Pathway of Power: Transmission System

High-voltage electricity is moved over distance through the transmission system. Transmission lines are interconnected to form a network. Should one line fail, another will take over the electric load. Transmission lines can be overhead or underground.

All transmission lines carry three-phase current, or three separate streams of electricity traveling along three separate conductors (see diagram #3).

The transmission system is interconnected with transmission systems of other electric utility companies in the state. If we need an emergency supply of electricity or if another company needs our electricity, we can send or receive power through a statewide network of transmission lines.
