Bhutan Resource Maps

This page contains high-resolution wind and solar resource maps and data products for Bhutan. The high-resolution (1-km) annual wind power maps were developed using a numerical modeling approach along with NREL's empirical validation methodology. The high-resolution (10-km) annual and seasonal solar resource maps were developed using weather satellite data incorporated into a site-time specific solar mapping approach developed at the U.S. State University of New York at Albany.

Data products from the wind and solar maps have been output in a geographic information system (GIS) format. You can examine the resource data in a geospatial context along with other key information relevant to renewable energy development, such as transportation networks, transmission corridors, existing power facilities, load centers, terrain conditions, and land use. Users can incorporate location-specific data directly into the micropower optimization model, HOMER, to design least-cost hybrid renewable power systems to meet electric-load requirements at the village level.

These products were developed by the U.S. National Renewable Energy Laboratory (NREL) for the U.S. Agency for International Development's (USAID) South Asia Regional Initiative for Energy (SARI/E). Access the Bilateral Partnerships page for more on NREL's work with SARI/E.
