Electric Power Transmission

Electric power transmission or "high voltage electrical transmission" is the bulk transfer of electrical energy, from generating plants to the end user. The rapid industrialization within the 20th century made electrical transmission lines and grids an important half of the infrastructure in most industrialized nations. Long-distance transmission of electricity (thousands of kilometers) is reasonable and efficient, with costs of US$0.005-0.02/kWh. This is the way energy is transferred from the source to the final end user.
