A load control management protocol, system, and method that address many different customers, individually, in geographic groups, or in other predefined groups to control at least one or more electrical power consuming appliances are disclosed. The computer-implemented protocol provides wired and wireless communication schemes that enable a utility to quickly and efficiently communicate commands and messages to end user devices. Specific electrically powered appliances and certain uses of electricity can therefore be managed by communicating with the controllers of those appliances, providing management of a utility load during peak price and consumption periods to prevent delivery interruptions.
