This section presents a summary of wind resource studies: Angola has a wind potential of 3,9 GW, of which 604 MW, or 13 projects, have conditions for grid connection by 2017.

The analysis of the wind resource for Angola territory involved the mesoscale modeling by the use of WRF model (Weather Research and Forecasting), with a resolution of 3 x 3 km, for a time horizon of 3 years of data selected from a analysis of climate variability of large-scale, including global climate data from the Reanalysis Project of NCEP/NCAR.

Based on the mesoscale results, all the sites that had, simultaneously, average wind speeds greater than 6.0 m/s, a closeness of less than 100 km from a potential power grid interconnection point, access roads within a 5 km radius and did not cover any classified areas, as natural and/or protected areas, were selected.

In this first phase over 30 locations were identified, mostly  distributed among the NW and SW quadrants of Angola, which enforced the referred criteria.
The second phase of the work consisted in on-site validation for the selected sites through technical visits, having been covered to that effect, in about a month, 11 provinces and more than 4,500 km.

Using the mesoscale results, and for 13 sites validated in the field, a virtual mast was extracted to reproduce the real measurement conditions, with which annual and seasonal average conditions of wind resource mappings were produced for each site using specific microscale modeling software.


Despite not being a country with high wind potential, Angola has still a wind potential of about 3.9 GW. This potential results from the integration of several variables and conditions, including: areas with average wind speeds above 6.0 m/s; areas outside reserves or natural protection and areas with favorable technical conditions in terms of terrain and accessibility.

From the total potential of 3.9 GW of potential projects, 604 MW (13 projects) were considered as priority projects due to their conditions of immediate grid connection in the 2014-2017 horizon. These priority projects have in general average wind speeds above 6.5 m/s, which translates into a capacity factor of about 33% . Projects with these characteristics can compete, in terms of generation cost, with other generating sources, either renewable or conventional.


From the 18 Angolan provinces, Cuanza Sul province stands out, not only for the 300 MW of potential projects, but also for being the province in which the project with the lowest cost of generation was identified - Quitobia 100 MW Wind Project - to be confirmed through field measurements.


The levelized cost of energy was calculated for the 604 MW of priority projects. This calculation was based on the preliminary project for each of the 13 projects, having been determined the annual capacity of power generation (MWh/year), the average cost of investment (CAPEX), having as reference market prices for the supply of turbines, power lines, substations and access roads and, for last, the average cost of operation
and maintenance of wind farms for 20 years (OPEX).

With these results, 3 scenarios of weighted average cost were generated, and will depend on the guarantees to be given to the investors and on the funding sources (5%, 11% and 15% of weighted average cost of capital). In the intermediate (11%), there are over 300 MW of projects below 150 USD/MWh, mostly in Cuanza Sul province. Should also be noted that in the most aggressive scenario power with cost lower than 150 increases to 584 MW.
