Power Generation Hire in Western Australia is shaped by distance from fuel, heat derating and remote-site servicing. Western Australia's plant hire market is shaped by distance and resources. Brief suppliers on the outcome, access and ground, and confirm where the machine will travel from.
Local conditions in Western Australia
Perth sits on the Swan Coastal Plain's deep sands—easy digging but unstable trench walls and demanding compaction. Inland and in the Pilbara, hard rock and caprock call for breakers and ripping.
Mediterranean in Perth and the South West; hot desert across the interior; tropical with cyclones in the Pilbara and Kimberley.
Cyclone season in the north runs November to April; summer heat across the interior affects machine cooling, operator fatigue and night-shift planning.
WA is not part of the national heavy vehicle scheme. Oversize and overmass permits are issued by Main Roads WA Heavy Vehicle Services.
Major demand for generators in Western Australia comes from mining, oil and gas, infrastructure, agriculture, residential construction. Metropolitan depots around Perth generally carry the widest fleet; regional jobs should confirm mobilisation distance, transport charges and field-service support before comparing rates.
Motors, welders, compressors and pumps draw several times their running current on start-up, so a generator sized only to running load can trip or stall. Suppliers normally size in kVA and allow headroom for starting loads and future additions.
Remote and long-duration hires need a refuelling plan, bunded fuel storage and a service schedule. Lighting towers, cable, distribution boards and RCD protection are often part of the same package.
Power classes and sizes
The table below lists the classes of generators most commonly available for hire in Western Australia. Exact specifications vary by make and model—confirm dimensions, weight and capacity with the supplier before booking.
| Class | Size / spec | Typical jobs |
|---|---|---|
| Portable generator | 2–8 kVA | Hand tools, small sites, trades |
| Towable generator | 20–150 kVA | Site sheds, pumps, cranes, events |
| Large / containerised | 200–1,000 kVA + | Shutdowns, mines, backup for buildings |
| Lighting tower | 4 × LED · 9 m mast | Night works, roads, security |
| Distribution / cable | Boards, RCDs, leads | Safe temporary power distribution |
How to choose the right machine
List every load
Record the running kW and phase of each item and identify motors with high starting current. Share the list with the supplier.
Plan fuel
Ask about fuel consumption at expected load, tank run time, bunding and who refuels.
Consider noise
Residential, hospital and event sites may need super-silenced sets or specific placement.
Get it connected properly
Connection to fixed installations must be done by a licensed electrician with correct changeover and earthing.
Licences, tickets and compliance
- Temporary electrical installations on construction sites must meet AS/NZS 3012, including RCD protection and regular testing and tagging.
- Connection to a building's switchboard requires a licensed electrician and correct changeover arrangements.
- Fuel storage requires bunding appropriate to volume and environmental conditions.
See our plant licences and tickets guide for the full list of High Risk Work Licence classes.
What drives the cost
The hire rate is only part of the total. On short hires these items often add 20–50% to the bill—ask every supplier to quote them the same way:
- Unit size and run time
- Fuel and refuelling service
- Cabling, boards and electrician connection
- Transport and crane off-load for large sets
- Standby and backup units for critical loads
