Annual energy production of hydropower plants

Many African countries, especially in the Sub-Saharan region, highly depend on hydropower, which is one of the energy sources most affected by droughts. At the same time, hydropower has a huge impact on water consumption (mainly through evaporation from reservoir surfaces) in comparison with other fuel types despite having higher densities of plants and installed capacities. Hydropower accounts for 15% of Africa’s energy production. This map shows the location and annual energy production (GWh/year) of hydropower plants with an installed capacity above 5MW in Africa for year 2016.

Annual gross water loss vs annual energy production of hydropower plants (mcm/GWh)

In 2016, a total of 42 billion cubic meters of water was lost through evaporation in hydropower reservoirs in Africa. A huge amount compared to the 1.2 billion cubic meters lost from all the other fuel types combined. In the same period, hydropower accounted for 15% of Africa’s total energy production. The ratio of annual water loss (from a hydropower reservoir) versus energy production (of the associated hydropower plant) describes somehow the water efficiency of a hydropower site. The ratio varies from region to region and depend on the reservoir’s surface area and evaporation rate, and on the produced energy of the associated hydropower plant. A better performance (lower ratios, i.e. ratios below 1) in terms of reduced water losses through evaporation per produced energy unit can be achieved at hydropower sites characterized by decreased reservoir surfaces and increased energy production. In contrast, unfavourable, higher ratios occur with water losses higher than the associated hydropower energy production rates. This map shows the location and ratio water loss / energy production (mcm/GWh) of hydropower plants in Africa for year 2016.
