2021 levy for wind turbines
Special provisions apply to onshore wind turbines that were being subsidized at the end of 2020: They are entitled to a levy on the feed-in tariff (amendment to Section 23b EEG 2021 of 27.07.2021).
This levy amounts to 0.25 to 1.00 ct/kWh on the monthly market value for onshore wind energy. System operators who meet the relevant statutory conditions can claim it (Section 23b (2) to (5) EEG 2021).
