Exhibit 1 provides an overview of this supply chain. The focus of this primer is on the transmission and distribution segments: the power lines, substations, and other infrastructure needed to move power

A distribution system connects all the individual loads in a given locality to the transmission lines. Fig. 3.1, shows the Single Line Diagram of Electrical System of a very simple Electrical Power System.
Transmission lines move energy from power stations to substations. Power stations, — fueled by natural gas, wind, solar or other sources — make energy. Substations take that energy and either lower or
Simplified diagram of AC electricity distribution from generation stations to consumers. Transmission system elements are shown in blue, distribution system elements are in green.
The document summarizes the typical AC power supply system including generation, transmission, and distribution.
Distribution substations are available in various dimensions and designs. A little rural substation may possess a nominal rating of 5 MVA, but a metropolitan station may exceed 200 MVA.
Distribution substations come in many sizes and configurations. A small rural sub-station may have a nominal rating of 5 MVA while an urban station may be over 200 MVA. The figures show examples of

Electric power begins at a generating station, where the potential difference can be as high as 33,000 volts. AC is usually used. Users of large amounts of DC power such as some railway electrification systems, telephone exchanges and industrial processes such as aluminium smelting use rectifiers to derive DC from the public AC supply, or may have their own generation systems. High-voltage DC can be advantageous for isolati
Utilities may have some control over and access to the energy stored in electric vehicles attached to the grid.
