## Mumbai 3 Reaches Construction After First Hyperscale Client

Ground preparation for Mumbai 3 began in December 2025, and construction is now underway following the signing of the facility's first hyperscale customer. The facility is fully pre-let and will join Mumbai 1 and Mumbai 2 at the Navi Mumbai Campus, which currently supports large enterprise and cloud workloads. Upon completion, Mumbai 3 will increase the site's operational capacity to 86MW, and the campus has the potential to deliver up to 148MW at full development.

[Third News](https://third-news.com/article/17ad4de6-c85a-11f1-9cf8-9ca3ba08e13f) reported that the project targets 64MW of power and that the venture plans 250MW across Mumbai and Chennai. As part of the joint venture, Colt DCS and RMZ have committed to develop 250MW of data centre capacity across Mumbai and Chennai.

RMZ is India's largest privately owned real assets platform, founded by Raj Menda and Manoj Menda in 2002 and headquartered in Bengaluru. The partnership brings together Colt DCS' global data centre expertise with RMZ's more than two decades of experience developing, owning and operating infrastructure in the Indian market.

"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," said Pratap Mane, Country Head DCS, India.
