Energy Yield Assessment

Services for Banks, Wind Farm Investors, Project Developers and Operators

For many years, DEWI has been one of the leading international consulting companies. DEWI’s expertise and the worldwide acceptance of the reports prepared by DEWI experts are the results of high-quality analyses of numerous national and international wind farm projects.
 

  • Detailed analysis and correction of measured on-site data regarding the measurement set-up, calibrations, anemometer characteristics or possible inconsistencies
  • Analysis of the long-term wind conditions based on detailed correlation procedures and extensive verification of the consistency of long-term wind data
  • Detailed uncertainty analysis with specification of the production P-level (P50, P90, Pxx), which provides the input for a reliable risk assessment
  • In-depth assessment of the wind turbine class in line with IEC 61400-1 ed. 2 and ed. 3 depending on the wind turbine suitability for the site
  • Site specific wind farm optimisation with regard to the energy yield
  • Professional GIS analyses and in-depth site assessment
  • Qualified consultancy to conduct an efficient measurement campaign to improve the project basis
  • Review and applied analyses of high-resolution operational data
  • Worldwide experience and contacts in research, evaluation, data verification and long-term correlation of meteorological data
  • Research and development on correlation procedures, long-term wind conditions, flow simulation
  • Relevant work for various standards (MEASNET, IEC, FGW, etc.)
  • Comprehensive experience in application and assessment of 3D computational fluid dynamics (CFD) calculations for simulation of wind and turbulence conditions
  • Well-founded methods for calculation of wind and turbulence conditions, energy yield and wind farm efficiency with different models, determination of extreme wind conditions, analyses of noise emissions and shadow flicker impact
  • Accredited according to ISO/IEC 17025:2005 for “Site and area related wind potential and energy yield assessments for single wind turbines and for wind farms” (DEWI, Oldenburg)
