Generator hire: build a useful load schedule

List what needs power, when it runs and what happens if supply stops. Let the supplier and electrical specialist size the system from that brief.

By Plant Hire Directory · Editorial approach

List actual equipment

Record equipment names, nameplate information and whether items run together or at different times. Include starting loads where known and identify anything that must remain on continuously. Supply photographs of plates if you are unsure how to interpret them. Ask the generator supplier and appropriately qualified electrical person to establish the required system; adding headline wattages is not a complete sizing exercise.

Describe the distribution

Show the proposed generator position and the locations requiring power. Explain cable routes, vehicle crossings and the distance to site facilities. Ask who supplies distribution equipment, cables and any required connection work. Clarify what is included in the hire package so the generator does not arrive without the equipment or authorised people needed to make the system usable.

Plan fuel and attendance

Tell the supplier the expected operating hours and access windows for servicing or refuelling. Ask for fuel-use assumptions for the proposed duty, tank arrangements and monitoring options. Identify who checks the system and who receives an alert or reports a fault. For overnight operation, discuss site security, noise constraints and how support staff can gain access if needed.

Decide what an interruption means

Explain which activities can pause and which require a continuity plan. Ask the supplier to price any backup arrangement separately with its actual changeover scope. Compare delivery, fuel service, distribution and support alongside the base machine rate. At return, retain hour and fuel records and agree who disconnects and collects each part of the package.

Put it into a practical brief

For a temporary site compound, list the individual facilities and equipment rather than asking for a generator for a certain number of workers. Identify which loads start together, which continue overnight and which are essential to the next shift. Send the list to the supplier and electrical specialist for assessment. Ask for the proposed generator, distribution and fuel-service scope to be shown separately. If the compound expands, revisit the load schedule before adding equipment; the original hire package was assessed against the earlier duty, not every future addition.

Putting this guide to work

What should I prepare before contacting suppliers?

Load list and duty supplied. Distribution responsibility assigned. Fuel access arranged. Fault contact nominated. Continuity needs explained.

Does this guide confirm availability or site suitability?

No. Use it to prepare an enquiry. Ask the supplier to confirm the specific machine, current availability and written terms, and have the responsible site team assess suitability.
