As electrification increases, the number of people with access to grid electricity is growing. The combined transmission and distribution network is part of electricity delivery, known as the " power grid" in North America, or just "the grid." In the United Kingdom, India, Tanzania, Myanmar, Malaysia and New Zealand, the network is known as the National Grid.Īlthough electrical grids are widespread, as of 2016, 1.4 billion people worldwide were not connected to an electricity grid. This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and potentially enabling more efficient electricity markets and redundant generation. Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s).electric power transmission to carry power long distances.electrical substations to step voltage up or down.
