mean annual inflows. The storage capacity of the country''s large dams has historically been around 0.37 km3. While the Dikgathong Dam provides an additional 0.4 km3 in capacity, Botswana has one of the lowest per capita storage capacities in southern Africa. Most dams have been constructed for urban water
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
