Find Capacity · Wholesale & Build-to-Suit
Wholesale data centre colocation, sourced to your power and delivery date.
For AI, cloud and enterprise compute buyers, multi-megawatt wholesale colocation often pre-lets before public marketing. We screen live and upcoming wholesale data centre capacity against your MW, density and delivery date, compare operator proposals side by side, and introduce you directly. 115 facility and 44 operator profiles tracked in AU and the UK.
Why sourcing wholesale colocation takes more than a directory
Contiguous multi-megawatt capacity in primary metros is scarce, and new data halls regularly pre-let during construction before they appear on public listing portals.
Operators commonly treat commitments of one megawatt or more as clearly wholesale (Data Center Scouts), with typical wholesale lease terms running from five to 20 years (CBRE Investment Management). At that scale and tenure, picking the wrong hall or build-to-suit schedule locks in years of stranded power, cooling bottlenecks, or delayed energisation.
Approaching operators one by one telegraphs your deployment roadmap to the market while leaving off-market expansion phases, powered shells, and pre-let opportunities unseen.

Buyer’s guide: wholesale capacity models, retail comparisons and diligence
Wholesale capacity models and thresholds
Wholesale data centres provide dedicated whitespace and power infrastructure between shared retail colocation and bespoke build-to-suit developments. Commitments of one megawatt or more are generally treated as wholesale, though private suites may exist below this scale. Typical wholesale lease terms run from five to 20 years, requiring careful review of renewal rights, early surrender terms and reinstatement duties.
Turnkey wholesale:
The operator supplies fitted whitespace with operational plant. Occupiers supply IT equipment and confirm whether containment and structured cabling are included or billed separately.Powered shell:
The landlord provides the building envelope and utility connection. The occupier funds and fits out internal mechanical and electrical plant and whitespace.Powered land verification:
The phrase “powered land” is an industry marketing term, not a certification. Sellers use it for anything from an initial utility enquiry to an executed connection agreement. Buyers should ask landowners whether the network operator has issued a binding connection agreement, what queue position and written energisation date the utility has confirmed, whether connection deposits are paid, and whether off-site cable easements to the substation are secured.
Comparing wholesale and retail colocation
Retail colocation provides space by the cabinet or cage in shared whitespace with communal plant and security, whereas wholesale colocation delivers dedicated suites or entire halls. Buyers should compare offers across four boundaries:
- Physical demarcation: Dedicated slab-to-slab hall without shared air plenums versus shared whitespace.
- Power billing: Metered utility pass-through with an agreed PUE formula, fixed reservation charge, or bundled rack rate, plus any utility management mark-ups.
- Environmental control: Individually adjustable rack intake temperature and humidity set-points versus shared facility bands, and support for direct liquid cooling or non-standard containment.
- Telecommunications: Private duct entries and dedicated pathways versus shared meet-me rooms, and whether carrier cross-connects are billed as one-off installations or recurring monthly charges.
Build-to-suit evaluation
Build-to-suit developments apply when multi-tenant halls cannot satisfy scale, engineering, location, or asset-control requirements:
- Scale requirements: Power demand exceeds contiguous space in operational campuses, requiring dedicated substations.
- Bespoke engineering: Non-standard floor loading, higher ceilings, or specialised cooling topologies cannot be retrofitted.
- Strategic location: Sites require proximity to private generation, industrial facilities, or subsea landing stations.
- Asset control: Occupiers require long-term ground leases, purchase options, or freehold ownership.
Turnkey wholesale is faster where suitable capacity and utility power already exist on site. Greenfield projects require planning approvals, grid connections, civil construction, and integrated testing before IT fit-out. Buyers should ask developers what planning and environmental approvals remain, whether a signed connection agreement confirms energisation dates, who carries financial liability for grid delays or civil cost overruns, and whether early access is permitted for IT fit-out before practical completion.
Commercial leases and demarcation boundaries
Wholesale leases allocate maintenance and utility costs across two primary structures:
- Modified gross: The landlord maintains the building shell and primary plant, while the tenant pays base rent plus metered power.
- Triple net: The tenant pays base rent and manages or reimburses taxes, insurance, and plant maintenance directly.
Occupiers should verify demarcation boundaries on electrical single-line diagrams (utility switchgear, transformer terminals, UPS outputs, or busway tap-offs) and mechanical schematics (central chilled water risers, CRAH valves, or rack distribution), plus external cable pathway maintenance, advance notice for upstream maintenance, SLA credits for power or thermal breaches, contracted baseline PUE, sub-metering records, and make-good obligations at lease expiry.
Technical due diligence questions
Engineering review across critical building systems should verify:
- Are critical electrical and mechanical distribution paths concurrently maintainable without dropping resilience?
- How many hours of generator fuel are stored on site at full load, and what is the testing schedule?
- Does cooling continue uninterrupted during the transfer from grid to backup generators?
- What are the certified maximum static and dynamic floor loading limits across whitespace and delivery routes?
- What fire suppression and water-leak detection systems protect the whitespace?
- What historical flood, seismic, and adjacent industrial risks apply to the site?
Wholesale data centre colocation FAQs
What scale distinguishes wholesale colocation from retail colocation?
Wholesale thresholds vary across operators and facility designs. Commitments of one megawatt or more are commonly treated as wholesale, though private suites can be available below that threshold. Occupiers should ask providers what minimum power commitment is required for dedicated whitespace.
What lease duration applies to wholesale data centres?
Wholesale data centre leases typically run from five to 20 years, providing long-term tenure alongside structured renewal options. Occupiers should examine renewal rights, early surrender terms, and reinstatement duties before signing.
What capital outlay distinguishes turnkey wholesale from build-to-suit?
In turnkey wholesale, the operator finances and installs the power, cooling, and building infrastructure. Occupiers primarily fund their IT equipment, and should verify whether containment screens, security cages, and structured cabling are included in base charges. In build-to-suit models, the occupier may fund or amortise some or all of the site purchase, building shell, utility connection, and dedicated plant depending on the contract.
How is power billed in wholesale colocation contracts?
Wholesale contracts typically bill electricity as a metered pass-through based on utility tariffs, adjusted by an agreed PUE formula, alongside a fixed reservation charge per kW or MW. Other contracts apply fixed power charges or utility mark-ups. Occupiers should ask providers directly about billing formulas, sub-meter locations, and tariff pass-through terms.
What does the industry term powered land mean?
The phrase "powered land" is an industry marketing term rather than a formal certification. Sellers use it to describe land parcels with varying stages of grid engagement, from initial enquiries to executed connection agreements. Prospective buyers should verify signed connection agreements, queue position, paid deposits, and confirmed energisation dates directly with the network operator.
How much does a 200 MW data centre cost?
Total capital cost for a 200 MW wholesale or hyperscale data centre campus depends on electrical redundancy, liquid cooling infrastructure, substation works, and regional construction rates. See our cost to build a data centre guide for current, sourced per-MW benchmarks. Wholesale colocation allows occupiers to secure multi-megawatt capacity without funding the upfront base-build capital expenditure.
Is it profitable to own a data centre?
Data centre ownership can deliver durable infrastructure returns when backed by creditworthy wholesale or hyperscale tenants on five- to 20-year leases. Profitability depends on securing firm utility power, controlling construction and financing costs, and maintaining high capacity utilisation.
