## Summary

Colt Data Centre Services (Colt DCS) and RMZ, an Indian real assets platform, announced on October 15, 2026, that construction has started on **Mumbai 3**, a 64MW AI-ready data center in Navi Mumbai. The facility is fully pre-let, with its first hyperscale customer already signed, and marks a milestone in the joint venture’s rapid scaling—just 18 months after its 2024 launch.

The $1.7 billion partnership aims to develop **250MW** of capacity across Mumbai and Chennai. Mumbai 3 will join existing facilities at the Navi Mumbai Campus, boosting its operational capacity from **148MW** to **86MW** upon completion. Designed for high-density AI workloads, the center features hybrid cooling (air and liquid-to-chip), a **220kV GIS substation**, and carrier-neutral connectivity. Both companies emphasize sustainability, with **100% renewable energy** and a closed-loop cooling system to minimize wastewater. The project will create **over 700 jobs** and support local suppliers.

Pratap Mane (Colt DCS India) and Deepak Chhabria (RMZ Infrastructure) highlighted the facility’s role in meeting India’s growing AI and cloud demands, citing scalability, resilience, and speed as key advantages.
