South Central Electric Companies Information Processing System

Eleven participants comprising the South Central Electric Companies (SCEC) have contracted to exchange large blocks of power with the Tennessee Valley Authority (TVA). Problems attendant on these operations are discussed as a prelude to presenting concepts developed for an information processing system to satisfy requirements for message switching, interchange schedule preparation, loss determination, and energy accounting among the participants. Typical input-output formats are discussed, followed by a description of the new Bell System 8A1 Data System and the UNIVAC 418 Real-Time Computer System, as applied to meet SCEC operating requirements.
