Define the measurement boundary
Utility service describes an electrical supply boundary. Critical IT describes the power available to the IT equipment under a stated design and resilience basis. Campus potential can describe an aspiration across future phases. These figures should not share a comparison column without a basis label.
Use PUE carefully
For a screening scenario, a 40 MW IT load at an assumed PUE of 1.25 implies 50 MW of facility demand at that operating point. The calculation does not confirm contractual service, peak design load, redundancy or a usable commissioning date. Treat PUE as an explicit assumption until suitable project evidence supports it.
Ask for the phase schedule
Request the load available in each phase and the conditions governing each step. A future total should not be substituted for phase-one availability. Record whether a figure is cumulative or incremental, and confirm whether the date refers to energisation, commissioning or customer operation.
Take this checklist into the next meeting
- Label the original capacity basis.
- Record explicit conversion assumptions.
- Distinguish cumulative from incremental phases.
- Keep capacity and availability dates together.
Evidence and assumptions
This guide develops the supplied buyer-side research framework. It makes no site-specific capacity claim. Obtain current utility documents, manufacturer specifications and appointed professional advice for the actual project. Any numerical examples are worked examples, not project data.
