Abstract

A dynamic electrical power pricing communication system is provided. The system comprises at least one computer system, at least one memory, a data analysis application that receives status information from residential consumers and analyzes the status information. The system further comprises an electrical power price generation application that determines dynamic electrical power prices for the residential consumers based on the analysis of the status information, on an area of the residential consumers, wherein the electrical power prices of each area are determined independently. The system further comprises a power price distribution application that transmits the power prices to the residential consumers. The status information comprises one or more of when the last electrical price was received, what the last received electrical power price value was, how much load can be shed by the residential consumer, a control mode of an electrical power controller, and communication network diagnostic information.
