How much does it cost to build a data center per megawatt?

The global benchmark is roughly $11.3M per MW of critical IT load in 2026, up from about $10.7M in 2025. The US averages $10-13M/MW, Malaysia mid-range is $9.6M/MW (high of $12M), and Vietnam is the regional low at $5.7-8.7M/MW. AI-optimized facilities with liquid cooling can exceed $20M/MW.

How much does a 100 MW data center cost?

At 2026 benchmarks, a 100 MW hyperscale campus costs roughly $1.0-1.3 billion in the US and $700M-1.0B in most of Southeast Asia, excluding land banking beyond the initial phase and excluding tenant IT equipment. TikTok's approved Thailand program (THB 842B, ~$25B) illustrates multi-campus scale.

What is the biggest cost in data center construction?

Electrical systems — switchgear, transformers, UPS, generators, distribution — account for 40-45% of construction cost, sometimes up to 50%. Mechanical/cooling adds 15-20%, building fit-out 20-25%, and land plus shell only 15-20%. A data center is an electrical machine with a building around it.

How long does it take to build a data center?

A single-building 20-60 MW facility typically takes 18-30 months from groundbreaking to commissioning, but grid connection is now the gating item: interconnection queues in constrained markets add 2-4+ years. Modular and prefabricated approaches can compress construction to 12-18 months.

How much does data center land cost?

Land is usually under 5% of total project cost, but siting drives everything else. Powered land in Northern Virginia has traded above $1M per acre, while Southeast Asian industrial estates run $100-400k per acre. The scarce asset is grid capacity, not acreage — 'powered land' with secured interconnection sells at multiples of raw land.

What are data center operating costs?

Electricity is 50-70% of opex; at $0.08/kWh, a 10 MW facility at PUE 1.4 consumes roughly $9.8M of power per year. Staffing, maintenance contracts, water, insurance, and property tax typically add $1-2M per year per 10 MW. Efficient PUE directly converts to operating margin.

Why are AI data centers more expensive to build?

Rack densities of 80-150 kW require liquid cooling loops, heavier electrical distribution, reinforced floors, and larger back-of-house plant per square meter. Turner & Townsend and market cost guides put AI-optimized builds at $15-20M+ per MW versus $10-11M for air-cooled cloud facilities.

How Much Does a Data Center Cost to Build in 2026?

Building a data center costs $9-13M per MW in the US in 2026, $8-12M in Southeast Asia, and $6-9M in Vietnam. AI-ready facilities exceed $15-20M/MW.

Building a data center in 2026 costs roughly $11.3 million per megawatt of critical IT load at the global benchmark — about $10-13M/MW in the United States, $8-12M/MW across most of Southeast Asia, and $6-9M/MW in Vietnam, the region’s cheapest market. AI-optimized facilities with liquid cooling run $15-20M+/MW. These figures cover shell, power, and cooling infrastructure; tenant IT hardware is additional.

Key takeaways

Global shell-and-core benchmark: ~$10.7M/MW in 2025, trending to ~$11.3M/MW in 2026 (+6% forecast), per Axis Intelligence compilations of industry indices.
Cost inflation persists: Turner & Townsend reports cost-per-watt for a traditional air-cooled cloud facility rose 5.5% YoY in 2025; APAC costs rose ~10%, fastest of any region.
Electrical is the budget: 40-45% of construction cost is electrical systems; land and shell are only 15-20%.
Vietnam is the SEA cost floor: $5.7-8.7M/MW (mid-range $7.2M), per Cushman & Wakefield. Malaysia mid-range is $9.6M/MW with a $12M high.
Grid connection, not construction, is the schedule risk: building takes 18-30 months; interconnection in constrained markets can take longer than the building itself.
Opex is dominated by power: 50-70% of operating cost is electricity; PUE improvements flow straight to margin.

A worked example: a 40 MW Tier III facility in Bangkok at $8.5M/MW is a ~$340M project. The same facility in Northern Virginia at $12M/MW is $480M — a 41% spread driven mostly by labor, imported-equipment logistics, and design standards rather than land.

Where the money goes: cost breakdown

Category	Share of construction cost	What it covers
Electrical systems	40-45%	Substations, switchgear, transformers, UPS, batteries, generators, busway/PDUs
Building fit-out	20-25%	White space build, raised floor/slab, fire suppression, security, BMS
Mechanical / cooling	15-20%	Chillers, CRAH/CRAC or liquid loops, cooling towers, pumps, piping
Land + shell & core	15-20%	Site, structure, envelope

Breakdown per Encor Advisors and TrueLook; electrical alone is frequently quoted at $280-460 per square foot, with mechanical adding $125-215/sq ft.

The practical implication: a data center is an electrical procurement project. Transformer and switchgear lead times — quoted at 12-24+ months through 2025-2026 — set the critical path, and early equipment reservation is now standard practice among experienced developers.

Capex stack beyond construction

Grid connection: interconnection studies, substation contributions, and transmission upgrades range from low single-digit $M to $50M+ for large campuses in constrained grids.
IT equipment (tenant side): not in the $/MW figures above. A single NVIDIA GPU rack can exceed $3M; a 10 MW AI hall can carry $300-500M of IT load — often 3-5x the building cost.
Commissioning and certification: Level 1-5 commissioning plus optional Uptime Institute Tier certification, typically 1-3% of project cost.

Operating costs

For a 10 MW facility at PUE 1.4 and $0.08/kWh:

Opex line	Annual cost
Electricity (10 MW IT × 1.4 PUE × 8,760 h × $0.08)	~$9.8M
Staffing (ops, security, facilities; 15-25 FTE)	$1.5-2.5M
Maintenance contracts (gensets, UPS, chillers)	$0.8-1.5M
Water, insurance, property tax, misc	$0.5-1.5M
Total	~$12.6-15.3M/year

Electricity’s 60-70% share explains why operators chase low-tariff markets and why every 0.1 of PUE on a 10 MW site is worth roughly $700k per year at $0.08/kWh. It also explains regulatory direction: Thailand’s BOI ties its longest tax holidays to power-usage efficiency, and Malaysia has restricted non-AI approvals outright to protect its grid.

Timelines

Phase	Duration	Notes
Site selection + land	3-12 months	Powered land shortcuts this
Grid interconnection	12-48+ months	Runs in parallel; the gating item in NoVa, Dublin, Singapore
Permits + design	6-12 months	Faster in Thai/Malaysian industrial estates with pre-zoning
Construction	12-24 months	18-30 months typical for 20-60 MW single buildings
Commissioning	2-4 months
Total (greenfield)	~24-48 months	Modular/prefab compresses construction to 12-18 months

The market has responded with premiums for anything that shortens the path: powered shells, build-to-suit on pre-permitted estates, and prefabricated modular capacity. For the full development playbook — siting, tiers, procurement, incentives — see our guide to building a data center.

Cost per MW vs. cost per square foot

Older literature prices data centers per square foot ($600-1,100/sq ft for shell through fit-out in the US). Density has made this metric unreliable: at 10 kW/rack a megawatt needs ~10,000 sq ft of white space; at 100 kW/rack it needs ~1,000. Per-MW is the only comparable unit across designs in 2026, which is why every major cost index (Turner & Townsend, Cushman & Wakefield, CBRE) publishes in $/MW or $/watt.

What moves the number

Density and cooling type. Air-cooled cloud at ~$10-11M/MW; hybrid liquid-cooled AI at $15-20M+. Direct-to-chip retrofit adds $1-3M/MW to an existing hall.
Redundancy tier. Tier II to Tier III adds roughly 15-25% (concurrent maintainability doubles distribution paths); Tier IV adds 30-50% over Tier III.
Market labor and logistics. APAC ex-Japan is cheaper on labor but pays freight and duties on imported MEP; that is why Vietnam ($5.7-8.7M) undercuts Japan ($13M+) by nearly half.
Scale. Multi-building campuses amortize substations and site works; per-MW cost typically falls 10-20% from building one to building three.
Schedule compression. Accelerated programs pay overtime and premium freight; developers report 5-15% premiums for 12-month delivery targets.

Five ways developers cut cost per MW

Buy powered land, even at a premium. Paying 3-5x raw-land price for secured interconnection is usually cheaper than carrying a $300M+ project through an extra 18 months of queue — at a 7% cost of capital, a year of delay on a $340M program is ~$24M before any revenue effect.
Standardize and repeat. Multi-building campuses on a repeated reference design amortize substations, site works, and engineering; per-MW costs typically fall 10-20% between the first and third building. Hyperscalers’ cost advantage is mostly repetition, not procurement muscle.
Prefabricate MEP. Factory-built power skids and cooling modules cut on-site labor (the most inflationary input, per Turner & Townsend) and compress schedules by months — increasingly the default for SEA builds importing equipment anyway.
Source electrical equipment regionally. For Southeast Asian projects, qualified Chinese and regional switchgear, transformers, and busway can run 20-40% below Western-brand pricing. The constraint is tenant approved-vendor lists — resolve specifications before design freeze, not at submittal.
Design the tax position early. Thailand’s BOI exemptions (5-8 years of corporate income tax, capped at 100% of investment value) and similar regimes in Malaysia and Vietnam materially change project NPV, but qualification criteria — PUE thresholds, local-content plans — must be engineered in, not bolted on.

Bottom line

Budget $10-13M per MW in the US, $8-12M in core Southeast Asia, and $6-9M in Vietnam for a conventional Tier III facility in 2026 — plus 20-50% for AI-ready density, plus the IT load itself. Assume 24-48 months end to end, with grid connection as the controlling constraint. Compare against leasing: at $196/kW/month wholesale (current index), a tenant pays ~$2.35M per MW per year — a build-vs-buy equation we track continuously in stats.
