UPS & Critical Power Design & Deployment | Australia
End-to-end critical power design: sizing, redundancy, switchgear, generator integration and project delivery.
UPS Services delivers end-to-end critical power design and deployment for new-build and brownfield Australian sites. Our scope spans single-line drawings, sizing calculations, switchgear specification, generator integration, ATS/STS control logic, battery system design, and project delivery through to commissioning.
We work alongside client mechanical engineers, IT teams, project managers and main contractors to deliver power architectures that meet uptime targets (Tier I-IV), capital budget and growth plans. Designs are documented to AS/NZS 3000 with full schematic, panel schedules, protection coordination and load-flow analysis.
Project delivery includes equipment procurement, factory acceptance testing (FAT), site acceptance testing (SAT), as-built drawings, and operator training, a single-vendor contract for the critical power scope.

Frequently asked questions
3 questions answered.
Q01
What is the difference between Tier I, II, III and IV?
Tier classifications (per Uptime Institute) define redundancy and concurrent maintainability: Tier I = single path, no redundancy (~99.671% availability); Tier II = redundant components (99.741%); Tier III = concurrently maintainable, multiple paths but only one active (99.982%); Tier IV = fault-tolerant, fully dual-bus (99.995%). Higher tiers add CapEx significantly, and we help clients size to actual business risk rather than aspirational targets.
Q02
Do you handle generator integration?
Yes. We design the full critical power chain: UPS, battery, ATS (Automatic Transfer Switch), generator, switchgear, and specify the controls logic that coordinates utility-loss detection, generator start, transfer timing, and return-to-utility sequencing. We work with most major generator brands (Cummins, Caterpillar, MTU, FG Wilson, Kohler).
Q03
How long does a typical critical power design take?
Concept design + sizing for a small comms room: 2-3 weeks. Tier III data centre detailed design: 8-16 weeks depending on integration complexity. We can provide concept-level designs as part of pre-tender support, and full detailed design under a separate professional services engagement.
