Generator Fuel Consumption Calculator Excel

This generator fuel consumption calculator helps you determine how much fuel your generator will use based on its power output, runtime, and fuel efficiency. The calculator provides results in gallons, liters, or other common fuel measurement units, and can generate a consumption chart for better visualization.

How to Use This Calculator

To calculate generator fuel consumption:

Enter the generator's power output in kilowatts (kW).
Specify the runtime in hours.
Select the fuel type (diesel, gasoline, propane, etc.).
Enter the fuel efficiency in kWh per gallon or liter.
Click "Calculate" to get the fuel consumption.

The calculator will display the total fuel consumption and provide a breakdown of the calculation. You can also export the results to Excel for further analysis.

Formula Explained

The fuel consumption is calculated using the following formula:

Fuel Consumption = (Power Output × Runtime) ÷ Fuel Efficiency

Where:

Power Output is the generator's power in kilowatts (kW).
Runtime is the total operating time in hours.
Fuel Efficiency is the energy output per unit of fuel (kWh per gallon or liter).

For example, a 10 kW generator running for 8 hours with a fuel efficiency of 0.5 kWh per gallon would consume:

(10 kW × 8 hours) ÷ 0.5 kWh/gallon = 160 gallons

Worked Example

Let's calculate the fuel consumption for a 15 kW diesel generator running for 6 hours with a fuel efficiency of 0.4 kWh per liter.

Fuel Consumption = (15 kW × 6 hours) ÷ 0.4 kWh/liter = 225 liters

This means the generator will consume 225 liters of diesel fuel during the 6-hour runtime.

Excel Compatibility

You can use this calculator's results in Excel by copying the formula into a cell:

= (Power Output × Runtime) ÷ Fuel Efficiency

For example, in cell B2, you could enter:

= (A2 × B1) ÷ C1

Where A2 is the power output, B1 is the runtime, and C1 is the fuel efficiency.
