The Confederation may restrict or prohibit the consumption of electrical power. Appliances, systems or light sources that are not absolutely necessary, such as shop window, advertising or public lighting, can be completely switched off. The actual list of all prohibited power-consuming devices depends on the degree of undersupply and is released by the government when the measure comes into force.
Although only a small proportion of electrical power can be saved by employing this measure, it has a great psychological impact in terms of self-discipline. It makes it clear to everyone that the country is in an exceptional situation. In addition, in order to reduce peak demand, the times at which production processes occur can be adjusted (e. g. producing only at night) and set in specific agreements with large consumers.
