The interconnection of power systems, brought about by the economies and greater reliability of combined operations, has necessitated reliable communication both within and between power networks. This report surveys those communications systems and is based on information contained in the nine Regional Reliability Council Reports, filed with the FPC April 1. The more frequently utilized communication methods between control centers and major generating plants, substations and switching stations are: dedicated dispatch telephone circuits, independent or interpool leased teletypewriter networks, microwaves, radios, power-line carriers, and overhead insulated static wires. Approximately 98 percent of the major utilities have at least two independent communication systems. Communication channels between area control centers and regional coordination centers are principally teletype and local or long-distance telephone circuits, many of which are separate from Private Branch Exchange (PBX) equipment. About 70 percent of the reporting utilities have independent back-up for the primary channels. (MCW)
