The Nanyang Technological University posted on 29 July 2025 an article titled "Ethiopia Wraps Up Construction of Africa's Largest Hydro Project."
Ethiopia has completed construction on the Blue Nile of the $4.2 billion Grand Ethiopian Renaissance Dam, Africa's largest hydroelectric project. In addition to meeting domestic demand for electricity, Ethiopia is now selling it to Kenya, Sudan, Djibouti, and Tanzania. The article comes with an excellent picture of the completed dam.
Comment: This article makes the same mistake that most reporting makes on this topic by stating that the Blue Nile provides 85 percent of the Nile River's total flow. The Blue Nile contributes closer to 55 percent of the Nile River's flow. A combination of the Blue Nile, the Tekeze that feeds directly into the Nile, and the Sobat that feeds into the White Nile contribute about 85 percent of the Nile River's flow. The Blue Nile is the single most important source of water for the Nile. All three of these rivers originate in Ethiopia. Their names change as they cross international borders.
