Steam or some other form of energy is used to rotate turbines.

Energy

Rotating turbines cause generator to rotate.

Turbine

Rotating generator creates electrical current.

Generator

Transmission Substation

uses large step-up transformers to convert the generator's voltage up to extremely high voltage for long-distance transmission on the transmission grid.

High-voltage Transmission Lines

move the electric current generated from the power plant to the power substation.

Power Substation

Power Substations

uses step-down transformers to decrease the voltage of the current. This current is still at a high voltage.

Transformer Drum

reduces voltage to a level that can be used in the house (220 volts).
