Global data center capacity grew from 42GW in 2023 to over 60GW in 2025. Goldman Sachs projects 122GW capacity by 2030. That means the industry is building more data center capacity in the next five years than it built in its entire prior history.
Conventional stick-built data center construction, with its 24–36-month design-permit-build schedule, cannot deliver at this rate. AI training clusters now consume hundreds of megawatts per deployment, and inference demand is scaling faster than anyone forecast even eighteen months ago.
The response is prefabricated modular data center construction. Power distribution, cooling plant, and IT infrastructure are moving from the job site to factories. Highly modularized projects achieve 30–50 percent schedule improvement, bringing delivery from 24–36 months down to 12–16 months.
Some operators report sub-nine-month timelines for pre-engineered deployments. But the engineering challenges of this change run deeper than speed. Modular construction completely changes how electrical systems are designed, tested, and coordinated — and the standards framework has not kept pace.
