Data Centre Technical Due Diligence: What Investors Should Test Before Capital Is Committed
Testing the investment case, not confirming that documents exist.

Technical due diligence is not a checklist confirming that drawings, equipment and permits exist. Its purpose is to test whether the asset, site and delivery plan can support the investment case at the required capacity, resilience, programme, cost and operational standard. A technically feasible project can still be a poor investment when critical dependencies remain unproven.
Strong capital appetite raises the standard of evidence.

Reports that power availability and connection timing now lead site selection constraints in major markets.

Feasibility is not the test. Evidence is.
A campus valued on four phases and consented for two is a different asset from the one being purchased.
If no single party owns an interface, the investor owns it.
Every critical assumption sits in one of four states.
A number in a model carries no record of how it was established. The first task of diligence is to place each critical assumption and to name what would move it forward.
Stated
Asserted in a document, presentation or model. No instrument behind it.
Contracted
Secured by an agreement with a counterparty, a date and a consequence.
Deliverable
Achievable within the programme, supply chain and consents actually held.
Proven
Demonstrated by test, energisation or operation under design conditions.
Confidence should follow the state of the evidence, not the confidence of the presentation.
The intended design and the installed reality are two different sources of evidence.

Test the case, not the file
Confirming that drawings, consents and equipment schedules exist proves completeness of a data room. It does not prove that the asset can support the investment case at the required capacity, resilience, programme, cost and operational standard.
Separate the stated from the proven
A capacity figure can come from a firm connection agreement, a reserved allocation, a non-binding indication or an estimate. All four appear in a model as the same megawatts. The paper sets out how to categorise each critical assumption and what would move it.
Follow the dependency to its owner
Where an outcome depends on works outside the developer's control, that dependency belongs in the investment case with a date, an owner and a consequence if it slips. Risk that sits between organisations usually returns to the investor.
