Colt Mumbai 3 Data Center 64MW AI Factory Navi Mumbai

Status: Under Construction (Groundbreaking / Construction Commenced October 2026)   |   Location: Airoli-Mahape Industrial Corridor, Navi Mumbai, Maharashtra 400710, India

Project Overview

The Colt Mumbai 3 Data Center is a flagship 64 MW, AI-ready digital infrastructure development located within Colt Data Centre Services’ (Colt DCS) master-planned campus in Navi Mumbai, Maharashtra, India. The project forms part of a major US$1.7 billion joint venture between London-headquartered Colt DCS, backed by Fidelity, and Indian alternative asset owner RMZ. As the third data center building on the campus, Mumbai 3 expands the site’s planned computing infrastructure, bringing its operational site capacity to 86 MW and advancing development toward a full campus master plan of 148 MW. Its scale reflects the growing demand for high-capacity data center infrastructure in India’s expanding cloud and artificial intelligence markets.

The facility’s AI-ready design is intended to accommodate evolving computing requirements as enterprises, cloud providers, and technology companies deploy increasingly intensive workloads. AI applications can require high-density server configurations, substantial power delivery, and advanced cooling systems to maintain performance. Alongside AI computing, data center capacity supports enterprise applications, cloud services, digital platforms, and data processing across multiple industries. Mumbai 3’s 64 MW capacity represents a significant addition to the campus, while the broader 148 MW master plan provides a framework for continued expansion. Specific details about the building’s individual IT load allocation, cooling technologies, power sourcing, and commissioning timeline have not been provided in the supplied information.

Navi Mumbai’s role within the wider Mumbai metropolitan region makes the campus relevant to businesses seeking digital infrastructure in one of India’s principal commercial and technology markets. The partnership between Colt DCS and RMZ combines international data center expertise with an established Indian real estate and investment platform. As the third building within the campus, Mumbai 3 contributes to a phased development strategy that increases capacity while supporting longer-term growth. Its ultimate contribution to the market will depend on delivered capacity, energy infrastructure, network connectivity, and operational readiness. Nevertheless, the project represents a substantial expansion of AI-ready data center infrastructure in Navi Mumbai, supporting the region’s growing digital economy.
