Abstract: This disclosure presents processes for controlling a hydraulic fracturing operation at a wellbore. The processes can determine power available from each of one or more individual power sources. From the determined power available from the power sources, parasitic power losses, existing power consumed by one or more loads of the hydraulic fracturing operation, a threshold power level, or a combination thereof, the processes can determine an incremental power available to the one or more loads. The processes communicate the incremental power available to the one or more loads. The hydraulic fracturing operation is then controlled by processes based on the incremental power available to the one or more loads.
