Capacity & Offtake · For developers, landowners and sponsors

Anchor tenants and pre-lets for your data centre.

An anchor tenant is the lead customer whose multi-megawatt commitment underpins a new data centre development. A pre-let (UK and Australia) or pre-lease (US) is a binding agreement to lease a data center hall or campus before construction completes. Customer offtake is a contracted IT load commitment, distinct from a power offtake agreement for electricity supply.

Commercial impact

What an anchor tenant changes for your project

Securing a foundational customer commitment transforms how lenders, investors and utilities treat a development scheme:

  • Development and construction finance:

    Infrastructure lenders and debt funds underwrite project finance and forward funding against contracted cashflows and tenant covenant strength. A signed pre-let or customer offtake agreement moves a site from speculative development to a bankable asset.
  • Joint ventures and equity partnerships:

    Institutional co-investors and development JV partners price powered land and consented schemes on a different basis once an anchor tenant has committed to phase-one IT load. Explore Capital & Partnerships.
  • Engineering and phasing certainty:

    Locking in an anchor customer before breaking ground allows you to engineer substation phasing, rack density and liquid-cooling plant around a committed technical specification rather than building speculative M&E infrastructure.

Buyer requirements

What a customer needs to see before it commits

Capacity buyers committing to an unbuilt facility weigh delivery certainty alongside technical design. Before entering heads of terms on a pre-let, an anchor customer will look for clear evidence across these areas:

  • MW by phase:

    Initial IT load available at phase-one handover, plus the expansion ramp across subsequent data halls or buildings.
  • Power basis and energisation date:

    Confirmed grid import capacity, utility connection offer status, substation works programme and firm energisation milestones.
  • Density and cooling:

    Supported kW per rack, floor loading, and whether the plant is designed for air cooling, chilled water or direct-to-chip liquid cooling.
  • Location and latency:

    Proximity to metro availability zones, internet exchanges or high-capacity transmission routes, alongside planning permission and zoning status.
  • Fibre:

    Diverse dark-fibre routes, carrier neutrality, meet-me room architecture and point-of-entry redundancy.
  • Delivery date:

    Credible programme dates for shell completion, M&E commissioning, integrated systems testing and ready-for-service handover.
  • Structure:

    Whether the scheme is offered as a turnkey wholesale lease, a powered shell lease where the tenant completes M&E fit-out, or a build-to-suit campus.

Demand side

Customers we introduce

We connect data centre developments and powered sites across Australia, the UK, the US and Canada with four groups of capacity buyers:

  • AI and cloud clients: Hyperscale cloud platforms and AI infrastructure buyers acquiring contiguous multi-megawatt halls or dedicated campuses with firm power delivery dates.
  • Neoclouds: Specialist GPU cloud operators scaling high-density liquid-cooled clusters who require committed MW on rapid delivery schedules.
  • Enterprise buyers: Financial institutions, digital platforms, research organisations and corporate infrastructure teams consolidating regional workloads into long-term wholesale space.
  • Operators pre-letting: Established colocation and wholesale operators taking powered shells or build-to-suit facilities to serve their own customer demand.

Transaction terms

Anchor tenant, pre-let and offtake: how they differ

While the three terms often appear together in development funding discussions, each describes a distinct part of the deal:

  • Anchor tenant: The lead customer whose commitment justifies building a new facility or campus phase. An anchor typically contracts a major share of phase-one IT load or a whole building on a long-term lease, establishing the credit profile for the asset.
  • Pre-let (UK and Australia) or pre-lease (US): The legal and timing structure of the commitment. The customer signs a binding lease or agreement for lease ahead of practical completion, with rent commencement tied to ready-for-service delivery milestones.
  • Customer offtake: A long-term contract to take and pay for a defined volume of data centre capacity, measured in MW of IT load, used by sponsors and lenders to underwrite project debt. It is separate from a power offtake agreement or power purchase agreement (PPA), where an energy generator sells electricity to a buyer.

From site to heads of terms

How a commitment is staged

  • Stage one:

    Project profile: You share your site location, power allocation, energisation schedule, planning status and preferred lease structure.
  • Stage two:

    Customer matching and introduction: We match your project’s MW scale, delivery window and cooling design against customer requirements in our network and introduce you directly to relevant buyers.
  • Stage three:

    Technical due diligence and heads of terms: You and the prospective customer take the conversation forward to review grid connection documentation, campus layouts and delivery programmes, progressing to heads of terms and an agreement for lease.

FAQ

Questions owners ask

What is considered an anchor tenant in a data centre?

An anchor tenant is the foundational customer taking the first major tranche of capacity in a new data centre or campus development. Their multi-megawatt commitment and credit covenant typically unlock construction debt, forward funding or joint venture capital for the developer.

Who are the tenants of data centres?

Data centre tenants fall into four main groups: hyperscale cloud and AI platforms, GPU cloud providers (neoclouds), enterprise and public-sector organisations running private IT infrastructure, and colocation operators leasing powered shells to serve their own customers.

Who are the largest data centre tenants?

The largest capacity takers globally are hyperscale cloud service providers, consumer internet platforms and frontier AI companies, which lease whole buildings or multi-building campuses in multi-megawatt blocks, alongside global banks and telecommunications carriers.

How much do data centres pay for rent?

Data centre rent is priced on a per-kilowatt-per-month basis for turnkey wholesale capacity, or per square metre or square foot for powered shell leases, with electricity billed separately. For rate benchmarks and pricing drivers, see our guide to data centre leasing.

How do data centre leases work?

Large capacity commitments are structured as turnkey wholesale leases, where the developer delivers fitted M&E plant, or powered shell leases, where the landlord delivers the building envelope and grid power and the tenant funds fit-out.
