Ethiopia is among countries which has very low modern energy sources. The topographic feature and the available water of Ethiopia permit to have a large hydropower potential. However, as the available runoff in rivers has very high hydrological variability, tapping in to this potential require investment on storage to smooth the temporal hydrological variability. In this paper, first the behaviour of this hydrological variability and implication of water resources development is discussed. Secondly, various documents and reports provide varying values of hydropower potential of Ethiopia and Abbay. To close the information gap, topographical and hydrological site evaluation for the selected hydropower potential sites have been carried out, for 129 possible potentials sites which are identified by WAPCOS in 1990 and having total capacity of 13,845 MW. After evaluations these sites 91 possible sites with potential of 12,148 MW are identified and mapped under various sub-basins. Dabus sub-basin stands first among the 16 sub-basins by 13 hydropower potential sites and these sites give 3524MW. In order to exploit the available hydropower potential in the country, it is crucial to rank these sites. The ranking of these sites have been carried out based on cost per kilowatt hour of the hydropower potential (HP) sites. Furthermore, the paper discusses the benefits and tradeoffs for four priority development identified by ENTRO as Eastern Nile fast track projects.

Study region: Eastern Nile River Basin (Ethiopia, Sudan and Egypt).
Study focus: This study aims to understand the future water development perspective in the Eastern Nile region by considering the current water use situation and proposed reservoirs in the upper Blue Nile (Abbay) River basin in Ethiopia using a simulation approach. The study was carried out by using a monthly time step and historical ensemble time series data as representative of possible near future scenarios. Series of existing and proposed cascaded water development projects in the upper Blue Nile were considered in the study.
New hydrological insights for the region: The results indicated an overall energy gain in the Eastern Nile region increases by 258%. The upstream country Ethiopia can generate as much as 38200 GWh/year of Energy while the energy production in Sudan increases by 39%. The cascaded developments integrated with existing water resources systems have a performance efficiency of above 92%. This study was an indicative analysis of the potential benefit of upstream Nile development without significantly affecting existing development in the Nile Basin. Further scientific analysis in this direction would help the Nile countries to reach a water use agreement.
