Abstract
A method of reducing electricity usage during peak demand periods includes the steps of establishing predetermined load reduction criteria representative of a desire by a power provider to reduce loading on an electricity supply grid, and coordinating with a facility having lighting equipment to permit the power provider to turn-off one or more of the lighting equipment by sending instructions to a master controller at the facility in response to the predetermined load reduction criteria, and establishing a list of lighting equipment to be turned-off in response to the instructions, and configuring the master controller to send an override control signal to the lighting equipment to implement the instructions, and configuring the lighting equipment to send a response signal to the master controller providing a status of the lighting equipment.
