Electricity supply refers to the process of generating and distributing electrical power to homes, businesses, and industries. This power is produced at power plants, which can use various energy sources such as coal, natural gas, nuclear, or renewable sources like solar and wind. Once generated, electricity travels through a network of transmission lines and substations to reach consumers. The electricity supply system is crucial for daily life, powering everything from appliances to industrial machinery. It operates on a grid system, ensuring that electricity is available when and where it is needed. Proper management and maintenance of this system are essential for reliability and efficiency.
