Extrapolated actual wind power feed-in
The actual wind power feed-in values in the 50Hertz control area presented in the chart are determined by extrapolation on the basis of current values from selected wind farms.
The 15-minute average resulting from the extrapolation is published as power feed-in in MW for the respective 15-minute period. Any 15-minute period for which no or implausible values are at hand will be qualified "not available" (n.a.) until the end of 2008, and will be stated at -1 beginning in 2009.
