Approximate Fuel Consumption Chart
This chart approximates the fuel consumption of a diesel generator based on the size of the generator and the load at which the generator is operating at. Please note that this table is intended to be used as an estimate of how much fuel a generator uses during operation and is not an exact representation due to various factors that can increase or decrease the amount of fuel consumed.
NOTE : 1 US gal = 3.79 liters
1 UK gal = 4.57 liters
|Generator Size (kW)||1/4 Load (gal/hr)||1/2 Load (gal/hr)||3/4 Load (gal/hr)||Full Load (gal/hr)|
Generator Set Ratings
Emergency Standby Power (ESP)
Output available with varying load for the duration of an emergency outage. Average power output is 70% of the ESP rating. Typical operation is 50 hours per year, with maximum expected usage of 200 hours per year.
Standby Power Rating
Output available with varying load for the duration of an emergency outage. Average power output is 70% of the standby power rating. Typical operation is 200 hours per year, with maximum expected usage of 500 hours per year.
Prime Power Rating
Output available with varying load for an unlimited time. Average power output is 70% of the prime power rating. Typical peak demand is 100% of prime rated kW with 10% overload capability for emergency use for a maximum of 1 hour in 12. Overload operation cannot exceed 25 hours per year.
Continuous (or Baseload) Power Rating
Output available with non-varying load for an unlimited time. Average power output is 70-100% of the continuous power rating. Typical peak demand is 100% of continuous rated kW for 100% of operating hours.
