estate sector. The system is scheduled to go live in October 2026 and is expected to reduce the facility’s overall energy consumption by approximately 20%.
What Cooling-as-a-Service actually means
CaaS is a subscription or performance-based model where the customer — in this case Tata Realty — pays for cooling outcomes rather than owning and operating the cooling infrastructure itself. There is no upfront capital expenditure on the chiller plants, cooling towers or associated equipment. Instead, Tata Power and Keppel own, operate and maintain the infrastructure over the contract period, optimising performance and absorbing the risk of technology obsolescence.
At the core of this deployment is an AI- and ML-driven Operations Nerve Centre, a patented technology developed by Keppel, which provides real-time monitoring, predictive analytics and dynamic performance optimisation across the facility. The ONC continuously adjusts cooling output based on occupancy, weather, load patterns and equipment health — ensuring energy is never wasted and system reliability is maintained.
Intellion Park and the broader Tata Realty ambition
Intellion Park Chennai spans 25.27 acres across SEZ and non-SEZ zones in Taramani’s IT corridor and is already India’s first IFC EDGE Net Zero carbon campus. The park already sources green power from Tata Power, and the addition of CaaS now creates what the partners describe as a fully integrated low-carbon energy ecosystem — renewable power on the supply side, intelligent cooling optimisation on the demand side.
Over time, the partnership is expected to extend to the broader HVAC system including low-side air-handling units, unlocking additional efficiency gains and enabling a more holistic approach to energy management across the campus.
Tata Realty is targeting a portfolio expansion to approximately 30 million sq ft over the next five years and has set a net-zero goal by 2045. The Intellion commercial brand currently has over 9.4 million sq ft of developed space and 10.2 million sq ft under development, housing over 102 tenants including Fortune 500 companies and multinationals.
What the three leaders said
Dr. Praveer Sinha, CEO and Managing Director of Tata Power, said India’s commercial real estate sector is a fast-growing source of energy demand driven by rising cooling needs, and that the Intellion Park partnership demonstrates how integrated solutions combining clean energy and advanced cooling can accelerate decarbonisation. He said Tata Power is positioned to scale these capabilities through Utilities-as-a-Service and Energy-as-a-Service offerings across real estate, data centres, global capability centres and commercial-industrial customers.
Sanjay Dutt, MD and CEO of Tata Realty, described the agreement as a fundamental shift from ownership-led infrastructure to a performance-driven, service-led model, calling it not just a cooling contract but a blueprint for how forward-looking organisations collaborate to deliver better operational outcomes and long-term environmental value.
Cindy Lim, CEO of Keppel’s Infrastructure Division, said cooling is no longer a standalone utility but is becoming core to how the built environment is designed, operated and decarbonised. She confirmed that Tata Power and Keppel have jointly secured additional CaaS projects beyond Intellion Park and are building a pipeline spanning commercial real estate, data centres, advanced manufacturing and district cooling systems for master-planned cities and airports.
The macro context
The International Energy Agency projects India will become the world’s largest consumer of space cooling by 2050 — a trajectory driven by urbanisation, rising incomes and intensifying summers. Against that backdrop, the CaaS model — which removes the capital barrier to deploying high-efficiency cooling while ensuring continuous technology upgrades and performance accountability — is positioned as one of the most practical tools available for India’s built environment to manage its energy transition without sacrificing occupant comfort or operational efficiency.
