Traditional data center construction optimizes for customization. Every tenant gets a bespoke environment tuned to their specific power density, cooling requirements, and network topology. The cost: $11.3M per MW and 18-24 months.
Modular construction makes the opposite trade. Standardized modules. Fixed form factors. Pre engineered power and cooling. The cost: $4.5-6.5M per MW and 90-120 days.
For AI compute workloads, the standardization penalty is surprisingly small. GPU clusters have predictable power profiles. Cooling requirements are well understood. Network topology follows established patterns. The workload is homogeneous enough that the flexibility of traditional construction adds cost without adding value.
The real engineering challenges in modular are different: thermal management in constrained enclosures, power distribution across module interconnects, and maintenance access in dense configurations.
Grand View Research projects the modular data center market will grow from $29B to $75.77B by 2030. At 17.2% CAGR, this is one of the fastest-growing segments in infrastructure. The growth is driven by a simple calculation: for standardized workloads at 1-10 MW scale, the speed and cost advantages of modular outweigh the flexibility advantages of traditional construction.
