Amprion publishes data on forecast and actual generation of wind energy feed-in according to Section 17, paragraph 1, no. 8 (StromNZV). The values of the anticipated grid feed-in are based on the forecasts, exchanged for the management of immediate horizontal exchange among transmission system operators. The values of actual energy feed-in correspond to a short-term extrapolation based on a limited number of metered reference wind energy plants. The data described are not relevant for the annual settlement according to Section 14 of the German Renewable Energy Act (Erneuerbare-Energien-Gesetz = EEG). The actual energy input data relevant for the annual settlement can only be obtained from the data report according to Section 14, paragraph 6 EEG by 30 April and their certification by 30 June of the following year.
