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 company selling you power may be a not-for-profit municipal electric utility; an electric cooperative owned by its members; a private, for-profit electric utility owned by stockholders often called an investor-owned utility ; or in some states, you may purchase electricity through a power marketer.
A few federally owned power authorities—including the Bonneville Power Administration and the Tennessee Valley Authority , among others—also generate, buy, sell, and distribute power. Local electric utilities operate the distribution system that connects consumers with the grid regardless of the source of the electricity. Power plants generate electricity that is delivered to customers through transmission and distribution power lines.
High-voltage transmission lines, such as those that hang between tall metal towers, carry electricity over long distances to meet customer needs. Higher voltage electricity is more efficient and less expensive for long-distance electricity transmission. Lower voltage electricity is safer for use in homes and businesses. Transformers at substations increase step up or reduce step down voltages to adjust to the different stages of the journey from the power plant on long-distance transmission lines to distribution lines that carry electricity to homes and businesses.
At the beginning of the 20th century, more than 4, individual electric utilities operated in isolation from each other. As the demand for electricity grew, especially after World War II, utilities began to connect their transmission systems. These connections allowed utilities to share the economic benefits of building large and often jointly-owned electric generating units to serve their combined electricity demand at the lowest possible cost. Interconnection also reduced the amount of extra generating capacity that each utility had to hold to ensure reliable service during times of peak demand.
Over time, three large, interconnected systems evolved in the United States. The stability of the electricity grid requires the electricity supply to constantly meet electricity demand, which in turn requires coordination of numerous entities that operate different components of the grid. Local electricity grids are interconnected to form larger networks for reliability and commercial purposes. At the highest level, the U.
The Eastern Interconnection encompasses the area east of the Rocky Mountains and a portion of the Texas panhandle. The Western Interconnection encompasses the area from the Rockies to the west. The network structure of the interconnections helps maintain the reliability of the grid by providing multiple routes for power to flow and allowing generators to supply electricity to many load centers.
This redundancy helps prevent transmission line or power plant failures from causing interruptions in service to retail customers. Click to enlarge. The three interconnections describe the large-scale physical structure of the grid. The regional operation of the electric system is managed by entities called balancing authorities, which ensure that electricity supply constantly matches power demand. Most of the balancing authorities are electric utilities that have taken on the balancing responsibilities for a specific part of the power system.
All of the regional transmission organizations in the United States also function as balancing authorities. ERCOT is unique in that the balancing authority, interconnection, and the regional transmission organization are all the same entity and physical system.
A balancing authority ensures that electricity demand and supply are finely balanced to maintain the safe and reliable operation of the power system. If demand and supply fall out of balance, local or even widespread blackouts can result.
Balancing authorities maintain appropriate operating conditions for the electric system by ensuring that a sufficient supply of electricity is available to serve expected demand, which includes managing transfers of electricity with other balancing authorities. Electric utilities are responsible for maintaining the safety of their systems and planning for the future power needs of their customers. Initially, the electric power industry developed voluntary standards to ensure coordination of linked interconnection operations.
Today, mandatory reliability standards for planning and operating power systems and for addressing security concerns at critical electrical infrastructure are in place. In Canada, Canadian regulators fill this role. The smart grid incorporates digital technology and advanced instrumentation into the traditional electrical system, which allows utilities and customers to receive information from and communicate with the grid.
A smarter grid makes the electrical system more reliable and efficient by helping utilities reduce electricity losses and to detect and fix problems more quickly.
The smart grid can help consumers intelligently manage energy use, especially at times when demand reaches significantly high levels or when a reduced energy demand is needed to support system reliability. Smart devices in homes, offices, and factories can inform consumers and their energy management systems of times when an appliance is using relatively higher-priced electricity.
These alerts help consumers, or their intelligent systems, to optimally adjust settings that, when supported by demand reduction incentives or time-of use electricity rates, can lower their energy bills.
Smart devices on transmission and distribution lines and at substations allow a utility to more efficiently manage voltage levels and more easily find out where an outage or other problem is on the system. Smart grids can sometimes remotely correct problems in the electrical distribution system by digitally sending instructions to equipment that can adjust the conditions of the system.
Construction of electricity infrastructure in the United States began in the early s and investment was driven by new transmission technologies, central station generating plants, and growing electricity demand, especially after World War II. Now, some of the older, existing transmission and distribution lines have reached the end of their useful lives and must be replaced or upgraded. New power lines are also needed to maintain the electrical system's overall reliability and to provide links to new renewable energy generation resources, such as wind and solar power, which are often located far from where electricity demand is concentrated.

An electrical grid , electric grid or power grid , is an interconnected network for delivering electricity from producers to consumers. It consists of: . 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. A bulk-power transmission network is therefore used to move the power long distances, sometimes across international boundaries, until it reaches its wholesale customer usually the organisation that owns the local electric power distribution network. The electric power is therefore stepped up to a high voltage for the electric power transmission system.
