The expansion of electricity generation from wind power has been booming for 20 years. More precisely: since the Renewable Energy Sources Act (EEG) came into force. It was only this promotion, introduced at the beginning of the 2000s, that really brought sustainable power generation forward. But soon the financial support for the first wind power plants, which is limited to two decades, will be phased out.
Because they have now been financially amortized, many plants could continue to feed electricity into the grid at low cost. For the operators, this would be an additional return, as they had calculated a lifetime of only 20 years. Whether a turbine is technically suitable for further operation, however, must be answered clearly.
