How Does the Power Grid Work?

Because these plants are often located in rural areas, the electrical energy needs to be transmitted efficiently across long distances. Once the electrical power nears more populated areas, it’s then again stepped back down by a transformer at a substation to safer levels. Feeder lines connect residential houses to the transmission lines and the pylons which carry them. However, this isn’t the case everywhere — in some regions, power lines are instead buried in a process called “ undergrounding .” Underground power lines, though more expensive, have the significant advantage of being less susceptible to weather conditions. Electricity is directed via the grid byPrivate companies and public utilities participate in power generation and transmission as well.
