The term electricity supply refers to the delivery and distribution of electrical power from generating sources, such as power plants or renewable energy systems, to end-users through a network of wires, cables, transformers, and other equipment. This includes maintaining adequate levels of generation capacity, ensuring reliable transmission and distribution infrastructure, and managing the overall flow of electricity from producers to consumers in an efficient manner. The quality, reliability, cost-effectiveness, and sustainability of electricity supply are important factors that can impact economic growth, social development, and environmental wellbeing.
