The process for electricity generation, transmission, and distribution requires a skilled workforce and considerable investment. The basics for electricity generation, which are produced through the turning of turbines, are the same for different sources of electricity such as electricity generated through coals, hydroelectricity, nuclear electricity, and renewable energy sources.

The generated electricity is then transmitted using the step-up transformers that increase the voltage. The high voltage electricity is then transmitted through the networks of electrically conductive wires.

The distribution of electricity is done via an electric distribution substation. At the substation, the high voltage electricity is passed through step-down transformers that lower the voltage. The lower voltage electricity is then transmitted to the network of local electric distribution lines.
