India added approximately 900 MW of data centre capacity between 2022 and 2025, with another 1,500 MW committed for 2025-2027. This represents a $4-5 billion capital deployment cycle driven by two forces: the hyperscaler race (AWS, Microsoft Azure, Google Cloud all announcing Indian regions) and the AI training compute requirement, which is growing demand for GPU clusters at a pace traditional server demand never did.
The Power Problem Is the Real Bottleneck
A 100 MW hyperscale data centre consumes as much power as a mid-sized Indian city. The challenge is not just quantum — it is quality. AI workloads require 24×7 uninterrupted power with less than 4 minutes of downtime per year (Tier III specification). India's grid reliability is improving but not yet at this standard in most locations outside Mumbai and Chennai. Data centre operators are consequently building captive renewable energy arrangements — long-term PPAs with solar and wind developers with battery backup.
What Indian Listed Companies Benefit?
The directly listed beneficiaries are limited. Sterlite Power (now IndiGrid InvIT) benefits from transmission infrastructure. Schneider Electric and ABB India supply the critical electrical infrastructure. Polycab and KEI Industries supply the wiring harness.
- India data centre capacity: ~900 MW operational (2025)
- Pipeline: 1,500+ MW under construction (2025-27)
- Average rack density: rising from 10 kW to 25-30 kW for AI workloads
- Power cost: ₹6-8/kWh critical for competitiveness vs Singapore
- Key constraint: 24×7 RE supply at scale
🔍 BBS Insight
India's data centre story is real and large, but most of the value is captured by private companies. For listed market investors, the play is indirect — through power infrastructure (ABB India, Schneider Electric India), cabling (Polycab, KEI), and IT services companies winning cloud migration and managed services contracts from the same hyperscalers building these facilities. Do not confuse the infrastructure investment theme with listed equity opportunity without checking which companies actually have data centre revenue lines.
