Chennai data centers: 25 facilities and colocation prices
Compare Chennai data centers and request like-for-like quotes
Coloprice tracks 25 Chennai data center facilities from 17 operators. 17 are operational, 6 are under construction and 2 is announced. Facilities with a published figure total approximately 899+ MW, but pipeline capacity is not the same as commissioned and commercially available IT load.
Chennai serves enterprise, cloud and subsea-connectivity demand across southern India. Compare the exact facility and phase for live power, carrier access, cloud on-ramps, rack density, cooling, resilience evidence and delivery date rather than treating every announced campus or operator brand as equivalent.
For a commercial comparison, give every provider the same rack count or committed kW, density, redundancy, carrier and cloud requirements, compliance scope, target go-live date, contract term and expansion rights. Require capacity, electricity, cross-connects, setup, remote hands, fit-out and annual escalation to be itemized.
- 9 tracked Chennai facilities are marked AI-ready; confirm the available density and cooling scope for the proposed hall.
- Separate operational supply from construction-stage and announced capacity.
- Confirm whether published MW covers one building, one phase or the full planned campus.
- Treat operator Tier claims separately from independently documented certification evidence.
- Normalize all quotes to the same committed kW, term and delivery schedule.
