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 Demand
Convert container count, running power and duty cycle into average kW and total MWh
Fuel + Shore Power
Split electrical demand between onboard generation and shore electricity
Capacity Screen
Advanced mode compares diversified peak demand with 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.
