NTT BLR4: 100MW Hyperscale Data Center Campus in Bengaluru
Status: Active / Phase 1 Live & Operational (Tracking June 2026 Launch) | Location: 5JVV+8VF, Bengaluru, Shettigere, Karnataka 562110
Project Overview
The NTT DATA Bengaluru 4 Data Center Campus, designated as the BLR4 Campus, is a premier high-density digital infrastructure asset positioned within Bengaluru's booming international innovation corridor. Officially launching its first operational phase on June 13, 2026, under the leadership of Country Managing Director Vimal Kaw, the mega-campus represents a massive expansion of NTT DATA’s global hyperscale platform. It is custom-built to handle the intense workload scaling required by regional enterprises, deep cloud migrations, and modern artificial intelligence application clusters.
Unveiled to the public in mid-June 2026 with its first massive building (BLR4A) actively delivering 22.4 MW of critical IT load, the master-planned campus will ultimately feature three dedicated, high-efficiency data center facilities: BLR4A, BLR4B, and BLR4C. Situated strategically near the Kempegowda International Airport, the facility effectively insulates hyperscale tenants from regional speed-to-market and transmission limits. By deploying a massive, dedicated high-voltage utility connection right onto the campus grounds, the site provides a highly secure, carrier-neutral ecosystem engineered to anchor dense accelerated computing matrices with ultra-low latency fiber backhauls.
