Wind Energy Production Reports

Wind Bankable Energy Production Reports

Bankable energy production reports provide developers, investors, and lenders with a thorough, objective, and well-documented evaluation of the energy production potential of a wind or solar project. UL has authored reports for nearly 100,000 MW of wind and solar plants worldwide, and our reports are widely respected and accepted in the financial community.

Bankable reports for wind energy projects include the following:

  • Site and project description – location, topography, land cover, technology description, and site visit record
  • Review of resource monitoring campaign – status and history of resource monitoring stations, significant events observed or reported
  • Data validation – description of data QC and validation method, period of record, problems or issues found, data substitution and reconstruction, overall data recovery percent
  • Observed resource characteristics – summary of the wind resource based on site measurements; includes monthly and annual mean speeds, wind roses, speed frequency distribution parameters, diurnal speed and shear patterns, turbulence; also temperature, air density
  • Long-term climate adjustment (MCP) – description of MCP method, reference stations or modeled data available and used, quality and consistency of reference data, long-term mean wind resource estimates
  • Extrapolation to hub height or rotor plane – analysis of shear patterns, observed or inferred changes with height, projection to hub height or across rotor plane
  • Wind flow modeling – description of wind flow modeling method, results of simulations for the site, validation using onsite data (if possible), estimated array-average wind resource
  • Plant description – turbine technology, power/thrust curve, layout
  • Losses – enumeration and justification of losses by category; description of the wake loss model; total estimated loss; first year and long-term losses; categories include
    • Turbine and plant availability; curtailments
    • Electrical system losses
    • Sub-optimal performance and power curve adjustments
    • Environmental losses (icing, soiling, etc.)
    • Wake losses (both internal and external to project)
  • Uncertainties – explanation of uncertainties by category, including measurement errors, MCP, shear and extrapolation, wind flow modeling, wake losses, and non-wake losses.
