Data centres: a power contract is not a grid connection
The commercial gap between buying energy and operating new computing capacity.
Public-source desk research checked 16 October 2026. Company statements are attributed; commercial conclusions are Offaxis analysis. Illustrative scenarios are labeled. We have not independently tested products or audited company accounts.
The investment bottleneck has a location
Our thesis is that data-centre expansion creates several distinct markets: energy supply, grid capacity, electrical equipment, onsite power and operating flexibility. Treating them as one “AI power” opportunity hides who actually purchases each product and when payment can begin.
What the IEA reports
The IEA’s Powering Artificial Intelligence executive summary describes pressure on local networks and electrical-equipment supply chains. It also describes growing procurement through power purchase agreements and emerging arrangements involving storage, onsite generation and other technologies. These are sector observations, not evidence that a particular proposed data centre has secured a connection or an economically viable power supply. [1]
Energy and deliverability are different
A power purchase agreement can address an energy procurement or price requirement. It does not, by itself, demonstrate that the site can receive the required capacity at the required time. Our interpretation is that a project’s commercial schedule needs separate milestones for supply contracting, network access, equipment delivery and commissioning. A headline megawatt figure without a date and service boundary is incomplete.
| Commercial layer | What is supplied | Evidence to examine |
|---|---|---|
| Energy procurement | Purchase or hedge electricity | Contract terms and delivery profile |
| Network connection | Access physical system capacity | Binding milestones and upgrade responsibility |
| Onsite equipment | Deliver usable power infrastructure | Fuel, commissioning, support and retirement plan |
Who might capture the spending?
A generator sells energy or contracted capacity. A network operator addresses regulated connection and system needs. Equipment suppliers deliver transformers, switchgear and other physical infrastructure. A storage or flexibility provider may sell a defined operational service. Each position faces different qualification, delivery and financing requirements. An analyst should identify the purchasing entity and the revenue trigger before assigning a supplier to an attractive growth theme.
The opportunity cost of delay
Consider an illustrative facility ready to serve customers but unable to operate at planned capacity. A more expensive interim power option could make commercial sense if the contribution from earlier operation exceeds its incremental cost and risks. That is a project-specific comparison, not a general endorsement of onsite generation. It requires the actual customer contract, demand ramp, fuel assumptions and replacement plan.
What we would ask next
Identify binding connection dates rather than requests, contracted rather than aspirational load, and the responsibility for equipment delays. Ask how much demand can move in time without breaking customer commitments. The thesis improves when supplier orders can be linked to funded projects and credible energization milestones. It weakens when multiple announcements describe the same future capacity or project economics depend on an uncommitted network upgrade.
