India is rapidly becoming one of the world’s most promising destinations for data centre infrastructure. According to the Data Centre Construction Cost Index 2025 by Turner & Townsend, the country has not only emerged as a leading market in Asia but also offers one of the lowest construction costs globally—particularly in Mumbai.

Mumbai’s Competitive Edge

Mumbai stands out as one of the most cost-efficient cities in the world for building data centres. Construction costs in the city average around $6.64 per watt, placing it second-lowest among 52 global markets.

Electricity costs further enhance the city’s competitiveness, with rates hovering around 6.7 cents per kWh—significantly lower than many other major data centre hubs. This makes Mumbai a strategic location for both domestic and international operators looking to expand capacity while managing costs efficiently.

Untapped Capacity, Immense Opportunity

India currently accounts for about 20% of the world’s data generation, yet holds only 3% of global data centre capacity. This mismatch underscores a massive opportunity for growth.

Industry estimates suggest that India will require investments worth around $156 billion over the coming years to meet its growing digital infrastructure demands. With the government’s focus on digital transformation, cloud adoption, and AI-driven innovation, the momentum for large-scale data centre development is only expected to accelerate.

Challenges Beyond Costs

While India’s cost advantage is significant, experts caution that the next phase of growth will depend on overcoming several infrastructure hurdles.

1. Power reliability: Ensuring a consistent and sufficient power supply will be critical, especially as modern data centres become more energy-intensive with high-density GPU operations.

2. Cooling and sustainability: Efficient cooling systems and energy management will play a vital role in balancing cost and environmental goals.

3. Supply chain resilience: Developers will need to strengthen supply chains to manage the growing demand for specialised equipment and reduce lead times for construction.

Addressing these factors will determine how effectively India can translate its cost advantage into long-term competitiveness.

The Road Ahead for Investors

For investors, India presents a compelling opportunity with low costs, strong digital adoption, and a vast untapped market. Mumbai’s cost advantage makes it a gateway city for global players entering the region, offering both affordability and scale potential. However, success will depend on execution. Building resilient, sustainable infrastructure and ensuring operational continuity will be crucial in a sector that demands reliability above all else.
