Overview
- The Grand Ethiopian Renaissance Dam, begun in 2011, is set for a formal opening on September 9 after works costing about $5 billion near the Sudan border on the Blue Nile.
- The 1.8‑kilometer‑long, 145‑meter‑high structure with a 74‑billion‑cubic‑meter reservoir has been operating since early July and is expected to roughly double Ethiopia’s electricity output.
- Prime Minister Abiy Ahmed argues the project will drive regional development and says downstream reservoirs have not lost water because of the GERD.
- Egypt, which relies on the Nile for about 97% of its water and reports a large supply gap, has intensified warnings, with President Abdel Fattah al‑Sissi vowing to use measures permitted under international law.
- Sudan has joined Egypt in rejecting unilateral actions, past mediation attempts by the US, World Bank, Russia, UAE and African Union have failed, and experts judge a military clash unlikely as focus shifts to adaptation.
