Method of load shedding to reduce the total power consumption of a load control system

A lighting control system is operable to control the amount of power delivered to a plurality of electrical loads. The lighting control system includes load control devices (such as digital electronic dimming ballasts), motorized window treatments, controllers, processors, and personal computers. The personal computer is preferably executing a graphical user interface (GUI) software, which allows a user to configure and monitor the operation of the lighting control system. The lighting control system offers a load shedding functionality without using power meters. Each load control device transmits its current intensity level to the personal computer, which is operable to determine a total power consumption of the lighting control system. If the total power consumption exceeds a predetermined power threshold, the personal computer causes the load control devices to shed loads.
