Generation - Utilities produce electricity at power plants by burning fuels (such as coal, natural gas, oil, and biomass fuels like wood) and by operating hydroelectric and wind facilities. Utilities also purchase electricity from other utilities or power
suppliers. |
Transmission - High-voltage electricity travels from power plants along transmission lines to distribution substations. |
Distribution - At distribution substations, the voltage is reduced and low-voltage electricity is delivered to customers. The amount of electricity is metered to measure customer usage levels.
