Wind Resource Assessment

DTU Wind and Energy Systems (DTU Wind) offers consultancy services for regional wind climate mapping and project related wind resource assessment.

DTU Wind has developed the Wind Atlas Methodology and WAsP, which is the industry-standard for wind resource assessment, siting and energy yield calculation for wind turbines and wind farms. We have a long track record as consultant in wind resource assessment, which has been part of our services in several wind energy projects, carried out around the world.

A wind resource assessment estimates the wind climate (e.g. wind direction frequency distribution, wind speed distribution, temperature, air density, power density) as well as the potential energy yield of a wind turbine or a wind farm in a region or at a proposed site. Calculations are made applying the WAsP and WAsP CFD software packages.

The work will involve at least the following main tasks:

• Collection of data and information, i.e. generation of all necessary inputs to the analyses, which normally requires a site visit by an expert from DTU Wind
• Analyses and reporting, which most often will be done home-office at DTU Wind’s Risø campus

The report will contain a full documentation of the background, data and inputs used for the analyses. The resulting wind atlas will be a representation of the wind climate of the region containing information regarding estimated wind conditions, power density of the wind flow, and potential energy yield of wind turbines. Finally, the energy yield of the individual wind turbines in a wind farm are estimated taking account of the interaction between wind turbines, i.e. the wind farm array efficiency or wake losses. The report will include an estimation of the uncertainties of results.
