Presently, in Namibia, RE technologies are being widely used mostly for off-grid energisation and domestic water heating. Successful bigger RE projects, however, are found scattered in isolation all over the country. The most recent project and probably biggest is the wind park close to Lüderitz that is expected to be completed by mid-2013. Other examples are the first commercial solar power plant in Namibia, which is due to commence in the future, and will be divided into 10 MW each at Gerus, Osana and Kokerbook, the equipment of the Shamalindi Primary School near Grootfontein with a solar plant and the complementing of UNAM’s Northern Campus in Ongwediva with a grid-connected Solar Photovoltaic system, which was at the time the largest of its kind in Namibia.Furthermore, an initiative by the Austrian government, which ran until May 2012, aptly named Southern African Solar Thermal Training and Demonstration Initiative (SolTrain), assisted Southern African countries, including Namibia, to switch from a fossil fuel based energy supply to sustainable energy supply systems based on RE by setting up RE demonstration units at social institutions such as hospitals, orphanages and old people’s homes. Last but not least, almost all farms using wind pump installations for water are, in turn, forming small PV-wind hybrid islands all over the country.SolarNamibia has one of the best solar regimes in the world with an average high direct insolation of 2,200 kWh/m2/a and minimum cloud cover. The principal climatic indicator determining the technical potential for solar PV is the global horizontal irradiance (GHI). The areas with the highest GHI are mostly located in the western part of Namibia, from north to south.One of the major solar PV applications in Namibia is the solar water pumping (PVP) in the cattle farms. Solar PV is also use for rural access to modern energy. It consists in small system equipped with an inverter and a storage system (batteries) that provide enough electricity for lighting, radio, TV or fans. Larger solar home systems are also utilized by households having a substantial consumption. They can feed the grid without license if the system is smaller than 500 kV. However, there is no compensation from the power utility. There is no large commercial solar PV plant in Namibia to date.WindNamibia has one of the best wind RES in Africa since it is located in in the more extreme latitudes, away from the atmospheric heating and the earth’s rotation negative impacts. A wind assessment project was carried out by MME and GTZ in 1996 for the region of Luderitz and Walvis Bay (southern coast of Namibia). It showed that both sites have potential for wind power with wind speed around7 m/s. The methodology included a model analysis (WAsP and WindPro Programme) as well as ground measurement (10 m). Recent measurements at 85.7 meters high undertaken in Lüderitz by a potential wind IPP predict a yearly wind speed average reaching 10 m/s with a stable wind direction . Additional potential sites with good wind regime are likely to exist in areas located more in the North (e.g. Henties Bay, Terrace Bay, Mowe Bay). The SAPP has estimated the Namibian potential for wind at 27.201 MW and 36 TWh per year with a relative land use of 824,268 km2.There is currently one wind turbine (220 kW) installed in Namibia. It feed the distribution grid in Erongo Region.Biomass & BiogasIn Namibia, immense land areas are infested with invader bush. It is an important environmental concern because the bush encroachment limits the local biodiversity, the water absorption in the soil and the carrying capacity of livestock. It has been calculated that 26 million hectares of land are invaded in Namibia. With this amount of bush used to produce electricity, the same calculations shows that the potential generation would be 1,100 TWh which at the Namibian scale can be considered as unlimited. Most of this resource is located in the north of the country. The development of Jatropha-based biofuel is potentially high in the north-west of Namibia, i.e. Caprivi and Kavango regions.From 2007 to 2010, the project Combating Bush Encroachment for Namibia’s Development (CBEND) funded by the European Union (N$ 14 million) established the first bush to electricity demonstration plant (250 kW) in Namibia. It was also the first PPA signed by Nampower with an IPP. However, the power plant does not feed electricity yet due to the low power factor of the connecting line.HydroNamibia’s only perennial rivers are the Kunene, Kavango (forming borders with Angola and Zambia in the north) and the Orange River bordering South Africa in the south.In 2010, 64% of the electricity was generated with Ruacana hydropower plant. Ruacana hydropower has now a capacity of 332 MW.Nampower is examining the possibility of installing a second hydropower plant on Kunene River, downstream to Ruacana. The project (Baynes Hydro) has been in the pipelines for many decades. However, political tensions with Angola as well as socio-environmental concerns have restricted the project to a feasibility study. Nowadays, the perspective to supply Southern Africa from a large hydropower plant has raised interests for both parties. The estimated project implementation cost is about US$ 1.3 billion (US$ 10 billion).The deployment of small hydropower plants (6 to 12 MW) along the Orange River for a total capacity of 70 MW is examined by Nampower. The estimated cost is around US$ 5 million to U$ 35 million and it is planned to develop the project as a clean development mechanism activity.
