The Electric System

There are various components that are needed to create, transmit, and distribute electricity. The following graphic identifies and describes those various components.

	Electricity is generated at one of the many different power plants located throughout the region.
	Electricity travels from the power plant over high-voltage transmission lines to substations.
	At a substation, the electricity voltage is lowered so that it can travel over the distribution system.
	Transformers, both aerial and underground, reduce the electricity voltage even further so it can be accepted by the home or business.
	Service lines carry electricity to the home or business.
