Load management systems. [Automatic Meter Reading and Control (AMRAC)]
National concern for energy conservation and the increasing cost of electric generating capacity are accelerating interest in load-management systems having the potential to influence daily load profiles. Load-management functions can best be performed by a centrally controlled system. Just as central control of the load management system by outward communication is advantageous, central collection of data by inward communication also adds value. If central control and two-way communication are to be used, some means of communication must be provided between the central location and each end user. General Electric's Automatic Meter Reading and Control (AMRAC) system uses distribution line carrier because it is economical and information can be transmitted in both directions. A small version of this rudimentary meter-reading system, known as AMRAC Phase I, was installed on line for Philadelphia Electric in late 1974 and 1975 to test the encoder and communication. By mid-1976 the next generation of AMRAC equipment became available. Units were installed and operating on six utility systems before the end of that year. The success of Phases I and II has now fostered the demand for commercial production of the equipment. General Electric is in the process of implementing a Phase III AMR-AC system. (MCW)
