Quick answer
Edge data centres need about 0.5–2 acres, enterprise and colocation sites usually need 2–10 acres, and hyperscale campuses typically need 10 to 100+ acres. The real driver is power: plan land around your target megawatts, cooling type, generator yard and setbacks.
Key takeaways
- Size land around MW, not floor area
- Generators, substations and setbacks use lots of space
- Hyperscale buyers should secure expansion rights early
Rule-of-thumb land sizes
Edge: 0.5–2 acres. Enterprise: 2–5 acres. Colocation: 3–10 acres. Hyperscale: 10–100+ acres across phases.
What uses the space
Besides data halls you need a substation, transformer yards, generator yards, fuel storage, cooling plant, roads, parking, security setbacks and green-area rules set by the state.
Vertical vs horizontal designs
In dense cities like Mumbai, multi-storey designs fit more MW per acre. In outer locations, single or two-storey layouts are cheaper to build.
