Reefer Container Power & Fuel Cost Calculator
Estimate reefer container electrical demand, total energy consumption, auxiliary-generator fuel use, shore-power cost, generator maintenance, carbon cost and cost per reefer-day. Advanced mode separates chilled, frozen and special-cargo reefers while adding electrical losses, energy-management savings, peak-demand diversity and available reefer-power capacity.

Reefer Power & Fuel Cost Results
Simple reefer electrical-cost estimate
Enter reefer data
Enter reefer count, running power, duty cycle and analysis
period to calculate electrical demand, generator fuel use
and reefer power cost.
Planning estimate only.
Actual reefer power consumption can vary substantially with cargo
setpoint, ambient temperature, humidity, container insulation,
machinery condition, compressor operation, defrost cycles,
ventilation settings, controlled-atmosphere equipment, door-open
history, precooling, plug interruptions, vessel routing, terminal
conditions and power-management strategy. Running-kW and duty-cycle
inputs should come from vessel, terminal, OEM or monitoring data when
available. This calculator does not assess cargo-temperature risk,
electrical protection, plug compatibility or vessel stability.
