This version of our map shows the areas designated by the Welsh Government with presumption in favour of large-scale wind energy development. Planned and existing wind farms are also shown.
The map data for Pre-assessed areas is supplied from DataMapWales and as such contains public sector information licensed under the Open Government Licence v3.0.
There are no included details for turbine locations, solar or proposed transmision lines with pylons or wood poles. For this type of information please see our main map.

Information is copied from our main map. Representation is best effort and based on available information. Area boundaries for wind farms are simplified or approximated only and are not in any way definitive. They are also likely to change in future.
Wind farm circle markers indicate locations where not much else is known. Speculative wind farms, shown in pink, are known from minimal information, often by company name only and located with reasonable probability derived from that name (optional display in the layer menu).
The base map can be changed between Open Street Map, Open Topographical Map or Satellite - select from the layers menu at the top-right corner.
Information presented on this map is not guaranteed as acurate, but the features are intended to give a reasonably good idea of location. With that in mind, any part of the map may be reproduced for non-commercial purposes. This map is produced by Deeproot Software using the open source Leaflet JS library.
