RATINGS DEFINITIONS
The power ratings of Emergency Standby and Prime are in accordance with ISO 8528. Fuel Stop power in
accordance with ISO 3046.
Electric power (kW) should be estimated by considering generator efficiency, cooling fan power loss and power
derating due to altitude and ambient temperature.
STANDBY POWER RATING is applicable for supplying emergency power for the duration of the utility power
outage. No overload capability is available for this rating. A standby rated engine should be sized for a maximum
of a 70% average load factor and 200 hours of operation per year. This includes less than 25 hours per year at the
Standby Power rating.
PRIME POWER RATING is available for an unlimited of hours per year in variable load application. Variable load
should not exceed a 70% average of the Prime Power rating during any operating period of 24 hours. The Total
operating time at 100% Prime Power shall not exceed 500 hours per year. A 10% overload capability is available
for a period of 1 hour within a 12 hours period of operation. Total operating time at the 10% overload power shall
not exceed 25 hours per year.
CONTINUOUS POWER RATING is the power that the engine can continue to use under the prescribed speed and
the specified environment condition in the normal maintenance period stipulated in the manufacturing plant. And
continuous power applicable for supplying utility power at a constant 100% load for an unlimited number of hours per
year. No overload capability is available for this rating.
