Power Planner

About this app

Power Planner sizes generators and builds complete power plans for events,
construction sites, off-grid camps, and field operations.

Every other tool gives you a flat wattage guess. Power Planner gives you a
real bill of materials: the generator size, the fuel, the leads, the distribution
boxes - and what happens when something fails.

TWO MODES

POWER PLANNER - Have a generator? Add your appliances and instantly see load percentage, surge headroom, and fuel burn. Perfect for camping, caravans, tradies, and home blackout backup.

POWER PLANNER PRO - Need power for an event or site? Add your equipment and get told what to hire or bring:

• Three-tier load model: connected load, realistic demand load (duty cycles),
and design load with a 25% safety buffer
• Generator recommendations from standard commercial sizes (8-1000 kVA),
including dual-unit redundancy options
• Multi-generator planning: assign equipment to zones, balance three-phase
loads, and see per-unit utilisation
• Fuel logistics: burn rates, daily and total litres, jerry cans, drums, and
resupply runs
• Distribution kit: lead counts by plug type (10A / 15A / 32A / hardwired),
distribution boxes, and cable estimates
• Load priority tagging (Critical / Essential / Deferrable) with an automatic
load-shedding plan if a generator fails
• Recommended startup sequence to manage motor surge
• Generator service schedule tracking with hour meters
• Cost estimation and quote builder for hire companies
• CSV equipment import, PDF plan export, shareable plans

Scenario presets get you started fast: events and festivals, construction
sites, accommodation and camps, and more. A Field Ops template pack for government & logistics users is available via access code (see the
About screen).

BUILT FOR THE FIELD

Power Planner works 100% offline. No account, no sign-in, no cloud, no data
collection - your plans stay on your device. Use it in a paddock, a basement,
or anywhere else the job takes you.

IMPORTANT

Power Planner produces planning estimates only. All power configurations must be verified by a qualified licensed electrician before implementation.
