Accurate estimation of renewable energy potential is apreliminary exercise for mini-grid development. While information on solar and wind resources is becoming more readily avialable from satellite imagery and regional meteorological stations, technologies like small hydro and biomass gasifiers require detailed resource assessments at the site. In any case, despite the readily available information about solar and wind potential it is avisable to look at all possible technologies for a particular site as hydro power and biomass gasification can be more economically attractive.
The following sections provide information and links to resources on how to carry out resource assessments for individual renewable energy technologies.
Approach for renewable energy resource assessment
The following figure provides possible ranking of technology choces based on the availability of sufficient renewable energy resources.
Hydro
In the area of hydro power GIZ has developed several guides on resource assessment. For more information:
Biomass
The process of biomass estimation andmethodology of calculation is methodical in nature. Different Biomass estimationmethodologies are used for resource estimation. Land records and cropproductivity in these lands are procured from relevant revenue, forest, agriculture
and research organizations. The vegetation cover, regional socioeconomic,biomass extraction processes, extraction pricing as well as management regimesmay differ depending on the ownership pattern existing in the region over land aswell as resources.
