DEFINITION OF RATED POWER

Rated power is defined as the power available for supplying utility power at a constant 100% load for an unlimited number of hours per year. This rating does not include overload capability.

The listed rated power is based on the following standard conditions:

  • 100 kPa barometric pressure (equivalent to an altitude of 110m)
  • 25°C air inlet temperature
  • 30% relative humidity
  • Natural gas fuel with a methane number of 80 and a lower heating value (LHV) of 36.3 MJ/Nm³.
