Answer Text:
- High seasonal fluctuations in the flows of the river regime especially in times of drought
- Inadequate capital since H.E.P require high capital outlay which many African countries lack and they rely heavily on foreign aid
- Poor maintenance of machinery at power production stations caused by inadequate capital to buy spare parts for the machines
- Siltation of reservoirs caused by poor farming methods upstream and lack of machinery to remove the silt from the reservoirs
- Small markets for HEP hinder production due to high poverty level of the population found in the counties
- The big rivers such as Niger, Nile, Volta, Zambezi and Orange have their waters reduced by evaporation because they pass across dry regions.
