Electric Lines

Electricity is usually sent over long distances through overhead electical transmission lines (such as those in the photo on the right). Underground power transmission is typically used only in densely populated areas (such as large cities) because of the high capacitive and resistive losses incurred, and because of cost.

Electric power transmission is one process in the delivery of electricity to consumers. The term refers to the bulk transfer of electrical power from place to place. Typically, power transmission is between the power plant and a substation near a populated area. Due to the large amount of power involved, transmission normally takes place at high voltage.

Electrical distribution is the final stage in the delivery of electricity and is concerned with the delivery from the substation to the consumers. It is generally considered to include medium-voltage power lines, electrical substations and pole-mounted transformers, low-voltage distribution wiring and sometimes electricity meters.

The Office of Energy is responsible for environmental permitting for both electric transmission and distribution projects.
