AEP's Anatomy of a Transmission System

Electricity takes quite a journey before it arrives at your home or business. It's generated at a power plant, transported through a transmission system and distributed through power lines and equipment in your neighborhood. Learn more about how the transmission part of the journey happens and how to stay safe, especially around transmission towers and substations. This factsheet has all the details.
