Wind energy expansion in Germany

 

The Electricity Feed-In From Renewables Act of 7. 12. 1990, the forerunner of the Renewable Energy Act (REA), obliged electricity supply companies (ESCs) to purchase electricity generated from renewables and guaranteed electricity producers minimum tariffs. The Figures show the nominal power of the WTs installed in Germany year-by-year since 1990. Installed offshore wind capacity reaches for the first time almost 1 GW in 2014 and increases in the following years.

The following graph shows the cumulative installation during the year, giving a preliminary overview of the pure expansion, excluding the end of operation of old turbines.  Only at the beginning of the following year can reliable figures for the expansion be presented. Nevertheless, this chart provides a good trend display.
