India's Digital Infrastructure Set for Major Expansion with 30% Data Centre Growth in 2026
India's rapidly expanding digital backbone is poised for another significant leap forward, with the country's total data centre capacity expected to grow by nearly 30% in 2026. According to a comprehensive report by CBRE Group, Inc., this expansion will add approximately 500 megawatts (MW) of fresh capacity across major urban centers throughout the nation.
Geographical Spread Beyond Traditional Hubs
While Mumbai continues to dominate India's data centre landscape, accounting for over half of the country's total capacity due to its superior connectivity and reliable power infrastructure, the growth momentum is now spreading to emerging cities. Ahmedabad, Visakhapatnam, Patna, and Bhopal are among the urban centers witnessing increased data centre development. This geographical diversification is primarily driven by three key factors: the nationwide expansion of 5G networks, growing demand for low-latency services, and stringent data localisation norms that require certain types of data to be stored within India's borders.
This expansion represents a crucial step in improving digital access beyond metropolitan areas, bringing faster and more reliable internet services to previously underserved regions. The development comes on the heels of a record-breaking 2025, when India's total installed data centre capacity surpassed 1,700 MW. That year saw an unprecedented addition of 440 MW—more than 160% higher than the previous year's growth figures.
Understanding Data Centres and Their Impact
In simple terms, data centres serve as the fundamental backbone of the internet ecosystem. These large-scale facilities store and process virtually all digital information, from everyday WhatsApp messages and UPI payment transactions to Netflix streaming content and critical government databases. The more capacity India develops, the faster, safer, and more reliable these essential services become for everyday users across the country.
For ordinary citizens, the surge in data centre infrastructure directly impacts daily life in multiple ways:
- Enabling faster internet speeds and smoother application performance through reduced latency (the delay in data transfer)
- Improving reliability of essential services including banking, UPI payments, e-governance platforms, and telemedicine applications
- Enhancing data security through localisation requirements that keep sensitive information within national borders
Economic Impact and Investment Landscape
The data centre sector is generating substantial employment opportunities across multiple domains, including construction, engineering, information technology, and facility management. Furthermore, increased scale and competition may lead to reduced long-term costs for cloud services, benefiting both businesses and individual consumers.
The industry is witnessing massive investor interest, with total investment commitments reaching $126 billion by the end of 2025. Projections indicate this figure will rise by approximately 45% to cross $180 billion in 2026. Industry experts note that data centres are increasingly being treated as a mainstream asset class, making them a top investment priority throughout the Asia-Pacific region.
"India's data centre story is no longer about potential but about execution at scale," emphasized Anshuman Magazine of CBRE, highlighting the strong participation from foreign investors in this rapidly growing sector.
Sustainability Challenges and Government Support
Despite the promising growth trajectory, rising power demand presents a significant challenge for the expanding data centre industry. This has prompted a notable shift toward renewable energy solutions. India added a record 44.5 gigawatts of renewable capacity in 2025, providing crucial support for the sustainable growth of data centre operations.
The government has further bolstered the sector through strategic measures in the Union Budget 2026-27, including:
- A tax holiday extending until 2047 for foreign cloud companies utilizing India-based infrastructure
- A 15% safe harbour margin to ease tax-related disputes and uncertainties
- Capital support ranging from 25% to 35% for green data centres implementing environmentally sustainable practices
Broader Implications for India's Digital Future
The rapid expansion of data centre infrastructure is central to India's evolving digital economy, serving multiple strategic purposes:
- Strengthening digital sovereignty by reducing dependence on foreign data storage facilities
- Boosting innovation and supporting startup ecosystems through improved digital infrastructure
- Enhancing global competitiveness in the technology sector
- Delivering faster, safer, and more reliable digital services to citizens across the country
This comprehensive development represents a crucial milestone in India's journey toward becoming a global digital powerhouse, with data centres serving as the critical physical infrastructure supporting the nation's technological ambitions.
