IrSOLaV performs First Phase of solar radiation mapping in Tanzania for World Bank

IrSOLaV, as one of the most competitive companies as an international provider of solar resource and meteorological data, has been involved in the project: “Solar Resource Mapping : Armenia”, funded by the World Bank (World Bank). IrSOLaV is part of a consortium formed by CENER and Geonica.

Tanzania has tremendous potential for harnessing solar renewable energy resource to help reduce power cuts and improve access to modern energy services. But the country lacks the high-quality resource data at a national scale that is needed to take full advantage of these sources of clean energy.

The country’s resources suitable for solar power generation are estimated to be equivalent to those of Spain, and areas of high wind power potential cover more than 10 percent of the country, an area the size of Malawi, and a greater potential than the US State of California, according to the findings. “Tanzania has big plans for generating electricity from renewable energy resources, so there is a need for clear information on potential geographic concentration, as well as seasonal and daily availability of these resources,” said Felchesmi Mramba, Managing Director of the Tanzania Electric Supply Company (TANESCO), the country’s national electricity utility, speaking at a media briefing on the findings held in Dar es Salaam on May 22, 2015.

For the past year, the World Bank have been working together to map renewable energy resources across the entire country. The project, supported by the World Bank’s Energy Sector Management Assistance Program (ESMAP), will measure Tanzania’s potential for wind and solar energy by using ground-based data collection, GIS analysis, and geospatial planning. It is part of a broader Renewable Energy Resource Mapping initiative covering 12 countries.

Concluding the first phase of the project, initial maps of solar potential for Tanzania were presented to the government and other stakeholders at a workshop in Dar es salaam. The result of months of computer-intensive modeling, these maps represent a significant improvement over previous efforts due to computational advances over the last decade. The maps are based on satellite data, global atmospheric models and numerical weather prediction models covering more than 11 years period (solar cycle), and can be used to estimate the likely solar or wind potential at any point in the country. However, to get to the level of confidence required by commercial developers, these modeling results must be compared against actual solar and wind measurements taken from ground-based stations. A major part of the ESMAP renewable energy mapping initiative is to collect ground-based measurement data for a period of up to two years. This data is then used to improve the models, leading to the production of solar with a minimum margin of error. This in turn can be used by governments to set tariffs and guide the strategic development of renewable energy, and by commercial developers to carry out feasibility studies, leading to the development of solar power plants.

During the workshop held in the capital Dar es salaam the first radiometric station was installed in the main University of the city.
