    Electricity flows from a power plant through high-voltage transmission lines.
  • 2
    At substations, transformers reduce voltage and re-route electricity to main feeder lines, or circuits, that take power into the community. Each feeder line is protected by a circuit breaker.
  • 3
    Lateral lines connected to main feeder lines route electricity through smaller areas like neighborhoods and subdivisions.
  • 4
    Nearing the end of the line, transformers on individual poles reduce voltage and distribute electricity to homes and businesses. Typically, one transformer services about four homes.
  • 5
    The electric connection at your house or business is the last stop for electricity.
