A method for managing heat energy in a metal casting plant includes executing a local control optimization model to control mass of solid metal charges to each modular melting furnace. The local control optimization model is configured to achieve a commanded total mass of molten material and coincidentally minimize waste heat for each of the modular melting furnaces. The method for managing heat energy in the metal casting plant further includes executing a system control optimization model to manage operation of a heat energy recovery system. The system control optimization model is configured to manage the operation of the heat energy recovery system including transferring the waste heat from the modular melting furnaces to a plurality of heat demand centers while minimizing total loss of the waste heat in the metal casting plant.
