A ballast load control system and method is presented that regulates the output electrical power supplied by a turbo-generator such that appropriate turbine loading may be achieved. Such enables the use of a turbo-generator having an expansion turbine to be used to provide a controlled, required amount of cooling to a thermal control system. By effectively varying the coupled electrical load, the loading provided to the expansion turbine may be controlled while maintaining output power requirements to connected electrical utilization equipment. Use of a common system controller for both the cooling system and ballast trim load system of the present invention ensures coordinated operation between the required amount of cooling and electrical power quality supplied to the coupled utilization equipment.
