![]() Currently, it provides 150 megawatts electricity to Sudan and Djibouti. The construction of more large dams is foreseen in a Master Plan that aims to bring capacity to 15 GW. Contracts for five large dams have been signed and when completed this year, these dams would increase the installed capacity by more than 11 GW from less than 1 GW in 2008. The largest plant, Belles, began initial operation in May 2010. ![]() Ethiopia is the power¬house of Africa due to its high hydro-power potential. Surface water flows in 12 major river basins, discharging an estimated 122.19 billion cubic meters of water annually. The case study augurs on Ethiopia, the water tower of North-East Africa. Development of the Inga Dam can produce 42 GW that will fuel the economy of the Great Lakes Region. The fact that AfDB has made it a priority is welcome news for the sector. As stated by the Obama Power Africa program, energy is a key ingredient for Africa’s development. Advanced industrialized societies use more energy per unit of economic output and far more energy per capita than poorer societies, especially those still in a pre-industrial state. Small Hydro turbine System Design Operation procedure, Recommendations and possible economic impact for small hydropower generation are also highlighted.Įnergy development (increased provision and use of energy services) is an integral part of enhanced economic development. The complete design parameters such as, Turbine material, runner diameter, runner length, water jet thickness, blade spacing, radius of blade curvature, turbine power, turbine speed, number of blades, and any losses in the pipe due to friction, were determined at maximum turbine efficiency. Using mathematical analysis a complete design of such turbines has been done in this paper. The cross-flow turbine is suitable for installing small hydroelectric power plants in case of low head and flow rate. This paper addresses power generation for rural applications by means of small hydropower plants by using cross-flow turbine systems. Small-scale hydro is in most cases " run-of-river ", with no dam, and is one of the most cost-effective and environmentally benign energy technologies to be considered both for rural electrification in less developed countries and developed countries for further hydro developments countries(like Ethiopia). Abstract-Hydropower, large and small, remains by far the most important of the " renewable " for electrical power production worldwide.
