The history of the technology of moving electricity far from where it was generated dates from the late 19th century. This includes movement of electricity in bulk, and the delivery of electricity to individual customers. The distinction between the two terms did not exist in early years and were used interchangeably. Prior to electricity, various systems have been used for transmission of power across large distances. Chief among them were telodynamic, pneumatic, and hydraulic transmission. Cable cars were the most frequent example of telodynamic transmission, whose lines could extend for several miles for a single section.
