Re-assessment of energy production

Site: medium size wind farm in Eastern Germany Procedure:  profound analysis of SCADA data and monthly production data wind measurement with a Sodar instrument used for comparison purposes comparison of all data with a neighbouring wind farm model calculations Results: reduction of the long term mean energy production has a significant contribution to the overall

Performance check of wind turbines

Site: medium size wind farm in Belgium Procedure: combination of analyses of SCADA data and a nearby wind measurement comparison to reanalyses data, met station data and aj production indices Results: inconsistencies related to the power curve could be detected in the past, including longer periods with reduced availabilities and a variety of curtailments more

Re-assessment of energy production

Site: medium size wind farm in Northern Germany; the real energy production is much lower than calculated in the original assessment report Procedure: profound analysis of SCADA data Results: reduction of the long term mean wind resource, albeit its contribution to the overall result is small compared to the following aspects thrust coefficients too low

Re-assessment of wake losses

Site: small wind farm in Germany; the client assumes distinctly higher wake losses than calculated in the original assessment report Procedure: profound analysis of SCADA data, adapted model calculations Results: the met station data used in the wind assessment report turned out to be less appropiate for the site, which is influenced by very local
