All Authorities need to assess the potential for low, medium and high wind resources within their respective areas. In Wales the WG (Welsh Government) have produced a publication entitled 'Planning for Renewable and Low Carbon Energy - A Toolkit for Planners' in 2010.
I've attached a 'How to' guide which attempts to work through the toolkit using Grass and QGIS 1.8 to interpret the guide as we understand it. This includes a detailed description of how to import ascii files into Grass GIS to display as a raster layer.
