Most wind energy resource studies start with a top-level theoretical resource, which is progressively reduced through consideration of so-called constraints. This is typically expressed as Region X having a wind energy potential of Y units of energy per year. Employing assumptions on the technology conversion efficiency to units of energy, it is possible to derive an energy estimate that corresponds to a defined area. This is usually computed in a Geographical Information System (GIS). They do not substitute for anemometry measurements – rather they serve to focus investigations and indicate where on-site measurements would be merited.Īs a further stage in investigations, theoretical wind turbines can be placed in a chosen spacing, within a geographical model containing wind speed values as a gridded dataset. Wind atlases and wind maps have been produced in a very wide range of scales, from the world level down to the local government region, and represent the best estimate of the wind resource across a large area. In some areas, 'wind maps' may be available which include the effects of the terrain and ground cover. This may take the form of a ' wind atlas,' which represents the wind speed over flat homogenous terrain, and requires adjustments to provide a site-specific wind speed prediction to be made with due consideration of the local topography. Typically, these wind-mapping programmes will derive a graphical representation of mean wind speed (for a specified height) across an area. These models must be primed with some values at a known location, and usually this role is fulfilled by local meteorological station measurements or other weather-related recorded data or extracted from numerical weather prediction models, such as those used by national weather services. On a broader scale, wind speeds can be modelled using computer programmes, which describe the effects on the wind of parameters such as elevation, topography and ground surface cover. This is, however a fairly costly, and time-consuming process. The best, most accurate indication of the wind resource at a site is through on-site measurement, using an anemometer and wind vane (described in detail later in this chapter). The wind resource is usually expressed as a wind speed or energy density, and typically, there will be a cut-off value below which the energy that can be extracted is insufficient to merit a wind farm development. Wind is ubiquitous, and in order to make the choice of potential project sites an affordable and manageable process, some indication of the relative size of the “wind resource” across an area is very useful.
