Ethiopia will start generating power from its controversial mega-dam on the Blue Nile from Sunday, government officials told Agence France-Presse (AFP).
The Grand Ethiopian Renaissance Dam (GERD), set to be the largest hydroelectric project in Africa, has been at the center of a regional dispute ever since Ethiopia broke ground in 2011.
"Tomorrow will be the first energy generation of the dam," an Ethiopian government official said on Saturday.
A second official confirmed the information. Both spoke on condition of anonymity because the milestone has not been officially announced.
Ethiopia's downstream neighbors Egypt and Sudan view the dam as a threat because of their dependence on Nile waters, while Addis Ababa deems it essential for its electrification and development.
The $4.2 billion (3.7 billion euros) project is expected to produce more than 5,000 megawatts (MW) of electricity, more than double of Ethiopia's electricity output.
Ethiopia had initially planned output of around 6,500 MW but later reduced its target.
"The newly generated electricity from the GERD could help revive an economy that has been devastated by the combined forces of a deadly war, rising fuel prices and the COVID-19 pandemic," said Addisu Lashitew of the Brookings Institution in Washington.
The dam is built on the Blue Nile River in the Benishangul-Gumuz region in western Ethiopia, not far from its border with Sudan.
No breakthrough in talks
Talks held under the auspices of the African Union (AU) have failed to yield a three-way agreement on the dam's filling and operations and Cairo and Khartoum have demanded Addis Ababa to cease filling the massive reservoir until such a deal is reached.
But Ethiopian officials have argued that filling is a natural part of the dam's construction process and cannot be stopped.
The United Nations Security Council met last July to discuss the project, although Ethiopia later slammed the session as an "unhelpful" distraction from the AU-led process.
In September, the Security Council adopted a statement encouraging Egypt, Ethiopia and Sudan to resume negotiations under the AU auspices.
Egypt claims a historic right to the Nile dating from a 1929 treaty that gave it veto power over construction projects along the river.
A 1959 treaty boosted Egypt's allocation to around 66% of the river's flow, with 22% for Sudan.
Yet, Ethiopia was not party to those treaties and does not see them as valid.
The process of filling the GERD's vast reservoir began in 2020 with Ethiopia announcing in July the same year it had hit its target of 4.9 billion cubic meters (bcm).
The reservoir's total capacity is 74 bcm and the target for 2021 was to add 13.5 bcm.
Last July, Ethiopia said it had hit that target, meaning there was enough water to begin producing energy, although some experts had raised doubts over the claims.
