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. This development is a milestone reflecting the pace at which the venture has scaled just within 18 months of signing.

"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. Built with AI readiness at its core, the facility incorporates advanced cooling capabilities, including liquid cooling and enhanced power infrastructure to support high-density deployments. This enables customers to efficiently scale next-generation AI and high-performance computing workloads while maintaining operational resilience and efficiency," 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. This investment reinforces our commitment to building advanced data centre and AI infrastructure that meets global standards and supports the rapidly evolving demands of the digital economy," said Deepak Chhabria, President, RMZ Digital Infrastructure.

Mumbai 3 responds to growing demand for AI-ready data centre capacity in the region, where the rapid adoption of AI is driving requirements for larger deployments, higher rack densities and greater power capacity. With the data centre fully pre-let, the project will deliver critical AI-ready capacity to the Mumbai market while reinforcing Colt DCS and RMZ's commitment to India's growing digital infrastructure.

Mumbai 3 will join existing data centres Mumbai 1 and Mumbai 2 at the Navi Mumbai Campus, which currently supports large enterprise and cloud workloads. The campus has the potential to deliver up to 148MW of capacity at full development and, upon completion, Mumbai 3 will increase the site's operational capacity to 86MW.
