How Electricity Gets Into Our Homes

Power Grid

Electricity is generated at power plants, which can use a variety of fuels such as coal, natural gas, nuclear, hydro, wind, and solar energy to generate electricity. Once generated, the electricity is transmitted over long distances through a network of high-voltage power lines, known as the power grid.

The power grid is managed by utility companies, which distribute the electricity to homes and businesses through a system of lower-voltage power lines and transformers.

When the electricity reaches your neighborhood, it is delivered to a distribution transformer that reduces the voltage to a level that can be safely used in homes and businesses. From there, the electricity is distributed through underground or overhead power lines to individual homes and businesses, where it enters the building through a service drop or service lateral.

Inside the building, the electricity passes through a meter that measures the amount of electricity used, and then enters a circuit breaker panel or fuse box, where it is distributed to various circuits throughout the building. These circuits supply power to outlets, appliances, lighting, and other electrical devices in the home.
