A power grid is a network that delivers electricity from producers to consumers. It consists of power plants, transmission lines, and substations that work together to ensure that homes, businesses, and industries have the energy they need. The grid helps balance electricity supply and demand, making sure that when you flip a switch, the lights turn on. In many countries, the power grid is managed by organizations that monitor and control the flow of electricity. These organizations ensure that the grid remains stable and can handle unexpected events, like a sudden increase in demand or a power outage. This reliability is crucial for everyday life and economic activities.
