<p>A washing machine (400) and a method of controlling the same include a motor (412) to rotate a rotary tub (411) including laundry, a heater (430) to heat water contained in the rotary tub (411), a communication unit (441) to receive an energy saving signal having information regarding an energy saving start time from an energy management system (EMS) (300), and a controller (442), upon receiving the energy saving signal, to determine which one of the motor (412) and the heater (430) is a load having highest power consumption in a process to be executed at the energy saving start time, and reduce the operation rate of the determined load. Before current power rates exceed reference power rates, the load operation rate of the washing machine (400) is changed so that power consumption is greatly reduced.</p> |
