You should budget about $7 million to $12 million per MW to build a modern data center, or roughly $600 to $1,100 per square foot overall. Your actual cost depends mostly on power availability, land, redundancy level, and MEP scope, with electrical systems taking 40% to 45% of spend and cooling adding 15% to 20%. Brownfield projects can trim costs by 10% to 15%, while Tier IV and AI-heavy builds can push budgets far higher as complexity increases.

What Is Data Center Cost Overall?
Data center cost is driven by power density, redundancy, and scale, so your total budget can vary sharply by design target. You’ll usually see initial build costs around $600 to $1,000 per square foot, while total development often lands between $625 and $1,135 per gross square foot.
From there, your cost structure gets more technical. Electrical systems typically consume 40% to 45% of total spend, making power architecture your biggest budget lever. Cooling adds another 15% to 20%, so thermal design directly shapes both upfront outlay and long-term operating expenses.
If you pursue higher resilience, Tier IV facilities generally cost 25% to 40% more than Tier III because you’re paying for deeper redundancy. At the high end, large campuses can surpass $2 billion, and flagship builds have reached $5 billion.
What Is Data Center Cost per MW?
When you benchmark by IT load, data center construction costs typically land around $7 million to $12 million per MW. That’s a more precise planning metric than square footage alone.
That range shifts with location, power density, and cooling technology. If you’re developing a greenfield site, expect that same $7 million to $12 million per MW band. Brownfield redevelopment often compresses to roughly $7 million to $8 million per MW.
Once you move into high-density deployments, costs climb fast. AI infrastructure can push beyond $20 million per MW because advanced cooling, redundancy, and higher electrical throughput all raise capital requirements significantly.
Evaluating energy efficiency and modular design early can help. Prefabricated approaches won’t eliminate cost pressure, but they can improve predictability, shorten delivery schedules, and give you tighter control over per-MW economics.
What Is Data Center Cost per Square Foot?
Per-megawatt pricing gives you the best read on infrastructure intensity, but cost per square foot still matters for early budgeting, site comparison, and shell-versus-fit-out analysis.
You can expect data center construction costs to run about $600 to $1,100 per gross square foot, with average total development costs landing around $625 to $1,135 per gross square foot.
If you’re isolating the shell, powered shell costs typically range from $105 to $235 per gross square foot.
For full improvements, plan on roughly $520 to $900 per gross square foot for the specialized build-out.
Land now averages about $5.59 per square foot, although parcels above 50 acres have climbed 23% year over year.
These benchmarks help you pressure-test financing assumptions, compare sites faster, and maintain capital control before you commit to a final program.
Which Factors Drive Data Center Costs?
Data center costs move first with land and power. Site prices, utility access, and electrical systems consume a large share of the budget before you add a single server rack.
MEP and cooling systems compound that spend quickly. Generators, PDUs, HVAC, and liquid cooling can materially increase cost per square foot and cost per megawatt.
As you scale capacity, redundancy targets and power density push development costs even higher, making scale and resiliency two of the most important variables in the budget.
Land And Power
| Cost Driver | 2024 Signal |
|---|---|
| Land | $5.59/sf average |
| Large parcels | +23% YoY |
On greenfield developments, expect $7 million to $12 million per megawatt, with local land and grid conditions driving the spread. Electrical systems alone absorb 40% to 45% of total project cost, so power access is one of the biggest determinants of whether your capital works efficiently. Buying land without secured utility commitments often forces added spending before operations can scale.
MEP And Cooling
Two systems dominate this layer of spend: MEP and cooling.
MEP systems alone often absorb 30%–50% of total project cost, with electrical infrastructure driving the largest share. UPS systems, switchgear, and backup generators typically consume 40%–45% of the full budget, so MEP optimization directly affects both upfront capex and long-term operating costs.
Cooling infrastructure adds another 15%–20%, covering chillers, CRAC units, controls, and distribution. As rack power density rises, hitting your cooling efficiency target gets harder and more expensive.
AI deployments intensify that pressure because liquid cooling often becomes necessary, increasing design complexity, installation effort, and commissioning cost. Engineering thermal performance and electrical resilience with precision from day one is the best way to control costs in this area.
Scale And Redundancy
Scale determines how efficiently you deploy capital. Redundancy determines how much infrastructure you must duplicate. Together, these two variables set the cost curve for nearly every data center build.
You’ll typically see construction costs from $600 to $1,100 per gross square foot, while greenfield development runs $7 million to $12 million per megawatt depending on redundancy tier. Choosing N+1 or pursuing Tier IV resilience raises your budget fast; Tier IV can cost 25% to 40% more than Tier III.
Stranded capacity is a real risk at scale. Since electrical systems consume 40% to 45% of total cost and HVAC adds 15% to 20%, every duplicated path compounds capital requirements. Right-sizing scale and redundancy protects uptime without locking up excess capital.
Is Greenfield or Brownfield Cheaper?
Which option is cheaper depends on how much existing infrastructure you can reuse, but brownfield sites usually have the cost edge.
Brownfield redevelopment can cut total costs by 10% to 15%, with average build costs around $7 million to $8 million per megawatt. Greenfield projects usually land between $8 million and $12 million per megawatt because you must buy land and build utilities, access, and site systems from scratch.
- You save upfront by reusing power, water, roads, and sometimes buildings.
- You compress timelines because utilities and some approvals may already exist.
- You must still price environmental testing and remediation into your model.
Brownfield often wins on pure economics, but poor due diligence can erase those savings quickly. Disciplined site assessments and contingency budgeting are essential before you commit.
Retail vs. Wholesale: Which Costs More?
Retail colocation builds cost more than wholesale. Retail usually lands around $16.3 million per megawatt and $2,200 per square foot, versus roughly $12 million per megawatt and $1,050 per square foot for wholesale.
That gap comes from infrastructure complexity, not inefficiency. When you build retail, you fund multi-tenant power distribution, segmented cooling, security layers, meet-me rooms, and tenant-ready fit-outs. You’re paying for tenant flexibility and immediate usability, which raises capital intensity.
With wholesale, you gain standardized design, a single large tenant, and cleaner operational efficiency. Reduced customization compresses construction scope and lowers unit costs.
Wholesale usually wins on raw construction economics. If you need turnkey delivery and the ability to serve multiple customers, retail costs more because you’re paying for that optionality upfront.
