is the minimum level of electricity demand required over a period of 24 hours. It is needed to provide power to components that keep running at all times (also referred as continuous load).


Let’s assume that the electrical grid is a big household. Under normal circumstances, the power required by the electrical grid is fairly constant during various period of the day. This constant power, which is required at all times, is called the base loading.

Power plants that generate the base load and feed it into the power grid are also called base-load power plants. The power plants for generating the base load are in operation almost 24 hours a day.

But where does the base load actually come from? The base load is mainly generated by consumers that are in use around the clock – for example, refrigerators or standby devices. However, there are also devices and systems outside of private households that are constantly in operation and thus increase the base load, for example the railroad or production facilities in factories.
