Electric power transmission

Electricity is generated at power plants and moves through a complex system, sometimes called the grid , of electricity substations, transformers, and power lines that connect electricity producers and consumers. Most local grids are interconnected for reliability and commercial purposes, forming larger, more dependable networks that enhance the coordination and planning of electricity supply. In the United States, the entire electricity grid consists of hundreds of thousands of miles of high-voltage power lines and millions of miles of low-voltage power lines with distribution transformers that connect thousands of power plants to hundreds of millions of electricity customers all across the country. The origin of the electricity that consumers purchase varies. Some electric utilities generate all the electricity they sell using just the power plants they own. Other utilities purchase electricity directly from other utilities, power marketers, and independent power producers or from a wholesale market organized by a regional transmission reliability organization. The retail structure of the electricity industry varies from region to region.

The most important promise made by the proprietors of 5G wireless technology -- the telecommunications service providers, the transmission equipment makers, the antenna manufacturers, and even the server manufacturers -- is this: Once all of 5G's components are fully deployed and operational, you will not need any kind of wire or cable to deliver communications or even entertainment service to your mobile device, to any of your fixed devices HDTV, security system, smart appliances , or to your automobile. If everything works, 5G would be the optimum solution to the classic "last mile" problem: Delivering complete digital connectivity from the tip of the carrier network to the customer, without drilling another hole through the wall. Also: Should 5G be in your IT budget? The "if" in that previous sentence remains colossal. The whole point of "Gs" in wireless standards, originally, was to emphasize the ease of transition between one wireless system of delivery and a newer one -- or at least make that transition seem reasonably pain-free.

An electrical grid , electric grid or power grid , is an interconnected network for delivering electricity from producers to consumers. It consists of: [1]. Electrical grids vary in size from covering a single building through national grids which cover whole countries to transnational grids which can cross continents. Power stations connected to grids are often located near energy resources such as a source of fuel or to take advantage of renewable energy resources, and away from heavily-populated areas.

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant , to an electrical substation. The interconnected lines which facilitate this movement are known as a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery , known as the " power grid " in North America , or just "the grid". A wide area synchronous grid , also known as an "interconnection" in North America, directly connects many generators delivering AC power with the same relative frequency to many consumers.
