NTT Data Group has announced a significant expansion of its India data center footprint with a ₹2,400 crore (US$288 million) investment in a new hyperscale campus near Bengaluru’s Kempegowda International Airport in Devanahalli. Spread over eight acres, the site will host three data centers forming a combined 100 MW campus, reinforcing Bengaluru’s role as a strategic digital infrastructure hub. The first building, Bengaluru 4A, is now operational.
“With this launch, our total investment in Bengaluru comes close to ₹4,000 crore, reflecting our long-term commitment to the region’s fast-growing ecosystem,” said Alok Bajpai, Managing Director, NTT India.
The new campus adds to NTT’s network of 22 operational data centers across India, including three existing facilities in Bengaluru.
First Building Live With 22.4 MW IT Load
The Bengaluru 4A building brings 22.4 MW of IT load, along with 3.2 MW dedicated to the data hall, forming part of the larger 100 MW design capacity across the campus.
The three facilities together are expected to provide 67.2 MW of usable IT load for hyperscalers, cloud providers and large enterprises.
NTT has yet to disclose anchor tenants or pre-leasing commitments, leaving visibility on utilization and ROI timelines unclear. However, the phased rollout is seen as a strategic hedge against market volatility in India’s rapidly growing data center sector.
Industry estimates indicate India’s data center capacity will expand from 0.9 GW in 2023 to 2 GW by 2026, driven by AI workloads, cloud adoption, and rising digital public infrastructure.
Open Access 2025 Enables Deep Renewable Energy Integration
One of the project’s key differentiators is its alignment with Karnataka’s Open Access Regulations 2025, which simplify renewable energy procurement by enabling:
streamlined grid access
energy banking
reduced regulatory overhead
flexibility for long-term power purchase agreements
This regulatory shift opens the door for 24×7 renewable energy PPAs, including solar-plus-storage and hybrid clean energy ecosystems.
“NTT’s Bengaluru campus will drive demand for round-the-clock clean energy solutions — a crucial step for lowering operational power costs while aligning with sustainability goals,” an industry expert noted.
The data center’s design includes high-efficiency cooling, energy-optimized layouts and sustainable infrastructure, making it suitable for AI and high-density compute loads.
Strengthening India’s Position in APAC Digital Infrastructure
NTT’s move comes as hyperscalers and AI companies ramp up compute capacity requirements, putting Bengaluru and Hyderabad among the world’s fastest-growing data center markets.
The location near the airport further positions the campus as a high-connectivity, low-latency hub for both domestic and global workloads.
Analysts expect NTT’s investment to act as a catalyst for:
new renewable energy projects
local storage and grid modernization
hyperscaler expansion in South India
increased availability of AI-ready capacity
As India’s digital infrastructure market enters an accelerated growth phase, NTT’s Devanahalli campus is set to become a critical node in the country’s compute and cloud backbone.
