The document describes the process of electric power transmission and distribution from power plants to end users. Electricity is generated at power plants using fossil fuels or renewables, transformed to high voltage for transmission, distributed through substations that lower the voltage, then finally stepped down for local use through transformers and circuits to homes and businesses where meters track electricity usage for billing.
