Stromsee model
The term Stromsee-Modell has become established for a model that is intended to clearly represent the current situation of electricity generation and the market to electricity customers . The term Stromsee is primarily used as a marketing term for unused supply surpluses between electricity suppliers and electricity-dependent devices (end consumers).
Definition of terms
The reason for the definition of the Stromsee model is the public discussion about electricity generation from fossil fuels on the one hand and from renewable energies on the other. The second form is often referred to as “ green electricity ”, but this term has not yet been defined or protected by law.
The explanatory model depicts the river as a lake that serves as a reservoir for all the electricity produced by the producers. There is no difference in what type of electricity it is: from nuclear energy , crude oil , gas or coal or from renewable energies such as wind, sun, water and biomass. The status of the energy producer also plays no role in the Stromsee; it ranges from large corporations to private operators of small wind farms or photovoltaic systems .
The lake of electricity exists constantly and holds electricity ready for consumption. The almost 1,000 producers are in a sense on one bank of the lake and the consumers who receive electricity from the lake on the other bank. Electricity is available at all times, regardless of which source it comes from and from which provider a customer obtains it. If a consumer wants to receive electricity from renewable energies , he switches to a producer of green electricity . To do this, he does not have to make any structural changes to his house or apartment and the electricity comes to him in the same way as before. The energy comes from the Stromsee and therefore consists not only of "clean" electricity, but also of the use of conventional fuels . The consumer actively influences the mixing ratio of the lake.
Weaknesses of the model
Contrary to what the term lake suggests, the Stromsee has no storage effect . For the model, this would mean that one would have to imagine an extreme steppe lake with a depth of 0 millimeters. Only as much energy can be fed into the grid (or the lake of electricity) as is needed at the moment (law of conservation of energy ), as adequate energy storage is currently not available.
In the usual representations and descriptions, the model does not take into account the lossy distances to be bridged between producers and consumers.
