Geothermal Projects Site Selection - Zambian Case


[Zesco, Zambia]

Although there is no evidence of recent volcanic activity in Zambia, there are numerous hot and mineralised springs. Most of them related to relatively young faults affecting Karroo rocks, and some of them related to the rift system of East Africa. Historic work includes a countrywide reconnaissance study and the installation of a geothermal pilot power plant at Kapishya. The reconnaissance study of fifty (50) hot or mineralised springs or groups of springs was conducted between 1971 and 1974. Measurements of water temperature, discharge and radioactivity were made, the geological setting was studied, and samples of water and chemical deposits collected for analysis. More detailed investigations were made at a few springs of outstanding interest. (Legg, 1974). However only three geothermal sites (Kapishya, Lubungu and Chongo) have been prioritized in the first phase of the studies. The methodology applied in the selection of geothermal sites to be considered for assessment of power generation included the following aspects: Physical, Social Economic and Technical suitability of the area
