A method for heat coordination is provided. The method includes operating a propulsion system that generates heat as wasted power, operating a device utilizing the heat generated by the propulsion system, and operating a heat transfer system configured for transferring the heat generated by the propulsion system from the propulsion system to the device. The method further includes, within a computerized processor, determining a minimum useful waste thermal power to operate the device, monitoring a desired output torque for the propulsion system, and utilizing a cost-based determination to determine a propulsion system operating point based upon the desired output torque and the minimum useful waste thermal power to operate the device. The method further includes utilizing the propulsion system operating point to control the propulsion system.
