A method and system may be provided to perform a process for controlling power provided by an engine in a machine. In an embodiment of the present invention, a process for controlling power provided by an engine operating in a machine is provided. The process may include determining a first power value reflecting a predetermined first power to be provided by the engine to a component operating in the machine. Further, the process may include determining, during machine operations, at least one of a parasitic power value reflecting power received by a parasitic load module from the engine and an intermittent power value reflecting power received by an intermittent load module from the engine. A second power value may then be determined that reflects a second power provided by the engine based on the parasitic power value, the intermittent power value, and the net power value. Based on changes in at least one of the parasitic power value and the intermittent power value, the process may adjust the second power value such that the engine substantially provides the predetermined net power to the component.
