Wind atlas

Also, an overview of our most important wind atlases incl. their model grids is available via our atlas grid tool within awis.

For an initial estimation based on the anemos wind atlases, our experts assess the wind conditions at your site* and, on request, the energy yield and possible losses. You receive a signed report.

The initial estimation assists you with the decision for the correct measurement location, can form the basis for turbulence calculations and allows you to compare different WTG types.

The initial estimation can contain:

• mean wind speed and optionally mean energy yield (20 years)
• frequency distribution of wind speed and wind direction
• directional Weibull distribution
• annual cycle of wind speed and optionally energy yield
• consideration of wake effects plus further losses
• .tab file for application in WAsP, WindPRO, Meteodyn, etc.

The results you need depend on your project. We agree the scope with you, from the wind statistics alone to an estimate of the energy yield including losses.

When planning a wind farm, the optimization of the layout, i.e. the arrangement of the individual wind turbines within a wind farm, is of crucial importance. A well designed layout maximizes the energy yield and minimizes the ecological impact. We accompany your project in the initial stages and are able to support you in planning a yield-optimized layout based on our site-specific wind atlas time series.

The following points are important:

• Spacing and placement: Optimal arrangement of the wind turbines to achieve the highest possible energy yield.
• Consideration of environmental factors: Minimizing the ecological impact by taking site conditions and legal requirements into account.
• Simulation and modeling: Precise analysis and modeling of different scenarios for the best result.

We can analyze the optimal use of the available space in a relatively short time and provide you with a recommendation for a layout. Several variants (different wind turbine types) can be compared with each other. An initial assessment of wake losses is also made. This maximizes yields while minimizing turbulence and loads.

In our web tool awis, you can retrieve the wind statistics for your site directly online with the wind potential product: fast and cost-effective. The results are calculated automatically from the anemos wind atlases, without processing by an expert.

You receive:

• site-specific* wind speeds
• Weibull parameters A and k
• wind rose with 12 or 36 wind direction sectors
• frequency table of wind speed by wind direction sector
• histogram of wind speed
• Excel table with all values for download
• automatically generated PDF report for your site with all results

As an additional service, we also prepare the statistics with a temperature filter that only considers values below a certain temperature, e.g. for ice throw assessments.

Do you need an expert opinion, e.g. because our experts should take a closer look at the site or make adjustments, or a signed report? Then the initial estimation based on wind atlases is the right choice for you.

Do you need a quick estimate of energy yield for diverse specific wind turbine generators? Our anemos production atlas calculates the energy yields with your given power curves and hub heights.

Therefore, the production atlas allows a comparison between different WTG technologies. Plus, it is a tool for selecting a suitable wind farm site or for expanding your portfolio.

Gladly, we generate wind farm specific production time series for you which consider your given wind farm configuration and losses.

You receive the production data either as site-specific* time series or as map(s) of the mean energy yield of the last 20 years; available with 90 m x 90 m resolution (for Germany and France)

We determine an initial estimation of the energy yield for your planned wind farm. The following analysis can be done with the product:

• Comparison of energy yields of planned turbines with different configurations of type, hub height or coordinates
• Guide value as a first estimate
• Relative comparison of different sites with planned turbines with the same configuration
• Energy yield drop due to building of additional turbines

Additionally, the product awis energy yield calculation is excellent for the calculation of wake losses due to surrounding wind turbines. The product is especially suitable for:

• Wake losses of planned turbines in an existing wind farm
• Wake losses of a planned wind farm
• Future wake losses of existing turbines due to planned turbines
• Comparison between the wake losses of different configurations

On request we consider e.g. further restrictions or an adaption to measurements or energy yield data, respectively.

Do you need an expert opinion, e.g. because our experts should take a closer look at the site or make adjustments, or a signed report? Then the initial estimation based on wind atlases is the right choice for you.
