Load Reduction Based on Percentage Change in Energy Price

A thermostatic controller comprising:

• a transceiver configured to receive a signal that includes an energy price rate for a given time period;
• an electronic memory device in which one or more energy price rates received by the transceiver are stored;
• and
• a microprocessor in communication with the transceiver and electronic memory, the microprocessor configured to:
• select from the one or more energy price rates the lowest energy price rate received within a given time period for establishing a base energy price rate;
• determine if the energy price rate for a present time period exceeds the base energy price rate by more than a first percentage or multiplier factor of the base energy price rate;
• and
• respond to an energy price rate that exceeds the base energy price rate by more than the first percentage or multiplier factor by transmitting a signal via the transceiver to an energy consuming appliance indicating that the energy consuming appliance should be in an off state and/or to one or more ceiling fans to activate, deactivate and/or change speed of the one or more ceiling fans.
