![]() Interconnections allow for economies of scale, allowing energy to be purchased from large, efficient sources. Electric utilities across regions are many times interconnected for improved economy and reliability. Finally, upon arrival at the service location, the power is stepped down again from the distribution voltage to the required service voltages.įig.: As the 21st century progresses, the electric utility industry seeks to take advantage of novel approaches to meet growing energy demand. As it exits the substation, it enters the distribution wiring. On arrival at a substation, the power will be stepped down from a transmission level voltage to a distribution level voltage. The electric power which is generated is stepped up to a higher voltage at which it connects to the electric power transmission network, until it reaches its wholesale customer or usually the company that owns the local electric power distribution network. Power stations may be located near a fuel source, at a dam site, or to take advantage of renewable energy sources, and are often located away from heavily populated areas. It consists of generating stations that produce electrical power, high-voltage transmission lines that carry power from distant sources to demand centers, and distribution lines that connect individual customers. ![]() ![]() INTERCONNECTED GRID TRANSMISSION NETWORK An electrical grid is an interconnected network for delivering electricity from suppliers to consumers. ![]()
