A system for electric power demand monitoring and control includes one or more data distribution networks interconnecting intelligent utility units located at customer homes with a host computer located in the utility company offices. Each intelligent utility unit is associated with a customer home for connecting and disconnecting a power service meter, monitoring customer demand, and controlling power to selected units. A network within the home interconnects each intelligent utility unit with power consuming units for providing data on power usage and power control. A data distribution network interconnects the plurality of intelligent utility units to the host computer as a head end unit, the data distribution network providing downstream communication channels from the host computer to the plurality of intelligent utility units and upstream communication channels from the plurality of intelligent utility units to the host computer. The communication channels are organized as frequency division multiplex channels in a frequency spectrum. A plurality of distribution networks can be provided for a larger utility environment with each distribution network associated with a power substation and customers served by the power substation.
