Wind Resource Mapping

9Wind resource mapping typically has two possible goals:

  • To analyse and present the wind resource for a region or an entire country, to be used in energy planning.
  • To map a smaller area within a region in order to optimise the layout of a wind farm.

Large scale wind resource maps

The calculation of large wind resource maps is a field where EMD has vast experience. As an example, EMD has made a detailed map of the Danish wind resource, where windPRO handled more than 8 million advanced WAsP calculations. The whole Denmark was calculated for 4 hub heights and with a grid resolution of 200 m. The calculation method was verified using production data from more than 1.400 existing wind turbines. The actual production for more than 80% of the turbines was within ±10% of the amount predicted using the wind resource map.

The methods developed in order to calculate the detailed wind resource map of Denmark can be used almost anywhere in the world.

The calculated resource map can be converted into the client’s preferred GIS, or an independent interface can be programmed for presentation and evaluation of the resource data. Maps will be produced in graphic format ready for poster print.

Local wind resource maps

Since 1999, EMD has calculated a large number of local wind resource maps for wind farm optimisation, covering sites all around the world. The procedure is almost identical to a Second Opinion study where the optimisation of the turbine layout is also required.
