Colt DCS and RMZ Break Ground on AI‑Ready Mega Data Centre in Mumbai, Driving $1.7B Digital Infrastructure Expansion

• Part of a $1.7 billion investment under Colt DCS and RMZ's joint venture to develop data centre capacity across India. 
• Signs its first hyperscale client for Mumbai 3
• AI-ready facility delivering 64MW upon completion, powered entirely by renewable energy
• Hybrid cooling design incorporating a closed-loop cooling system to enable near-zero wastewater. 
• Expected to create more than 700 jobs across construction and operations

Colt Data Centre Services (Colt DCS), a global provider of AI-ready, hyperscale and large enterprise data centres, and RMZ, India's largest privately owned real assets platform, today announced the commencement of construction of its third data centre in the city (Mumbai 3), an AI-ready facility located at the operator's Navi Mumbai Campus that will deliver 64MW upon completion.

Mumbai 3 is being developed as part of Colt DCS and RMZ's joint venture (JV), announced in 2024, to invest $1.7 billion in the Indian data centre market. Ground preparation began in December 2025, and construction is now underway following the signing of the facility’s first hyperscale customer.

“The nature of data centre demand is evolving rapidly, with customers requiring larger deployments, higher rack densities and infrastructure capable of supporting increasingly intensive AI workloads. Mumbai 3 is designed to address these needs, further strengthening our Navi Mumbai Campus as a scalable and future-ready digital infrastructure platform,” said Pratap Mane, Country Head DCS, India.

“The next wave of digital growth will be driven by infrastructure that brings together scale, resilience, and speed to market. At Mumbai 3, we are developing a future-ready campus designed to enable hyperscalers and neo-cloud providers to scale seamlessly as their capacity and computing needs evolve,” said Deepak Chhabria, President, RMZ Digital Infrastructure.

Built for AI Deployments

Mumbai 3 has been designed to support AI workloads and high-density compute deployments, delivering 64MW of secured contracted power, supported by a hybrid cooling architecture that combines traditional air cooling with direct liquid-to-chip cooling. The facility will also benefit from a 220kV GIS substation located on campus, providing high levels of resilience and scalability, alongside carrier-neutral connectivity with access to high-capacity fibre routes.

Sustainable by Design, Creating Local Opportunity

• Operates using 100% renewable energy
• Closed-loop cooling system enabling near-zero wastewater
• Expected to create more than 700 jobs across construction and operations
• Supports local suppliers, contractors, and service providers

Joint Venture Commitment

As part of the JV, both organisations have committed to develop 250MW of data centre capacity across Mumbai and Chennai. The partnership brings together Colt DCS' global data centre expertise with RMZ's over two decades of experience in developing, owning and operating high-quality infrastructure in the Indian market.
