Wind energy concept – Swiss federal government basic map of main areas with wind-power potential
The wind energy concept is a concept in accordance with Art. 13 of the Swiss Spatial Planning Act (SPA, SR 700). The concept defines both the principal federal government interests which must be taken into account when planning wind energy plants and the main areas with wind-power potential which must be investigated as part of cantonal structural planning. In this way, the wind energy concept increases planning reliability. The Swiss federal government has identified the main areas with wind-power potential, taking into account the high wind energy yields (basic data from the Wind Atlas of Switzerland, www.windatlas.ch), the principal federal government interests and sufficient spatial concentration. The rough analysis, which is subject to some uncertainty, does not take account of any cantonal or municipal interests and does not permit any assertions to be made about the specific feasibility of wind energy plants. The cartographical representation of the areas with potential should not therefore be seen as a positive plan by the federal government or as competition to structural plan entries that have already been approved; neither does it make any assertions beyond a 1:50,000 scale. The cantons are responsible for identifying suitable areas for wind energy use and the associated balancing of interests appropriate to the relevant levels. The geodata from the main areas with potential are not officially binding but are primarily to be considered as the federal government’s basis for cantons which do not yet have any structural plans in place for wind energy or which want to adapt their structural plans accordingly. In the interests of completeness, the map must be consulted in parallel with the content of the wind energy concept and the associated explanatory report.

Solar irradiation on a surface inclined 90° to the south
The irradiation maps show the solar radiation on a south-facing surface for four different inclinations: Horizontal, 30°, 75° and 90°. The data is based on Switzerland-wide modelling with a horizontal grid width of 50m. It is based on measurement data from the period 2000-2020 and the influence of the horizon was derived from a 10 m resolution elevation model of Switzerland and neighbouring countries. In addition to the global radiation, the expected photovoltaic production per kW of installed capacity is also shown for the respective irradiation levels. The data can serve as an initial estimate of potential PV production. However, depending on local conditions and system design, the value may be higher or lower. For example, any additional yields resulting from the use of bifacial modules were not taken into account. Under "Additional information", the monthly values of global radiation (per m2) and expected photovoltaic production (per kW of installed capacity) can be queried for each grid point. Further information on the modelling can be found in the report under the link "Data reference".

Wind Atlas of Switzerland: Annual average of the modelled wind speed and direction at a height of 50 metres above the ground
The Wind Atlas of Switzerland describes the wind conditions at five different heights above the ground: 50, 75, 100, 125 and 150 metres. The data are based on a nation-wide modelling system with a horizontal grid width of 100 metres. The modelled average annual wind speed is depicted in the atlas at each grid point. The classification of wind speeds into categories can be approximated with the aid of Weibull parameters A (scale parameter) and k (shape parameter). It is not possible to directly derive the average wind speed from the Weibull parameters because the result is only an approximation to wind distribution and this cannot be adequately reflected for each location. The wind rose shows the relative frequency of the modelled wind directions. The averaged wind speeds and corresponding Weibull parameters are visible for each sector. The calculation of wind speeds and directions is based on long-term measurements that have been incorporated into the models. Because the measurement points are not available everywhere throughout the country at a suitable density, and inaccuracies can occur in the modelling of wind flows in complex terrain, the results are subject to uncertainties. These range from +/- 0.5 metres per second in the Jura range, +/- 0.7 metres per second in the central plain and +/- 0.5 metres per second in the pre-Alps, to +/- 1.3 metres per second in the Alps. For maps at heights of more than 100 metres above the ground, significantly fewer measurements are available for modelling purposes, and this leads to increased uncertainties in the results. The data have to be regarded as rough estimates of the wind conditions. To assess the wind conditions at a specific location, measurement on site is therefore essential.
