oa East African Geographical Review - East African record the generation of hydro-electric power on the lower Pangani river
The most important aspect of the development of the Pangani river basin has so far been the exploitation of its high hydro-electric potential which derives from a combination of favourable factors. The successive rapids on the lower reaches of the river provide a head of water which facilitates the installation of hydroelectric power plants. The Pangani has a high minimum flow mainly due to the contribution of a number of springs in the foothills of Kilimanjaro. The character of the river permits a gradual expansion of generating capacity and therefore avoids the problem of spare capacity consequent upon a large investment while the demands for power grows. Much the most important of these considerations, however, is the fact that the bulk of the power generated in Tanzania is consumed in the north and east, that is in the Coast, Tanga. Moshi and parts of Arusha and Morogoro Regions and all these can be economically supplied with hydro-electric power from the Pangani.
