Miesbach–Munich Power Transmission was the first[1] transmission of electrical energy over a large distance.
It took place in 1882 between a steam engine situated near Miesbach and the glass palace of Munich, where world's first international electricity exhibition took place. The voltage used was 2000 V direct current, and the distance 57 kilometres. Only 2.5 kilowatts of power was transmitted, which was used to run an artificial waterfall. The system was designed by Oskar von Miller and Marcel Deprez.[2].
