They are not plugged into an outlet but instead are wired directly to the electrical power source. Conveyor belts are just one example of an electrical appliance used by industry. These customers use the same voltage that leaves the distribution substation. A small local furniture factory or a large shopping mall are examples. In British Columbia, we mainly use the power of falling water to make electricity.
Electricity is created inside a power plant.
A power plant that runs on water power is known as a hydroelectric dam . The electricity generated from the hydroelectric dam travels great distances over long wires called transmission lines. These transmission lines are held up by giant wood or metal transmission towers. When the electricity gets near your town, it goes into a substation. Substations are often surrounded by a wire fence to keep people away.
