interconnected network for delivering electricity from suppliers to consumers
An electrical grid is an interconnected network of power lines, substations, and equipment that delivers electricity from suppliers (like power plants) to consumers' homes and businesses. It matters because it's the system that reliably brings the electricity we depend on for lighting, heating, computing, and countless other daily needs to where we need it.

An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined transmission and distribution network is part of electricity delivery, known as the power grid.
