Abstract: A utility consumption optimization mechanism may determine an optimized period for consuming a utility based on several input parameters and several constraints. The optimization mechanism may determine an optimum consumption time and cause a device to consume the utility during that time. A schema may define various parameters that may be passed to a rate calculation mechanism, and the optimization mechanism may use the rate calculation mechanism to find an optimized consumption schedule for a particular application. The optimization mechanism may be implemented as an embedded controller in a consuming device, as a web service that may be available through an Internet connection, or in other embodiments.
