WebThe majority of major transmission lines in the U.S. are either 230-kilovolt ( kV) or 500-kV alternating current lines. In some cases, 115-kV lines are used. Lower voltages are far less efficient for moving electricity across hundreds or thousands of miles to where it is needed without losing a significant amount of energy. Transmitting electricity at high voltage reduces the fraction of energy lost to Joule heating, which varies by conductor type, the current, and the transmission distance. For example, a 100 mi (160 km) span at 765 kV carrying 1000 MW of power can have losses of 0.5% to 1.1%. See more Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a … See more Commercial electric power was initially transmitted at the same voltage used by lighting and mechanical loads.
