Electricity networks are systems that deliver electrical power from producers to consumers. They consist of various components, including power plants, transmission lines, substations, and distribution lines. These networks ensure that electricity generated from sources like solar panels, wind turbines, or fossil fuels reaches homes and businesses efficiently. The main parts of an electricity network include the high-voltage transmission system, which transports electricity over long distances, and the lower-voltage distribution system, which delivers power to end users. Proper management of these networks is essential for maintaining a reliable supply of electricity and preventing outages.
