Content of the Wind Atlas

The Wind Atlas 2003 for Ireland is calculated for different heights above ground level on a nationwide 100 metre horizontal grid basis.  It displays wind speed maps for the entire country, and for each county, plus information about the location of the electricity network at both national and county levels.  The Wind Atlas 2013 covers the same detailed 100 metre grid.  However, it does not include wind speed averaged on a county basis, as this concept has limited relevance for planning or engineering purposes.

The Wind Atlas 2003 displays wind speeds at 50, 75 and 100 metres above ground level, tiled over Ordnance Survey Ireland (OSI) maps. The Wind Atlas 2013 displays wind speeds at 20, 30, 40, 50, 75, 100, 125 and 150 metres above ground level.

Wind speeds can be accurately measured at any location in the country, but the three heights represent the hubheights of current and future wind turbine technology .

Offshore, wind speeds have been mapped to a distance of 25 kilometres from the Irish coast. The wind resource displayed here has been constrained to exclude areas where wind energy projects will not be permitted such as areas where seabed cables and gas pipelines are located, indicative navigation channels, Department of Marine traffic separation / exclusion zones, Department of Defence Danger Areas and near-shore anchorages.
