The Energy Sector Management Assistance Program (ESMAP) is a partnership between the World Bank and 24 partners to help low and middle-income countries reduce poverty and boost growth through sustainable energy solutions. Through the World Bank Group (WBG), ESMAP works to accelerate the energy transition required to achieve Sustainable Development Goal 7 (SDG7) to ensure access to affordable, reliable, sustainable and modern energy for all.


The International Electrotechnical Commission (IEC) publishes International Standards, which together with conformity assessment provide the technical framework that allows consistently safe and reliable products.

The Global Wind Atlas version 3.3 includes exciting new features and improvements. Viewing of any layer on the Global Wind Atlas can now be masked with data from any other layer, and the new IEC Class layers make it possible to quickly assess the IEC Class for wind turbines and wind farms.

DTU Wind and Energy Systems has today released the Global Wind Atlas (GWA) version 3.3, and this new version of the free and web-based application represents a significant upgrade. As such, the GWA continues to help policymakers, planners and investors identify global, national, regional and local high-wind areas for wind power generation. DTU would like to acknowledge the funding provided by the World Bank’s ESMAP, as well as advice and review provided by its staff and consultants.


In GWA 3.3, DTU and Nazka Mapps introduce an important improvement, which facilitates viewing any layer masked with data from any one other layer. It is also possible to adapt the minimum and maximum value of the mask (e.g. view mean wind speed map masked with data from bathymetry map, hiding the mean wind speed for water depth beyond 50 meters and showing areas which can potentially be feasible with current fixed foundation technologies).


GWA users who are interested in site suitability will appreciate the three new IEC Class layers (under the Wind Energy Layers), mapping IEC wind turbine classes for 100m wind turbine hub height and making it possible to quickly assess the IEC Class of wind turbines and wind farms. The IEC Class layers in the GWA were produced by the project Global Atlas of Siting Parameters. For more information about these three map layers, please refer to the Datasets page of the GWA.


Users of the Energy yield calculator tool will appreciate that it is now possible to view the result on the map. The calculation speed has also been improved, allowing for users to calculate and view energy yields for larger areas.


The Global Wind Atlas is developed, owned and operated by DTU, Technical University of Denmark. DTU wishes to thank all organizations and individuals involved in the development of the GWA 3.3, including those not listed above, who have provided important input data, advice, review, and feedback.
