Wind power

Wind power in Germany is leading the way in the field of renewable electricity generation. There are now wind turbines in Germany with an installed capacity of around 39,386 megawatts. 50Hertz already feeds into the grid around 38 percent of the installed wind power capacity in Germany. This also involves balancing the high wind-related fluctuations in power feed-in.

Wind power currently accounts for around eight percent of gross electricity consumption in Germany. In contrast to conventional power plants, however, electricity generated with wind turbines is subject to strong fluctuations. As a consequence, it is seldom that the electrical energy generated with wind corresponds to the respective demand. However, in accordance with the Renewable Energies Act (EEG), the operators of Germany’s power grids are required to take off all electricity fed into the grid by renewables-based generators. In order to balance supply and demand, operators must balance the high wind-related fluctuations.

50Hertz ensures this balance is maintained. This mainly involves balancing wind power, for which the forecast feed-in must be compensated.

The high wind-dependent fluctuations in fed-in power determine the compensation energy requirements and are thus a key cost driver.

Below, you will find a number of important key figures relating to wind energy in the 50Hertz control area.
