1. A microprocessor system for enabling remote billing by a power supplier of customer power consumption comprising:

  • peripheral interface means for receiving power consumption data as a function of a preselected scale factor and transmitting it along a data bus;

    memory means connected to the data bus for storing the power consumption data;

    monitoring means connected to the output of the peripheral interface means for providing power consumption data to a customer;

    display means connected to the output of the peripheral interface means for selectively displaying stored data to a system operator;

    means connected to the input of the peripherals interface means for allowing manual accessing of the data by the operator; and

    asynchronous communications interface means connected to the data bus for transmitting data in the memory means, to data lines thereby enabling a central station at opposite ends of the data links to compute billing; and

    a central processing unit connected to the data bus for controlling the operation of the peripheral interface and asynchronous communications interface means as well as the memory means;

    first clock means connected to the central processing unit for clocking the unit through its operation, and,second clock means connected to the central processing unit for synchronizing a preselected demand period for both customer and power supplier.
