The purpose of this paper is to present a strategic view on the future of the oldest type of communications in power transmission electrical grids – high voltage power line carrier (PLC) along transmission electrical power lines 35…500 kV. It provides analysis of development stages and nowadays conditions of the high voltage PLC. It discusses prospective areas for development of PLC systems and channels for voice and longtime electrical lines condition monitoring based on discrete multi-tone modems. It suggests variants of high voltage PLC channels application considering future specifics of creating telecommunications networks for transmission companies.
