Benefits of technology
The system reduces peak energy demand, lowers utility bills, and provides customers with granular control over energy usage, preventing brownouts while maintaining appliance functionality and safety, all at a low cost.
Problems solved by technology
Currently utilities charge a flat rate, but with increasing cost of fuel prices and high energy usage at certain parts of the day, utilities have to buy more energy to supply customers during peak demand.
However, there is no active control beyond the mere on / off switching.
One difficulty is that no peak shaving method for an appliance such as a refrigerator will provide a maximal benefit.
Similarly, known systems do not communicate directly with the appliance using a variety of communication methods and protocols, nor is a modular and standard method created for communication devices to interface and to communicate operational modes to the main controller of the appliance.

Embodiment Construction
[0031]In one embodiment, a more advanced system is provided to handle energy management between the utility and the homeowner's appliances. The system can include one or more of the following: a controller, utility meter, communication network, intelligent appliances, local storage, local generator and / or demand server. Less advanced systems may actually allow the appliance to “communicate directly with the utility meter or mesh network through the DSSM (Demand Side Management Module) (FIG. 1). The demand server is a computer system that notifies the controller when the utility is in peak demand and what is the utility's current demand limit. A utility meter can also provide the controller the occurrence of peak demand and demand limit. The demand limit can also be set by the home owner. Additionally, the homeowner can choose to force various modes in the appliance control based on the rate the utility is charging at different times of the day. The controller will look at the energy...

A cooking appliance comprises one or more power consuming features / functions including at least one of a cooking cavity having a heating element and a cooking surface having a surface heating element. A controller is configured to receive and process a signal indicative of current state of an associated energy supplying utility. The controller operates the cooking appliance in one of a plurality of operating modes, including at least a normal operating mode and an energy savings mode, in response to the received signal. The controller is configured to at least one of selectively delay, adjust and disable at least one of the one or more power consuming features / functions to reduce power consumption of the cooking appliance in the energy savings mode.
