Ethiopia’s contribution to the Nile River is about 85% of average annual flow of 84 Billion m3 at the High Aswan Dam. Ideal water storage gorges are located in Ethiopia which can generate clean energy and lead to significant flood regulation and overall long-term water saving due to reduced evaporation for all riparian countries. Great Ethiopian Renaissance Dam (GERD) with gross storage capacity of 74 BCM (and year to year varying live storage of 25 BCM) generates clean energy of 15,860 GWh/year benefiting to all riparian countries This paper presents key highlights of the Great Ethiopian Renaissance Hydropower Dam and impacts of GERD to Ethiopia, Sudan and Egypt and for the regions as a whole in the light of Climate Change scenarios based on various river basin simulations studies conducted in the Nile basin.
