The World Bank estimates that 70 percent of the economically feasible hydro potential in developing countries – and 93 percent of the potential in Africa remains unexploited. As a result, lending for hydro projects by the global financial body exceeded $1 billion last year most of it going toward the development of small-scale or “micro-hydro,” projects.
Such projects typically do not use dams and do not significantly affect natural river flows, are also quicker and easier to set up. If you install a large power plant, there are also transmission costs to get electricity into rural areas. Micro-hydro means power is generated where it is needed. It’s more cost-effective and it means communities can be self-sufficient in electricity.
Levek Turbines design, install and commission a 150 kW hydro power plant in Télimélé in Guinea large enough to drive a small local economy and provide light for a community of 5000 persons. At first only 20 kW was used, but rapidly as users got thrust in the reliability of a 24 hours electricity supply power demand went up to 100 kW and this within the first year of operation. It is understood that power increased was caused one half by an emergent local economy and the other half by the electrification of housing.
