Determination of site quality after commissioning (TR10)


The site quality of a wind turbine (wtg) determines the amount of compensation a wind turbine gets, if it is promoted under the Renewable Energy Sources Act (EEG).
The ratio between site specific energy yield and reference energy yield is called site quality. While the reference energy yield is fixed, the site energy yield can change during the operating time of a wind turbine.
Since the introduction of the tendering procedure and the single-staged reference energy yield procedure with the EEG 2017, the site energy yield must be redetermined after 5, 10 and 15 years of operation. The remuneration can then be adjusted on the basis of the newly determined site energy yield. This can also lead to retroactive back payments or refunds if the site quality changes by more than 2 %.
According to the EEG 2017 only accredited testing laboratories are permitted to determine the site quality after commissioning. A requirement for accreditation is the regular successful participation in round robin tests of the Fördergesellschaft Windenergie und andere Dezentrale Energien (FGW e.V.).
anemos is accredited for the determination of site quality after commissioning, as well as for the determination of site quality before commissioning (see Certificate of participation in the TR 10 round robin test Rev. 2.0). On the basis of this accreditation, anemos is authorized to issue corresponding test certificates that can be presented to the grid operator.
