NAIROBI: Ethiopia said it has more than doubled electricity production from its controversial mega-dam on the Blue Nile after two more turbines started operations. The multibillion-dollar Grand Ethiopian Renaissance Dam, long a source of tensions with downstream nations Egypt and Sudan, is now generating 1,550 megawatts of electricity, GERD said in a post on X late Tuesday. “The overall progress of the GERD has now transitioned from construction phase to operation phase,” it said, adding that construction of the concrete dam was now complete. “The two turbines generating 400MW each have now started operations, adding to the already functional two turbines generating 375MW each, totaling an output of 1,550MW.” The dam’s spillways were also releasing an extra 2,800 cubic meters of water to the downstream countries, it added. Ethiopia first began generating electricity at the $4.2-billion project, which is located in the northwest of the country around 30 kilometers (18 miles) from the border with Sudan, in February 2022. At full capacity, the huge dam — 1.8 kilometers long and 145 meters high — could generate more than 5,000 megawatts of power when all 13 turbines are operational. That would make it Africa’s biggest hydroelectric dam and more than double Ethiopia’s current output. Addis Ababa deems the GERD essential for the electrification and development of Africa’s second most populous country. According to the World Bank, roughly half of the 120 million population still does not have access to reliable electricity. The dam, which can hold up to 74 billion cubic meters of water, has been at the center of a regional dispute ever since Ethiopia broke ground on the project in 2011. Egypt and Sudan have voiced concerns about its operation without a three-way agreement, fearing it could threaten their access to vital Nile waters, but on-off negotiations have failed to make a breakthrough.
