How Electricity Is Delivered

Electricity Is Delivered to Consumers Through a Complex Network of Transmission and Distribution Lines

Power is generated at power plants and then moved to substations by transmission lines—large, high-voltage power lines, often supported by tall metal towers. In the United States, the network of nearly 160,000 miles of high voltage transmission lines is known as the “grid.”

A local distribution system of smaller, lower-voltage distribution lines—often supported by wood poles—then moves power from substations and transformers to customers.
