History of electric power transmission
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 (formally referred to as ""transmission""), and the delivery of electricity (""distribution"") to individual customers. The distinction between the two terms did not exist in early years and were used interchangeably.
