A control system for a machine having an engine, a first alternator, a second alternator, and an aftertreatment system is disclosed. The control system may include a sensor associated with the aftertreatment system and configured to determine a temperature of exhaust passing through the aftertreatment system, and a controller in communication with the sensor and connectable to the first and second alternators. The controller may be configured to determine an available power output of the first alternator, determine a load increase of the engine needed to raise the temperature of the exhaust to an operating temperature of the aftertreatment system, and selectively connect the first alternator to a power consumer to achieve the load increase when the available power output of the first alternator is greater than the load increase. The controller may be further configured to selectively connect the second alternator to the power consumer to achieve the load increase when the available power output of the first alternator is less than the load increase.
