Data center construction cost in the U.S. and Canada runs from about $8.9 million to $23.3 million per megawatt (MW) for all-in greenfield projects, according to Cushman & Wakefield’s 2026 development cost guide. That range excludes the chips and GPUs needed for AI workloads. Where your project lands depends mostly on power availability, land, redundancy level, cooling design, and location.
Quick Answer
- Per MW: about $8.9M to $23.3M for greenfield builds in the U.S. and Canada, per Cushman & Wakefield.
- Trend: that guide reports per-MW construction costs up about 21% since the late-2024 edition.
- Biggest cost driver: electrical systems, followed by cooling and mechanical systems.
- Higher resilience costs more: a Tier IV design needs more duplicated equipment than Tier III.
- AI-ready builds: high-density liquid cooling and heavy power loads push budgets toward the top of the range or beyond it.
Note: Published benchmarks differ by market, year, and what they include (shell only, fit-out, land, or IT equipment). Treat every figure here as a planning estimate and get contractor quotes for a real project.
Data Center Construction Cost per MW
Cost per MW of IT load is the most useful planning metric, because power and cooling infrastructure scale with capacity. A small enterprise room, a colocation hall, and a hyperscale campus can all be priced on the same basis.
| Build type | Planning view |
|---|---|
| Greenfield, U.S. and Canada (all-in) | About $8.9M to $23.3M per MW, excluding chips and GPUs (Cushman & Wakefield) |
| Brownfield or conversion | Often cheaper, because existing power, structure, and roads can be reused; savings depend on remediation and condition |
| Tier III versus Tier IV | Tier IV needs more redundant paths, so it costs more; the premium varies by design |
| AI or high-density | Higher electrical load and liquid cooling raise cost per MW |
What Drives Data Center Construction Costs?
Land and power
Access to grid power now often decides where a site can be built at all. Land price, utility interconnection, substation work, and wait times for transformers and switchgear can all add cost before the building itself starts. Secure utility commitments before you buy land.
Electrical and cooling systems
Electrical gear (switchgear, UPS, generators, distribution) is usually the largest cost block, and cooling (chillers, air handlers, liquid cooling) is typically the next. Industry rules of thumb often put electrical at roughly 40% to 45% of the build and cooling at 15% to 20%, but the real split depends on density and design.
Scale and redundancy
Every redundant power or cooling path adds equipment. Choosing N+1 or a Tier IV design raises the budget, while right-sizing capacity avoids paying for stranded, unused power.
Labor and supply chain
Skilled labor wages and long lead times for critical components were cited as drivers of the recent cost increase. Locking in equipment orders early can protect your schedule and price.
Is Greenfield or Brownfield Cheaper?
Brownfield sites usually have the cost edge, because you can reuse power, water, roads, and sometimes a building shell. Greenfield means buying land and building utilities and site systems from scratch.
- Reusing existing infrastructure can lower upfront cost.
- Existing utilities and permits can shorten the schedule.
- Budget for environmental testing and any remediation, which can erase the savings.
Retail Colocation vs. Wholesale: Which Costs More?
Retail colocation usually costs more per MW than wholesale. Retail halls fund multi-tenant power distribution, segmented cooling, extra security, and tenant-ready fit-out. Wholesale uses standardized designs for one large tenant, which trims scope. Ask for quotes that state exactly what each price includes.
How to Budget for a Data Center
- Set the target MW and tier. Everything else scales from these two choices.
- Secure power first. Confirm utility capacity and timing before committing to land.
- Separate the scope. Price land, shell, power, cooling, fit-out, and IT equipment as separate lines.
- Add contingency. Supply-chain swings and labor costs can move prices during construction.
- Use modular phases. Building capacity in stages can improve budget control; see the U.S. Department of Energy data center guidance on efficiency.
Frequently Asked Questions
How much does it cost to build a data center per MW?
Cushman & Wakefield’s 2026 guide puts all-in greenfield costs in the U.S. and Canada at about $8.9 million to $23.3 million per MW, excluding chips and GPUs. Actual cost depends on location, redundancy, and cooling.
What is the most expensive part of building a data center?
Electrical systems are usually the largest cost block, including switchgear, UPS, and backup generators. Cooling is typically the next largest, and AI workloads raise both.
Is a brownfield data center cheaper than greenfield?
Often yes, because existing power, structure, and roads can be reused. Remediation and condition issues can reduce or erase the savings, so inspect the site first.
Does a Tier IV data center cost more than Tier III?
Yes. Tier IV requires fully fault-tolerant, duplicated systems, which adds equipment and cost. The exact premium depends on the design and site.
