Transmission and Distribution

With “centralized generation”, transmission lines transport large amounts of high voltage electricity produced at centralized power plants to substations where the electricity is converted to a lower voltage.  Then, distribution lines carry the lower voltage electricity to consumers.  With “distributed generation”, the source of electricity is at or near the customer, such as solar panels on a residential home or business.

Transmission towers are generally tall metal structures that separate high-voltage power lines from their surroundings.


  • Conductors (Power Lines)

Conductors are the power lines that carry the electricity to and through the grid to customers.

Substations consist of structures, conductors, fencing, and lighting and serve as the area where very high voltages used for electric transmission are converted to lower voltages for consumer use.



  • Right of WayiStock_000017024151Large copy

The right of way encompasses land set aside for transmission lines and are cleared of vegetation to avoid the risk of fires and other accidents.

Access routes are normally paved or gravel roads cleared of vegetation for easy access to transmission lines and associated facilities.
