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.

Abstract
An energy meter at an electrical substation contains a detector which chas state each time a quantity of energy is consumed. This data is accumulated in a microprocessor system. Real time energy consumption data is fed back to a customer monitoring station and may be telemetered to a power company central billing station. Customer and power company have their demand periods synchronized by the microprocessor system.
