ArcVera Renewables, one of the leading providers of consulting and technical services for wind and solar projects with more than 30 years of experience, has developed and published earlier this year an ambitious benchmark report that aimed to deliver a thorough analysis of the performance of its wind energy resource assessment (WERA) practice across a broad range of operating wind projects.
Based on a dataset composed of 31 projects it worked on in the US, combining 3.5GW of installed capacity and 212 years of operation, the report provides a detailed comparison between the pre-construction assessments using ArcVera’s advanced WERA practices and the actual post-construction energy production data.
The results of the study show that ArcVera’s wind assessment techniques are accurate within about 1 per cent on average of reported project P50 energy production, which becomes near zero mean bias after accounting for grid curtailment. In addition, the benchmark study indicated that ArcVera’s wind assessments have lower individual project performance variation than in the past.
