Standard work capacity
The standard energy capacity ( RAV for short ) is used in the energy supply as a measure of electricity generation . It indicates how much electrical energy can be supplied by a power plant in a certain period of time (usually one year) . It thus represents an average performance figure that was provided in the selected period or is forecast for this. It is usually given in the equivalent units GWh per year or million kWh per year.
The availability of energy sources such as hydropower and wind energy is subject to annual fluctuations. Electricity production follows these fluctuations. To compensate for this, the standard energy capacity is calculated. This represents the realistic, average yield and is the mean value of the annual production of a connected series of as many, at least three, years as possible.
In order to be able to make statements about its economic efficiency when planning a power plant , the normal energy capacity is forecast from the average water flow or the average wind speed in this phase .
